Of all super cars, the R8 is undeniably the most elegant, most fun to drive and most versatile thanks to its quattro AWD. Not only that, but it’s available as a coupe or cabriolet, the latter being just as attractive with the roof up or down. The less expensive model is equipped with a 4.2L V6, while the more athletic 5.2 is powered by a 525-hp V10. Finally, the GT gets a 560-hp engine.
