ICE engines convert less than 40% of gasoline's energy into movement, and the rest is lost as heat. This inefficiency is unfixable: the waste heat can't be avoided in a combustion engine. In cars there isn't enough space and carrying capacity for a steam turbine that could make a good use of the heat. In a stationary power plant, there is. Stationary power plants are incredibly efficient, to the point that burning gasoline and transmitting electricity to an EV is still way more efficient than burning gasoline in a car. You may be mixing up things with natural gas used for heating. Fuel -> heat is most efficient at the destination. But ICE cars don't run on heat, they radiate it away as waste.
