what you see here is not just a Continental Coupe with a top sliced off – it is the 2013 Bentley Continental GT Speed Convertible, a open-top performance flagship from the UK marque that happens to be the world’s fastest four-seat convertible with a top speed of 325 km/h (202 mph). lurking behind the matrix radiator grille is a 6.0-liter twin-turbo W12 petrol unit, pumping out a mind-blowing 616 horsepower (459 kW) and turning out a peak torque of 800Nm (590 lb-ft) at 2,000 rpm. this awesome power is transmitted to all four wheels via a close-ratio ZR eight-speed automatic transmission while stopping power comes from large ventilated discs all-round. the impressive figures enable this 2.5 ton (5,500 lbs) drop-top beauty to make 100 km/h (62 mph) from standstill in just 4.4 seconds and 160 km/h (100 mph) in mere 9.7 seconds. sporting muscular lines born out of contemporary hand craftsmanship, the Bentley Continental GT Speed Convertible promised both performance and luxury – qualities that are second nature to Bentley which we shouldn’t even have to mention. anyway, other features include 21-inch allow wheels that are unique to this model, dark-tint grilles, rifled exhaust tail pipes, a class-leading torsional stiffness (22,500 Nm/degree, if you really need to know), a lower and beefier suspension setup, a subtle but functional bootlid spoiler, handcrafted cabin that includes distinctive diamond-quilted hide upholstery and a complete infortainment system, and the Mulliner Driver Specification comes standard with this GT Speed Convertible. the Bentley Continental GT Speed Convertible will make its global debut at the 2013 Detroit Auto Show which also means information with regards to pricing and availability is not readily available at this point in time but in the mean time, you can satisfy your curiosity with the gallery below.
