18/4 Veyron Concept
The first Veyron, named after former Bugatti factory driver Pierre Veyron, debuted in Tokyo in 1999. The original concept's 6.3-liter, 18-cylinder engine put out 555 horsepower, had a top speed of 186.4 mph, and reached 60 mph in 5.3 seconds. Those numbers might seem like nothing compared to today's monster, but back then, this car was every bit powerful as its exterior, highlighted by the two protruding air intakes, was seductive. This was the fourth design study in a 15-month timeframe.
