Today, Hyundai Motors introduced their first direct-injection gasoline powered engine. According to Hyundai, the 2.4-liter engine, dubbed the Theta II, delivers more power while improving fuel-efficiency by 10%, reports Automotive News.

The new engine, set to debut in the redesigned Hyndai Sonata early next year, took four years and $147.4 million to develop. The Korean automaker plans to eventually introduce direct-injection technology across its entire line gas powered engines.

Hyundai reports that when compared to conventional engines of equal size, the Theta II delivers 7% more torque at low revolutions and 12% more at higher revolutions. Gas mileage is also increased by about 10% over conventional engines.

The engine will debut in the redesigned 2010 Hyundai Sonata sedan, due in U.S. dealerships early next year.
