BENTLEY has revised its high-performance Continental GT Speed raising the bar even further in terms of exclusivity and performance.

The GT Speed is the fastest production Bentley ever with a top speed of 206 mph and now it delivers even more power and torque, while a striking new Black Edition model will also be joining the Speed family.

Bentley's ngineers in Crewe have developed even more muscle from the Continental's 6.0-litre twin-turbocharged W12 engine taking power up to 642bhp - up from 635bhp.

As a result, the 0-60mph sprint time has dropped to just 3.9 seconds from 4.1.

The Continental GT Speed Black Edition is available in both coupe and convertible body styles and the choice of body colour is complimented by a high gloss black finish to the exterior brightware, including the window openings and lamp bezels.

All-black 21-inch five-spoke wheels cover distinctive brake callipers, which can be specified in red or black finishes.

The Black Edition also features contrast colours to the front splitter, side skirts and rear diffuser in four different shades and customers can also choose to colour-match the door mirrors as a final exterior accent.

Paul Jones, product line director for the Continental GT, said: "We have developed the GT Speed Black Edition to meet demand from customers for a model in the Continental line that offers both increased sporting capabilities and instantly recognisable styling cues."

Prices for the GT Speed currently run from £168,000. First deliveries of the new models are scheduled for this summer.
