The most fuel-efficient speed for highway driving is typically between 55 and 60 miles per hour (88 and 96 kilometers per hour). At these speeds, the engine operates at its most efficient point, and wind resistance is relatively low. However, if you are willing to sacrifice a bit of fuel economy, you can usually drive at a slightly higher speed without significantly impacting fuel consumption. For example, driving at 65 mph (104 km/h) will usually only reduce your fuel economy by about 5-10%.
Here are a few tips for conserving fuel while driving on the highway:
- Accelerate gradually.
- Maintain a steady speed.
- Avoid sudden braking.
- Use cruise control if possible.
- Keep your tires properly inflated.
- Remove any unnecessary weight from your vehicle.
- Use a fuel-efficient car.
By following these tips, you can save fuel and money on your next road trip.
