Audi R8 V10 5.2 FSI quattro, 2010

 

 

 

 Audi R8 V10 5.2 FSI quattro is the next variant of its top-of-the-line model. With the Audi R8, the brand has established itself at the forefront of high-end sports cars from the very start - and now comes the Audi R8 V10. Its 5.2-liter, ten-cylinder engine churns out 386 kW (525 hp) and 530 Nm (390.91 lb-ft) of torque, which makes for breathtaking performance. With superior Audi technologies such as quattro all-wheel drive, the lightweight aluminum body, the innovative all-LED headlights, and its striking design, the Audi R8 V10 takes pole position against the competition.

The Audi R8 V10 is the result of cumulative know-how from Audi's string of Le Mans victories. Its naturally aspirated engine combines racing technology such as dry sump lubrication with FSI gasoline direct injection. The ten-cylinder design is the perfect synthesis for impressive top performance, mighty pulling power, and low weight. Starting in 2009, this engine will also prove its potential on the world's racetracks - in the new Audi R8 GT3 racing car Audi is developing for customer teams in conformance with the GT3 rules.

The specific power output is 100.9 hp per liter of displacement - and each hp has to propel only 3.09 kilograms (6.91 lb) of weight, because the Audi R8 V10 in the version with the six-speed manual gearshift weighs only 1,620 kilograms (3571 lb). The engine accounts for 258 of these kilograms (569 lb) - that's only 31 kilos (68 lb) more than the V8.

The Audi R8 V10 5.2 FSI quattro rockets from zero to 100 km/h (62.14 mph) in 3.9 seconds. In the version with the sequentially shifting R tronic it reaches 200 km/h (124.27 mph) in another 8.1 seconds. Even then its propulsive power hardly lessens: it's sufficient to reach a top speed of 316 km/h (196.35 mph). The immense force, the spontaneity and the thrust of the acceleration, plus the sound of the engine - all these impressions coalesce into a breathtaking sports car experience. The V10 plays a concert with growling bass tones and powerful high notes, which grows into a grandiose fortissimo as the engine revs up. This sonorous acceleration doesn't reach its limit until 8,700 rpm.

The 5.2-liter powerplant uses direct injection according to the FSI principle developed by Audi. A common rail system injects the fuel into the combustion chambers with up to 120 bar of pressure. Direct injection reduces the susceptibility to knocking and provides a certain amount of cooling through the evaporation of the fuel, which in turn supports a high compression ratio of 12.5:1. This in turn contributes to superior performance and improves fuel economy. The Audi R8 V10 with R tronic gets by on an average of 13.7 liters per 100 km (17.17 US mpg).

The Audi R8 V10 5.2 FSI quattro has a six-speed transmission. A precise and smooth-shifting manual transmission comes as standard equipment. The sequential R tronic is available as an option. The high-tech gearshift conveys an authentic racing feel - with the rocker switches at the steering wheel and the short shifting times of usually less than one-tenth of a second. When the driver actuates the Launch Control program by pressing a button, the Audi R8 V10 takes off in a vehement quick-start with electronically controlled tire slip - both with the R tronic and with the manual transmission.

44 to 56 percent - the ideal axle load distribution
The Audi R8 chassis offers both dynamic performance and astonishing levels of comfort on long distances. This high-performance sports car from Audi eagerly responds to any steering action with instant ease, achieves lateral acceleration of up to 1.2 g, and handles any situation with superb driving safety. Its mid-engine design provides an ideal axle load distribution of 44 to 56 percent.

Audi quattro Concept, 2010

 

 

 

In celebration of the 30th anniversary of the debut of the quattro, Audi is presenting a show car at the 2010 Paris Motor Show that moves a futuristic interpretation of this concept into the fast lane: the Audi quattro Concept, a thoroughbred driving machine with 300 kW (408 hp), five-cylinder turbocharged engine, a lightweight body and - of course - the latest generation of quattro permanent all-wheel drive.

The Audi quattro Concept uses the latest evolutionary stage of the quattro permanent all-wheel drive system to deliver its power to the road. The key innovation, the crown-gear center differential, is compact, lightweight, and can vary the distribution of power between the front and rear axles over a broad range, enabling the quattro drive system to react within milliseconds to coax the maximum of fun and safety out of every last bit of torque.

Design
Brawny, compact, powerful: The appearance of the Audi quattro Concept makes no secret of its potential. Although the genes of the elegant Audi A5 and RS5 Coupés are impossible to overlook, the appearance of the show car is far more aggressive and extroverted. Even the obvious differences between the base model and the evolution are more dramatic than between the Ur-quattro and the Sport quattro in 1984.

