The SSC Ultimate Aero TT,[1] is currently the fastest production car in the world, with a fastest recorded speed of 413 km/h (257 mph).[2] This speed was reportedly achieved during tests on September 13, 2007 in West Richland, Washington, United States and verified by Guinness World Records on October 9, 2007.[3] At a two-way average speed of 257 mph, the SSC Ultimate Aero is actually faster than a $1.5 million Bugatti Veyron, which has been clocked at 253 mph. And at about $650,000, its a lot less expensive. Updated Armed with the more powerful new engine, the 09 Ultimate Aero will be able to reach world-record speeds of 270 MPH, raising the benchmark for supercars and pushing the limits of current production car technology. After holding the Worlds Fastest Production Car for the past year, the Shelby SuperCars Ultimate Aero is receiving several refinements for the 2009 model year. The SSC engineering team equipped the 2009 Ultimate Aero with a 15% increase in horsepower, a revamped front fascia design, and an array of important interior upgrades. The most substantial change is an SSC-designed, 1-piece billet aluminum engine block. A milestone for the limited-production automobile manufacturer, the new block improves structural integrity and oiling capabilities allowing SSC to boost the power output to 1287 horsepower while improving durability
