Audi R8 5.2

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 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) thats 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: its 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 doesnt 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).

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 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 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 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.
