The 997 Turbo's twin BorgWarner VTG turbochargers were a first for a Porsche production car. Its engine is based on the 911 GT1's design and makes 473 horsepower and 457 lb-ft. Porsche put the 911 Turbo Cabriolet on sale in September 2007, with performance close to the coupe. This one is a 2008 911 Turbo Cabriolet in black over a black interior. It has carbon trim on the steering wheel, hand brake, dash and gear selector.
