"It&amp;#039;s no secret that the 4-door Genesis sedan and 2-door Genesis coupe share some underpinnings to allow for their common rear-wheel-drive architecture. So when we first heard the engine choices for both cars, we were puzzled as to why there was no V-8 engine choice for the coupe.   Granted, some of us didn&amp;#039;t give it a second thought, and never really considered the Genesis coupe a serious sports car. But Rhys Millen had other ideas. While supercharging, as in the Hurricane Genesis, might be right for some, RMR went for a natural enhancement by shoehorning the Tau V8\u2014an engine originally found in Hyundai&amp;#039;s Genesis R-Spec sedan\u2014into the coupe. Fitted with an AEM engine management system, a titanium-tipped stainless- steel exhaust system and better cooling thanks to an oil cooler, this Tau produces 450 horsepower. Power reaches the rear wheels via an RMR clutch and flywheel and the stock 6-speed manual transmission. The differential is also cooled to ensure durability.        Hyundai Genesis RM500    As is typical of any RMR creation, the road-holding capability was also increased, but the suspension is kept stock. Hankook RS-3s, in size 245/40ZR-19 up front and 275/35ZR-19 out back, ride on 19-in. HRE 793-RS wheels, while Brembo carbon-ceramic rotors are squeezed by 6-piston calipers up front and 4-piston units in back.   The reasoning behind keeping the suspension stock is simple: Rhys wanted to make this potent Genesis as close to an actual production car as possible. Of course, it doesn&amp;#039;t help that the full RMR carbon body kit\u2014comprised of front lip spoiler, side skirts, rear diffuser, 3-piece spoiler, grille, roof overlay and brake duct panels\u2014sets it visually apart from any stock Genesis coupe. On the inside, Sparco race seats and an RMR suede package round things out.        Hyundai Genesis RM500    The obvious question is this: Will we ever see such a car in production form? Although it&amp;#039;s doubtful that the Genesis coupe will ever get a V-8 powerplant, the Genesis RM500 was designed to gauge reaction from both the public and the manufacturer. As such, that is what will dictate the fate of this intriguing V-8-powered coupe. "^^<http://www.w3.org/2001/XMLSchema#string>
