I'm aware of turbine engine inefficiencies under low load, but I understood them to be very efficient under high load.
The Chrysler cars, after a couple years of tinkering, went from 13 or 14 mpg up to 18 and 20 mpg. Figure the cars weighed 3600-3800 lbs, since they were big sedans. No CVTs...
First post for me here (but have read hundreds) :-)
This idea has been rolling around in my head for several years now. I know that about 30-40 years ago, Chrysler (and perhaps others?) was experimenting with turbine engines in cars. I remember a Speed Channel (when it was Speedvision)...
