The Continental Supersports Convertible further strengthens Bentley’s range of luxury performance cars, following the introduction of the Continental Supersports Coupé in 2009. The new Supersports Convertible, with the same 630PS (621bhp/463kW) twin-turbocharged W12 engine, is the fastest, most potent drop top Bentley has ever built, offering the ultimate Bentley driving experience in a dramatic convertible profile.

The inspiration for the ‘Supersports’ name is the 1925 Bentley Supersports, a race-bred version of the iconic Bentley 3-litre, that delivered 85bhp when more ordinary cars were equipped with a modest 15bhp. It was also the first production car to reach 100mph – extreme performance in its day.

The new, muscular four-seat Supersports Convertible is unmistakably Bentley in its design and craftsmanship but its interior signifies a dramatic re-interpretation of Bentley luxury. Satin-finished carbon fibre, Alcantara and ‘soft grip’ leather create a unique ambience with a distinctly sporting and contemporary style.

All models in the Continental model range, including the new Supersports Convertible are now capable of running on both petrol (gasoline) and E85 bioethanol or any combination of the two, reaffirming Bentley’s ongoing commitment to make all its cars bio-fuel compatible by 2012. Pioneered by the Supersports Coupe, this FlexFuel technology offers a reduction of up to 70 per cent in CO2 emissions on a ‘well-to-wheel’ basis, a measure of a fuel’s net contribution to the atmosphere, not just tailpipe emissions.

To ensure seamless power delivery, the on-board fuel supply system detects the blending ratio of the fuel in the tank and ensures that power and torque remain constant regardless of the ratio of petrol to biofuel.

The Supersports Convertible is capable of 0 – 60mph in 3.9 seconds and 0 -100mph in 9.6 seconds on its way to a top speed of 202 mph. It shares its ride height with the GTC Speed, sitting 10mm (0.4in) lower at the front and 15mm (0.6in) lower at the rear than the standard GTC.

Carbon ceramic brakes are standard fitment and provide a reduction in rotating and unsprung mass of 20kg (44lb) from the front axle, benefiting steering response, grip and ride comfort. The large diameter (420mm front, 356mm rear) lightweight discs and eight-piston calipers offer fade-resistant braking performance with minimal disc distortion under high thermal conditions.

Pricing will be announced nearer to the car’s launch in the autumn, and the Supersports Convertible will be officially revealed at next month’s Geneva motor show.
