Detroit motor show 2009 - Bentley GTC Convertible Speed

If you're the sort of person who wonders what it's like to drive along with the wind in your hair at close to 200mph then a) we presume you don't wear a toupee, and b) you had better make a bee-line for your nearest Bentley dealer.

Bentley recently announced that it will introduce a Speed model to compliment the face-lifted GTC Convertible Speed that has gone on sale this year.

The Speed has 600bhp, which is 48bhp more than the standard car. That means it can hit 200mph with the roof up, and 195mph with it down. It takes 4.5sec to travel from 0-60mph – 0.3sec quicker than the standard model.

The Speed also has lowered and modified suspension to improve the handling, while the stability control system has a Dynamic setting, which cuts in later and allows the driver to exploit the engine to the full

The standard car also features a new stability control mode, called Sport Traction, which improves handling on loose surfaces.

The standard car costs £129,700, benefiting from the recent VAT cut to be £2800 less than the previous model. The GTC Speed costs £146,100.
