Overview of proven methods to reduce fuel consumption during long trips. Key factors affecting efficiency at high speeds are discussed.
Author: Radomskyi Maksym VasyliovychLong highway trips can hit your wallet hard, but even with a regular car you can realistically cut fuel consumption by 10–25%. The main thing is to know simple techniques that work for any vehicle – from an old model to a modern crossover. You can also upgrade your car and add functionality by applying tuning, with accessories available in our online store.
Fighting Aerodynamics
On the highway, the main enemy of efficiency is air resistance. The higher the speed, the more fuel is needed to overcome it:
- Optimal speed: Drive at 90–100 km/h. Fuel consumption starts to rise sharply after 110–120 km/h, as overcoming air resistance requires disproportionately more energy.
- Closed windows: Open windows, especially at high speed, create strong aerodynamic drag. It’s better to use the ventilation system or air conditioning than to drive with open windows.
- Remove excess items: Take off roof racks, bike mounts, or boxes if they are not in use. These elements significantly worsen aerodynamics.
Reducing Mechanical Losses
- Tire pressure control: Make sure tire pressure meets the manufacturer’s recommendations. Low pressure increases the contact area and rolling resistance, directly affecting fuel consumption.
- Using cruise control: On a flat road, cruise control keeps the engine running more steadily, ensuring smoother and more economical fuel use.
- Smooth engine braking: When approaching a downhill or traffic light, don’t press the brake immediately—release the gas pedal. Modern fuel-injected engines cut off fuel supply during engine braking, resulting in zero consumption.
These simple actions allow you to travel several dozen kilometers farther on one tank without losing comfort or time.
