2010 Hyundai Sonata

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.

    Hyundai is Korean, it was a mistake.

    Anyway, The 2011 Hyundai Buick Regal Killer's 2.4L (this is just the base engine) will also have 210 HP with 35 MPG. That's about a 10% increase from the current Model. Not to mention that it will get a Hybrid capable of 43 MPG, and a Turbo that gets 275 HP.
