The R8 V10 Spyder is the convertible version of Audi 's mid-engined, 10-cylinder R8 supercar. As with its fixed-roof sibling, the R8 V10 Spyder is based on the same platform as the Lamboghini Gallardo and features an excellent balance of extreme performance and docile around-town driving manners. For those seeking a more affordable everyday exotic, Audi offers coupe and drop-top versions of the R8 with a V8. This 5.2-liter V10 engine delivers an impressive 525 horsepower at 8000 rpm, along with peak torque of 391 lb-ft at 6, 500 rpm. The sprint to 62 mph takes just 4.1 seconds, compared to just 3.7 seconds for the coupe R8 V10.
