Would ozone be more efficient in a car engine than oxygen gas?

Yes from simply a thermochemical point of view, but practically it is not. It takes energy to form ozone. Ozone is very corrosive to metals ( steel wool detonates if you throw it into liquid ozone; if you spilled ozone on a tar covered road, the road would catch fire, ozone is extremely toxic, ozone is an air pollutant ) so it has a lot of things going against it from a practicality point of view. N2O would also be a good oxidant, but it too has practical problems. For example:

CH4 + 4N2O = CO2 + 4 N2 + 2 H2O

still makes CO2, and the high flame temperature would probably cause the formation of other noxious nitrogen oxides.
