Audi R8 5.2 FSI quattro: Breathtaking Performance
INGOLSTADT, Germany - Audi is launching the next variant of its top-of-the-line model. With the R8, the brand has established itself at the forefront of high-end sports cars from the very start - and now comes the 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 R8 V10 takes pole position against the competition.
The 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 R8 racing car Audi is developing for customer teams in conformance with the GT3 rules.
The V10 engine in the production sports car will be almost identical in construction to the one in the racing version. Its displacement is 5,204 cc, at 6,500 rpm it delivers 530 Nm (390.91 lb-ft) of torque, at 8,000 rpm its power tops out at 386 kW (525 hp).
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 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 R8 V10 with R tronic gets by on an average of 13.7 liters per 100 km (17.17 US mpg).
For maximum dynamics: low center of gravity engine
The technical refinements of the long-stroke ten-cylinder engine include dry sump lubrication, which allows the engine to be mounted low within the chassis. The wide cylinder angle of 90 degrees also makes for a low center of gravity. The crankcase is a high-strength aluminum-alloy casting produced in a complex process. The connecting rods are made of forged steel, the pistons of aluminum. The four camshafts are chain-driven and each is adjustable through 42 degrees. This provides great latitude in controlling the valve timing. In combination with the straight, flow-optimized ducts of the intake manifold, this improves the charge throughout the entire speed range.
The R8 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 R8 V10 takes off in a vehement quick-start with electronically controlled tire slip - both with the R tronic and with the manual transmission.
A contributing factor to the wide lead in traction and driving safety of the Audi R8 V10 over the competition is quattro all-wheel drive - it's the superior technology especially for a high-performance sports car. Four powered wheels get more grip than two. They enable the driver to step on the gas sooner when coming out of a curve. It's not only the traction that benefits, but also the transverse dynamics and the stability.
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.
The wheel suspensions on dual aluminum wishbones front and rear - a classic racing technology - are optimized for neutral self-steering characteristics. Even more than in the eight-cylinder R8, this setup is designed for maximum performance. 19-inch wheels equipped with tire pressure monitoring display are standard equipment. Their 10-spoke Y design is exclusive to the R8 V10. Tire sizes are 235/35 front and 295/30 rear.
The car features a high-end damper technology as standard: Audi magnetic ride adapts the characteristics of the suspension in milliseconds to the nature of the road surface and to the driving style. Suspended in the oil of the shock absorbers are tiny magnetic particles which, when a voltage is applied, rearrange themselves so as to slow down the flow of oil through the valves.
In the R8 V10, deceleration is provided by an extremely muscular braking system - eight brake pistons at the front and four at the rear grasp the brake disks, which are ventilated and perforated to ensure unimpeded heat transfer. The brake disks on the front axle have a diameter of 380 millimeters (15 in); the rear discs span 356 millimeters (14 in).
The R8 5.2 FSI quattro is optionally available with a ceramic brake system whose disks are made of a composite material containing high-strength carbon fibers and abrasion-resistant silicon carbide. These are especially light: their combined weight is nine kilograms (19.84 lb) less than the weight of equivalent steel disks. The ceramic brakes can easily cope with the harsher requirements of racing, won't corrode, and have a typical service life of 300,000 kilometers (186,400 miles). Their calipers are painted charcoal gray and emblazoned with the inscription "Audi ceramic".
Typically Audi: Sharp lines and an elegantly curved roof
The wide, full shape of the R8 5.2 FSI quattro seems to hug the road. The brawny proportions and prominent wheel wells underscore its potential. The high-precision styling of the lines and the elegant curve of the roof are typical Audi features. A continuous contour optically connects the front, the wheel wells, the sides and the rear. Located well forward, the cab visually expresses the mid-engine design. The vertical air scoops (sideblades) on the sides are also indicative of the engine location. The massive aluminum gas cap is mounted flush within the right sideblade.
The design of the Audi R8 has already impressed experts, as evidenced by the double victory in the "World Car of the Year Awards 2008". In the ten-cylinder model, the styling has been sharpened up even more.
The front air inlets, which feed air to the coolers, and the lip of the front apron are painted in high-gloss black. The number of cross-braces has been reduced from four to two. The vanes of the single-frame grille have a striking chrome finish.
A very distinctive highlight of the R8 V10 are the all-LED headlights as standard equipment. Audi is the world's first automaker to use LEDs for the high beam, low beam, daytime running lights, and turn signals. Each headlight integrates 54 of these high-tech light sources. With a color temperature of 6,000 Kelvin the LED light closely resembles daylight, which is less tiring to the eyes in night driving. Further advantages of the LEDs include brilliant illumination, low energy consumption, and a virtually unlimited service life.
Special details also distinguish the body of the R8 V10. Its sideblades are more accentuated than in the eight-cylinder version. The side sills are more striking and wider; the exhaust grilles at the rear windows have a matt aluminum look. Through the large rear window, the ten-cylinder engine is clearly visible in its consummate technical beauty.
