Quieter Spirit: Rolls reportedly planning hybrid Ghost for 15% better economy

If you've been pondering getting on the list for a Rolls-Royce Ghost but you're hesitant because of the negative environmental impact (and social standing) of the big, beautiful boat's V12 engine, we've got good news for you. British site Autocar is reporting that a hybrid version of the Ghost is in the works. It's rumored to be based off the mild hybrid system of the BMW ActiveHybrid 7, which makes sense considering that the two luxury sleds utilize the same platform. The nearly 18-foot long Ghost will likely still sport a 6.2-liter V12, but the brutish powerplant will be aided and abetted by a 20kW electric motor capable of an extra 15 hp and 155 lb-ft fitted into the baby Rolls' eight speed ZF auto transmission.

Battery power will reportedly come courtesy of a .6 W/h lithium-ion battery pack fitted to the Ghost's substantial trunk. The reported hybrid Ghost won't have the ability to run on battery power alone, but the luxury barge will employ start/stop tech and due to the battery's presence it won't need an alternator, either. The net result of the of the (relative) greenification of the Ghost will reportedly be a 15% bump in fuel economy.

A 15% efficiency bump probably won't do much to improve the Ghost's likely miserable fuel economy figures, but the added twist from the Ghost's electric motor may help it hit 60 mph more quickly than the gasoline-only 4.8 seconds (U.S. spec).

Sure, if this hybrid Rolls ever sees the light of day it'd make the already massive Ghost even heavier and more costly, but the negatives pale in comparison to the gratification of telling other rich people that your chauffeur drives a hybrid.
