Distinct sports appeal and supreme comfort – these are the two defining characteristics of the Audi A8. At the time of its market launch three years ago, this large saloon shot straight to the top of the luxury segment thanks to its dynamic qualities. The brand with the four-ring emblem is now unveiling a sporty top model of the very highest calibre in the luxury segment: the new Audi S8.
It will be appearing on the market in the mid of 2006, with a price tag of EUR 97,600.
The Audi S8 is equipped with a new V10 engine that capitalises on the expertise of the super sports car Lamborghini Gallardo. The 10-cylinder power unit develops 450 bhp of power and 540 Nm of torque from a swept volume of 5.2 litres. The torque value is achieved at as low an engine speed as 3,500 rpm. As on the Le Mans winning R8, the most successful racing car in the world, FSI petrol direct injection assures superior power output in the Audi S8. This luxury saloon sprints from 0 to 100 km/h in 5.1 seconds, and is electronically governed at 250 km/h.
In outfitting the S8 with the V10, Audi is introducing an engine technology that has long been demonstrating its performance potential in the world of Formula 1 racing. The Italian super sports car brand Lamborghini, a subsidiary of Audi, likewise regards the ten-cylinder engine as synonymous with dynamic power. This engine concept has a much more sporty emphasis than a comparable twelve-cylinder power unit. Ten-cylinder engines are more compact and lighter; thanks to the smaller number of components, they have lower moving masses and less internal friction.
The 450 bhp V10 is the second generation of Audi V-engines, all with a 90-degree included angle and a spacing of 90 millimetres between cylinder centres. Key areas of the Audi version have been reengineered compared with the engine in the Lamborghini Gallardo. The bore has been increased from 82.5 to 84.5 mm; the stroke is 92.8 mm and the displacement 5204 cm3. A so-called bedplate structure – an intermediate frame – reinforces the extremely compact crankcase, which is made from cast aluminium.
With its crankpin offset of 18 degrees, the V10 fires at the ideal spacing of 72 degrees crankshaft angle. A balancing shaft located within the "vee" eliminates the so-called free inertial forces of the first degree and also contributes towards the engine's notable refinement. All four camshafts can be adjusted continuously by 42 degrees crankshaft angle, depending on load and engine speed, to optimise filling of the combustion chambers and thus enhance the power output. They are driven by no-maintenance chains and actuate the 40 valves via roller cam followers.
The V10 in the new Audi S8 uses FSI petrol direct injection. This permits a high compression ratio of 12.5:1 and a correspondingly more effective combustion process based on a lambda value of 1. The common rail injection system delivers the fuel directly to the combustion chambers in precisely metered amounts, at a pressure of up to 100 bar.
The two-stage magnesium variable intake manifold incorporates electronically controlled tumble flaps that induce a swirling movement in the air drawn in. Four close-coupled main catalytic converters take charge of exhaust emission control for the V10 of the Audi S8. FSI technology has impressively demonstrated its potential in motor sport – the R8 racing car equipped with it participated in the
Le Mans 24 Hours on five occasions for Audi, winning the race on four of those occasions.
The powerful ten-cylinder engine is designed for impressive torque as well as engine power. It generates 450 bhp at 7,000 rpm, but musters up 540 Nm of torque at just 3,500 rpm. 90 percent of the torque is available from as low as 2,300 rpm. The V10 exhibits spontaneous throttle response and very refined running, and under load it also produces sonorous acoustics, as befits a dynamic car.
The V10 imparts the luxury saloon with the road performance of a high-calibre sports car. The Audi S8 races from 0 to 100 km/h in 5.1 seconds. The speed is not governed electronically until the needle reaches 250 km/h. The engine shows a distinctly modest thirst, needing only 13.9 litres of fuel per 100 kilometres – a figure achieved partly thanks to the consistent use of lightweight design, which clearly sets the A8 range apart from its competitors. With its innovative aluminium body, the Audi Space Frame ASF, the S8 weighs just 1940 kilograms, including the dynamic, sure-footed quattro drive. On the new Audi S8, every horsepower has to propel just 4.31 kilograms – the power-to-weight ratio of a sports car.
