content: The main advantage of turbine engines is power to weight ratio, which is why they're used in planes. Fuel economy is horrible.

content: In modern turbines fuel economy is not that bad - it can be actually pretty good, but those are large ones for small fast starting power plants. I don't know about the small ones. Still they use turbines in turbo prop planes, so efficiency should not be that bad.Another problem with turbine engines is that they are relatively slow in reacting to power changes. So likely less responsive than an old diesel engine, though better than steam power.An advantage of a turbine is that if well made there are little vibrations and a long service life is possible.There is a small chance we might see the idea of a turbine engine in a car again, as a range extender / generator in a hybrid. This would also save the gears to bring down the high RPM down to a street level.

content: The problem with turbines in car applications is that they are quite efficient at rated power，but when throttled back the efficiency figure take a nose dive off a cliff, now for aircraft use where most of the cruise is at a fixed speed that is fine, for a car it’s not the case

content: Quote from: CJay on August 28, 2018, 09:40:03 amIn March 1950, Rover showed the JET1 prototype, the first car powered with a gas turbine engine, to the public.JET1, an open two-seat tourer, had the engine positioned behind the seats, air intake grilles on either side of the car,and exhaust outlets on the top of the tail.During tests, the car reached a top speed of88 mph(142 km/h).[citation needed] After being shown in the United Kingdom and the United States in 1950,JET1 was further developed,and was subjected to speed trials on the Jabbeke highway in Belgium in June 1952,where it exceeded 150 miles per hour (240 km/h).JET1 is currently on display at the London Science Museum.Hmmm.... Seems a bit suspicious...!
