New 2013 Bentley Continental GT Speed Convertible: Official

The Bentley Continental GT Speed Convertible, the drop top version of the GT Speed, has been officially revealed ahead of a Detroit Auto Show debut. Just as expected, Bentley has transplanted all the goodies from the latest version of the GT Speed in to the GTC Speed, which means a fulsome 616bhp and 590lb/ft of torque from the delicious 6.0 litre W12 and, despite gaining more than 200kg to keep the huge Bentley stiff without its roof, the GT Speed Convertible manages to hustle to 62mph in 4.1 seconds – just a tenth slower than the tin-top Speed. That extra lard does have more impact as you head towards 100mph with the convertible taking 0.7 seconds more, but there’s not exactly a paucity of power on offer.

But here it is, and it’s going straight on sale. Having waited almost until the end of the 997’s life before launching a 911 GTS, this latest GTS is arriving much earlier in the 991’s lifecycle than you’d expect.
