Audi A8 hybrid to start series production in 2012

The power of a six-cylinder model, the fuel consumption of a four-cylinder version: Audi will be starting series production of the A8 hybrid in 2012. Its gasoline engine – a 2.0 TFSI – and an electric motor develop peak output of 180 kW (245 hp) and 480 Nm (345.03 lb-ft) of torque. Average fuel consumption is below 6.4 liters per 100 km (36.75 US mpg). The sedan can travel at speeds of up to 100 km/h (62.14 mph) on electric power alone, and cover around three kilometers (1.86 miles) with zero local emissions at a constant speed of 60 km/h (37.28 mph).

The Audi flagship model is designed as a highly efficient parallel hybrid. The 2.0 TFSI, which has been modified in some areas, generates an output of 155 kW (211 hp) and 350 Nm (258.15 lb-ft) of torque, which is available between 1,500 and 4,200 rpm. The combustion engine works together with a disc-shaped electric motor which develops 40 kW (54 hp) and 210 Nm (154.89 lb-ft).

The permanent magnet synchronous motor is mounted in the space usually occupied by the torque converter in front of the modified eight-speed tiptronic. A multi-plate clutch that operates in an oil bath connects or disconnects the electric motor and the TFSI engine. The clutch operates ultra-precisely and gently in all situations. The highly comfortable and fast-shifting hybrid transmission guides the torque to the front wheels; with its wide gear spread it contributes to the efficiency of the Audi A8 hybrid.

The short-term system output of 180 kW (245 hp) and the system torque of 480 Nm (354.03 lb-ft) ensure highly agile performance. The Audi A8 hybrid reaches 100 km/h (62.14 mph) in 7.7 seconds from a standing start and has a top speed of 235 km/h (146.02 mph). Its fuel consumption in the EU cycle is less than 6.4 liters per 100 km (36.75 US mpg), and CO2 emissions are below 148 grams per km (238.18 g/mile). Please note that all figures are provisional.

The Audi A8 hybrid can drive at up to 100 km/h (62.14 mph) purely on electric power and has a range of up to three kilometers (1.86 miles) at a constant 60 km/h (37.28 mph). This gives the driver the choice of three modes: The EV characteristic map gives priority to the electric drive, while the D mode efficiently controls both the engine and the electric motor. The S mode and the tiptronic gate are designed for a sporty driving style. The hybrid sedan has five operating states: with the TFSI engine alone, with electric drive only or in hybrid mode; recuperation and boosting are also possible. Two displays show the driver all operating modes in detail.

The lithium-ion battery, which weighs 36.7 kilograms (80.91 lb), is located in a crash-proof area in the trunk. It provides 1.3 kWh of nominal energy and up to 40 kW of power. Two different methods are used to air-cool the battery, depending on need: with air blown from the passenger compartment by a fan and via a separate cooling circuit coupled to the automatic air conditioning system. The battery is thus kept within the temperature window required for it to perform to its full potential over a wide range. The electric motor and the compact power electronics which serve as a controller between the electric motor and the battery are water-cooled.

In visual terms, the Audi A8 hybrid is distinguished by subtle details. The ten spokes of its alloy wheels – which have a diameter of 18 inches as standard and 19 inches as an option – are reminiscent of turbine blades. The body features hybrid badges, and Arctic Silver is available as an exclusive paint finish. The metallic paint finish, three-zone automatic air conditioning, LED headlights and the BOSE sound system come standard.

Thanks to the brand’s ultra-lightweight construction expertise, the Audi A8 hybrid will be one of the lightest sedans in its category. Its ASF (Audi Space Frame) body is made entirely of aluminum, while the B-pillars are of hot-shaped, ultra-high-strength steel. Weighing just 231 kilograms (509.27 lb), it is roughly 40 percent lighter than a comparable steel construction.

Coming soon at ABT - The new Audi Q3



Kempten commitment to maximum urban sportiness - the new ABT Q3



"The Q3 is an extremely athletic yet very elegant vehicle. It combines the powerful aesthetics of a robust car with the shape of a cool coupe", explains Hans-Jürgen Abt. For the CEO of ABT Sportsline, the world's largest tuner of vehicles from the VW Group, the latest offspring of the SUV family represents an absolute highlight in the product range: "In its class the Q3 is something special. For our designers it provides the perfect working basis, as it is both classy and dynamic", states Hans-Jürgen Abt. For example the Abts were able to further accentuate the unique tornado curves of the Q3 with side sills. In connection with the striking ABT front grill and the front spoiler the inherently compact car seems more powerful and to have more presence. The rear wing, rear apron and exhaust pipe covers ensure that from the rear of the SUV you can see that the car has a good figure.



After all the ABT Q3 does not just look sporty - it is sporty too: the engineers from Bavaria are currently working on the final tests of the individual ABT POWER performance packages. But it is already certain that the new car will provide an additional boost of maximum sportiness and extra driving enjoyment in practically all situations. As a result the most powerful version of the 2.0 TSI is expected to offer 250 HP or 184 kW (series standard: 211 HP/155 kW). The 170 HP version (125 kW) has been converted by ABT Sportsline into a sports engine with 210 HP (154 kW). For SUVs, a diesel engine is of course always a good, economical solution. As a result ABT POWER is also available for both performance levels of the economic 2.0 TDI: the series standard 140 HP (103 kW) is increased to 170 HP (125 kW), while the version with 177 HP (130 kW) as standard offers a high-torque 195 HP (143 kW) after the power treatment by ABT. The turbo diesel with two litre cubic capacity is the first choice if you want a little more, for example if the athletic ABT Q3 is also to be used as a workhorse.



Regardless of which engine is chosen, the customer always receives a vehicle which combines maximum driving fun with everyday usability and reliability. The fact that handling and optics do not have to suffer due to the car's diversity is proved emphatically by the SUV of ABT. And the new Q3 in particular is a really attractive car, its design elements harmonise with the performance improvements - both have been developed as it were from the high demands of ABT customers. Consequently the extravagant light metal alloys from the CR and DR ranges suit the ABT Q3's powerful-robust coupe shape perfectly. It goes without saying that the alloys are also available in combination with strong load-bearing high-performance tyres - in accordance with the commitment to maximum urban sportiness.

2011 Audi A5 luxury coupe

Audi A5 coupe There are eight engines to choose from and a range of trim options. The most popular engines are the diesels, which offer an appealing blend of performance and economy. S line models get even sportier bodywork and bigger wheels, although the latter spoils comfort.

