The cat has been out of the proverbial bag on the Genesis coupe for quite some time now, complete with full high-res photographic evidence. However, despite the massive holes in the photo embargo, factual details of Hyundai's new front-engine rear-drive coupe have been scarce. That has been remedied by the official reveal in New York this afternoon, and we have the full story.

Rumors of a V8-engined model have proven false. Instead, the expected 3.8L V6 and turbocharged 2.0L four-cylinder are the sole offerings. Producing a Camaro-beating 310hp (on premium fuel) in V6 form, the Genesis coupe will be a serious contender in the performance coupe class. In four-pot form, however, the speculated turbo-four Camaro can breathe easier as the Hyundai only puts out 223hp (again on premium fuel). With a curb weight of just over 3,500lb (1590kg) the V6 coupe will have a power-to-weight ratio in a league with the Mustang GT and Nissan 350Z, although Hyundai likens the coupe to Infiniti's considerably more luxurious G37. The turbocharged four weighs in about 100lbs less.

Transmission options include a six-speed manual or five-speed auto for the four-cylinder car, or a six-speed manual or six-speed auto for the V6 variant. Both cars get four-wheel disc brakes, and both have an optional four-piston Brembo package available, which ups the diameter from the standard 12.4-inch rear and 12.6-inch front to 13.0 and 13.6, respectively. Claimed top speed is 149mph for the V6 and 137mph for the four-cylinder.

Standard safety equipment includes anti-lock brakes, electronic brake distribution stability control and a full complement of front, side and curtain airbags.

The Genesis coupe is due to hit showroom floors in Q1 2009 as a 2010 model.
