the car. Where does the other 80% go and is this a violation of the law of conservation of energy?

The rest 80% goes to the air as heat. So there is no violation of the law of conservation of energy (1st law of thermodynamics). If 100% of the energy was converted to work (mechanical energy) THAT would be a violation of the SECOND law of thermodynamics.

Internal engine friction, friction with the road, aerodynamic friction, and waste heat.
Most of the energy from burning gasoline goes out the radiator into the air in the form of wasted heat. Why then have a radiator? To stop the engine from melting or cracking under high heat, of course. Steel can only take so much heat.

No it would be a violation if it made over 100%
You have heat coming out. If it was a perfect engine 100% conversion it would all go to making the car go and there would be not heat.