Petrol and diesel engines are smooth and powerful. Range-topping Audi S5 and Audi RS5 models deliver incredible acceleration and feel as butch and brawny as an American muscle car.

With a focus on high performance, Sport and S line versions feature stiffened suspension and bigger wheels as standard, and are not as comfortable as rivals like the BMW 3 Series Coupe. The Audi A5 is a premium car that commands premium prices. However, entry-level models are cheaper than both the BMW 3 Series Coupe and Mercedes-Benz E-Class Coupe. Choose a popular engine and trim - a diesel version in S line specification, for example - and you’ll enjoy solid resale values, which also keeps lease prices affordable.

Any one of the three TDI diesels - 2.0, 2.7 and 3.0-litre - will return manageable fuel economy with varying degrees of performance.

The 2011 Audi A5 coupe delivers sleek, European-influenced styling with a fuel-efficient turbocharged four-cylinder engine. The two-door Audi A5 luxury coupe also incorporates advanced safety features including four-wheel anti-lock brakes, emergency braking assistance and electronic brake force distribution, traction and stability control and front, rear and side airbags to protect driver and passengers in the event of an accident.

Available options on the Audi A5 coupe include heated front seats, a navigation system with rearview parking and backing camera, Bluetooth interface and an upgraded Bang & Olufsen sound system.

The style does matters this is what Audi A5 Coupe speaks about itself. The transmission is either 6-speed manual or 8-speed mutitronic somewhere whereas there is optional 6-speed tiptronic or 7-speed Stronic transmission too.

It’s long elegantly styled V-shaped bonnet, blends smoothly too its low arc shaped roof seamlessly. It is composed of amenities like 6-speakers audio system, climate control A/C, adjustable steering column, Driver Information System with fuel saving tips, Multi-function steering wheel (SE and above trims), Sports Seats ( Sports trim) and Bang and Olufsen Audio system with Bluetooth (Black Edition).

The Black Edition model of "Audi A5 Coupe" in 3.0 TDI QUATTRO engine is priced competitively at £40,810.

Audi to make all Chinese built models mild hybrids [video]

Audi will equip all of its Chinese made models with mild hybrid technology next year according to an interview with Mr Dominique Boesch of the GM of FAW-VW’s Audi sales unit.

The mild hybrid technology can reduce energy consumption by 3-5% said Mr Boesch. They have not made the final decision on pricing.

They are also considering applying mild hybrid technology to the imported Audi models. Mr Boesch also said that they will launch Audi Q5 coming with full hybrid technology in the near future, and then launch all-electric vehicles.

Audi has started to develop new energy vehicles since 1989. It’s also the first automaker to launch hybrid technologies, including mild hybrid and full hybrid. By 2009, Audi had launched five all-electric vehicles.

2011 Audi e-Tron A3

The Audi e-Tron A3 incorporates a 1.4 liter of TFSI turbocharged engine. The engine can produce the power up to 211 HP; meanwhile the motor can produce 27 HP. The top speed of this car is 144 miles per hour.

At first glance, the 2011 Audi e-Tron Concept does not seem like the power house that it is built to be. True to Audi’s philosophy of producing worthy candidates for the car-loving market, the 2011 Audi e-Tron Concept combines the luxury of having a powerful machine and the pleasure of having such an aesthetic work of art in your hands

Audi has taken their Audi E-tron concept a step forward with the unveiling of the E-tron A3 concept - a compact car featuring a powerful electric motor and a liquid-cooled lithium-ion battery. The concept has received a revised instrument cluster, leather Alcantara seats, a heated windshield, and an optimized air conditioning system.

As a hybrid concept, Audi decided to use a different engine than the one found in the A3 Sedan Concept. Of course, being a hybrid concept, performance takes a back seat to fuel efficiency and that’s where the E-tron A3 Concept has the upper hand over the gasoline-powered A3 Concept.

The Audi e-Tron A3 Concept looks remarkably similar to the A3 Concept and there’s a reason for that.
In place of the 2.5-liter turbocharged inline-five engine of the A3 Sedan Concept, Audi put a hybrid powertrain that’s made up of a 1.4-liter TFSI turbocharged gas engine with direct injection and an electric motor with an output of 27 horsepower.

Audi A1 e-tron wins 2011 Silvretta Electric Car Rally [video]

Audi is this year’s overall winner of the second Silvretta Electric Car Rally in Austria’s Montafon region. The 2011 victory of the A1 e-tron follows the R8 e-tron’s win last year. The second Audi in the rally, a Q5 HFC with a fuel cell finished in sixth place. A total of 32 electric vehicles were evaluated.

After three days, 307 kilometers and a total altitude difference of 11,541 meters, the A1 e-tron bearing the number 206 was named the winner of the second Silvretta Electric Car Rally Montafon. The event took place from July 7-9 as part of the 14th Silvretta Classic. The name Silvretta refers to a group of mountains in the eastern Alps of Austria. The Audi A1 e-tron won against 31 competitors in a rally, that was held on highly taxing mountain roads with inclines up to 15 percent, presenting a special challenge to electric vehicles. The Audi Q5 HFC, which was also entered by Audi, achieved sixth place. This was the best final result of all cars with a fuel cell.

The A1 e-tron contains technology that Audi’s development engineers are using to study the mobility requirements for such a future-oriented concept. The technological basis includes an electric motor with a maximum output of 75 kW that is powered by a lithium-ion battery. The battery features a 12 kWh capacity and can be completely charged in 30 minutes (quick charge), or in less than three hours (standard charge). It offers a range of 50 kilometers. To prevent drivers from being stranded by an empty battery, the A1 e-tron also comes equipped with a combustion engine, which can charge the battery as needed. The one-disc rotary engine (254 cc) is located under the trunk floor; it provides 15 kW of output intended solely to charge the battery, rather than to directly power the wheels.

The A1 e-tron is designed with a local emission-free electric drive system, which is ideally suited for driving in a city.

During the rally the A1 e-tron was driven by Franciscus van Meel, Head of Electromobility Strategy at AUDI AG. Long-time Audi employee Gerhard Gruber took on the important role of co-driver. “Sending an electric car into the Alps is one of the toughest challenges you can present it with. The fact that the A1 e-tron proved so impressive here is especially gratifying to me and it proves we’re on the right track with our electric mobility approach of combining an electric motor with a combustion engine . Many thanks to our dedicated team for making our second overall victory in a row possible,” said van Meel after crossing the finish line.

