The 2013 Bentley GT Speed Convertible is the topless version of the British brand's flagship coupe. Dubbed the world's quickest four-seat convertible, the Bentley GT Speed Convertible features all-wheel drive, an eight-speed automatic transmission, and a 12-cylinder engine that pushes out 616 horsepower thanks to the efforts of twin turbochargers.