When in motion, this Audi high-performance sports car creates a downforce that keeps it in firm contact with the road - thanks to a rear spoiler which deploys automatically at 100 km/h and the fully enclosed underbody, which terminates in a sharply upward-curved diffuser. The dominant color at the rear end is high-gloss black, including the settings of the LED tail lights. The air outlets at the rear end also have only two cross-braces, and the exhaust system terminates in two large oval tailpipes.
Audi sets the example - in body weight and rigidity
The body of a sports car must be especially lightweight and rigid. Audi meets these requirements with the technology of the Audi Space Frame (ASF) and its high-tech aluminum construction. The body-in-white of the R8 V10, which includes an engine frame made of ultra-light magnesium, weighs only 210 kilograms (463 lb), and the quality of its lightweight design - the relation of weight to torsional rigidity - is the best in the sports car segment. The body is composed of profile extrusions, sheet aluminum and very complex gusset castings, all held together by 99 meters (325 ft) of welding seams, 782 rivets, and 308 special screws.
The interior of the R8 V10 provides a unique racing ambience at the luxury level. Its dominant element is the so-called monoposto - a wide arc that contains the steering wheel and the cockpit. As always in an Audi, the workmanship is of the highest quality. The surfaces of the dashboard and doors are lined with fine materials and adorned with precisely stitched decorative seams. Many customizing solutions are available: Audi supplies leather in a wide range of colors, packages with a carbon and piano-lacquer finish, or a made-to-measure luggage set. quattro GmbH, which has developed and is producing the R8 V10, also provides solutions for unconventional requirements.
The great everyday utility of the Audi R8 V10 is based in part on its spacious interior made possible by the long wheelbase of 2.65 meters (8.69 ft). Drivers and passengers of any size will always find a perfect sitting position. Visibility too is surprisingly good. Slender hinge pillars optimize the obliquely forward field of view. Another advantage for convenient everyday use is the luggage space: 100 liters (3.53 cu ft) fit under the front hood, another 90 liters (3.18 cu ft) can be stowed behind the seats. There is also room for two golf bags.
The Audi R8 5.2 FSI quattro combines its colossal performance with a generous complement of standard equipment. Highlights include heatable seat covers made of Fine Nappa leather, a driver information system, the navigation system plus and the Bang & Olufsen sound system along with deluxe automatic air conditioning and an alarm system. The instruments and the gearshift knob are decorated with red rings; the footrests and the rocker switches of the R tronic have an aluminum finish.
The list of options includes other highly attractive features - such as the Audi parking system advanced with its integrated rearview camera or numerous Audi exclusive customization options. Various leather packages provide a luxurious touch, while the bucket seats from the Audi exclusive program bring a highly concentrated racing atmosphere into the R8 V10.
The Audi R8 5.2 FSI quattro will be rolled out in Germany in the second quarter of 2009 at a basic price of EUR 142,400.

When Less is More: The Storied Success of Audi's 2.0 TFSI I-4 Engine
When leading trade publisher Ward's Automotive Group recently set out to recognize the world's 10 best automotive engines for 2009, one turbocharged four cylinder stood out. The Audi 2.0 TFSI I-4 won a place on the list for the fourth consecutive year.
The recognition validated a core strategy at Audi: That highly efficient engines can handily deliver the personality that discriminating premium luxury car buyers expect when they get behind the steering wheel. Central to this philosophy is an engineering orientation rooted in maximizing engine performance - whether that means fuel consumption or power and sportiness.
Over the past year, the U.S. luxury car market has started to break toward Audi's position on engine technology. As long as fuel prices remain volatile, luxury buyers are putting efficiency at the top of their shopping priority lists.
"There is an outmoded assumption that bigger is automatically better when it comes to engines powering the world's premier luxury models," said Johan de Nysschen, executive vice president, Audi of America. "In fact, we're watching the market begin to dispel that myth and put top-shelf value on efficiency. Audi's showing them they can gain that and not surrender the enjoyable aspects of motoring."
While the blend of efficiency and sportiness applies across Audi's engine lineup, the Ward's 10 Best Engines editors took note of the 2.0 TFSI I-4's significant improvements since winning a place in the rankings for 2008.
The newest Audi 2.0 TFSI engine produces substantial improvements over its predecessor by turning out 5.5 percent more horsepower (211 hp vs 200 hp) and a whopping 24.6 percent more torque (258 lb.-ft. vs. 207 lb.-ft.).
To put the new 2.0 TFSI I-4 engine's performance into perspective, consider that the engine used in the high-performance 2003-model-year S4 also achieved 258 lb-ft. of torque. But it did so with a V-6, bi-turbo configuration.
The new 2.0 TFSI I-4 first hit the U.S. market in the all-new A4 sedan and Avant models that went on sale this past fall. In the new A4, the updated 2.0 TFSI I-4 achieved 11 percent fuel-efficiency gains, making the A4 the most economical car in its class at the filling station.
Ward's selected its 10 best Engines from a list of 32 finalists. The nominees underwent two months of testing by Ward's editors. Ward's also requires the engines on the list to be available in regular-production, U.S.- specification models available for purchase no later than the first quarter of 2009 at prices no higher than $54,000.
