How Much More Fuel Will You Use By Driving At 70 Mph, Compared With Driving At 50 Mph?
Your vehicle consumes less fuel when you avoid hard acceleration. Higher engine revs lead to more fuel consumption. For example, driving at 70 mph uses around 15% more fuel than at 50 mph over the same distance in the same gear. However, ensure you're not driving so slowly that it disrupts or endangers other road users.
It’s not just the extra miles that make your gas tank empty more quickly when you travel. Speed plays a significant role in fuel efficiency.
So, how much more fuel will you use by driving at 70 mph, compared with driving at 50 mph? The answer is: that compared to 50 mph, driving at 70 mph can consume up to 15% more fuel.
Why? It’s All About Engine Performance
The engine in your car works very hard to keep you moving. The harder it has to work the faster you go. To keep up, more fuel must be burned.
Another factor is aerodynamics.
Wind resistance rises with speed. Your engine must work even harder to maintain speed because of this unseen force which acts like a pushing wall. To overcome this wind resistance at higher speeds more fuel is required.
Fuel Efficiency: A Modest Operation.
Speed is one of many important factors that affect fuel efficiency. Your gas mileage can be greatly increased by controlling your speed.
Reduce Speed, Increase Savings
Now that you know how much more fuel will you use at 70 than 50. Keep this in mind the next time you’re traveling: a little slower speed can add up at the gas pump.
Bonus Tip: You may further reduce fuel consumption by braking gently and accelerating gradually. Drive sensibly and sparingly!
