After much anticipation, Rhys Millen Racing has finally unveiled its mid-engined V8-powered Genesis Coupe at the 2009 SEMA Show. The RMR460 gets its name from the powerful Tau 4.6-liter V8, that has been borrowed from the Genesis Sedan. But RMR wasn’t satisfied with leaving the engine stock, instead choosing to upgrade the engine’s internals (with things like JE pistons) ad a set of eight individual throttle bodies for optimum throttle respponse and power. Output is rated at 500-hp!

Finally, a new transmission was needed to get all that power to the rear wheels and for that RMR went to Mendeola for a five-seed sequential box that allows the car to reach a top speed of 182 mph!

Additional modifications include an RMR Signature Edition Kit, a carbon fiber rear spoiler and rear hatch, Sparco seats and 20-inch HRE 560 series wheels, with some big 285/30/20 rear Toyo T1R tires.
