California based electric-car startup Fisker Automotive is all set to convert an old, non-functional General Motors unit in Wilmington, Delaware, into a plug-in hybrid electric-car manufacturing plant. The exciting new development, which has managed to interest analysts and investors all around, is scheduled to be formally announced tomorrow.

GM's Wilmington unit is nearly 52 years old and has been non functional for some time. Fisker has every plan to use this unit to build its much speculated and touted $48,000 Project NINA hybrid cars, production of which, if things go as planned, will start in 2012.

The plant is expected to employ around 1,500 workers and manufacture up to 100,000 cars annually. The family hybrid by Fisker, which is yet to be formally christened, but is currently known by the code name NINA, will be the company's second hybrid to hit the American market, the first being Karma, a luxury sports car priced at $89,000. Fisker plans to start delivering Karma to US customers next summer.
