Bentley has revealed details about its new Continental GT Speed ahead of the Moscow Motor Show.
The new model comes with a 6.0-litre twin-turbo W12 with 616bhp and now features fuel economy of 19.5mpg and CO2 emissions of 338g/km.
Efficiency has been improved by 12% with help from a new close-ratio eight-speed automatic transmission, designed to keep the engine operating in its most efficient state.
The previous model could only manage 16mpg and put out 410g/km CO2. The Continental GT Speed can hit 0-60mph in 4 seconds and top speed is 205mph.
More details will be revealed at the Moscow Motor Show.
