it is strange though that turbine based hybrid cars (in series or range extender configuration) haven't emerged in the recent years. It would be best of the 2 worlds - a small lightweight turbine as a generator would work in the most optimal mode, and the torgue/etc. characteristics of the car would be that of the electric motor.
Wrt. nuclear - while nuclear on Earth is pretty much done away (at least for fission, for fusion - well, once somebody develops a laser pulse efficiently fusing proton+boron it probably can have a chance), the space is the true nuclear ___domain. In particular i think that launch window and flight time limits of flying to Mars would naturally lead to nuclear powered LEO-to-Mars Starships.
None of the car manufacturers have experience with turbine manufacture (except I guess Rolls Royce, and they don't build Hybrids).
The Hybrid system was already a pretty big ask for the car companies and developing a novel compact hardy turbine at the same time was just too much. Plus hybrids are seen as more of a stepping stone to pure electric vehicles so you might put a ton of time and energy into developing it only to have the entire concept become obsolete in only a few years.
Don't be too sad though, turbine technology does live on, the M1A1 and M1A2 Abrams main battle tank. It's the reason for the incredible land speed but also ridiculous fuel consumption and enormous IR signature.
There are gas turbine based buses and trucks used in eastern Europe where LNG imported from Siberia is plentiful.
They're not common in my city, but there's (only) one on the bus line that drives by my house. It's only a bit louder than piston engines buses, but the sound is very distinctive so you can hear it from a mile away.
