Hyundai Sonata Gets A New GDI Heart
Taking one step closer to its goals of leading the industry in fuel economy, Hyundai Motor Company today launched its new Sonata 2.4 GDI in the Korean market, its first Gasoline Direct Injection engine whose superior performance puts Hyundai at the top of the mid-size segment.

Equipped with the new 2.4 Theta II GDI, the new Sonata generates 201ps@6300rpm of horsepower and 25.5kg.m@4250rpm of peak torque while delivering fuel economy rating of 13km/l. The 13km/l figure is 0.2km/l better than the smaller displacement 2.0-liter Theta II which serves as the base engine for the Sonata. (See attached file for direct comparisons with Camry and Accord)
Hyundai is the first non-luxury automaker to bring GDI to the mid-size segment. Representing the biggest advance in fuel injection, an ‘80s technology that replaced the carburetor, GDI puts Hyundai at the cutting edge of engine design and management by achieving three seemly incompatible goals: GDI lowers emissions while raising power output and improving fuel economy. Prior to GDI, a gain in one area came at the expense of the other two.
With a compression ration of 11.3:1, the 2.4 Theta II GDI delivers 201ps@6300rpm and 25.5kg.m@4250rpm in its Korean domestic market specification.
“The Theta II GDI convincingly demonstrates Hyundai’s advanced powertrain engineering capabilities,” said Dr. Lee Hyun-Soon, vice chairman and Chief Technology Officer.