In contrast to Sport quattro, the Audi designers also shortened the rear overhang by a total of 200 millimeters (7.87 in) to maintain the harmony of the basic proportions. Roof height was reduced by 40 millimeters (1.57 in) for this same reason.

With its exterior dimensions (length x width x height) of 4.28 m (14.04 ft) x 1.86 m (6.10 ft) x 1.33 m (4.36 ft) and wheelbase of 2.60 m (8.53 ft), the Audi quattro Concept fits neatly into the sports car segment.

The wheel wells in the arched fenders are prominently flared - another quote from the design language of the Sport quattro. The same applies to the distinctive air outlet on the right side of the hood, which allows the five-cylinder engine to breathe more freely.

A significant feature of the front end is the stark single-frame grille. The elimination of the chrome frame lends it a functional and technical character. Large, upright air intakes at the corners of the bumper underscore the performance of the power plant.

The top of the grille merges into the flat strips of the headlight modules with their clear glass covers. All light units use ultra-efficient LED technology. The LED elements change their appearance between a horizontal and a vertical arrangement and thus change the character of the front end of the vehicle depending on the lighting function activated.

Interior
The interior of the coupé is reduced and clean. The dashboard is very slender and seems to float over the separate center console. Shortening the wheelbase meant losing the rear seat of the RS5 on which it is based. In its place is a shelf for helmets or luggage. Awaiting the two occupants are filigree bucket seats, during whose development the issue of lightweight design played a central role. They weigh only 18 kilograms (39.68 lb) each - a weight advantage of roughly 40 percent versus a conventional production seat. The seats are equipped with either three- or four-point belts.

Body
A true sports car is always a light car, and the Audi quattro Concept shines in this discipline as well.

The key factors are the choice of material and the design. Rather than mostly steel as in the Audi RS5, the body comprises lightweight aluminum components assembled using Audi Space Frame ASF technology. Extruded sections, die-castings and aluminum sheets form an impact-resistant structure of exceptional strength. The hood and the rear hatch with its integrated, moveable spoiler, plus the bumpers and numerous aerodynamic components are made of even lighter and high-strength carbon.

The body-in-white of the coupé weighs just 159 kilograms (350.53 lb); it would be nearly 50 percent heavier if made entirely of steel.

The low weight of the superstructure leads to significant secondary effects regarding size and weight in other components of the vehicle, such as the transmission, the chassis and the brake system. All together the Audi quattro Concept tips the scales at just 1,300 kilograms (2,866.01 lb), which is roughly 200 kilograms (440.92 lb) lighter than even the comparably sized Audi TT RS, whose body is also largely made of aluminum.

The allure of the five-cylinder engine
High-performance five-cylinder gasoline engines enjoy a long tradition at Audi, powering cars like the Ur-quattro to the head of the pack. Audi resurrected this line back to life in 2009 with the 340 hp, turbocharged FSI engine in the TT RS. The further developed engine in the Audi quattro Concept extracts even more potential from this new, state-of-the-art five-cylinder foundation.

Inside the new center differential are two rotating crown gears that owe their name to the crown-like design of their teeth. The front crown gear drives the output shaft to the front differential, the rear crown gear the propshaft to the rear axle. The connection here is provided by an ambitious construction. The new drivetrain design is roughly 3 kilograms (6.61 lb) lighter than the previous one.

The crown gears mesh with four rotatable pinion gears. They are arranged at right angles to each other and are driven by the differential's housing, i.e. by the transmission output shaft.

Like on rails: quattro with sport differential
As a complement to the new quattro drivetrain, the Audi quattro Concept also features the sport differential, which actively distributes torque between the rear wheels. When turning into or accelerating in a curve, the majority of the torque flows to the outside wheel and pushes the vehicle into the curve, nipping the tendency to oversteer or understeer in the bud.

The sport differential is a state-of-the-art rear differential. A superposition gear comprising two sun gears and an internal gear was mounted on the left and the right of a conventional rear differential. It turns 10 percent faster than the drive shaft.

Chassis
The high-performance Audi quattro Concept dazzles with extreme driving dynamics. It reacts without hesitation, almost reflexively. Its handling is uncompromisingly precise; its stability guarantees maximum driving safety. The steering connects the driver with the road to provide sensitive, finely differentiated feedback.

The wide tracked chassis is rigorously tuned for performance. All of the key suspension components are made of aluminum, thus reducing the unsprung masses. The springs and dampers of the track-controlled trapezoidal link rear suspension are separated to improve response behavior. The links are mounted on a steel subframe on elastic bearings. The five-link front suspension processes the longitudinal and lateral forces separately. The rigid aluminum frame to which it is linked makes the front end extremely rigid.

