Does driving slow save gas?

Going slower technically saves fuel because at high speed your engine needs to work harder to overcome drag from wind resistance, your tyres and transmission, and that drag increases exponentially the faster you go. Reduce your speed, then less power (and thus fuel) needs to be expended to overcome that drag.

What burns gas faster?

At speeds over 60mph, gas mileage drops off a lot more than most drivers probably realize. “The aerodynamic drag created by a vehicle moving through the air increases exponentially,” says Pokrzywa. It takes more power to overcome the added resistance, which forces the engine to work harder, burning more fuel.

65mph7. The Energy Saving Trust says that the most efficient speed you can travel in a car in terms of achieving the best fuel economy is 55-65mph.