Van Meel then went on to describe the rally itself: “On the first day we drove cautiously and despite a distance of just over 100 kilometers we finished with a lot of electricity left in the battery. On the second day we were better prepared and we were able to win the day; on day three we came in second, and in the end that was enough to win the overall victory. The car ran flawlessly. We’re now looking forward to the 2012 rally. We already have a few ideas about the kind of concepts we’ll enter with, of course.”

UNIQUE AUDI R8 SPYDER REFLECTS WELL ON SIR ELTON'S PARTY

Annual White Tie and Tiara Ball to auction unique ‘chrome' version of celebrated 194mph open-top sports car

Guests at this year's White Tie and Tiara Ball, which as always takes place at the home of Sir Elton John and his partner David Furnish, will need to empty their jewellery boxes to avoid being outshone by the very special R8 sports car donated by Audi for the star-studded event. A dazzling and unique mirror-like chromed finish has been applied to the 194mph open-top sports car especially for the occasion - which takes place on Thursday June 23rd - to attract the highest possible bids in the auction that raises hundreds of thousands of pounds for the Elton John Aids Foundation (EJAF) annually.

"Sir Elton John's fundraising ball really is a golden ticket event that is as glamorous as it is hugely effective in fundraising terms," commented Jeremy Hicks, Director of Audi UK. "We are delighted, and enormously proud, to support it for a ninth year with the donation of what is arguably our most fittingly glamorous model," he added.

The White Tie & Tiara Ball, now in its 13th year, is the EJAF's foremost fundraising event, and has been supported by Audi with special auction lots for the past eight years.

2011 Audi Q5 Hybrid

2011 Audi Q5 Hybrid,According to a new report, Audi will offer the hybrid Q5 in 2011. It was originally thought the Q5 hybrid would hit the market in late 2010, but it remains possible the hybrid Q5 could still launch next year with a 2011 model year designation.It remains unclear what powertrain Audi will mate to the hybrid system.Audi will launch a diesel version of the Q5 sometime after the hybrid model hits the market.

Audi has followed the recent German tradition of slotting the electric motor between the engine and the eight-speed automatic gearbox and using it to replace the torque converter. There's no starter because the electric motor does that job, along with generating 12-volt power to power up the a/c, water pump and power steering.

Audi is anticipating cities adopting "green zones" where you won't be able to drive on internal combustion power, so the "Q5 Hybrid has a full electric mode using the 211Nm, 33kW electric motor".

Audi insists it can hit 100kph as a pure electric car and, at a steady 60kph, the Q5 will run for 3km. Usually, the car's brain turned on the petrol motor far sooner
The Sport mode sees the electric motor team up with the turbo petrol engine to add more urge to the surge on hard acceleration. Hybrids need an imperceptible switch between electric power to petrol power, but the Q5's petrol motor gave a significant shudder when it fired up. It's also quick when both motors are at work. The petrol engine needs to wait until the engine revs build up to its torque peak; the electric doesn't and is like flicking a switch to "Maximum Torque".

The ride quality and interior are virtually unchanged, and the handling doesn't lose anything because there's the extra weight of the battery pack at the back balancing the electric motor up front.

For the first time for the North American market, Audi will offer a gasoline/electric hybrid in the form of the 2011 Q5 Hybrid. Presumably, the Hybrid will come with Quattro all-wheel drive.
Though "Lexus "long ago started offering a "hybrid luxury crossover in the form of the RX 400h, the 2011 Audi Q5 Hybrid" should stand out thanks to a sporty driving experience.

The 2012 Audi Q5 hybrid quattro [video]

The First Full Hybrid in the Premium Mid-sized Class

Power like a V6, fuel consumption like a four-cylinder TDI - after three generations of the Audi duo, the Q5 hybrid quattro is the first hybrid model from Audi with two drive systems. Its gasoline engine, a 2.0 TFSI, and its electric motor have a system output 180 kW (245 hp) and 480 Nm (354.03 lb-ft) for sporty dynamics - the mean consumption in the normal cycle (NEDC) is limited to less than 7.0 liters per 100 km (33.60 US mpg).

During the development process, Audi focused on a high share of electrically powered driving. The sportiest hybrid SUV on the market covers about three kilometers (1.86 miles) locally emission-free at a speed of 60 km/h (37.28 mph), and can drive up to 100 km/h (62.14 mph) under electric power alone. With the equally powerful and lightweight lithium-ion battery and many other solutions, the Audi Q5 hybrid quattro represents the state of the art.

Performance
The 2.0 TFSI and the electric motor of the Audi Q5 hybrid are mounted directly behind one another as a parallel hybrid system - a straight-line concept with impressive efficiency. Together they have a system output of 180 kW (245 hp) and a system torque of 480 Nm (354.03 lb-ft). The new top model in the successful Q5 series sprints from 0 to 100 km/h (62.14 miles) in 7.1 seconds, while the interim sprint from 80 to 120 km/h (49.71 to 74.56 mph) is accomplished in fifth gear in 5.9 seconds. The powerful propulsion ends at no less than 222 km/h (137.94 mph).

The consumption by the Audi Q5 hybrid quattro lies under 7.0 liters per 100 km (33.60 US mpg) in the normal cycle - that corresponds to a CO2 emission of less than 160 g/km (257.50 g/mile). The 75 liter (19.81 US gallon) tank yields a reliable range comparable to that of a TDI.

The Drive
The 2.0 TFSI in the Audi Q5 hybrid quattro has a displacement of 1984 cc (121.08 cu in). Its output is 155 kW (211 hp), with the maximum torque of 350 Nm (258.15 lb-ft) permanently available at 1500 to 4200 rpm. The 4-cylinder engine combines direct injection with turbocharging - typical for the Audi philosophy of downsizing, which replaces displacement by charging. The Audi valve lift system (AVS) further increases power, torque and efficiency by switching the stroke of the exhaust valves between two stages depending on the load and rpm.

The 2.0 TFSI has been overhauled in some respects for use in the Audi Q5 hybrid. The drive of the ancillary units has been dropped, and the crankshaft bearing and fine tuning of the turbocharger have been adapted to the specific demands. A secondary air system at the cylinder head makes sure that the exhaust gas treatment cuts in particularly fast. Integrated in the engine control unit, the so-called hybrid manager controls the efficient change and smooth transitions between the operating modes, and was fully developed by Audi alone.