Up front are anthracite gray, drilled carbon fiber-ceramic discs. They are gripped by red-anodized, six-piston fixed calipers. The ceramic discs are practically fade-free, extremely robust, powerful and durable. Furthermore, they are four kilograms (8.82 lb) lighter than steel discs despite their size.

Audi Q7, 2010

Audi Q7, 2010

 

 

 When it was first rolled out three years ago, the Audi Q7 performance SUV immediately achieved a leadership position - as a sporty, comfortable as well as high-performance recreational and business vehicle on a grand scale. Now Audi is making it even better - more elegant and more efficient, with lower emissions: the Audi Q7 3.0 TDI consumes only 9.1 liters per 100 kilometers (25.85 US mpg). And now it's also available in a new version as a TDI clean diesel, with the world's cleanest diesel technology and even lower fuel consumption of only 8.9 liters/100 km (26.43 US mpg).

The power train: Performance and efficiency
The Audi Q7 is available with six powerful and highly efficient direct injection engines, two of them gasoline-powered and four diesel engines, including the world's most powerful diesel SUV, the Audi Q7 V12 TDI. Their power is transmitted via a convenient and fast-shifting six-speed tiptronic to the quattro permanent all-wheel drive, which distributes it between the axles with slightly more than half to the rear.

The 3.0 TDI puts out 176 kW (240 bhp) and delivers as much as 550 Nm between 2,000 and 2,250 rpm, yet on the EU cycle it consumes only 9.1 liters / 100 km (25.85 US mpg). The optionally available 3.0 TDI clean diesel even consumes 0.2 liters (0.05 US gallons) less.

The equipment: Luxury and high-tech
The Audi Q7 comes with a splendid range of standard equipment. The speed-dependent servotronic steering system is standard, as is a double floor in the cargo area complete with a storage compartment and a dirt tray; there is also a roof rack, an automatic air conditioning system, and an MMI radio operating system complete with a CD audio player and eight loudspeakers.

The world's strongest diesel SUV: The Audi Q7 V12 TDI
Even when it was first rolled out, the Audi Q7 V12 TDI, the world's strongest diesel SUV, had a uniquely distinctive look resulting from its large air intakes. The new version features modifications to the interior and the rear end.

The V12 diesel, with a 6-liter (6,000 cc) engine closely related to that of the R10 TDI racing car - a triple Le Mans winner - delivers 368 kW (500 bhp) and develops a torque of 1,000 Nm between 1,750 and 3,250 rpm.

Acceleration from zero to 100 km/h (62.14 mph) in 5.5 seconds and a capped top speed of 250 km/h (155.34 mph) equal the driving performance of a powerful sports car. Despite these impressive performance data, the V12 diesel gets by on an average of 11.3 liters of fuel per 100 km (20.82 US mpg). Its luxurious standard equipment includes 20-inch wheels, a Bose sound system, and many additional features.

Audi e-tron Spyder Concept, 2010

Audi e-tron Spyder Concept, 2010

 

 

 

Audi presents the Audi e-tron Spyder Concept, the study of an open sports car, at the fall 2010's largest auto show. The show car, with plug-in hybrid drive, is 4.06 meters (13.32 ft) long, 1.81 meters (5.94 ft) wide and only 1.11 meters (3.64 ft) high. The two-seater is equipped with a 221-kW (300-hp) twin-turbo V6 TDI at the rear axle and two electric motors producing a total of 64 kW at the front axle.

The Audi e-tron Spyder Concept's low total weight of only around 1,450 kilograms (3,196.70 lb) combined with the high-torque TDI and the two electric motors results in respectable performance. The car accelerates to 100 km/h (62.14 mph) in just 4.4 seconds, and top speed is electronically governed at 250 km/h (155.34 mph).

The Audi e-tron Spyder Concept can combine the powerful torque of its TDI - the diesel engine generates 650 Nm (479.42 lb-ft) and the total of 352 Nm (259.62 lb-ft) of its two electric motors during acceleration in a process known as "boosting."

The intelligent distribution of power allows for optimal dynamics in every situation. The targeted application of power to the front wheels improves longitudinal dynamics while also improving lateral dynamics when cornering. This is because torque vectoring - the as-needed distribution of torque between the left and right wheels of the two axles - enables an exhilarating degree of driving precision and excellent agility.

The combination of a highly efficient TDI and electric drive also provides for excellent fuel economy and amazingly low emissions. The Audi e-tron Spyder Concept requires on average just 2.2l diesel/100 km (106.92 US mpg), corresponding to CO2 emissions of 59 g/km (94.95 g/mile). A range of more than 1,000 kilometers is possible with the 50-liter (13.21 US gallons) tank.

