Why it matters

The Ultimate Aero was the car with which SSC (Shelby SuperCars) set a world production-car speed record in 2007, taking the title from the Bugatti Veyron. The SSC site gives a tested top speed of 257.41 mph for the twin-turbo TT, and SSC retired the model with a last five-car XT edition.

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

SSC listed the Ultimate Aero in several engine stages: a supercharged 382 cu in V8 with 787 bhp (8 psi) and a 1,046 bhp version (14 psi), then the twin-turbo TT with 1,183 bhp. In 2007 SSC closed a 12-mile stretch of Highway 93 in Elko County, Nevada for a record attempt against the Veyron's 253 mph. The TT was planned in a run of 24 over about two years, and a first car was auctioned on eBay.

In 2012 SSC announced the retirement of the Ultimate Aero with the 2013 Ultimate Aero XT, a run of five cars using a 1,300 hp version of the Tuatara engine and the seven-speed Tuatara gearbox. After those five were sold, production was to end for good.
