The SSC Ultimate Aero is an American-built mid-engine supercar by Shelby SuperCars. Its higher-performance limited production version, the SSC Ultimate Aero TT, is the fastest production car in the world, with a recorded speed of 256.18 mph (412.28 km/h). This speed was achieved during tests on September 13, 2007 in West Richland, Washington, United States and verified by Guinness World Records on October 9, 2007.
The Aero and the Shelby SuperCars company are the brainchildren of Jerod Shelby (no relation to car designer Carroll Shelby), who started out building exotic “replicars” including a Fiero-based Ferrari F355 replica and a Lamborghini Diablo replica based on a spaceframe which later was used in the Ultimate Aero prototype. Jerod later moved from building replicas to designing the first true Supercar and after seven years it finally began to take shape. Although the basic Aero model is no longer produced, the Ultimate Aero is still in production with an MSRP of around $654,400.