The 2008 R8_
Audi has unveiled the 2008 R8 — its first ever mid-engine sports cars. Sales will begin in the first half of 2007 for the United States and Europe. The car has a 420 horsepower high-revving V8 engine and all-wheel-drive. It uses the mid-engine Lamborghini Gallardo platform, and will somewhere between $80,000 and $110,000 — positioning it squarely against the BMW M6, Porsche 911, and Aston Martin Vantage. It features a choice of LED or Xenon headlamps surrounded by LED running lights and indicators. LEDs are also used in the engine bay to make the impressive V8 visible even at night. Both a standard manual and an automated manual transmission will be offered. Claimed 0 to 62 mph time is 4.6 seconds, though this number is likely conservative.
The sporty interior is dominated by a totally driver-oriented cockpit architecture, integrating the driver between the dashboard and the high centre console. The instrument panel above the console is angled slightly towards the driver. The flat-bottomed steering wheel is a typical feature of the sportiest Audi models, and also enables comfortable sports car entry and exit.
The sports seats are trimmed as standard in a Leather/Alcantara combination, or optionally in full leather. Alternatively, the R8 can also be fitted with bucket seats, specially developed by quattro GmbH. There is plenty of room for the two occupants, with comfort levels well beyond the norm of high-performance sports cars. There is space behind the seats to stow large bags, or even two golf bags. The luggage compartment at the front has a capacity of 100 litres.
With numerous trim variants and applications in Piano finish or Carbon sigma, there are few limits to the range of customisation options for the interior.
The drive train
At 7,800 rpm the 4.2-litre engine delivers 309 kW (420 bhp) of power output. Peak torque is 430 Newton-metres from 4.500 to 6,000 rpm. And no less than 90 per cent of this maximum torque is maintained consistently throughout a wide engine speed range from 3,500 all the way to 7,600 rpm. As a result of these qualities, the eight-cylinder power unit provides maximum thrust in virtually any driving situation.
The performance figures are equally impressive: the R8 accelerates from a standstill to 100 km/h in 4.6 seconds and reaches a top speed of 301 km/h.
The engine is a high-revving unit. The maximum engine speed is 8,250 rpm. The advantages of this principle are superior power output at high engine speeds and a smooth, eager responsiveness all across the revs range. Added to this are its agility, liveliness and engine sound, which is similar to that of a race car.
The Audi R8's dry sump lubrication – another technology originating directly from motor racing – provides the ideal basis for maximum longitudinal and lateral acceleration. It allows the V8 to be installed lower, thereby lowering the centre of gravity and further enhancing driving dynamics.
Two transmissions are available: a manual 6-speed gearbox or optionally the Audi R tronic sequential-shift gearbox, with a joystick gear-shift on the centre console and, most especially, the paddles mounted on the steering wheel. 'Shift by wire' technology provides for very fast gear-shifting and an outstanding power-to-weight ratio, allied to compact gearbox dimensions. The Sport mode, with its fast shifting, guarantees the absolute maximum in terms of driving fun. An automatic mode can also be selected.
The car is fitted with permanent four-wheel drive, which distributes the power variably to the front and rear axles by way of a viscous clutch. On the Audi R8 the legendary quattro system is adapted to the axle load distribution typical of mid-engined cars.
The chassis
The chassis features forged aluminium double wishbones at the front and rear. At the front they are triangulated, while at the rear the top one is triangulated and the bottom one is a triangulated wishbone with a track rod. This provides for optimum wheel control, and is a geometry which has proved itself to be the ideal solution in delivering agility, maximum steering precision and precisely defined self-steering characteristics.
Direct, hydraulic rack-and-pinion steering provides optimum feedback to assist the driver.
The spring and damper set-up is stiff in order to deliver maximum driving dynamics, while still providing a quite astonishing level of ride comfort. This is particularly true when the 'Audi magnetic ride' adaptive damper system is chosen as an alternative to the standard gas-filled shock absorbers.
