Ford introduced a redesigned 2005 model year Mustang at the 2004 North American International Auto Show, codenamed "S-197," that was based on the new D2C platform. Developed under the direction of Chief Engineer Hau Thai-Tang, a veteran engineer for Ford's IndyCar program under Mario Andretti, and exterior styling designer Sid Ramnarace, the fifth-generation Mustang's styling echoes the fastback Mustang models of the late-1960s. Ford's senior vice president of design, J Mays, called it "retro-futurism." The fifth-generation Mustang was manufactured at the Flat Rock Assembly Plant in Flat Rock, Michigan. Engines were revised for 2011. GT models included a 32-valve 5.0 L engine (4951cc or 302.13 cu. in.) (also referred to as the "Coyote".) producing 412 hp and 390 ft-lbs of torque. Brembo brakes are optional along with 19-inch wheels and performance tires.
