Expected to sit on the Rolls-Royce lineup as the smallest, most “affordable” model yet, the Rolls-Royce RR4 has once again made the headlines with the revelation of its engine specs. Unveiled in concept form as the Rolls Royce 200EX at the Geneva Motor Show earlier this month, little production information was given on RR4, leaving many of the more pertinent details up to heavy speculation (which we auto bloggers are very, very good at).

Apparently deciding to throw us a bone, Rolls-Royce CEO Tom Purves resolved one of our most burning questions today by announcing that the new Rolls-Royce RR4 will be powered by BMW’s 6.6L turbocharged 12-banger. Mated to the same 8-speed ZF gearbox found on the Phantom, the RR4 will be capable of producing well-over 500bph (upwards of 373kW/507PS), allowing it to stand toe-to-toe with it’s big brothers. Misleadingly referred to as the “baby” Rolls, Rolls-Royce CEO Tom Purves stressed that there’s nothing minimizing about the RR4, especially in terms of performance. “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.”
