The Veyron features a W16 engine—16 cylinders in 4 banks of 4 cylinders, or the equivalent of two narrow-angle V8 engines mated in a "W" configuration. Each cylinder has 4 valves, for a total of 64, but the narrow V8 configuration allows two camshafts to drive two banks of cylinders so only 4 camshafts are needed. The engine is fed by four turbochargers, and it displaces 8.0 L (7,993 cc/488 in³) with a square 86 by 86 mm bore and stroke.

Bugatti Veyron, seems to have 2 engines, guess its a pile of crap then.

I mean who cares that it has over 1000bhp and can do over 250mph, untill it can do it with a single v16 engine it can keep on walkin.
