Audi R8 2010

The most remarkable thing about the 2010 R8 isn’t its new 525-horsepower V10 engine — though it is quite remarkable — but that the R8 has lost none of its allure despite being two years old.

The tasteful appearance of the R8 (both inside and out), along with its mid-engine layout, outstanding road manners, prodigious comfort, and exceptional performance, rank it among the finest and most desirable production cars in the world.

The R8's new 5.2-liter V-10 descends from the collaborative design effort between Audi and Lamborghini, which yielded a 493-hp, 5.0-liter V-10 for the 2004 Gallardo. The 90-degree V-angle, selected to facilitate the sharing of block machining tools with Audi V-8 engines, results in uneven firing intervals. Boosting the displacement to 5.2 liters, installing direct fuel injection, and raising the compression ratio to 12.5:1 in the R8 yields 391 lb-ft of torque at 6500 rpm and 525 hp at 8000 rpm. A similar 5.2-liter V-10 in the Lamborghini Gallardo LP560-4 boasts slightly higher peak power and torque ratings.
