What happens to your fuel efficiency when you drive with constant braking and acceleration?
Gentle braking saves on the forward momentum of the car when immediately required to accelerate back again to normal speed. This bad driving technique can reduce fuel efficiency by 10 – 40 %.
How does braking affect fuel economy?
Heavy Braking or Acceleration Aggressive driving forces your car to switch gears at a faster rate than is optimal for fuel efficiency. EPA testing indicates that frequent, heavy braking and quick acceleration could reduce your fuel economy by as much as 33% during highway driving.
What can you do to increase fuel efficiency while driving?
Check out our tips for fuel-efficient driving and learn how to save gas while you watch the savings add up.
- Don’t Be a Lead Foot.
- Keep it Steady for Fuel-Efficient Driving.
- Stay Alert and Keep Proper Distance.
- Don’t Slam on the Brakes.
- Check Your Tire Pressure.
- Be More Fuel Efficient with Less Cargo.
- Combine Trips.
How does driving habits affect fuel efficiency?
Aggressive driving (speeding, rapid acceleration and braking) can lower your gas mileage by roughly 15% to 30% at highway speeds and 10% to 40% in stop-and-go traffic. Excessive idling decreases MPG. Driving at higher speeds increases aerodynamic drag (wind resistance), reducing fuel economy.
Does using your brakes waste gas?
So why does braking use fuel? It’s the way you brake, rather than braking itself. Continuously slamming the brakes causes less fuel efficiency as the car works harder to accelerate, so taking it slow and easing to a stop or using engine braking is a better solution to saving fuel.

It can lower your gas mileage by roughly 15% to 30% at highway speeds and 10% to 40% in stop-and-go traffic. 1,2
Why does the price of gas go up when you drive faster?
At higher speeds, the estimated price per gallon is increased based on the additional fuel you use by driving faster. The price of fuel doesn’t actually go up, but this is a useful way to put the cost of driving faster in context. Cost/100 Miles: This is useful for estimating fuel costs for long trips.
When does gas mileage decrease the most?
While each vehicle reaches its optimal fuel economy at a different speed (or range of speeds), gas mileage usually decreases rapidly at speeds above 50 mph. You can assume that each 5 mph you drive over 50 mph is like paying an additional $0.21 per gallon for gas. 4
How does idling affect your gas mileage?
An extra 100 pounds in your vehicle could reduce your MPG by about 1%. 6 The reduction is based on the percentage of extra weight relative to the vehicle’s weight and affects smaller vehicles more than larger ones. Idling can use a quarter to a half gallon of fuel per hour, depending on engine size and air conditioner (AC) use.
