Hyundai Motor today unveiled the 2.4 Theta II GDI, its first Gasoline Direct Injection engine before an audience of engineers attending the Ninth Annual Hyundai-Kia International Powertrain Conference. Representing the biggest advancement 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 ratio of 11.3:1, the 2.4 Theta II GDI delivers 201ps@6300rpm and 25.5kg.m@4250rpm in its Korean domestic market specification.
Developed with a budget of 170 billion won over a 46 month-long research period, the new 2.4 Theta II GDI engine will make its debut in the first half of 2010 starting with the recently launched Sonata, beating the mid-size sedan competition to market with this exciting new technology. GDI application will subsequently be expanded across the gasoline engine family and applied to other Hyundai models.
