After holding the "World’s Fastest Production Car" title 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.
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. In order to accommodate the '09 Ultimate Aero's unique fuel system requirements, SSC turned to American company Aeromotive to develop a flawless system. The aggressive nose is redesigned with enhanced aerodynamics to accommodate the 2009 Ultimate Aero's higher top speed, and carbon fiber louvers on the side intakes draw in an additional 20% of air into the radiators for improved cooling. The improvement in overall performance will widen the already sizeable gap between the Ultimate Aero and its competitors.
