Here's a true battle of the giants: the new Pagani Huayra goes against one of the world's most powerful roadsters, the Bugatti Veyron Grand Sport Vitesse. Bugatti's Veyron Vitesse hides under its skin a 1,200 hp engine with four turbos and it can reach a top speed of 431,072 km/h (268 mph). The Pagani Huayra has "only" 700 hp and a top speed of 370 km/h. Even though it falls short in the power department, the Huayra remains a road-going piece of art.
