This is a story of four charismatic engineers and one near-mythic number. First, the number: 1,000 horsepower. That is the power of the Bugatti EB 16.4 Veyron, an output that surpasses all road cars by such a margin that it looks like a misprint. But no, with the aid of four turbochargers, the Veyron's 16-cylinder, eight-liter engine manages the power of, say, two Dodge Vipers. Or nine base-model Honda Civics. The car seats two.
