Porsche presents at The Quail, A Motorsports Gathering a customized 911 GT3 RS by the GT Model Line and Style Porsche as a tribute to the 1972 911 Carrera RS 2.7. Its 4.0-liter naturally aspirated boxer six-cylinder engine generates 518 hp, and revs to 9,000 rpm. That power is routed exclusively to the rear wheels via a seven-speed PDK dual-clutch automatic transmission. Making extensive use of motorsport-derived aerodynamics, it generates more than 900 lbs. of downforce at 124 mph and 1,895 lbs of downforce at 177 mph.
