“There is no substitute.” Most every automotive enthusiast can tell you which company uses that phrase, but they can also tell you that every year there are new contenders intent on proving otherwise. Porsche sees itself as the top dog (as do countless fans of the brand), and to remain at the top it must continue to build outstanding products, products that shoppers truly can find from other manufacturers. The 911 GT3 satisfies that requirement by offering a six-cylinder engine with an eye-popping 415 horsepower (sans turbo or supercharger assist), reduced weight and ride height for improved handling, and a style that is uniquely Porsche. There may be other sports cars and supercars, but the GT3 proves, there is no substitute.
