When a car's engine burns fuel the energy/heat produced goes mainly three ways ~ (a) producing power to move the car, (b) out of the exhaust pipe, and (c) into the coolant. If you want the car to consume a small amount of fuel for the same performance (as in a diesel) then you can expect (b) and (c) to receive only a small amount of energy/heat.
