Maybe 75% for the ideal cycle, but I don't believe they can get anywhere near that in actual practice. Still, based on the approach they are using, I wouldn't be surprised to see north of 50%. Extremely high compression with constant volume combustion does seem the best way to optimize efficiency in an internal combustion engine. If they can protect from the high temperatures, solve the problems with sealing rotary engines, and minimize friction, then it's seems it'll be a winner. Those high peak pressures and temperatures are gonna be tough to deal with for longevity.

Hypothetically possible. If they are injecting water inside the combustion chamber, I can certainly see efficiencies of better than 50% being possible. Keeping that water from freezing in a car in the winter could be a problem though.
 
Doody calls. I would really rather that it didn't. Comfort me wise and sterile tiny ad:
