Yes. A gas turbine provides it's drive from the spinning shaft of the turbine as opposed to a jet engine which uses the velocity of the exhaust gasses as thrust.
A turboprop aircraft uses a gas turbine. It sounds like a jet but it has a propeller driven via a gearbox off the turbine shaft.
The engine in that 928 would be driving through a reduction gearbox then most likely on to the automatic transmission.
What I don't knowis how you would control speed of the car. I wouldn't have thought that you throttle back the engine so I imagine that the gas turbine runs at a constant speed and there is some way to control how much 'drive' you put out into the transmission?
