A study was conducted to see if relative fuel economy advantages exist for a ceramic turbine engine when it is downsized for a small car. A 75-kW (100-hp) single-shaft engine currently under development was analytically downsized to 37 kW (50 hp) and analyzed with a metal-belt continuously variable transmission in a synthesized car. With gasoline, a 25-percent advantage was calculated over that of a current spark-ignition engine, scaled to the same power, using the same transmission and car. With diesel fuel, a 21-percent advantage was calculated over that of a similar diesel-engine vehicle.
