Audi R8 5.2FSI Quattro

Audi R8 5.2 FSI Quattro this fall, one of the most technically savvy, visually stunning exotic sports cars in years will get even better.

On one hand, this V10-powered R8 is the product of know-how accumulated through Audi's string of victories in the Le Mans 24 Hour race, and the basis for a new sports-car racing program. On the other, the 2010 R8 5.2 FSI is a brand image builder intended to instill deep lust in car enthusiasts worldwide. We suspect there will be a waiting list for the limited number of R8 V10s headed for the United States, even at the anticipated base price of $195,000. That's about $80,000 more than the standard, V8-powered Audi R8.

The most obvious upgrade in the R8 5.2 FSI is its 5.2-liter V10 engine, with high-tech direct fuel injection and racing-style features such as dry-sump lubrication. The V10 generates 525 horsepower and 390 pound-feet of torque, or 100 horsepower and 73 pound-feet more the standard R8's 4.2-liter V8. It delivers 100.9 hp per liter of displacement, impressive for a non-turbocharged engine of its substantial size, with an 8700 rpm redline.

With the standard six-speed manual transmission or Audi's optional Sequential Shift Rtronic dual-clutch automatic and the R8's standard all-wheel-drive system, the R8 5.2 FSI accelerates from 0 to 62 mph in a scant 3.9 seconds. It hits 124 mph in 12 seconds, with a top speed of 196 mph. Yet, thanks to the R8's relatively light weight and efficient direct fuel injection, the V10 should deliver a combined EPA mileage rating of about 17 mpg. That's excellent for a true supercar.

The R8's aluminum superstructure is exceptionally rigid and light. Body panels are formed from aluminum and light-weight plastic composite, and fashioned to maximize aerodynamic downforce for stability at high speeds. Its underbody is fully enclosed, and an automatic rear spoiler deploys at about 62 mph to more firmly press rear wheels to the pavement as speeds increase. The R8 5.2 FSI will be distinguished from the standard R8 V8 by subtle styling tweaks, including larger side air intakes, more aggressive side sills and unique ten-spoke 19-inch wheels. It should also be the first car to use LED elements for all exterior lighting, including high- and low-beam headlights.

Given its rear mid-engine layout, the R8 V10 delivers a race-track friendly weight distribution of 44 percent front, 56 percent rear. Audi promises a race-car grade 1.2 g level of lateral acceleration. Yet the road going R8 5.2 FSI should deliver acceptable ride quality on the highway, thanks to an electronically controlled suspension that automatically adjusts shock-absorber rates depending on how the car is driven. Audi will also offer high-tech ceramic-composite disc brakes. They're about 20 pounds lighter than conventional iron discs, and Audi claims they have a service life of 185,000 miles.

Inside, the R8 5.2 FSI delivers Audi's typically pleasing interior design, finished in a richer, more tailored fashion than the typical A4 sedan. The car offers a host of options in trim materials and upholstery to allow owner customization. The standard-equipment list includes heated Nappa leather seats, a driver information system, a navigation system and premium Bang & Olufsen audio. Options include a park-warning system with back-up camera.

The R8 offers an impressive amount of luggage space for a car of its type. Its mid-engine design allows separate storage boots front and rear, and Audi claims both will hold a standard-size golf bag.

The V10-powered R8 is the road-going version of a race car Audi is building for international GT3-class sports car racing, and it will compete with makes such as Porsche and Ferrari. That will only increase its appeal among well-heeled car enthusiasts. When the R8 5.2 FSI hits showrooms sometime this fall, there could be more potential buyers than cars, despite tough economic times and the projected $195,000 sticker price.
