:::SSC Ultimate Aero:::

The Ultimate Aero was built by Shelby Super Cars to rival the Bugatti Veyron as the fastest production car in the world. The Aero succeeded in this and as of October 2007 is the latest car to hold the position as the worlds fastest production car!! The Aero has a top speed of 412.233 km/h (256.15 mph) and a re-adjustment of the transmission makes it possible to reach speeds of 437 km/h (although a run at that speed hasn't been done yet).

:::Saleen S7:::

The Saleen S7 is considered to be America's first production certified supercar and is the first car made by Saleen that is not based on the design of another car (for example the Saleen Mustangs - based on the Ford Mustang). The S7 can accelerate from 0-60 mph in 3.4 seconds and the top speed is above 322 km/h (200 mph). The orignal was replaced by a twin-turbo version in 2005. The S7 was also the very first car to be completely developed digitally.
