Hyundai Motor America has confirmed the introduction of the company’s first direct-injection gasoline engine will debut in the 2011 Sonata.

Called the 2.4 GDI Theta II, the engine will make 200-hp at 6300 rpm and 186 ft-lbs of torque at 4250 rpm in the SE model. Hyundai has also confirmed that despite the engine’s 11.3 compression ratio it will get full power on regular 87 octane gas. A GLS model will make slightly less power, with 198-hp on call.

In total, this is an increase of 25-hp and 18 ft-lbs of torque over the old 2.4-liter motor.

Along with DI technology, the GDI Theta II will also get a six-speed automatic transmission that is more compact, has 62 fewer moving parts and weighs about 20 lbs less.

The result is what Hyundai believes will be best-in-class fuel economy of 23 and 35 mpg.

    I have no doubt about the claims and aspirations stated for the most recent iteration of Hyundai vehicles. I have driven a 2009 Genesis 30K+ miles since 07/05/08, and it's almost unbelievable claims have been more than equalled.......with NO disappointments or needed repairs, failures or even adjustments. It is unqualifiably the best of the 46 cars of any (of any type,size, brand or country of origin) that I have owned. It is the best dollar value and quality, and is the safest automobile I've owned. I enjoy driving it almost as much as my 1958 356B normal Porsche(the all time favorite} as a fun ride. I'd bet on anything that Hyundai currently builds, based upon the quality of their efforts of and the integrity of design and execution of construction. I'm sure U.S. cars will follow suit. I'd must bet on that too.
