As drivers, we are all looking for ways to save money at the gas pump. One way to achieve fuel savings is by driving at the most fuel-efficient speed. So, what is the most fuel-efficient speed to drive your car?

According to the US Department of Energy, the most fuel-efficient speed for most vehicles is around 50-60 miles per hour (mph). This is because at this speed range, the engine is operating at its peak efficiency and using less fuel to maintain speed.

Driving slower than 50 mph may not necessarily improve fuel efficiency as the engine is not operating at its most efficient level. However, driving faster than 60 mph can significantly decrease fuel efficiency. For every 5 mph increase in speed above 60 mph, fuel efficiency decreases by roughly 7%.

To put it in perspective, let’s say you drive at 70 mph instead of 60 mph on a highway for a distance of 100 miles. Your fuel efficiency could drop by 10-15%, which could cost you an extra $5-10 in gas money.

Driving at a steady speed can also contribute to better fuel efficiency. Constantly accelerating and braking can decrease fuel efficiency as it puts more strain on the engine. Maintaining a steady speed helps the engine to run more smoothly and use less gas.

Another factor to consider when trying to maximize fuel efficiency is the road conditions. Driving on hilly or winding roads can decrease fuel efficiency as the engine has to work harder to maintain speed. Plan your route accordingly and try to avoid routes with excessive inclines or sharp turns.
