The first automobile ever produced was the Benz Patent Motorwagen, built in 1885 and unveiled in 1886 by Karl Benz. Unique and consequently the fastest, it established a record speed of 16 km/h (10 mph). More than a century later, in September 2007, the SSC Ultimate Aero TT registered the latest record, for a production car, of 412 km/h (256.18 mph). The history of the world's fastest mass produced, street-legal cars has been improving over time with SSC Ultimate Aero TT reaching speeds of up to 256 Mph.
