For 2012, Hyundai Genesis' award-winning Tau 4.6-liter V8 powerplant will now be coupled exclusively with an in-house-developed eight-speed automatic transmission with SHIFTRONIC, adding benefits in acceleration and efficiency. Internal engineering tests estimate this new eight-speed transmission to be six percent more efficient at transferring power than the former 6-speed automatic, increasing highway fuel economy from 25 mpg to 26 mpg.

This same 4.6-liter Tau V8 engine was already significantly improved for 2010 with induction and tuning enhancements increasing peak output from 375 to 385 horsepower. A variable intake system, iridium-tipped spark plugs, anti-knock control, and multi-port injection further add to the sophistication of this engine.
