While the GTC Speed has been around since August 2008, as well as the Flying Spur Speed saloon, their convertible sister is yet to receive the gift of speed from the Bentley geniuses. A prototype of the 2010 Bentley Continental GT has been spotted in the Nurburgring circuit in Germany during a test drive.

Okay, not so much has changed since we last saw it, but at a closer look, it has been given a more aggressive look courtesy of the mesh-grille and lowered intakes and height. Looking closer still, the steering wheel was given a new tri-spoke emblem with metallic accents as the rim bears a stitched leather design.

Like its older brothers, the 2010 GTC Speed will get a revamped 6.0L W12 twin-turbocharged engine. A new crankcase is also in order; much lighter camshaft and a speedier cam sensor are also added. Additional boost pressure also comes with the turbo engine.

The Speed models’ engine comes with 600HP and 553ft-lb of torque, accelerating at 0-100km/h in five seconds or less. The top speed should be around 300km/h.

Coming with the more aggressive look are new 20in wheels, redesigned bumper design, and a stiffer suspension. Nappa leather adorns the car’s interior, a 1,100W Naim sound system, and lots of chrome and wood design.
