General Motors, Chevrolet’s parent company, is thinking about recovering some of its investment in the Voltec drivetrain, which was employed by the 2016 Chevrolet Volt.

Since recovering the development costs through sales will take several years and the company will then have to reinvest the money in a new generation of the system, GM wants to license it to other carmakers. The American company has not specified any potential customers or whether it has been approached by a potential buyer, but the idea is in the air.

The Chevrolet Volt features an 18.4 kWh lithium-ion battery that powers an electric motor. The two are supplied with electrical energy from a 1.5-liter four-cylinder internal combustion engine that works as a range extender. The term is a fancy definition of a generator, as the internal combustion unit does not directly drive the wheels. With a full charge, the Volt can travel up to 53 miles (85 km) on electric power alone. The range extender then kicks in to allow a maximum range of 420 miles.
