If a car is going to use a series hybrid or extended range EV powertrain a a conventional piston engine is hardly the optimal package for a range extender. Something smaller and more power dense would be preferred. A small turbine engine is one possibility and that's exactly the approach taken by Langford Performance engineering. They've used a micro-turbine from California-based Capstone Turbine. A turbine works well in this type of application because it can run at constant speed.

There seems to be tons of innovative technologies being proposed, tried and tested these days. Some of the wilder ideas disappear quickly while others, which were thought to have gone extinct, make a dramatic comeback. One such cool tech is the automotive turbine.
