#12: Aston Martin Valkyrie

A collaboration between Aston Martin and Red Bull Racing Advanced Technologies, the Valkyrie brings Formula 1 technology to the road, with only 150 road coupes planned. Its heart is a screaming, naturally-aspirated 6.5-liter Cosworth V12, complemented by a hybrid system for over 1,160 hp. Extreme aerodynamics and a lightweight carbon fiber structure define this radical, road-legal race car.
