What is the most fuel efficient speed to drive?
You can improve your gas mileage 10 – 15% by driving at 55mph rather than 65mph (104km/h). Natural Resources Canada puts the “sweet spot” for most cars, trucks, and SUVs even lower, between 30 mph (50 km/h) and 50 mph (80 km/h). Note how quickly efficiency drops after 60 mph.
Does speed affect fuel consumption?
Speeding increases fuel consumption and decreases fuel economy as a result of tire rolling resistance and air resistance. Reducing your speed by 5 to 10 mph can improve fuel economy by 7%–14%. Using cruise control on the highway can help drivers maintain a constant speed; vehicles use the most energy when accelerating.
Do you use more fuel going faster or slower?
The common understanding is that going faster burns more fuel and therefore, the slower you drive, the less fuel your car will use, but this actually isn’t true. Most cars’ peak fuel efficiency occurs somewhere between 50-60 miles per hour.
Do you save fuel by driving slower?
There’s a very simple way to save money on petrol: slow down. A car speeding at 80mph uses 10% more fuel than one cruising at 70mph, according to the Department for Transport.

What is the best speed for mpg?
The precise number varies by car and environmental conditions, but the sweet spot is generally between 40-60 mph (65-95 km/h). Most small and medium size cars get the best mileage at about 50 mph (80 km/h). A lot of factors affect the fuel economy of your car.
