Karma Automotive--the carmaker formerly known as Fisker Automotive--says it will use BMW powertrain components in upcoming production models.
BMW will supply high-voltage battery charging systems and "a wide range of hybrid and EV systems" for the Karma luxury sedan, which the company expects to relaunch in 2016.
Karma did not say whether BMW would also supply the car's range-extending gasoline engine, which was previously provided by General Motors.
All Karmas that were part of the original 2012 production run used a 260-horsepower 2.0-liter turbocharged and direct-injected four-cylinder, which turned a generator to provide electric power.
Actual propulsion came from two 150-kilowatt (200-hp) electric motors--one per axle--and a 20-kilowatt-hour lithium-ion battery pack.
The components supplied by BMW could come from a few potential sources.

At its Innovation Days event in 2014, BMW also unveiled a plug-in hybrid test mule--based on the 5 Series Gran Turismo--designed to maximize electric running.
It used a 200-kW (268-hp) electric motor to drive the rear wheels, with a 150-kW (201-hp) driving the front wheels with some assistance from a turbocharged four-cylinder engine.
Both of these vehicles have somewhat different powertrain configurations to the Karma, but some of their components could find their way into the sedan.
Before Fisker's 2012 bankruptcy, there were rumors that BMW would supply engines for a second Fisker model, called the Atlantic.
The Atlantic was a sedan smaller than the Karma, but had similar styling and also used an extended-range electric powertrain.

While all previous Karmas were built under contract by Valmet Automotive in Finland, Karma Automotive plans to move production to the U.S.
It is building a factory in Moreno Valley, California--not far from its headquarters in Costa Mesa.
Previous plans to use a former General Motors factory in Delaware have been put on hold.