The reason for this is that these shock absorbers employ an innovative technology. Instead of the conventional damper fluid, a magnetorheological fluid is used – in other words, a fluid whose viscosity can be influenced by an electromagnetic field. This effect enables the damping characteristic to be influenced electronically at will and instantaneously, by applying a voltage to the electromagnets.
Audi magnetic ride uses this property to deliver the correct damping forces in every driving situation, thus optimising ride comfort and driving dynamics. A computer equipped with sensor technology determines the prevailing driving situation in a matter of milliseconds. Drivers can choose from two driving programs depending on whether they want to drive in a highly sporty style – with the magnetorheological fluid adjusted to a low viscosity – or with the emphasis more on ride comfort.
The Audi R8 is fitted with 6-arm 18-inch wheels as standard, and can optionally be ordered with 19-inch wheels. The 235/40 size tyres at the front and up to 285/35 at the rear provide the necessary road-holding. This tyre configuration also ensures that this mid-engined sports car is always able to translate the dynamism of its drive train and chassis into optimum grip and maximum lateral dynamics.
The mid-engined sports car's long wheelbase and extremely low centre of gravity ensure that it always retains maximum stability, resulting in superb agility, finely attuned responsiveness to any driver input, and high levels of safety.
Equipment and trim
Even the standard equipment of the Audi R8 meets the high demands of customers in this segment. Xenon plus lights, LED rear lights and daytime running lights, 18-inch aluminium wheels, an audio system with 7-inch monitor, an anti-theft alarm and Leather/Alcantara interior trim are just some of the items on the extensive list of standard features.
The range of optional extras leaves virtually nothing to be desired. A Bang & Olufsen sound system, featuring an output of 465 watts and 12 specially designed speakers, delivers surround sound of the highest standard. A microphone-based vehicle noise compensation system adjusts audio levels to changing road conditions and speeds.
The acoustic parking system and a rear-view camera help the driver to manoeuvre into even the tightest of spaces. The radio/navigation system plus, featuring a large-format colour monitor and MMI keypad, combines extensive functionality with extreme user-friendliness. A range of coordinated and ideally combinable design and leather trim packages from Audi and from quattro GmbH can turn any R8 into the customer’s personal dream car. The wheels range offers design alternatives in sizes of 18 and 19 inches, fitted with 235/35 size tyres at the front and up to 295/30 at the rear. A total of eight exterior colours are available, from Ibis White to Phantom Black, pearl effect.
The 2007 RS4...
New dimensions in driving dynamics combined with innovative ideas and concepts – and, in addition, exciting lines and a level of equipment living up to even the highest luxury performance standards: The new Audi RS 4 combines the latest high-performance motoring qualities offered by quattro GmbH in a thoroughbred sports saloon with supreme everyday driving qualities in the premium segment. Indeed, the new RS 4 is the top-of-the-range model in the A4 series, a development all-new from the ground up.
Numerous technical achievements – many of which hail from motorsport – give the new Audi RS 4 its unique class and character. These features include the high engine speed concept now being introduced for the first time in a production Audi, innovative FSI technology, as well as the latest generation of quattro drive with asymmetric/dynamic distribution of torque. Developing a maximum output of 420 bhp, the V8 revs up to a speed of 8250 rpm. With its displacement of 4163 cc, this engine exceeds the magical barrier of 100 bhp per litre - truly outstanding in a production saloon. Maximum torque of 317 lb-ft comes at 5500 rpm in this very compact engine, with 90 per cent of the engine’s torque consistently available between 2250 and 7600 rpm. The result is excellent muscle and pulling force at all times, enabling the driver whenever he – or she – wishes to drive in truly relaxed style without frequent gear changes.
Audi has chosen its trendsetting and groundbreaking FSI technology for the RS 4 saloon, direct gasoline injection ensuring even more effective combustion of the fuel/air mixture and, as a result, an even better power yield. This is matched by the highly responsive development of power, the RS 4 accelerating to 62 mph in 4.8 seconds and reaching 125 mph in 16.6 seconds. Top speed is cut off electronically at 155 mph.
