The Hyundai Genesis sedan has only been on sale for a month, but the automaker is already considering upgrading the current 4.6-liter V8 with a 5.0-liter version. Hyundai's North American product chief, John Krafcik, told MotorTrend that the Tau V8 could be stroked up to 5.5-liters, but the ideal displacement to keep fuel economy on par with power is an even five liters.

The plan is to increase the displacement of the V8, as well as adding direct-injection to Hyundai and Kia's range of fours, sixes and eights over the next few years. It's a move that several automakers have already adopted and Hyundai's decision to increase its V8's displacement will only happen if it can keep output the same or better while retaining the 4.6-liter's fuel economy.