A largely modified eight-speed tiptronic serves the power transmission without the aid of a torque converter. Its place is taken by the disk-shaped electric motor, combined with the multi-plate clutch operating in an oil bath - it couples and decouples the electric motor and the TFSI. The innovative decoupler operates with high precision, smoothly and quickly in any situation.

The highly comfortable and fast-shifting hybrid gear unit contributes significantly to the efficiency of the Audi Q5 hybrid - its eight gears are widely spaced. When the 2.0 TFSI is turned off, an electric pump maintains the oil pressure in the hydraulic system to safeguard the convenient start-stop feature.

The Power Electronics and the Electric Motor
The power electronics, connected to the battery and the electric motor by high-voltage cabling, is located in the plenum chamber of the engine compartment. In the form of a so-called pulse-controlled inverter, the power electronics serves as a controller between the battery, which outputs direct current, and the electric motor that operates on alternating current.

Innovative technologies keep the volume and weight of the power electronics low, with cooling provided by a separate low-temperature water-filled circuit. The component includes a DC/DC converter that couples the electric consumers in the 12 V electrical system with the high-voltage network.

A so-called permanently excited synchronous machine serves as an electric motor, as a starter and - during deceleration - as a generator. It outputs up to 33 kW (45 hp) of power and 211 Nm (155.63 lb-ft). The electric motor is integrated in the cooling circuit of the engine.

The Battery
A lithium-ion battery system, weighing merely 38 kg (83.78 lb), serves as the energy store for the electric motor of the Audi Q5 hybrid quattro. The compact unit with its 26 liter (6.87 US gallon) capacity is positioned in a crash-safe area under the loading floor, with hardly any detriment to the luggage compartment. The battery consists of 72 cells; at 266 volts its nominal energy is 1.3 kWh and its output 39 kW.

The lithium-ion battery is cooled by air in two ways, depending on the requirement. At low-temperature load, it draws temperate air from the vehicle interior by way of a fan. If its temperature exceeds a certain limit, a separate refrigerant circuit is activated. It is coupled to the main climate control system of the vehicle and uses a separate evaporator.

This heavy-duty active cooling system distinguishes the Audi Q5 hybrid quattro from many other hybrid vehicles, and makes a key contribution to the high electrical availability of the hybrid system.

The Operating Modes
With its parallel hybrid system the Audi Q5 hybrid quattro can travel in five different operating modes. Driving with the combustion engine alone, with the electric drive alone or in hybrid mode is possible, as are recuperation and boosting.

At a standstill, e.g. before starting or at a traffic light, both drive sources are deactivated. In this convenient start-stop mode the climate control system remains active. Once the driver releases the brake, the Audi Q5 hybrid quattro starts rolling. It can be driven up to 100 km/h (62.14 mph) under electric power - with almost no noise or local emissions. At a constant 60 km/h the possible range is three kilometers (1.86 miles) - this high electrical share of the driving suffices for most residential areas and many urban centers.

The driver can change between three programs using a button on the center console or a selector lever. The EV characteristic map gives priority to the electric drive in the city, the D mode controls both motors for optimal consumption, and the S mode as well as the touch control gate of the tiptronic are designed for a sporty driving style.

When the driver accelerates sharply, the combustion engine serves as a power source for the drive. The electric motor is then actuated by the operating strategy in order to achieve optimal efficiency and consumption. In quick acceleration, or "boosting," the electric motor operates together with the TFSI; at full throttle in the S mode the full system output is briefly available. The hybrid drive then supplies the propulsion power of a large naturally aspirated engine, but with far more efficiency.

When the driver releases the accelerator, the electric motor acts as a generator and recovers energy. In most situations the TFSI is then decoupled from the drive system so as not to cause any loss from towing. The electricity recovered by the electric motor here and in braking is buffered in the lithium-ion battery. If the driver brakes only slightly, the electric motor performs the deceleration itself; in more forceful braking the hydraulic braking system is simultaneously activated.

Operation
The Audi Q5 hybrid comes with a new display concept, rendering the individual driving states of the hybrid drive clear-cut and tangible. Instead of the tachometer, the needle of the power meter in the dash panel insert indicates the total output of the system on a scale of 0 to 100 per cent. A second scale is divided into colored segments - their green and orange-colored sections show at a glance how the Q5 hybrid quattro is currently traveling - with a greater share of electrical power or combustion engine power. An additional instrument displays the charge level of the battery.

At the same time, the display of the driver information system and the large monitor of the MMI Navigation plus show the operating states and power flows in the hybrid system in elegant graphics with a three-dimensional effect. The MMI screen also displays differentiated consumption and recuperation statistics in easily understandable bar graphs.

The MMI Navigation plus is standard on the Audi Q5 hybrid quattro, and comes in the latest stage of evolution. The storage capacity of the hard drive is 60 GB, the menus can be selected via a state-of-the-art wizard, and the album tracks are displayed using the cover artwork. An external device such as a cell phone or player can be connected via Bluetooth, and the voice input understands town and street names in a single command. The resonant Audi sound system is also standard.

The quattro Drive and the Running Gear
The permanent four-wheel drive applies the power of both power units safely to the road in any situation. In the normal condition the sporty drive is emphasized at the rear; if need be, it transmits most of the power to the axle with the better traction. The sophisticated running gear includes many aluminum components for reduced weight. The Audi Q5 hybrid quattro may pull trailer loads of up to 2000 kg (4409 lb).

An electro-mechanical unit serves as the steering system, with a small electric motor generating the power. The system operates at high efficiency, since it need not consume any energy in straight-ahead driving. The brake servo is additionally supplied by an electric vacuum pump. A complex rule-based strategy adapts the braking to the conditions of electric driving and energy recuperation.

The Exterior
The Audi Q5 hybrid quattro is distinguished by visual features on the outside. The tailgate, the fenders and the aluminum sill panel strips bear the hybrid lettering. The radiator grill is glossy black, and the tailpipes chrome-trimmed. Polar Silver, metallic is available for the exclusive paintwork.

The 19 inch cast aluminum wheels were specially designed for the hybrid - their ten spokes resemble turbine blades. The tires are size 235/55. On request Audi supplies other wheels with 19 and 20 inch diagonals, with an S-line bumper available from quattro GmbH.

The body is unusually light in weight; the tailgate and the engine hood are aluminum. The rigid body shell incorporates hot-stamped steel at numerous places, combining low weight with very high strength.

Despite the generous level of standard equipment, the Q5 hybrid quattro with its curb weight of less than 2000 kg (4409 lb) is the lightest hybrid SUV on the world market. All its hybrid components add less than 130 kg (286.60 lb) extra weight.

