WORD'S FASTEST CAR?

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 mph (411.99 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 SSC Ultimate Aero does not have electronic aids like ABS brakes or traction control.

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 his first 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 $650,000.

SPEED
SSC tested the top speed capability of the Ultimate Aero TT on March 22, 2007. The original test was scheduled for March 21, 2007 but was called off due to bad weather conditions. SSC closed down a 12-mile (19 km) stretch of U.S. Route 93 in Nevada for the event. Their goal was to replace the Bugatti Veyron as the fastest production car ever produced, which at the time could achieve 253.7 mph (408.3 km/h). Simulation and testing at NASA's Virginia facility had shown that the Ultimate Aero TT is theoretically capable of approximately 273 mph (439 km/h).[16] The March 22nd attempt failed to break the record, due to sub-optimal conditions. Test driver Rick Doria reported "wheel-spin" at speeds above 190 mph (310 km/h).[17] Despite the failure of the attempt, the car still reached 242 mph (389 km/h).

SSC announced they had broken the speed record for the world's fastest production car with 256.18 mph (412.28 km/h) in West Richland, WA on September 13, 2007. The reported record speed came from an average of two runs in opposite directions, in accordance with Guinness Book of World Records rules. The first run clocked 257.44 mph (414.31 km/h) and the return trip 254.91 mph (410.24 km/h). The results of this test, verified by Guinness World Records on October 9, 2007, gave the SSC Ultimate Aero the title of world's fastest production car, with a top speed of 256.12 mph (412.19 km/h).[18] This beat the previous record holder, the Bugatti Veyron, that has a top speed of 253.81 mph (408.47 km/h).

In addition to the fastest production car record, SSC also applied for the world record for the highest horsepower for an emissions-legal production automobile.[1]

The record-breaking 2007 Shelby SuperCars Ultimate Aero Chassis #TT-02 was later put into auction by Shelby SuperCars, which also included SSC World Record commemorative watch, key fob, original record-breaking wheels and tires, framed official Guinness World Records certificate with commemorative photo signed by Shelby SuperCars team.[19]
