Powered by a Ghost
The Dawn is propelled by a 6.6-liter twin-turbo V-12 that is lifted pretty much intact from the Ghost II, making the same 563 horsepower at 5250 rpm and 575 lb-ft of torque at just 1500 rpm. The transmission is the same “satellite-aided” eight-speed unit found in the Wraith that will use the GPS to prepare for upcoming hills and curves and select the proper ratio. As for performance, Rolls expects the Dawn will hit 60 mph in 4.9 seconds, while top speed is limited to 155 mph.