The Equipment
The climate control system of the Audi Q5 hybrid was adapted to the requirements of electric driving. The compressor of the air conditioning has a high-voltage based electric drive; demand-controlled for high efficiency, the compressor ensures AC operation even when the combustion engine is shut down. An electric auxiliary heater supports the interior heating.

The Audi Q5 hybrid quattro offers almost the same equipment as its successful sister models - the model series leads the European market in the mid-sized SUV segment. The options also include sophisticated driver assistance systems. A new feature is connection to the internet via the optional Bluetooth car phone online. A UMTS model sets up the connection to special services from Google and the World Wide Web, bringing the latest news and weather information into the vehicle.

The driver can plan his or her travel route at home, save the information in an area of the internet site www.audi.com and from there download the data into the navigation system via UMTS at the start of the trip. Through the fast connection the hybrid SUV also downloads three-dimensional satellite images and aerial photos from Google Earth. They appear as bird's eye views on the monitor; the computer draws in the roads.

Another high-end feature is the WLAN hotspot, allowing connection to the internet via up to eight terminal devices. Communication occurs via the roof antenna, the connection is very stable and the reception quality excellent. Thanks to a special modulation process, UMTS data transfer occurs at speeds up to 7.2 MB per second. Encryption follows the WPA 2 standard - a very secure method.

The use of the WLAN hotspots is as easy as can be - the driver need merely insert a data-capable SIM card. At the same time the driver can pair a cell phone with the system via Bluetooth, if the phone has the SIM Access Profile. The existing mobile phone contract with a data option suffices in most cases with the result that no additional charges or separate contracts are necessary.

The Audi Q5 hybrid quattro will arrive at dealerships during 2011.

2012 Audi Q5 Hybrid Quattro Review

Power as a V6, the fuel consumption and four-cylinder TDI - the quattro Audi Q5 hybrid, which should reach dealers by the end of the year is the first mass produced hybrid model of Audi, which makes the use of two drive systems.

During the development process, Audi covered a significant portion of the raceways. The market for hybrid performance SUV can drive up to 100 km / h (62.14 mph) in electricity and covers about five miles without any problems at the local level at a speed of 60 km / h (37.28 mph). With the strong light lithium-ion batteries and many other solutions, the quattro Audi Q5 hybrid represents the state of the art.

Performance

The 2.0 TFSI engine and electric motor in the hybrid Audi Q5 is mounted directly behind the other as a parallel hybrid system - a concept straight with impressive efficiency. Together, they have a system output of 180 kW (245 hp) and torque of 480 Nm system (£ 354.03 ft). Audi Q5 Hybrid sprints from 0 to 100 km / h (62.14 mph) in 7.1 seconds, while the intermediate sprint from 80 to 120 km / h (49.71 to 74.56 mph) is achieved in fifth gear of 5.9 seconds. Propulsion ends no less than 222 km / h (137.94 mph).

In the normal cycle, the Audi Q5 Hybrid consumes 6.9 liters of fuel per 100 km (33.60 U.S. mpg) - which corresponds to the level of CO2 emissions of 159 g / km (257.50 g / km). Tank of 75 liters (19.81 gallons) can be comparable to the impressive range of the TDI.

Training

The 2.0 TFSI Audi Q5 Hybrid is a displacement of 1984 cc. Its output is 155 kW (211 hp) and torque of 350 Nm (258.15 pounds-ft) available constantly from 1500 to 4200 rpm. four-cylinder petrol unit combines direct injection with turbocharging. Audi valve lift system (AVS), in addition to more power, torque and efficiency of connecting a cylinder exhaust valves in two stages depending on load and rpm.

The 2.0 TFSI has been redesigned in some respects, for use in the hybrid Audi Q5. Powered by additional units have been lost, and the crankshaft bearing and fine tuning of the turbocharger has been adapted to specific needs. A secondary air system on the yoke so that reductions in exhaust gas treatment particularly fast. Integrated into the engine control unit controls the hybrid leader, concrete changes and smooth transitions between operating modes.

Much tiptronic is changed to eight reports of power transmission without using a torque converter. His place is taken by the electric motor in a disc combined with a multi-disc clutch in oil bath, as a couple and disconnect the electric motor and TFSI. Decoupling innovative works accurately and smoothly in any situation.

The gear extremely comfortable and fast evolving hybrid contributes significantly to the effectiveness of the hybrid Audi Q5 - the eight machines are far away. When the 2.0 TFSI is disabled, an electric pump maintains oil pressure in the hydraulic system for the convenient start-stop.

Power electronics and electric motors

The radiator tank in the engine compartment houses the power electronics. The UPS allegedly controlled by the pulse controller is used between the battery, which came out in DC, and the electric motor running on AC power. Innovative technologies to maintain the volume and weight of low power electronics, with cooling provided by a separate circuit filled with water at low temperature. The component includes a DC / DC converter that couples electrical consumer electrical system 12 V high voltage.

If the temperature exceeds a certain limit is a separate cooling circuit activated. It is connected to the main climate control system of the vehicle and uses a separate evaporator. This mechanism of active cooling is effective in a major electric hybrid system for high availability and enables the quattro Audi Q5 Hybrid is distinguished from many other hybrid cars.

Operating Modes

Audi Q5 hybrid four can run five operating modes. Drive a combustion engine alone, the use of electricity alone or in hybrid mode, it is possible, as well as recovery and improvement. Stalled - before or at the traffic lights, for example - is to guide the use of sources. Here's how "comfort" start-stop, the air conditioner is turned on. When the driver releases the brake, Four Q5 hybrid will start coasting. You can drive up to 100 km / h (62.14 mph), the electricity - almost without any noise or local emissions. At a constant speed of 60 km / h (37.28 km / h), is a series of 3 km - sufficient for many residential areas and city centers.

The driver can switch between the three programs using a button on the console shifter or. EV short feature priority to the electric car in town, the D mode controls both engines to the optimal consumption and the S mode and touch the door tiptronic is designed for sporty driving style.

If the driver accelerates rapidly, the internal combustion engine takes over and provides traction. Now the main task electric motor is to run the high-consumers and keep the battery charged. In hard acceleration, or "promote", electric motor drives with TFSI, with full power mode S card output system available. In such cases, provide a hybrid large naturally aspirated engine, but with greater efficiency.