Design
The Audi e-tron Spyder Concept features what is without a doubt the most advanced and simultaneously the most consistent evolution of the current Audi design language, while also providing initial hints at the design language of future Audi sports cars. It reinterprets the most important design elements that already characterized the previous e-tron concept vehicles. This also ensures the necessary formal differentiation to the purely electric-powered Audi e-tron shown at the 2010 Detroit Motor Show.

1.81 meters (5.94 ft) wide, just 4.06 meters (13.32 ft) long and only 1.11 meters (3.64 ft) in height: these are the classic proportions of an open, high-performance sports car. Compared to the coupé concept car in Detroit, the length and width have increased by 13 cm (5.12 in) and 3 cm (1.18 in), respectively, to underscore the sporty aspiration of the design. This further enhanced the powerful and compact overall appearance that characterizes both vehicles and links them to the sportiest production Audi, the R8.

Interior
Visual and functional references to the fundamental concept of lightweight construction characterize the purist interior design. They establish a connection between proven Audi genes and new formal hallmarks. Typical for the Audi design idiom is the reduction of the architecture, controls and information output to the essentials in favor of a tidy overall impression.

The slim dash has a curve that extends laterally into the door panels. With no need to allow for a transmission, shifter and cardan tunnel, the designers again took advantage of the opportunity to create a particularly slim and lightweight center tunnel and convex, arching center console for the Audi e-tron Spyder Concept with hybrid drive. The only control element other than that of the MMI is the flush-mounted selector lever for the automatic transmission, which extends upward from the tunnel when the vehicle is started.

The cockpit of the Audi e-tron Spyder Concept is also oriented toward the driver - a further characteristic Audi trait. Instead of the classic instrument cluster, the concept car is equipped with a large, display with integrated MMI functions and flanked by two round dials. The MMI can be controlled via a touch-sensitive control panel on the steering wheel - an element inspired by modern smartphones. It can also be controlled via the MMI control unit (MMI touch) on the center console. The steering wheel itself is clearly flattened off at both the top and bottom, in a clear reference to motor sport. Speed is displayed in digital form only. The dial instrument with information about the drive system can be chosen via the menu item "Drive."

The equally racing-inspired lightweight bucket seats combine excellent lateral support with comfort. Contrasting colors and stitching delineate the various zones of the interior. The colors and the high-quality materials combine elegance and sportiness.

ASF body
Systematic lightweight construction is a crucial prerequisite for efficiency and range, while also being the primary foundation for exhilarating driving dynamics. The Audi development engineers drew on the core competence of the company for the Audi e-tron Spyder Concept. The body structure is based on Audi Space Frame (ASF) technology and was realized as a hybrid construction, with the hood and numerous aerodynamic components made of carbon.

In ASF technology, the body's supporting structure is made of extruded aluminum sections and die-castings. Aluminum panels are incorporated into this skeleton to form a positive connection and perform a load-bearing role. Each individual component of the ASF space frame is optimized for its specific task by the use of widely differing shapes and cross-sections, combining maximum stability with minimal weight. Despite the complex drive system layout with two electric motors and their respective drive systems plus the TDI engine, the Audi e-tron Spyder Concept only weighs around 1,450 kilograms (3,196.70 lb).

Engines and transmissions
Audi has long proven the perfect synthesis between a highly advanced sports car and TDI technology. With the TT, Audi become one of the first manufacturers anywhere in the world to successfully bring a diesel sports car to market, a decade after the Audi Cabriolet paved the way for diesel engines in this segment. And the Audi R8 TDI Le Mans concept car was the first supercar to be fitted with a twelve-cylinder diesel engine with 500 hp and 1,000 Newton meters (737.56 lb-ft) of torque.

The Audi e-tron Spyder also draws on this recipe for success - albeit in a revolutionary new combination. This marks the first use of a new generation of the six-cylinder, 3.0 TDI that breathes through two turbochargers and produces 221 kW (300 hp). That is another 50 hp more than the previous stage, which debuted a few months ago in the new Audi A8.

The drive's characteristic is even more exciting than the abstract numbers. Thanks in no small part to the fact that the peak torque of the electric motors is available immediately, the Audi e-tron Spyder Concept accelerates with catapult-like thrust. Short passing maneuvers on interurban roads can be pulled off as spurts that are every bit as relaxed as they are fun, even without having to downshift.

The noise level of the low-revving TDI is typically low. The six-cylinder unit behind the occupants issues a sonorously sporty growl under load, but never becomes loud. A surprising effect also present in the Le Mans-winning Audi R10 and R15 race cars, which are also powered by TDI engines.

