BENTLEY has revealed its fastest and most powerful four-seat luxury motor ever in the shape of the 209mph Continental Supersports which can hit 60mph in just 3.4 seconds.

And there is an open-top on the way too which is no slouch either with a top speed of 205mph and a sprint time from standstill of just 3.7 seconds.

That joins the high performance club as world's fastest four-seat convertible.

Power for the new models comes from Bentley's mighty 700bhp W12 engine redeveloped for the Supersports with new high-performance turbos and engine hardware.

The cars also have a torque vectoring system to maximise traction.

Key to the new Supersports' power increase over the outgoing model are the newly designed, higher-capacity turbochargers and a revised charge-air cooling system which create more boost and additional power.

The engine revisions result in an increase of 79bhp from the 2009 Supersports model - a 10 per cent power-to-weight improvement. The top speed rises by five miles per hour and CO2 emissions come in at 358g/km.

Fuel consumption is expected to be no more than 18mpg on a combined run.

To increase stopping power the new Supersports is fitted with high-performance carbon ceramic brakes - the largest of their type fitted to any car so far.

Bentley says the performance of the Continental Supersports is matched by an upgraded handling system with a specifically calibrated version of the torque vectoring system first introduced on the Continental GT3-R.

The Continental Supersports retains the Bentley all-wheel-drive system, sending 60 per cent of the engine's power to the rear wheels for a more balanced and sportier character.

As far as exterior design goes the Supersports comes with a new sculpted front and rear bumper design incorporating a carbon-fibre splitter and diffuser, new side sill extensions and bonnet vents, dark-tint headlamps and tail-lamps, and a complement of black-finished brightware to the front grilles, lights, rear bumper, door handles and window surrounds.

There is also an optional rear spoiler and front splitter.

The new Supersports Convertible comes with a multi-layer hood and a neck warmer for days out in early spring and autumn.

Wolfgang Durheimer, chairman and chief executive of Bentley Motors, said: "The Supersports name is legendary at Bentley.

"From the very first Supersports of the 1920s, to the Continental Supersports of 2009 - and now with the third iteration of this iconic model - it is a name which excites, impassions and thrills. Only Bentley could create a car which blends immense performance and unrivalled luxury in this way."

The new Bentley goes on sale later this year and can be expected at a price pushing close to £200,000.
