The Best Car at the Detroit Auto Show?

The Best Car at the Detroit Auto Show?

"The Audi R8 5.2 FSI quattro was my pick of the first day at Detroit," writes Noel McKeegan from the North American International Auto Show which opened today. "It was the most aesthetically striking car that wasn't a concept, and with the 525 hp 5.2 liter V10 engine replacing the 420 bhp 4.2 V8, performance has gone another level. With the quattro all-wheel drive, LED-headlights and aluminum body with a very curvaceous rear end treatment, it really is a knockout."

"The key figures are that the V10 makes 105 more horses than the 4.2-liter V8 R8, 78 more foot pounds of torque, gets to 100 kmh in 3.9 seconds and has a top speed of 316 km/h."

Audi's press release follows:

Ingolstadt—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.
