Automotive News reports that Hyundai's American product chief John Krafcik confirms the Korean automaker is working on a hybrid powertrain for its mid-size sedan. He tells the News that the hybrid will feature a lithium-ion battery--the advanced kind being developed by Toyota, GM, and others--and that a prototype will be shown this fall.
The hybrid Sonata likely will be modeled after the next-generation Sonata; the current sedan bowed in 2006. The new hybrid is expected as a 2011 model. And while it will offer battery-augmented power, it won't be a plug-in, Hyundai's Krafcik adds.
