Along with the public unveiling of the production Karma plug-in hybrid sports sedan, Fisker will also takes the wraps off a new concept car at next month's Detroit Auto Show. The concept is called Karma S, where S stands for Sunset - something that could point towards a convertible version of the Karma saloon. The California based company said that the Karma S will be powered by the Karma's Q-DRIVE powertrain, developed in cooperation with Quantum Technologies exclusively for Fisker. The system offers a 50 mile range on a single charge to its Lithium-Ion battery pack, and an output of up to 408HP from the two electric motors. Fisker will announce more details about the Karma S at the company's press conference on January 12, 2009.Source: Fisker , Via: Autobloggreen
