The problem that Chrysler and Jay Leno found is that jet engines work best at full RPM with no changes. Jay found that his Eco-Jet idled at 200HP and he had to be on the brakes all the time in normal driving, then he had nothing left in reserve to stop at speed. He got custom Brembo brakes in order to keep the Corvette brakes he tried at first from burning up. Not really good for a road car.
But a turbine is perfect for twisting a generator at a constant speed.
