At 220mph, the speedo stops climbing, yet a gauge indicates the unit is delivering only 90 per cent of its full potential. That's because we're at 3,300ft above sea level, where there's simply not enough oxygen to burn all the fuel being gulped by the cylinder heads for the 252mph Bugatti to reach top speed. Yet, travelling nearly as fast as a McLaren F1, the car is stable, due to the adjustable aerodynamics and suspension. Wind and road noise roar through the cabin, but there's still a surreal quality to the serene manner with which the Bugatti covers the ground at such devastating speed.
