Why gas consumption differs from highway to city
In: Engineering
Accelerating from a stop requires more gas for a variety of reasons having to do with gears and the efficiency of the engine at various rpms.
Highway driving benefits from momentum. When you let go of the gas the car still continues to roll for a while. So it doesn’t take a lot of energy to maintain a fast speed. But in the city you are constantly stopping at lights and stop signs, wasting that momentum.