Audi A8 Hybrid Concept, 2010

Audi A8 Hybrid Concept, 2010

 

 

 

 

Power like a big V6, fuel economy like a modest four-cylinder unit - Audi presents the Audi A8 Hybrid Concept as a technology concept at the 2010 Geneva Motor Show. Its two propulsion units - a 2.0 TFSI and an electric motor - develop a total output of 180 kW (245 hp) of system power and 480 Nm (354.03 lb-ft) of torque. This enables the Audi A8 Hybrid to accelerate in 7.6 seconds from zero to 100 km/h (62.14 mph) and to achieve a top speed of 235 km/h (146.02 mph). Yet its average fuel consumption amounts to only 6.2 liters (37.94 US mpg) per 100 km - the CO2 equivalent is 144 grams per km (231.75 g/mile).

The technology of the Audi A8 Hybrid Concept
The combustion engine of the Audi A8 Hybrid Concept is the 2.0 TFSI - a high-tech powerplant. This four-cylinder unit, which has been named "Engine of the Year" five times in a row since 2005, is an example of Audi's downsizing philosophy. It combines direct fuel injection with turbocharging and the AVS Audi valvelift system, which regulates the valve lift in two stages. In combination with the adjustable intake camshaft, the Audi valvelift system improves cylinder charging and ensures spontaneous and powerful torque build-up. The 2.0 TFSI delivers 155 kW (211 hp) and 350 Nm (258.15 lb-ft); the torque value remains constant from 1,500 to 4,200 rpm.

In the crankcase of the four-cylinder unit, which has a displacement of 1,984 cc, two balancer shafts offset second-order inertial forces to ensure virtually vibration-free and pleasantly quiet operation that goes well with the luxurious character of the Audi A8. All components are optimized to minimize friction. The flow-rate-regulated, pressure-controlled oil pump further reduces fuel consumption.

Electric motor with ample propulsive power
A hydraulically operated wet clutch links the 2.0 TFSI with the electric motor. Its control requires the utmost precision, and a great deal of know-how has been expended to achieve its smooth, precise and swift operation. The synchronous motor, which is continually excited, also serves as a generator that develops 33 kW (45 hp) of power and 211 Nm (155.63 lb-ft) of torque. Its full power is available practically right from standstill and contributes to a sportily powerful start-up. Since an electric motor also develops heat, its housing is furnished with cooling ducts. Interposed between the electric motor and the wheelset of the eight-speed tiptronic, which is controlled entirely by electronics, is an additional cut-out clutch. In conjunction with the electric unit, this functions as a torque converter. The propulsive power of both drive systems is applied to the road through the front wheels.

Lithium-ion technology - the battery
The energy storage system of the Audi A8 Hybrid Concept is mounted in the rear section. This state-of-the-art lithium-ion battery is more compact and weighs less than other types but is substantially more powerful. It is protected by a high-strength housing, and a ventilation module ensures that it always operated within the ideal temperature range. Yet the Audi A8 hybrid Concept also provides ample luggage space of 400 liters (14.13 cubic feet)

Several subsystems that operate on engine power in a conventional car have been modified right from the start for use in the Audi A8 Hybrid Concept. The compressor in the climate control system runs entirely on electric power. The steering system is electromechanical as well. The brake booster too is supplied by a demand-controlled electric vacuum pump. During electrical - i.e. recuperative - braking actions, a sophisticated control system ensures that the ABS and ESP functions operate properly.

The power electronics unit manages the interaction of the systems. Its pulse control inverter regulates the interplay of the battery and the electric motor. The DC-DC converter supplies power to users on the onboard network. The power electronics unit, which is connected to the battery and the electric motor by high-voltage cables, is located in the engine compartment.
 

Driving experience
The Audi A8 Hybrid, which weighs 1,885 kilograms (4,155.71 lb), drives as if it had a big six-cylinder gasoline engine or a TDI under its hood. From zero to 100 km/h (62.14 mph) the vehicle accelerates in 7.6 seconds, and it can continue to accelerate up to 235 km/h (146.02 mph). Yet its fuel consumption according to the EU cycle is only 6.2 liters per 100 km (37.94 mpg), corresponding to 144 grams CO2/km (231.75 g/mile). In city traffic, the hybrid drive uses about 20 percent less fuel than a conventional drive. Both the car's performance and its fuel economy benefit substantially from a major advantage of the A8 model series - its lightweight aluminum body based on the Audi Space Frame principle (ASF).

The hybrid drive is designed for fully electric-powered driving up to 65 km/h (40.39 mph) and for a distance exceeding two kilometers - especially well-suited for driving in the city or residential suburbs. When conditions permit, the driver can also select the electric mode by actuating a separate e-key in the cockpit. Both the display screen of the instrument cluster and the large monitor of the MMI operating system on the dashboard present all momentary power flows in brilliant graphics.