When the driver releases the accelerator, the electric motor acts as a generator and battery power is restored. In most situations, the TFSI is then disconnected from the system unit to cause no accumulated losses. The power recovered by the electric motor and braking here protects the lithium ion batteries. If the driver brakes a bit, the electric motor itself provides the strongest deceleration brake hydraulic brake system is activated at the same time.

Use of the vehicle

The Audi Q5 Hybrid is a novel display concept, which can be every mode of behavior of the hybrid car lived. The tachometer has been replaced on the scoreboard with a "power" with a needle that indicates the total output of the system on a scale of 0 to 100. A second scale is divided into colored segments, greens and orange segments clearly indicate that the hybrid drive system Q5 quattro is currently using.

2011 Audi TT RS Review

Audi is once again producing a five-cylinder engine - and a very special. Arriving at retailers this summer, Audi TT RS is a turbocharged 2.5-liter gasoline direct injection and produces 250 kW (340 hp) and 450 Nm (331.90 lb-ft) of torque. The five-cylinder engine burn gives the Audi TT RS for making outstanding achievements. As part of quattro permanent four-wheel drive and a high-performance chassis, the engine makes the Audi TT RS compact car premium sport - available in coupe and roadster.

sports five-cylinder petrol engines have a long history of Audi. The most famous is probably the 2.1 liter turbocharged engine in the Audi quattro. The first version, launched in 1980, offered an impressive 147 kW (200 hp). Audi Sport Quattro and 1984, directly inspired by motor sport, has delivered an enormous 225 kilowatts (306 hp). For 25 years, turbo and quattro was a dynamic formula for success.

Audi has chosen to use this recipe. Designed from the ground, five-cylinder turbo engine combines direct fuel injection to raise the FSI Audi TT RS high-performance sports car. TFSI produces 250 kW (340 hp), the transition from 2480 cc (151.34 cu): a special power of 100.8 kW (137.1 hp) per liter.

Power to weight ratio is excellent. In the case of the Coupé, which weighs just 1,450 kilograms (3,196.70 pounds), power to weight ratio is only 4.3 kg / hp. Audi TT RS Roadster weighs 1,510 kilograms (3,328.98 pounds) and power to weight ratio 4.4 kg / hp - thanks to the ultra-lightweight aluminum frame and largely built around the principles of Audi Space Frame.

The Audi TT RS coupe rockets from 0 to 100 km / h (0 to 62.14 km / h) in 4.6 seconds, the Audi TT RS Roadster needs only a tenth of a second. The speed limit of 250 kmh (155.34 mph) is the official figure of the two versions as an option, Audi can increase to 280 km / h (173.98 mph).

Almost more impressive is the attraction aggressive. Torque of 450 Nm (331.90 Nm) is available between 1600 and 5300 rpm. In addition, the Audi TT RS passes without the slightest effort.

And weighing just 183 kilograms (403.45 pounds), also set a record. The casing is made of vermicular graphite cast. This high tech material attaches the greatest strength with low weight, was also used for more Audi TDI engines. Perfectly located reinforcements improve the capacity for load. Light cylinder head, pistons and connecting rods are light weight and high strength.

The ultra-powerful engine with five cylinders is extremely fuel efficient, requiring an average of only 9.2 l/100 km [25.57 mpg] in terms Coupé (cabriolet: 9.5 l/100 km [24, 76 mpg]). switchable flaps in the intake manifold air mixture entering a configuration calculated. Injected with a pressure up to 120 bar common rail system, the gasoline intense vortices in the combustion chamber - which in turn cools the walls. This then facilitates a 10.0:1 compression ratio of which is very high for a turbo engine. The two adjustable camshafts, driven by chains, also to improve the charging efficiency of air-fuel mixture.

The turbocharger generates high as 1.2 bar boost pressure. The intercooler, fully supplied with air at the bottom of the inner grid, reducing the temperature of air compressed by over 80 percent at full load.

When the standard Audi TT RS Sport driver presses the button on the center tunnel, the flap installed on the left exhaust pipe exhaust system makes the noise even stronger and more powerful at the same time, increasing engine responsiveness. The optional sport exhaust system is available in matte black exhaust emissions and sound flip.

For the purists, the kinematics.

The Audi TT RS is the classic sports car family first Audi RS. Like the Audi RS4 Audi RS6 and Audi TT RS was developed by quattro GmbH so pure, no holds barred driving machine. A new six-speed manual transmission transmits the enormous power of the engine, and allows easy operation and precise thanks to a display shifter specially designed tours especially short passage. defining the transmission characteristics are a high rate of return and sports tight space ratios.

The Audi TT RS has quattro permanent all standard equipment. His heart is in the rear, an electronic control, hydraulic clutch blinds. If the situation requires it, the clutch directs most of the input torque of the front wheels to the rear wheels.

Within milliseconds, a powerful electric pump with battery weighs together through a hydraulic clutch. Four added power line falls at a constant speed, before the 'common propeller shaft and a compact rear axle differential - both are heavy elements.

Subsidies quattro, Audi TT RS outstanding fascinating dynamics and excellent stability. Dissolution of rural areas or a few laps on a circuit to allow top management to shine.

2011 Audi A8 Test Drive Reviews

Audi A8 Test Drive.From a touch-based interface that allows drivers to enter queries by simply drawing characters to an all-new eight-speed transmission and some of the highest-quality interior materials we've seen, the car is a monumental achievement for Audi.

Throw in the on-the-fly throttle mapping (via Audi's Drive Select setup in the multimedia interface), and the eight-pot seems like the perfect choice for Audi's flagship leviathan.

Audi says it has managed to increase fuel economy by up to 15 percent, thanks to the slimmer beltline and remarkable gearbox. The EPA hasn't churned out final figures on the Audi A8 yet, but if Audi is to be believed, we should be looking at somewhere around 18 mpg city and 26 mpg highway.

The material quality inside the new Audi A8 is a benchmark for Audi, for the first time besting both BMW and Mercedes-Benz by a comfortable margin. There's entirely new ambient LED interior lighting, found in soft strips reminiscent of neon in carefully chosen places. The navigation hooks up with Google, and to input an address, you simply write out the address--with your finger--on a console-mounted pad. The biggest surprise here is that the system actually works.

The full-size luxury-car segment is a ship constantly steered by a new captain. The BMW 7-series recently pulled off this feat, topping the previous gold standard, the Mercedes-Benz S550, in a comparison test. One Engine Now, Others Coming
Audi says the Audi A8 returns 13-percent-better fuel economy than does its predecessor, which translates roughly to 18 mpg in the city and 25 mpg on the highway for the new car.

