Following its debut at the Geneva Motor Show earlier this month, Rolls Royce has released details of the powertrain for the RR4 production version of its 200EX concept.

The new Rolls saloon will feature a unique 6.6 litre turbocharged V12 and eight-speed gearbox.

The production version of the car, which should remain faithful to the concept, will - despite its smaller engine - be more powerful than the larger 6.75 litre V12 powering the Phantom.

Rolls Royce says the new engine will produce upwards of 373kW ( 500hp). By comparison, the Phantom currently puts out 338kW (435hp).


Along with the new engine, a new eight-speed ZF automatic transmission will debut in the car, which Rolls Royce believes will significantly improve fuel efficiency and reduce CO2 emissions.

Rolls Royce CEO Tom Purves discussed details of the new drivetrain at a press conference in New York, where the 200EX is being shown to potential customers as part of a six-city world tour ahead of the production model’s official release later this year.


“RR4 will deliver an authentic Rolls-Royce experience to owners, so expect peerless comfort and build quality. However, we have consciously engineered this car to be more involving and dynamic for those owners around the world that will wish to drive it themselves,” Mr Purves said.

“There has been a great deal of interest in this car since we first talked about producing a new model series in the autumn of 2006 and the reaction 200EX received at its unveiling at Geneva was very positive. As we move another step closer to the start of production at Goodwood, it is exciting to be able to share some of the specific technical details with customers and the media.”

Further details of the RR4 will be released in the coming months before the car is launched.
