Bugatti Veyron W16: Okay, we know it's not a V8, but the W16 is essentially a pair of narrow-angle 4.0-litre W8s Siamesed for speedball ecstasy - and another prime example of the eight-s versatility and power potential. This W16 monster runs four turbos, 10 radiators, four camshafts and 64 valves, delivering 736kW (1001PS) and a 1250Nm avalanche from 7993cc. It drives all four wheels via a seven-speed DSG gearbox for an officially verified top speed of 408km/h. The Bugatti
Veyron is a technological miracle that many thought was unachievable right up until its 2005 launch.
