Renault and Geely’s Horse Powertrain has unveiled a new type of range extender for electric vehicles.

The D20 combines a 2.0-liter turbocharged four-cylinder engine with a new kind of electric motor.

The combustion engine runs off 100% methanol fuel blends, while the generator is smaller and more powerful than conventional electric motors.

Extended-range EVs, or EREVs, promise to eliminate two of the biggest issues associated with conventional electric cars: range anxiety and charging anxiety. That’s great on paper, but they still burn gasoline to create energy.

Now, though, there’s a new type of range extender that claims to be more efficient and environmentally friendly than its predecessors.
