Imagine a 400-horsepower, all-aluminum V8 inside a 2+2 coupe so muscular it appears to be shrink-wrapped. Imagine the handling of a competition-inspired suspension and brakes that you control from an interior awash in aromatic leathers and brushed nickel. Now, imagine it all wrapped in a concept so powerful that it is still the only one of its kind 40 years after its incendiary inception. Designed to redefine performance for another generation and to set the industry on its ear all over again. The 2006 GTO. Designed for Action.
