Shah Alam, 1 April 2010 - Hyundai Motor America debuted its 2.0-liter Theta II turbocharged gasoline direct-injection (GDI) engine in the 2011 Sonata at the New York Auto Show today. With the addition of the all-new 2.0-liter Theta II turbocharged GDI engine, the new 2011 Sonata offers an unprecedented combination of segment-leading fuel efficiency and power – with an estimated 34 mpg highway rating, and 274 horsepower.  Remarkably, the Sonata 2.0T produces these industry-leading metrics on regular fuel…premium fuel is not required

The new Sonata is the first Hyundai vehicle to have both GDI technology and a turbocharger. By the end of Hyundai’s 24/7 version 2.0 product initiative (seven new models in the next 24 months), four nameplates will be available with GDI or the combination of GDI and a turbocharger. Turbocharging and GDI are part of “Hyundai Blue Drive,” the company’s environmental initiative to continue industry leadership in fuel efficiency and sustainability.

“The Sonata 2.0T is a great example of what our Blue Drive product strategy is doing for consumers,” said John Krafcik, Hyundai Motor America president and CEO. “Think about it – more horsepower than any of our V6 competitors, with better gas mileage than any competitive 4-cylinder model. We’re not fans of compromising at Hyundai, and the Sonata really demonstrates this aspect of our business approach.”

The 2.0-liter turbocharged GDI four-cylinder engine in the 2011 Sonata produces 274 horsepower at 6,000 rpm and 269 lb-ft of torque from 1800-4500 rpm with regular fuel. The Sonata 2.0T will deliver 22 mpg city and 34 mpg highway (preliminary estimates). Hyundai’s turbocharged engine features a twin-scroll turbocharger that when combined with the GDI system results in instantaneous power delivery. Twin-scroll turbochargers have traditionally been used on more expensive high performance engines, but as with GDI, Hyundai has chosen once again to apply this efficient technology in high volume to its most popular model.

Hyundai also unveiled its 2011 Sonata Hybrid, changing the game in hybrids with unique approaches in hybrid powertrain design, battery technology and vehicle appearance. The Sonata Hybrid is Hyundai’s first hybrid in the U.S. market.

“The Hyundai Sonata Hybrid is the new kid on the block, but it’s not a follower,” says John Krafcik, president and CEO, Hyundai Motor America. “Its full parallel hybrid configuration and breakthough lithium polymer batteries offer a new take on traditional hybrid design, while its unique design sets it apart from the mid-size hybrid pack.”

The Hyundai-developed Hybrid Blue Drive architecture is a full parallel hybrid drive system, which can operate on an electric motor, gasoline internal combustion engine, and a combination of the two depending on driving conditions and driver demands. Hyundai’s proprietary full parallel architecture differs from the power split technology used by most competitors, allowing significant efficiency advantages at higher speeds. Hyundai Hybrid Blue Drive is the first and only system using lithium polymer battery technology – leapfrogging competitive in-market nickel-metal hydride and lithium-ion applications. Lithium polymer offers the benefits of lithium-ion, a technology used in laptops and cell phones, but adds robustness, power-density and package flexibility, making it ideal for automotive applications. Hyundai Hybrid Blue Drive also is unique in its use of the company’s own highly efficient, compact new 6-speed transmission, modified with hybrid starter-generator, electric motor, and low-friction oil pump, which together allow the elimination of the traditional torque converter.  

Hyundai Hybrid Blue Drive is a new addition to a full suite of eco-focused products and technologies that Hyundai offers in its goal to be the auto industry’s global eco-leader. According to the EPA, Hyundai has led the U.S. industry in fuel economy for 2008 and 2009, and is currently the only automaker with average fleet fuel economy of more than 30 miles per gallon.

“Hyundai applies advanced technologies to vehicles to provide the best solutions for the everyday driver,” said Krafcik. “Unlike traditional hybrids that trade off highway fuel economy for higher city ratings, the Sonata Hybrid delivers best-in-class highway fuel economy, while still delivering about a 40 percent improvement in city fuel economy compared to a Sonata equipped with the Theta II GDI engine. We think this is a better balanced approach for the majority of car buyers.”
