The new RC is an aggressively styled sports coupe with seating for four. Essentially a coupe version of the IS sedan, it uses a standard 3.5-liter V6 engine hooked up to an eight-speed automatic. An all-wheel-drive version is available with a six-speed automatic. Top-trim RC F versions, fitted with a 467-hp, 5.0-liter V8, target the BMW M4. That prodigious output is routed to the rear wheels with a torque-vectoring differential, which sends power to the wheel that has the most grip. The RC F is super-quick, with a loud exhaust bark. The various driving modes sharpen throttle and steering response, but the car's weight ultimately compromises agility.
