New York, New York – Hyundai has unveiled two new powertrains for the 2011 Sonata at the New York Auto Show, including a turbocharged engine and a hybrid version that uses breakthrough lithium polymer batteries that “leapfrog” existing nickel-metal hydride and lithium-ion technology, the company said.

The 2011 Sonata will be the first vehicle in the industry to offer three technologies: gasoline direct-injection (GDI), twin-scroll turbochargers, and full hybrid powertrain. The Sonata Hybrid is the company’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,” said John Krafcik, president and CEO of Hyundai Motor America. “Its full parallel hybrid configuration and breakthrough lithium polymer batteries offer a new take on traditional hybrid design, while its unique design sets it apart from the midsize hybrid pack.”

The Hyundai-developed Hybrid Blue Drive architecture can operate on electricity, gasoline or a combination of the two, and allows significant efficiency advantages at higher speeds. Its lithium polymer battery offers the benefits of lithium-ion, but adds robustness, power density and package flexibility. Hybrid Blue Drive is also unique in its use of the company’s compact new six-speed transmission, modified with hybrid starter-generator, electric motor and low-friction oil pump, which together allow the elimination of the traditional torque converter.

The company also unveiled its Sonata 2.0T, using Hyundai’s first four-cylinder turbocharged gasoline direct-injection engine. The new powertrain produces 274 horsepower and 269 lb-ft of torque, available from 1,800 to 4,500 rpm, giving it more power than many V6 engines while running on regular fuel.

The new Sonata is the first Hyundai vehicle to have both GDI technology and a turbocharger. By the end of the company’s initiative to produce seven new models in the next 24 months, four nameplates will be available with GDI, or with the combination of GDI and a turbocharger.
