The Bugatti Chiron is the most powerful road car ever produced, with a quad-turbocharged, 8.0L W16 engine producing an insane 1,500 hp. The company promises a 0-62 time of under 2.5 seconds and a top speed of 261 mph, numbers helped along by the seven-speed dual clutch gearbox, multi-plate clutch four-wheel drive system, and carbon fiber monocoque.
