This is a clip of SSC Shelby Super Cars' (American) supercar/hypercar Ultimate Aero TT top speed testing in May of 2007. SSC did transmission temperature tests during these runs for its 2008 Ultimate Aero twin-turbo models. These tests have proven to be successful, and managed to hit 241.4 mph at 71% throttle.

By the end of August 2007, SSC was confident and invited The Guiness Book of World Records to officially record its top speed for the World's Fastest Production car held by the (Swedish) Koenigsegg CCR's 242 mph, and surpassing the unofficial (Italian/French/German) Bugatti Veyron's top speed of 253 mph. The high speed run in September was held in Washington State's predetermined "public" highway.

On September 13, 2007, the Ultimate Aero broke the World Top Speed record run at 256.15 mph on a 2 mile stretch of public highway in Washington State.

On October 9, 2007, The Guinness Book of World Records officially recorded the SSC Ultimate Aero as the fastest production car with a top speed of 256.19 mph (412.28 kph).

Because of the "S" bends and uneven pavement from the highway, the driver of the Ultimate Aero, 71 years old Chuck Bigelow (an auto enthusiast with no racing or testing background), says that there was more pedal to push. SSC will send an Ultimate Aero to Europe to test its true top speed on one of Germany's ultra-smooth test tracks.

The SSC Ultimate Aero also holds Road and Track's slalom record, previously held by the Ferrari Enzo.

SSC is also in the works for developing a 220+ mph ultra-luxury sports sedan to target "Guinness Fastest Luxury Sedan", set to debut in 2009.
