Off-roading is a huge amount of fun, but it’s no secret that 4×4 vehicles aren’t exactly known for their fuel efficiency.
The rugged builds, larger tyres, and added weight can take a toll on your mileage, but that doesn’t mean you can’t optimise your vehicle for better fuel economy. By combining the right accessories with smart driving techniques, you can significantly improve your 4×4’s fuel efficiency while still enjoying those off-road adventures.
Here’s how to get the best out of your 4×4’s fuel consumption without sacrificing performance.
Optimising Aerodynamics with Slim Roof Racks
Why it matters: Aerodynamics play a big role in fuel efficiency, especially at higher speeds. Roof racks, while useful for carrying gear, can create additional drag that increases fuel consumption by making the engine work harder. The larger and bulkier the roof rack, the greater the drag.
Solution: Opt for low-profile or slim roof racks that sit closer to the roof of your 4×4. These racks provide storage space without significantly increasing the vehicle’s aerodynamic resistance. Some newer designs also have streamlined shapes, specifically engineered to minimise drag. If you don’t need the roof rack for a particular trip, consider removing it completely to reduce wind resistance and improve fuel efficiency.
Key Tip: When not in use, remove extra cargo from the roof rack to further reduce weight and drag. An empty rack still adds resistance and impacts fuel economy.
Weight-Saving Modifications: Less is More
Why it matters: The heavier your 4×4, the more power it needs to move, which burns more fuel. Off-road vehicles often carry heavy-duty parts and equipment that add weight, but some of these components can be swapped for lighter alternatives without compromising performance.
Solution: Consider investing in lightweight accessories like aluminium skid plates, alloy wheels, or synthetic winch ropes. These materials are durable but significantly lighter than their steel counterparts. Another easy modification is to reduce the weight of unnecessary gear when not on off-road trips. Tools, extra fuel tanks, or spare parts you don’t need for a daily drive add weight and cost you fuel.
Key Tip: Every 100 pounds of weight you remove from your vehicle can improve fuel efficiency by about 1-2%. Over time, this can translate into noticeable savings, especially on longer trips.
Choosing the Right Tires for Fuel Efficiency
Why it matters: Tyres play a crucial role in fuel economy due to rolling resistance—the force needed to keep your tyres moving on the road. Off-road tyres, particularly mud-terrain ones, are typically larger, heavier, and more aggressive, which increases rolling resistance and lowers fuel efficiency.
Solution: For daily driving or mixed terrain use, consider using all-terrain tyres that strike a balance between off-road performance and on-road fuel efficiency. All-terrain tyres generally have less aggressive tread patterns, making them lighter and more fuel-efficient. Additionally, choosing low-rolling resistance tyres specifically designed for fuel efficiency can offer smoother handling and better mileage on paved roads without compromising off-road capabilities.
Key Tip: Keep your tyres properly inflated. Under-inflated tyres increase rolling resistance, reduce fuel efficiency, and wear down faster. Regularly checking and maintaining the correct tyre pressure can improve fuel efficiency by up to 3%.
Smart Driving Techniques to Complement Fuel-Saving Accessories
Why it matters: Even with the best fuel-efficient accessories, poor driving habits can still drain your tank quickly. How you drive can have a bigger impact on fuel economy than you might realise, especially when driving a heavy, off-road-ready 4×4.
Solution: Adopt these fuel-saving driving habits:
- Smooth Acceleration and Braking: Aggressive starts and sudden stops consume more fuel. Gradual acceleration and slowing down in anticipation of stops can help reduce fuel consumption.
- Cruise Control on Highways: Using cruise control on flat terrain helps maintain a consistent speed, reducing the engine workload and saving fuel.
- Reduce Idling Time: Idling burns fuel without moving the vehicle. Try to minimise idling by turning off your engine when stopped for longer periods.
- Maintain Moderate Speeds: While it’s tempting to push your 4×4 to the limit, higher speeds increase air resistance and fuel consumption. Stick to moderate speeds to get the best out of your vehicle’s fuel economy.
Key Tip: Using the correct driving mode can also help. Some 4×4 vehicles have fuel-saving modes that optimise engine output for better fuel economy when you’re not off-roading. Use these modes on paved roads for a fuel-efficient drive.
All the Fuel Efficiency Without Sacrificing Performance
Improving your 4×4’s fuel efficiency is all about finding a balance between performance and practical savings. By focusing on aerodynamics, reducing unnecessary weight, selecting the right tyres, and adopting smart driving techniques, you can enjoy both fuel efficiency and off-road prowess. Each small change can add up to significant savings over time, making it easier on your wallet and the environment.
Remember, every drop of fuel counts, so make the most of your 4×4 with these practical tips. And the best part? You don’t have to sacrifice the excitement of off-roading to enjoy a more fuel-efficient vehicle.
