Why gas consumption differs from highway to city
In: Engineering
City traffic is, as a rule, less efficient than highway traffic because you’re constantly speeding up and slowing down in the city. Slowing down functionally wastes the kinetic energy of the vehicle, and requires you to burn extra fuel in order to accelerate again. Further, you end up burning fuel needlessly while waiting at the lights. All of that extraneous combustion adds up, and kills your fuel mileage.
On the highway; there’s no starting or stopping, so your car can just sit at it’s optimal speed/load and produce power.
