The world's first automobile, the Benz Patent Motorwagen, was unveiled in Mannheim, Germany, in 1886. Made of steel tubing and wooden panels, this Karl Benz creation had three wheels, a rear-mounted engine and a whopping top speed of 10 mph. Oh, have things changed in the last hundred or so years. Steel and wood have been replaced by lightweight carbon fiber and Kevlar, and aerodynamics and automotive engineering have become serious fields of research, all in the effort to go faster and faster. Two dozen autos have claimed the mantle of world's fastest street car since the Motorwagen made its debut, with the current record holder capable of a mind-blowing 257 mph. To satisfy your need for speed, here are the 10 fastest street cars of all time.
