Hyundai has released a teaser shot of the hybrid Sonata, and it appears to differ a bit from the gasoline-powered version with a different grille and reconfigured fascia.

The car expected to use a lithium-ion battery, John Krafcik, Hyundai's top U.S. exec, has said. Hyundai calls its eco-technology "Blue Drive." News of the Hyundai hybrid arose in August 2008, when Krafcik told reporters at a test-drive about the company's plans. The company showed a prototype at the Los Angeles auto show last year.

A turbo Sonata also will be revealed in New York.

Hyundai is using the Sonata to push ahead its design language and increase its penetration in the midsize segment.
