Power comes from an uprated version of the standard car's 6.0-litre W12 petrol engine. It develops 616bhp (a 49bhp increase) and 590lb ft of torque (a 74lb ft increase).
Drive goes to all four wheels, through a new close-ratio eight-speed automatic gearbox. Bentley quotes a 0-60mph time of 4.0 seconds (0.4 quicker than the standard car) and a top speed of 205mph.
The 205mph Bentley Continental GT Speed coupe blasts from 0-60mph in just 4.0 seconds
A lowered ride height and tweaked steering and suspension are aimed at giving sharper handling.
Exterior changes are limited to bespoke 21-inch alloy wheels, dark-tinted air intakes and a 'rifled' finish for the exhaust tailpipes. The cabin features upgraded materials.
The Continental GT Speed is available to order now, at 151,100 a 14,390 premium over the standard model. First deliveries are expected in October 2012.
