Introduced in 2006, the R8 Coupe 4.2 Quattro was based on the design of the Audi Le Mans Quattro concept car, sharing the same chassis of the Lamborghini Gallardo. For the 2009 model, the coveted 525 HP 5.2L V10 was added by Audi. In 2012, Audi put forth a slightly redesigned version of the R8, along with the R8 GT, a lightweight, racing-oriented 560 HP version of the 5.2L V10. Along with the performance upgrade, the GT featured weight-saving carbon fiber throughout the interior and exterior. In the most recent generation of the R8, the coveted V10 engine remains, making it one of our top picks in the world of supercars.
