Lexus RC F Coupe fully unveiled ahead of Detroit (pictures)

The IS-based Lexus RC F Coupe has been unveiled early in anticipation of the 2014 Detroit auto show next week. We expect the RC to carry a 2015 model year.

The muscular RC F features flared fenders at all four corners wrapping the coupe's 19-inch forged aluminum wheels.

The cabin, predictably, looks a lot like the IS sedan's, but this model debuts a "Lexus-first elliptical cross-section thick-grip steering wheel with optimum placement of paddle gear shifts," according to the automaker's release. Ideally, the new wheel should fit better in the driver's hand.

The coupe's high back seats feature embossed "F" logos on the headrests and are available in one of five different leather trim colors, each with contrasting stitching.

Instead of Lexus' Remote Touch Controller, the RC F appears to have a small touch pad. Could this be the end of Lexus Remote Touch or just the next evolution?

A motorized spoiler on the rear deck rises at speeds of 50 mph and above to enhance high-speed stability and retracts when traveling below 25 mph for a clean look.

These fender vents behind the front wheel had me convinced that the RC could debut with an IS-F badge.

Lexus has finessed the IS sedan's front light clusters. They now appear to integrate better with the L-shaped LED indicator lights. The headlamps themselves appear to be fully LED illuminated.

The tail lights wrap around the corners of the vehicle.

The hood sits higher than the IS sedan's to accommodate a hood vent and a larger engine.

Lexus tells us that the RC-F will be powered by a V-8 engine. We're assuming that it's the same 5.0-liter V-8 that powers the current IS-F sport sedan. Stated power should be at least 416 ponies.

Rather than just shave two doors from the IS' profile, the RC F Coupe features a revised roofline that slopes more aggressively.

We're also guessing that the power will flow to the rear wheels via the automaker's eight-speed Sport Direct-Shift automatic transmission.

Available carbon fiber F Sport components will allow drivers to customize their ride.

We expect to learn more about the RC F Coupe at the 2014 Detroit auto show next week.
