The problem with crawling up a hill slowly is only a matter of engine efficiency.
Your basic physics are incorrect. Without a force counteracting gravity, a vehicle will roll downhill. That force is provided by the engine and can be tested by stopping on a steep hill in an automatic transmission car. It takes some amount of energy to prevent the car from rolling downhill when the brakes are released. It takes yet more energy to produce forward movement.
