2011 Rolls-Royce Ghost – Click above for high-res image gallery

Rolls-Royce unveiled the production version of its new "smaller" car, the Ghost, at the Frankfurt Motor Show and it goes into production next year. AutoCar is now reporting that the Rolls engineers are working on a hybrid version of the Ghost using BMW's mild hybrid system. The mild hybrid is getting its first application in a BMW right about now in the new ActiveHybrid 7. The Ghost shares most of its platform with the new 7-series, so installing the electric assist should be a no-brainer. The main difference is that the BMW pairs the electric motor and battery with the 4.4-liter twin-turbo V8 while the Roller would retain its 6.2-liter V12. AutoCar estimates the Ghost hybrid would boost mileage by up to 15 percent, which might be a stretch but in a car of this type every little bit helps. The 20 kW motor is sandwiched between the engine and transmission and can't drive the car purely on electricity. It does provide start-stop capability and reduces parasitic losses by using regenerative braking to supply some of the electrical needs of the car.
