A steep downhill grade can cause your vehicle to speed up faster than the cruise control setting and safe road speeds.

Does driving slower 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.

Does your AC use more gas?

Yes — like many of your car’s features, the air conditioning system uses gas. The air conditioner draws energy from the alternator, which is powered by the engine. Fuel is needed to power your Toyota car’s engine. However, in some situations, using the AC can be more efficient than not using it.

What is most fuel efficient speed?

7. 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. Any faster, though, and the fuel efficiency decreases rapidly. For example, driving at 85mph uses 40% more fuel than at 70mph (oh, and it’s illegal too).

Can cruise control mess up your transmission?

Does cruise control save gas on hills?