When the Audi A8 Hybrid Concept starts moving, both of its engines interoperate closely to suit varying power demands. Above 65 km/h (40.39 mph) the combustion engine alone does all the propulsive work, while the electric motor supplies onboard users and recharges the battery.

When the driver lets up on the gas, the combustion engine is disconnected from the drivetrain, so the Audi A8 Hybrid "sails". In braking and slow-down phases, the e-motor functions as a generator - recuperating energy efficiently and feeding it into the battery.

The design of the Audi A8 Hybrid
This near-production concept car has 21-inch, two-colour wheel rims styled with highly three-dimensional surface areas. The exterior paint job of the Audi A8 Hybrid Concept is in "Prism Silver" with "Spectra Flair" as an accent color - a rainbow effect that's accentuated in reflected light along creases and seams on the body. The prominently located "hybrid" lettering on both front fenders leaves no doubt about what kind of car this is. The accentuation of its width by a prominent low horizontal spoiler edge and a chrome strip conveys the vehicle's solid stance on the road.

Audi S5 Cabriolet, 2010

Audi S5 Cabriolet, 2010

 

 

 

 

The engine in the Audi S5 Cabriolet is a newly developed, supercharged, three-liter V6. The pressure in the 3.0 TFSI is generated by a mechanical supercharger - with impressive results: The power output tops out at 245 kW (333 hp), the torque between 2,900 and 5,300 rpm remains constant at a generous 440 Nm (324.53 lb-ft). The powerful thrust and the spontaneous, aggressive response make for a fascinating driving experience. The Audi S5 Cabriolet is catapulted in 5.6 seconds from zero to 100 km/h (62.14 mph) and accelerates up to a preset top speed of 250 km/h (155.34 mph). Yet at 9.6 liters per 100 km (24.5 US mpg), its fuel efficiency is highly impressive (preliminary values).
Standard equipment of the Audi S5 Cabriolet includes the servotronic, the seven-speed S tronic and the quattro drive system package. The sport differential is optional. A sport suspension keeps the body close to the road. The 18-inch cast aluminum wheels are equipped with 245/40 tires. The black brake calipers are emblazoned with S5 emblems. The acoustic top, xenon plus headlights, electrically adjustable sport seats with Alcantara leather upholstery, and a multifunction sport steering wheel are also standard equipment.
Diverse design features contribute to a distinctively sporty styling, including modifications at the lower front and back panels, at the air intakes and at the tailpipes. In the interior, special seat upholstery, door sill trims and inlays in matt brushed aluminum underscore the high-quality, dynamic style of the high-end model. The pointers of the instruments are illuminated white to contrast with the gray scales.

Audi A5 Cabriolet
Dynamic and wonderful to look at, the new Audi A5 Cabriolet is a real Audi, and an especially exciting one at that. The four-seater with the fabric top combines a sporty character with the fascination of open-top driving, refined comfort, and great everyday utility. Seven powerful engines, an agile suspension and a wide range of high-end options make the new Audi model the most attractive mid-range convertible. The top-of-the-line model of Audi's new family of convertibles is the Audi S5 Cabriolet. The engine of the S5 Cabriolet is the newly developed, supercharged three-liter V6 with gasoline direct injection. Prices start at EUR 37,300 for the 1.8 TFSI with 118 kW (160 hp) and six-speed manual transmission. Delivery of the first Audi A5 Cabriolet models will begin in the second quarter of 2009.
Like all open-top Audi models, the new Audi A5 Cabriolet too has a classic fabric top - which endows it with a striking silhouette of dynamic elegance. The lightweight softtop opens in 15 seconds - and closes in 17 seconds. The fully automatic open/close drive comes as standard. An acoustic top is optionally available, which reduces wind noise almost to the hardtop level.

When opened, the Audi A5 Cabriolet top folds down so effectively that very little trunk space is used up - leaving 320 liters (11.3 cu ft) of unused storage volume, clearly the best value in its field of competitors. The softtop compartment lowers itself automatically when the top is opened.
Equally useful is the fold-down rear seat backrest with the large pass-through between the luggage space and the interior, which increases the storage volume to a generous 750 liters (26.49 cu. ft.).
Automatic seat belt extenders round out the comfort in the interior. Neck-level heating is optionally available for the front seats. The optional leather seats are coated with a special layer to reduce solar heating. There is comfortable room for four persons. The refined ambiance combines with exemplary ergonomics to convey an atmosphere of sporty elegance. Ultra-high-strength steels and selective reinforcements of the body ensure maximal rigidity and crash safety.