Have no fear, power brokers: There will be other engines available in the coming years. The diesel feels peppy thanks, to the smooth-shifting eight-speed automatic transmission, which is perfectly calibrated to keep the engine in the juicy part of the torque plateau. Unmistakably an Audi, the A8 Is Light on Its Feet

Wheel sizes range from 17 inches to 20.
That demeanor comes in part from the fitment of the high-tech bits that are optional on lesser models as part of Audi “drive select” packages. Standard on the Audi A8 are adjustable shocks, variable-rate air springs, variable-ratio steering, and most notably, the torque-vectoring rear differential found in the S4 and S5. A “more dynamic” adjustable air suspension is part of a Sport package on the current car, but given the new car’s standard chassis hardware, we expect that if such a package were to be offered, it would encompass only wheels and aesthetic tweaks.)
The trick diff helps curb the effects of that longtime bane of Audi dynamics, weight distribution. Audi engines have traditionally been bolted well ahead of the front axle, a front-heavy setup that contributes to predominant, if predictable, understeer. Like the latest 7-series, the Audi A8 drives smaller than its length (202.2 inches) suggests, and the variable-rate steering transmits a good amount of information from the tires. Mobile Office Redefined

In sales, Audi's flagship A8 has lagged a distant 3rd to its Teutonic competitors, the BMW 7 Series and Mercedes-Benz S-Class. True to Audi's subtle style, the 2011 Audi A8 isn't a radical departure from the previous design, with no bulging Bangle butt or swooping Benz roof line.

Performance
We drove the 2011 Audi A8 4.2 FSI Quattro at a press event near Malaga, Spain, when the Costa del Sol defied its description on a day of heavy rain. Engine torque is rear-biased, with the all-wheel-drive system directing 60 percent of power to the rear wheels and 40 percent to the front. A non-intrusive stability control system helps keep all four wheels planted. Audi's Drive Select feature has four settings -- Comfort, Auto, Dynamic and Individual -- for varying the throttle response, shift points, steering feel and suspension stiffness.
We left the tranny in auto-sport mode for highway cruising and spent the majority of our twisty mountain-road time working the paddle shifters.

Comfort
In the 2011 Audi A8 Sedan, high performance doesn't come at the expense of comfort. The rear-seating area is generous, with ample leg- and headroom. The optional rear entertainment system includes a separate set of Audi's Multi Media Interface (MMI) controls that allow access to any entertainment option.

Function
If there's one area in which Audi has an advantage over its Teutonic competitors, it's with the MMI controller. Using a finger, drivers can trace letters on the touchpad to input navigation system destinations. Like other nav systems, it loads logical choices as each character is entered, but with the 2011 Audi A8's system you don't have to hunt and peck on a traditional touchscreen or dial in a destination using a rotary controller.

B&O's trademark Acoustic Lens tweeters rise out of the dash when the system is turned on and recess when it's switched off.
The designers went a little wilder (by Audi's previously Spartan standards) in the interior, especially compared to the previous austere treatment.
Our 4.2 FSI test car's interior came laden with rich wood, sleek aluminum and soft leather accents. The 2011 Audi A8 offers best-in-class technology and competitive performance.

Audi matches the Mini Cooper S pretty much point for point with the engines sharing a similar output and the cars having plenty of kit to help the medicine go down. TECHNOLOGY
The seven-speed is the only transmission on A1 Sport and offers D for lazy-bones drivers and paddle shift for the sporty punters.

Works a treat giving the diminutive A1 Sport decent acceleration and strident roll-on performance at all speeds.

The body/chassis features generous use of high strength steel for added rigidity.
Electronics feature heavily in controlling the A1 Sport with sports stability control and an electronic limited slip differential that has a similar effect as torque vectoring (using the brakes/throttle to help steer the car)

DESIGN
The seats themselves are more sports oriented with deeper side bolsters and firmer padding.
There's plenty of safety gear too including six air bags, rear park assist and a five star crash rating.

DRIVING
What fun.
Needless to say the A1 Sport acquitted itself admirably whipping through the safety cones like a scalpel, blasting over the 400 metre drag race strip and behaving like a racing kart on the street circuit. VERDICT

We like the A1 Sport for its spirit.
The Audi A1 is determined by the VW Polo platform, a design because the cheapo edition from the short-lived Audi 50. Audi will even paint the roof pillars, which stretch from front to rear in a single easy arc, in a very contrasting shade for additional awesomeness.

The 2011 Audi A1 provides an option of four turbocharged four-bangers: two diesel and two gasoline engines. Petrolheads obtain a selection of the 1.2-liter, eight-valve engine making 85 hp as well as a 1.4-liter 16-valver turning out 122 hp. The sensation of control is improved from the 2011 Audi A1’s outstanding chassis setup. It is Audi’s model with the Volkswagen XDS program, and it arrives on each 2011 Audi A1, not only on top-of-the-line versions, like at VW.

Once you discover how the site behaves TFSI high speeds, running at a normal pace will not seem at all attractive. Sweet sensations will be amplified by a precise transmission with short halves, which will ask you to stick your hand grip and switch to demote sick and obsessive closer every turn. Merriment that demonstrates little German and perfectly reflects the value of acceleration. For child occupant protection received an A1 rating satisfactory, but not the same thing happened in Chapter pedestrian protection, which endangered the life hood dummy. It comes with standard ESP, electronic differential lock , EDS, ASR, EBV and, of course, ABS.

Engineers have installed automatic air conditioning, power windows, audio quality, light and rain sensors and steering wheel. To demonstrate the premium, but the Germans raise a multimedia system with Audi fans already familiar with quality materials, auxiliary audio connections with a navigation system and a mobile phone connection. Mini segment having a head which passes back and rely more on emotional impact, the Audi was forced to risk everything to design.

2012 Audi R8 GT Spyder

Audi has unveiled the R8 GT Spyder.

Sprinting from 0-62mph in a Lambo-beating 3.8sec before hitting a 197mph top speed, the R8 GT Spyder has had 85kg stripped from the R8 Spyder’s aluminium frame thanks to carbon-fibre skin and seats. The mid-engined supercar weighs 1640kg, thumps out 552bhp and 398lb ft from its 5.2-litre, direct-injection V10 engine and is based around an aluminium space-frame chassis weighing just 214kg.

Setting the car apart from its standard sibling is an updated aerodynamics package aimed at increasing high-speed downforce. Included is a dual-lip front splitter, a redesigned diffuser element, round chrome exhaust pipes and darkened taillight lenses.

