The 2013 Hyundai Genesis Coupe has been one of the most leaked cars of the new auto show season. Just yesterday we learned about its new powertrain specs, including news of an eight-speed transmission option, and now we have a boatload of new images including some shots of the updated interior.

The images show some of what was previously leaked (though in higher resolution). While we're not 100 percent sold on the very busy front end, the overall effect, including the ducted hood, is positive.

The Genesis Coupe was already a smart-looking two-door; now it looks a bit meaner, and certainly more high-tech.

High-quality materials and metal accents add a sporty and modern touch to the  interior, while the standard multi-gauge located on the center fascia is certainly a welcome addition to the performance driver.

As for what we expect to find under the hood? Starting with the base 2.0-liter four-cylinder engine, peak output has been lifted to 271 horsepower and 275 pound-feet of torque. This represents a jump of 61 horsepower and 52 pound-feet of torque over the outgoing model, courtesy of a new twin-scroll turbocharger and larger intercooler.

The 3.8-liter V-6 meanwhile gains 39 horsepower and 29 pound-feet of torque over the pre-facelifted Genesis Coupe, with its final figures pegged at 345 horsepower and 295 pound-feet of torque. Hyundai says most of the gains can be attributed to the addition of direct injection technology.

Hyundai is also quick to point out that a new “sound generator” has been installed, possibly a special exhaust modification, to help add a more emotional note to the engine.

Stay tuned for even more details as we approach the 2013 Hyundai Genesis Coupe’s world debut at the 2012 Detroit Auto Show this coming January.
