How to Drive an Automatic Transmission Car for Fuel Efficiency?

[StJuliana]

Here are some methods to save fuel with an automatic transmission: 1. Calculate the most economical speed: Different engine displacements have different "economical speeds" when driving on highways, which is the speed at which the car consumes the least fuel. Drive on the highway several times and pay attention to the average fuel consumption value on your car. Once you find this "sweet spot," cruise at this speed to maintain the most comfortable fuel consumption state. 2. Develop good driving anticipation to reduce unnecessary sudden braking and acceleration: Develop good driving anticipation to minimize unnecessary sudden braking and acceleration. Smoothly accelerate and shift gears frequently to keep the transmission in its optimal working condition. 3. Shift to N gear at traffic lights: Many drivers tend to keep the car in D gear and hold the brake when waiting at a red light, releasing the brake to move when the light turns green. This is an incorrect practice because keeping the car in D gear increases clutch friction. Shifting to N gear while waiting at a red light not only saves fuel but also allows you to take your foot off the brake on flat roads, reducing fatigue.

I've been driving automatic transmission cars for years and would like to share some fuel-saving tips. The key to saving fuel lies in maintaining smooth driving habits. Avoid pressing the accelerator too hard when starting, allowing the transmission to shift up gradually for better efficiency. On highways, keeping the speed around 80 km/h is the most economical—going too fast increases wind resistance and fuel consumption. I always anticipate road conditions, easing off the accelerator early to coast and minimizing sudden braking. Avoid carrying unnecessary items in the car; clear out unused clutter from the trunk to reduce weight. Using the air conditioning significantly increases fuel consumption, especially in summer—opening the windows might be more economical. Turn off the engine if parked for long instead of idling; warming up the car for 30 seconds is sufficient. Regular maintenance is crucial—check tire pressure periodically, as low pressure increases rolling resistance and fuel consumption. Adopting these habits can save a lot on fuel costs and is also environmentally friendly.