An electrically operated fabric roof opens in 20 seconds and at speeds up to 30 mph, stowing behind the cabin underneath a carbon-fiber cover. A deep well beneath the hood at the front provides space for luggage.

Just 333 units will be made with European pricing set at 207,800 Euro. No U.S. pricing has been released, but with the coupe set at $198,000 look for a number just shy of $210,000.





Press Release

Aggressive power and Audi ultra - the Audi R8 GT Spyder

• Open limited-production, top-of-the-line version of the high-performance sports car

• 85 kilograms lighter, body parts in carbon

• V10 FSI with 412 kW (560 hp), 0 - 100 km/h in 3.8 seconds

Even lighter, even more powerful, even more captivating: The Audi R8 GT Spyder delivers breathtaking performance. The open-top flagship version of the high-performance sports car develops 412 kW (560 hp) and - thanks to Audi ultra - has trimmed a full 85 kilograms (187.39 lb) from an already low weight. The R8 GT Spyder accelerates from zero to 100 km/h (62.14 mph) in 3.8 seconds and reaches a top speed of 317 km/h (196.97 mph).

One year ago, Audi unveiled the R8 GT in coupe form as the new flagship model of the R8 model line. It wasn't long before all 333 units in the limited series were sold out. Now the open-top version of the high-performance sports car is being launched, with production again capped at 333 units. Each car sports a tag with its individual number on the gear lever knob.

The Audi ultra lightweight technology is the key to the R8 GT Spyder's weight of just 1,640 kilograms (3,615.58 lb). That's 85 kilograms (187.39 lb) less than its technical basis, the R8 Spyder 5.2 FSI quattro. The Audi Space Frame (ASF) body, consisting of cast nodes, extruded sections and aluminum panels, accounts for just 214 kilograms (471.79 lb) of the total weight. The body is assembled predominantly by hand in the R8 workshop at the Neckarsulm plant. Final assembly of the car takes place in the same way.

The engine frame is made of ultra-light magnesium; the long cover over the soft-top compartment and the large side panels at the rear are made of carbon fiber-reinforced polymer (CFRP). CFRP is also used for the modified front spoiler, the fixed rear spoiler and the new rear bumper. Together, these components provide a weight saving of 5.5 kilograms (12.13 lb).

Visual modifications accentuate the styling of the R8 GT Spyder. These include add-on parts in contrasting titanium gray, a front splitter with a dual lip, flics at the sides of the front bumper, red GT badges, round exhaust tailpipes, an enlarged diffuser and dark LED tail lights in a clear-glass design. Audi offers an optional windshield frame in matt CFRP.

Audi engineers also trimmed weight from the technical components in the area of the transmission, wheels and brakes. In the interior, the bucket seats alone, with their chassis of glass fiber-reinforced polymer (GFRP), saved 31.5 kilograms (69.45 lb) of weight.

In classic Audi fashion, the R8 GT Spyder features a lightweight fabric soft top that is extremely quiet and fully suitable for highway cruising. Its electrohydraulic drive brings it up or down in 19 seconds, even at speeds up to 50 km/h (31.07 mph). The extendible glass rear window is nestled in the bulkhead, separate from the soft top. Integrated in the bulkhead is a rollover protection system comprising two pretensioned plates.

Prodigious power: the drivetrain
The performance offered by the new top-of-the-line model in the R8 family is formidable. The 5.2-liter V10 with an aluminum crankcase draws its fuel from an FSI direct injection system. Dry-sump lubrication ensures a reliable supply of oil even under maximum lateral or straight-line acceleration.

With its modified electronic management, the long-stroke engine produces 540 Nm (398.28 lb-ft) of torque at 6,500 rpm, and its peak output is 412 kW (560 hp). Each unit of horsepower has only 2.93 kilograms (6.46 lb) to move.

The R8 GT Spyder catapults from zero to 100 km/h (62.14 mph) in 3.8 seconds and reaches a top speed of 317 km/h (196.97 mph). In every situation, the engine impresses with its thrust and bite - and that unmistakable sound of an Audi ten-cylinder.

The R8 GT Spyder comes standard with an automated six-speed R tronic transmission with two fully automatic modes. In the additional manual mode, the driver can shift gears using the paddles on the steering wheel or by flicking the joystick. At high load and revs, gear changes take only one-tenth of a second. The launch control program manages the starting sprint with high engine speed and precision-control of the tire slip.

The quattro permanent all-wheel drive has a strong rear-wheel bias, granted by the axle load distribution. If the situation calls for it, the system sends additional torque to the front axle. In tandem with the limited slip differential at the rear, it provides an added measure of traction, stability and cornering speed, giving it a strong lead over the rear-wheel-drive competition.

The suspension, too, is unrivaled in its performance. Aluminum double wishbones locate the wheels, and the rack-and-pinion power steering provides intimate contact with the road. Taut tuning lowers the body by approximately 10 millimeters (0.39 in). The open high-performance sports car has 19-inch wheels, with 235/35 tires up front and 295/30 tires at the rear. The large, lightweight carbon-fiber ceramic brake discs decelerate the car with supreme ease. The ESP stabilization program has a sport mode and can also be deactivated entirely.

Pure comfort: the interior and equipment
Great attention to detail is evident in the materials and workmanship inside the car. The salient aspect of the controls is their logically structured design. The open two-seater offers a roomy interior, and its front end can accommodate up to 100 liters (3.53 cu. ft) of cargo. The rear bulkhead houses three storage compartments.

The interior is black and can be adorned with stitching in a choice of titanium gray or crimson for added refinement. Alcantara upholstery comes standard - on the sport steering wheel and windshield frame, too.

Audi also offers leather in Fine Nappa quality. Numerous details - including white dials and R8 GT logos - provide classy accents. The distinctive R8 "monoposto," a large arch encircling the driver's cockpit, is made of matt CFRP.

Audi ultra requires no sacrifice on the part of R8 GT Spyder owners. The standard equipment includes LED headlights, LED tail lights, an automatic air conditioning system, the navigation system plus, an alarm system and the driver information system with a built-in laptimer.

Audi also offers a sophisticated sound system from Bang & Olufsen and a Bluetooth interface including a seatbelt microphone for carrying on a phone conversation conveniently. Options specific to the R8 GT include bucket seats with a carbon-fiber composite chassis, matt CFRP applications and embroidered logos on the seat upholstery.

The R8 GT Spyder will have a base price in Germany of 207,800 euros.
