During a recent powertrain briefing, Hyundai revealed some more details about its new 5.0-liter Tau V8 and 1.0-liter Kappa three-cylinder engines that will be used in a variety of global markets in the near future.

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, while also increasing fuel economy by one mile per gallon to 18/26 thanks to an all-new eight-speed automatic transmission. Hyundai has not mentioned any plans to offer the new Tau 5.0 in any other products, though we'd love to see it shoehorned under the hood of a Genesis Coupe. (Full disclosure: We really want to see a 5.0 battle between the Genesis Coupe and Mustang GT.)

On a much smaller level of displacement, Hyundai also detailed a new 1.0-liter Kappa inline three-cylinder engine that will be offered in other markets in the new i10 subcompact. Currently, this engine produces 69 horsepower and returns around 55 miles per gallon on the United States testing cycle. And while this 1.0-liter engine currently isn't slated for consumption here in the States, future versions of the Kappa engine could come to our shores. Hyundai says that we'll see a turbocharged, 110-hp version of the 1.0-liter three in 2012, and that a turbocharged 1.2-liter Kappa will be released shortly thereafter. The 1.2T is estimated to produce around 130 to 140 hp, making it more suitable for American-sized vehicles.
