Rolls-Royce Motor Cars have announced the official name for the model only known as the new Rolls-Royce RR4 so far, previewed as the 200EX Concept early this year. The new car will be called the Rolls-Royce Ghost, in a similiar naming theme with its bigger brother, the Phantom.

Also released with the announcement are some updated specs. The 200EX Concept had a V12 engine (no other details) and a 6-speed auto. The final Rolls-Royce Ghost production car will have a 6.6 liter turbocharged V12 – that’s up 0.6 liters from the 6.0 liter unit in the BMW 760i.

Like the 760i, it will be mated to a ZF 8-speed automatic, and while Rolls-Royce says the 6.6 liter will produced over 500 horsepower, it may very well be closer to 600 since the 760i already makes 544 horses.

Dimensions-wise. the Ghost will measure 5399mm long, 1948mm side, and 1550mm tall with a wheelbase of 3,295mm. That’s a good measure longer than the F02 LWB 7-Series 3,210mm wheelbase, but shorter than the Phanton’s 3,571mm and the Phantom Coupe’s 3,320mm.
