Eco-driving in a motorhome: the 5 habits that make a difference

Setting off in a motorhome is all about enjoying that real sense of freedom… but it also means dealing with higher fuel consumption than in a standard car. Heavier, bulkier and sensitive to many factors such as loading, aerodynamics and journey type, this kind of vehicle requires a little a bit of attention if you want to stay economical. Good news! By adopting a few simple eco-driving habits, you can reduce your fuel consumption, protect your budget and travel with peace of mind without ruining any of the fun.

3 key takeaways

•    Smooth, anticipatory driving sharply cuts fuel consumption
•    Vehicle weight and maintenance play a key role
•    Good trip planning will help avoid unnecessary expenditure

Adopt eco-friendly driving habits

Eco-friendly driving means adjusting a few habits at the wheel to reduce fuel consumption, limit your emissions and reduce strain on the vehicle.

Moderate speed and anticipating traffic

Easing off the accelerator is the first habit you should try to develop. A moderate, steady speed will limit consumption spikes and reduce driver fatigue. By anticipating terrain, bends and slowdowns (looking far ahead and reading traffic conditions), you can avoid sharp braking and unnecessary acceleration, two major sources of excess fuel consumption.

Engine braking and finding the correct rev range

On descents, engine braking slows the vehicle naturally (in manual vehicles) without constantly relying on the brakes, thus improving both safety and driving comfort. At the same time, changing gear at the right moment, avoiding over-revving and not holding gear for too long before shifting up will help maintain an efficient rev range and therefore reduce fuel consumption.

Be smart when it comes to motorhome load

An overloaded motorhome uses more fuel, brakes less effectively and is harder to handle. Travelling lighter means greater efficiency and comfort.

Carry only the essentials

Before setting off, sort through your gear: duplicate clothing, “just in case” items, bulky equipment you rarely use… every unnecessary kilo eventually makes its presence felt at the fuel pump. The idea isn't to deprive yourself, but to prioritise the essentials and what actually gets used on board.

Manage water and exterior accessories

A fresh-water tank filled to the brim is very heavy. Adapting how much you fill based on the distance between stops and available water points helps avoid transporting unnecessary weight. Likewise, roof boxes, unused bike racks and exterior accessories increase air resistance. Removing them when not needed helps reduce fuel consumption, especially on motorways.

Did you know ? Every kilo counts

An extra 100 kg in a motorhome can push fuel consumption up by around 0.5 L/100 km.

Service your motorhome regularly

A well-maintained motorhome uses less fuel and remains more reliable over time. Maintenance is an essential part of eco-driving.

Tyre pressure and safety

Under-inflated tyres increase rolling resistance and therefore fuel consumption, while also negatively impacting handling. Checking tyre pressure regularly, based on the actual vehicle weight, is essential. Take the opportunity to check tyre wear and general condition before a long trip.

Keep up with general mechanical servicing

Regular oil changes, fluid checks and clean filters all help the engine to run more efficiently. A clogged air filter or a poorly tuned engine can, on its own, lead to noticeable over-consumption over time. Regular servicing by a professional will help maintain good efficiency.

Manage comfort and equipment wisely

A motorhome is designed for comfort, but some equipment is fuel-hungry. The goal is to enjoy on-board comfort without sending fuel consumption through the roof.

Air conditioning and electrical equipment

Air conditioning is a real plus in summer, but it increases fuel consumption. Use it sparingly, favouring natural ventilation when possible, and avoid running it unnecessarily. On board, solar panels can help power some electrical systems without impacting fuel used for driving.

Switch off the engine when stationary

Letting the engine idle in a car park or outside a shop burns fuel with no benefit. If you’re stopped for more than a short moment, it's better to switch off the ignition and restart when you're ready to set off again. This simple habit avoids “hidden” yet very real consumption that quickly adds up over time.

Plan your trips well

A well-prepared journey means fewer detours, less congestion and less stress. All of this results in more efficient use of fuel.

Choose suitable routes 

Planning your route in advance allows you to favour motorhome-friendly roads, smoother routes with fewer frequent stops. Avoiding city centres, very steep climbs and heavily congested areas helps reduce fuel consumption and makes driving more enjoyable.

Optimise refuelling and limit short trips

Using fuel price comparison apps helps you to fill up at the right time and at the best price. As far as possible, also avoid repeating short urban journeys with a cold engine. On those short urban runs, the engine doesn't reach its optimal efficiency and uses more fuel.

Eco-driving in a motorhome ultimately comes down to finding the balance between enjoyment and common sense. By adjusting your driving style, reducing weight, maintaining your vehicle properly and planning your journeys, you quickly make real savings while increasing your peace of mind. And to start off on the right foot, choosing a well-maintained vehicle like those offered on Evasia.fr is an excellent starting point for a smoother, more controlled journey.

FAQ

•    What is the average fuel consumption of a motorhome ?
It is generally between 8 and 12 L/100 km, depending on the model, the weight and your type of trip.

•    Why does my motorhome use too much fuel ?
Overloading, aggressive driving, poorly inflated tyres or insufficient maintenance are often to blame.

•    How do I calculate my fuel consumption in L/100 km ?
Divide the litres used by the kilometres driven, then multiply by 100.

•    What alternatives are there to reduce fuel dependency ?
Bioethanol or some conversion kits have limited compatibility. Solar panels mainly help to reduce on-board electricity use, not driving-related fuel consumption.
