Slated for use in the Genesis sedan as well as the larger Equus, Hyundai's new V8 will use direct injection to produce 429 horsepower and 376 pound-feet of torque. That's a healthy increase of 59 horsepower and 8 ft-lbs of torque over the 4.6-liter V8 it's replacing

Since the Genesis Coupe debuted back in 2008, the horsepower wars have raged on with cars like the Ford Mustang going from 210-hp to 305-hp. Once seen as a bargain, the G Coupe is a slightly less enticing package than it once was. To combat this, Hyundai will look to add more power to the Genesis two-door in 2012, along with a slight facelift, AutoGuide has been told.

Both the 4-cylinder and V6 engines are slated to get upgrades, although exactly how extensive they will be is not yet clear. It’s not hard to speculate that the 2.0T model could gain the Sonata Turbo’s new engine, prompting a significant increase in power from 210-hp to 274-hp. That would come very close to the 3.8-liter V6′s 306-hp number, suggesting it would also have to receive a major update, be it through naturally aspirated means, forced induction, or a switch to a V8. Past reports have already indicated the company’s new 5.0-liter V8 will replace the current 3.8L V6, producing a rather significant 429-hp.
