The Otto cycle has been around for almost 150 years and many things have been done to it since the invention. It will never be 100% efficient because the piston stops twice every time the heat is turned into energy.
Gasoline engines will never be 100% efficient but that 60% efficiency number of the dual fuel engine is pretty close to that of electric cars.