Fascinating dynamics: Audi drive select
The perfect addition to this technology package is the Audi drive select vehicle dynamics system, which enables the driver to chose among three different engine maps controlling the characteristics of the fuel feed, the shifting points of the seven-speed S tronic and multitronic, and the mode of operation of the servotronic steering system.

Audi drive select is only available in combination with one or more of three additional technologies - the sport differential, the adaptive control for the shock absorbers, and dynamic steering. This is an additional high-tech solution: Its superposition gear varies the gear ratio as a function of the driving speed by up to 100 percent.
The new Audi A5 Cabriolet features a rich array of equipment, including 17-inch alloy wheels, automatic air conditioning, and an audio system with a CD player. One of the highlights among the optional equipment is the third-generation MMI operating system, which provides many attractive navigation and entertainment functions.
As the dynamic top-of-the-line model of the new production series, the Audi S5 Cabriolet occupies a very special position. Its three-liter TFSI - a V6 with turbocharger - unfolds its 245 kW (333 hp) and 440 Nm (324.53 lb-ft) of torque impressively: It responds tenaciously to the throttle and delivers excellent driving performance. The quattro drive, a sport suspension with 18-inch wheels and a number of special equipment details underscore the athletic power of the Audi S5 Cabriolet.

The exterior design
The Audi A5 Cabriolet combines Audi's progressive styling with the fascination of an open-top car. The long engine hood, the sharp lines, the sweep of the shoulder contour, the elegantly curved surfaces, the large wheels, the distinctive front end, and the expressive tail all interact to create a sculptural, sensuous whole. The Audi A5 Cabriolet is 4.63 meters (15.19 ft) long and 1.85 meters (6.07 ft) wide, but only 1.38 meters (4.53 ft) tall: the sportiest proportions in its class.
The styling of the front end is dominated by the single-frame grille, which is flanked by large air intakes. The exquisite design of the headlights makes them look like technical jewels. The daytime running lights of the optional xenon plus headlights consist of LEDs. An aluminum molding lends high gloss to the windshield frame.
The looks of the tail end are sharpened by horizontal lines, broad tail lights, straight tailpipes, and a distinctly colored diffuser insert. The trunk lid bears an unobtrusive spoiler lip. The xenon plus headlight option comes complete with LED taillights, which create a distinctive light pattern.

The convertible top
The fabric top with the large glass rear window fits smoothly into the design profile. This is one of several reasons why Audi preferred it to a folding steel roof. What's more, its construction is much lighter in weight, which reduces the overall weight of the Cabriolet and lowers its center of gravity. The outer skin of the top is available in a choice of four colors, the inside in three.
The softtop consists of three layers. The intermediate layer is a cushioning pad. In the optional acoustic top, which reduces wind noise almost to hardtop level, this is replaced by a foam layer up to 15 millimeters (0.59 in) in thickness. The acoustic top comes with a ceiling light for the rear seat - a solution usually only found in the topmost convertible luxury segment.
In both versions, a hydraulic pump and four operating cylinders that move the top are actuated when a pushbutton on the central console or on the optional remote access assistant is depressed. It takes 15 seconds to open the top, 17 seconds to close it. Both actions can also be actuated while driving at up to 50 km/h (31.07 mph) - which makes driving much more comfortable.

When opened, the top is retracted underneath a fixed cover, where it is folded down into an extremely compact shape. Its storage compartment, which automatically lowers itself into the trunk space, only takes up a few centimeters in height - and only 60 liters (2.12 cu ft) of the 380 liters (13.42 cu ft) of luggage space. The remaining 320 liters (11.3 cu ft) with the top open are by far the best value among comparable vehicles. What's more, the low position of the loading lip makes loading and unloading easier. The wind deflector, which is supplied as standard, can be stored in the spare-wheel well to save space.
A very convenient feature in the Audi A5 Cabriolet are the split folding rear seat backrests. They can be easily unlocked by actuating levers in the trunk and drop automatically onto the seat cushions. The standard pass-though is 70 centimeters (27.56 in) wide. The loading space behind the front seatback is 1.76 meters (69.29 in) long, providing a total storage volume of 750 liters (26.49 cu ft).

The body
As is typical of Audi models, the A5 Cabriolet has an extremely rigid body. This is a prime reason for its precise driving performance, its high comfort level, and its maximized crash safety.
In the construction of the body-in-white, several innovative technologies are used. A prime example are the ultra-high-strength steels with their extremely high tensile strength, which Audi manufactures in-house using hot forming. The front fenders of the Audi A5 Cabriolet are made of aluminum to lower the weight and to optimize axle load distribution. An enclosed underbody improves the airflow and thereby the fuel efficiency.
A whole array of additional reinforcement parts compensates for the absence of a solid roof. They are located in the front section, in the side skirts, in the windshield frame, and in the rear section. Located between the interior and the luggage section is the rollover protection. When a rollover threatens, spring-loaded aluminum braces are raised behind the rear seat headrests. Door-mounted head and chest sidebags provide protection in the event of a lateral impact.

The interior
With its generous wheelbase of 2.75 meters (9.02 ft) and the longest interior in its class, the Audi A5 Cabriolet has plenty of room for longer trips. That's also true for the rear seats, which can be optionally divided by a center console with two cup holders.
Elegance in flowing lines, functional ergonomics, and top-quality craftsmanship are the principal characteristics of the interior - and this too is typically Audi. The teardrop-shaped settings of the instruments have already become modern classics. The centrally mounted onboard monitor is standard equipment. The formed-plastic console focuses on the driver. Flowing lines link it to the central tunnel and the door linings. If the customer has ordered either one of the two navigation systems it comes with the highly convenient MMI operating system - the best solution on the market.
The low standard seats provide excellent control and support. Using seatbelts is facilitated by electric seat belt extenders. Special solutions are available as alternatives: firm sport seats, electric seat adjustment and heating - as a separate option also for the back seats.
In the climate-controlled comfort seats, small fans and an automatic auxiliary heater ensure luxurious comfort. This option provides neck-level heating - ducts on the topside of the seatback emit warm air that keeps the back of the head and neck warm. With its three-level control, the headroom heater is also available for sport seats. It prolongs the open-air season in the Audi A5 Cabriolet.
Another special feature is provided in the optional leather upholstery: a special coating inhibits solar heating while the Cabriolet is parked in the sun with the top down. This coating reflects infrared radiation and thus lowers the surface temperature by up to 20 degrees Celsius. Audi offers a choice of several seat coverings up to and including Fine Nappa leather. Inlays come as standard in Micrometallic platinum; aluminum and three different kinds of wood are available as options.

The engines
In the propulsion system of the A5 Cabriolet too Audi has consistently relied on innovative technologies: All five engines - the two TDIs and the three gasoline engines - use direct injection. They are impressive evidence that, at Audi, efficiency and dynamics go together and are interdependent.
The most powerful gasoline engine in the Audi A5 Cabriolet is the 3.2-liter FSI. It operates with the innovative Audi valvelift system, which varies the lift of the intake valves in two stages. As a result, the gas exchange improves and the throttle can be left open more often, minimizing throttling losses - which in turn boosts the torque and the power output while reducing fuel consumption. The V6 delivers up to 195 kW (265 hp) as well as 330 Nm (243.4 lb-ft) between 3,000 and 5,000 rpm. With front-wheel drive and multitronic it accelerates the Audi A5 Cabriolet in 6.9 seconds to 100 km/h (62.14 mph) - and up to a top speed of 246 km/h (152.86 mph). Its average fuel efficiency is an impressive 8.6 liters/100 km (27.35 US mpg). An optional alternative is quattro all-wheel drive, combined with the new seven-speed S tronic.
The 2.0 TFSI likewise attests to Audi's leadership position in engine design. This four-cylinder engine also uses the Audi valvelift system - but here it acts on the exhaust valves, with similar advantages as in the V6. Audi sells the two-liter turbo in two versions.

The transmission
Audi provides a choice of three different transmissions for the Audi A5 Cabriolet. The 2.0 TFSI with 155 kW (211 hp) comes with a six-speed manual transmission as standard, which excels in its short shifting travels and high operating precision. Both the two-liter engine and the 3.2 FSI are available with the multitronic continuously variable automatic transmission as an option, which combines smooth operation with high efficiency and a fuel-saving transmission ratio. For a dynamic driving style the multitronic is available with a sport program and a manual mode with eight fixed speeds.
For the more powerful version of the 2.0 TFSI and for the 3.2 FSI, the seven-speed S tronic is available as an option; in the 3.0 TDI it is standard equipment. This new high-tech dual-clutch transmission changes gears in a few hundredths of a second, and so smoothly that the driver hardly notices it. What's more, it is highly efficient and fuel-saving. The driver can let the seven-speed S tronic shift automatically or interact, if desired, via rocker switches on the steering wheel.
The seven-speed S tronic has been designed for use with the quattro permanent all-wheel drive. It is optionally available for the high-end diesel series and for the two powerful gasoline engines. The quattro drive system is dynamically designed - during normal driving it distributes the forces in a 40:60 ratio between the front and the rear. If one wheel skids, a center differential that operates purely mechanically transfers most of the power to the axle with the better traction.
