Hyundai bumps the output of Genesis V8 by 10hp for 2010
Filed under: Hyundai
Even with two completely redesigned models debuting in the coming weeks, Hyundai won't leave its carryover models alone for the 2010 model year. Engineers have tweaked the 4.6-liter V8 in the Genesis sedan and extracted an extra ten horsepower from the Tau to bring peak output up to 385 hp at 6,500 rpm.
Hyundai Technical Center powertrain director John Juriga acknowledged that the performance stats will remain the same, but drivers will be able to feel the increased grunt. The revisions not only increase output, but also improve the refinement and driveability of the V8 to feel more responsive at the low end of the tach.
To achieve its goals, Hyundai added a two-step variable induction system that varies the flow through the intake manifold at low and high rpm, along with continuously variable valve timing on both intake and exhaust, larger valves, and a chromium nitride coating on the pistons to reduce friction. The updated Genesis sedans will be arriving in dealerships later this year.

That's cool but I would like to see them concentrate more on the V6 engine as that will have more sales both in the coupe and sedan Genesis. Plus with a few extra HP in the coupe it Would better keep up with the G37 and such.

With the changes they made, I think you'll be able to feel it. Most of them won't help much at max power output but should help it have more torque pretty much everywhere. I'll bet that there was a good bump in torque at the low end.
