How can eco-driving help you save fuel?

Tips & Advice for Car, SUV & Van tyres

These days, there is a growing interest in "eco-driving” or “green driving” techniques. Here we take a look under the hood of the eco-drive meaning, and how certain driving behaviours can not only help the environment but also save money on your fuel budget.

What is eco-driving?

The “eco” of eco-driving stands for two principles:

  • Firstly, ecology: driving with the environment in mind is increasingly important for consumers these days.
  • Secondly, economical: saving fuel has a positive effect on a driver’s wallet. Eco-driving, or “green driving”, is thereby an ensemble of driving techniques that aim to reduce emissions and the use of fossil fuels as much as possible. And if you drive an electric vehicle, it will also help you increase the battery range!

What driving techniques can help save fuel?

Here are 9 Eco-driving tips to reduce your carbon footprint and save money.

1. Check your tyre pressure

Under-inflated tyres increase fuel consumption, in addition to impacting the driver's control of the vehicle. On the other hand, over-inflated tyres reduce fuel consumption but increase braking distances and reduce tyre life. Indication of appropriate pressure levels can usually be found in the vehicle's maintenance manual, the glove box, on the door, or the fuel door.

2. Choose the right tyre

“Fuel efficient tyres” designed to generate low rolling resistance can also significantly reduce your car’s fuel consumption. A labelling system can help you identify the most efficient tyre: look for the “gas pump” pictogram on the label and choose tyres with an A rating.

The label displays the tyre fuel efficiency, rated from A to E (A being most efficient)

3. Anticipate: slow down, don’t brake

For example, avoid racing up to traffic lights and hitting the brakes. Instead, plan ahead and allow enough distance to let the car gently decelerate in time.

4. Avoid jolted driving

Not always easy in built-up urban areas, but constant stopping and starting will take its toll on your fuel consumption. One of the ways to get better mpg (miles per gallon) when city-driving is to relax! You don’t need to be constantly bumper-to-bumper with the car in front. Luckily, these days many vehicles are equipped with urban driving modes designed to reduce fuel consumption

5. Avoid sudden accelerations

The faster you change an object’s velocity, the more force it takes. A sudden increase in speed will therefore require an extra dose of energy, and therefore tax your fuel supply.

6. Stick to speed limits

Not just imposed for safety reasons, car speed limits help reduce fuel consumption and pollutant emissions.

7. Read the terrain

Cruising in gear can be a great way to get better mpg. If you’re approaching a decline, for example, let your car cruise and gravity do its job. If there’s an incline just after, start accelerating as you reach the bottom of the slope. What about cruise control? While useful for the motorway, it’s best to turn it off on hilly terrain.

8. Don’t leave the engine running

For both your wallet and the environment, avoid leaving the car running if not necessary. This includes stopping to make a phone call, waiting in the car to pick up the kids, even sitting in heavy traffic.

9. Use air conditioning sparingly

Unnecessary use means more fuel consumed and more CO₂ in the atmosphere. At low speed, prefer ventilation or lower the windows.

Green driving: expert tips to help you save fuel

Cyrille Roget, Technical and Scientific Communications Director for Michelin, has some specific examples of how to save fuel with eco-driving techniques.

He explains, “Accelerate gently, making use of the car’s power for example when starting up.” There’s no need to roar off as fast as possible. Likewise, when it comes to speed: “Respect speed limits on the motorway to save fuel. Don’t necessarily accelerate uphill, you can always let the car slow a little on inclines.”

In urban areas, Cyrille says, “the temptation is to stay close behind the person in front. In certain cities, people can develop a jumpy driving style. But the key is to stick to your own rhythm, and to anticipate as much as possible.”

And one of the most important factors when it comes to saving fuel and getting the most out of your miles per gallon (mpg)? Tyres! Cyrille explains that a lot of the “wasted” energy (fuel that isn’t used to turn the wheels of the car) is lost due to rolling resistance: “This loss represents up to 20%, in other words one full tank in five. And when you consider how much fuel we put in a car every year, you understand it’s a significant amount.”

The solution to reducing rolling resistance (without losing traction) is in the right tyres. Take the new MICHELIN e·PRIMACY tyres, for example. Specifically designed with all the aspects of eco-driving in mind, they help drivers save fuel and money due to exceptionally low rolling resistance(1).

With the best rolling resistance vs. the average premium competitors(1), MICHELIN e·PRIMACY offers 0.21 litres of fuel per 100 kilometres and around €80 over the life of the tyre(2,3). For an electric vehicle, range is increased by an estimated 7% compared to other tyres of its category – that’s 30km, for an estimated 400km range(4).

How can drivers help the environment?

The automotive industry is making significant steps towards improving vehicles’ impact on the environment through innovations such as the MICHELIN e·PRIMACY tyre or the MICHELIN PILOT SPORT EV tyre. But the driver also has a significant role to play. As we’ve seen, eco-driving is not only a way to save fuel, money and stay safer on the road, but the mindset of green driving is also fundamental if we are, together, rolling towards a greener future.
