The 2023 Land Rover Defender 90 MHEV with the 3.0L inline-six gets 20 MPG combined. While not frugal, this is acceptable, even expected, for a short-wheelbase SUV that prioritizes off-road capability and rugged style over fuel efficiency. The Defender 90 is for those who value capability and image and are willing to pay extra at the pump.

City and highway performance

EPA estimates for the 2023 Defender 90 MHEV with the 3.0L engine are 18 MPG in the city and 23 MPG on the highway. The city rating reflects the engine’s higher fuel consumption during stop-and-go driving, common for urban drivers drawn to the Defender’s appeal. The highway rating reveals the impact of the vehicle’s boxy shape and permanent four-wheel-drive system on aerodynamic efficiency. Expect the highway MPG to drop at higher speeds, especially with headwinds.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Land Rover Defender 90 MHEV 3.0L is $2,900. This is based on driving 15,000 miles per year and using national average fuel prices. However, drivers who frequently go off-road, drive aggressively, or live in areas with higher fuel prices could see this number increase. Factor in potential fuel price fluctuations, as they can greatly impact your annual spending.

Real-world expectations

Real-world fuel economy often varies from EPA estimates. Defender 90 owners should anticipate slightly lower numbers than the official ratings, especially with spirited driving or challenging terrain. Tire choice and load weight also matter. Larger, more aggressive off-road tires will reduce fuel economy compared to the stock tires. The Defender 90 has little storage space in the rear cargo area, so owners may mount cargo on the roof, which will also lower fuel economy.

How it compares

The Land Rover Defender 90 MHEV’s fuel economy places it within a specific segment of SUVs. Compared to a Jeep Wrangler Unlimited Sahara 4×4 (20 MPG combined) or a Ford Bronco 4-Door with the 2.3L EcoBoost (20 MPG combined), the Defender offers similar fuel efficiency. A Toyota 4Runner, known for its off-road ability but less so its efficiency, achieves only 17 MPG combined. For better fuel economy in a smaller package, consider a Lexus NX 350h (39 MPG combined), but it lacks the Defender’s rugged charm and off-road capability. Drivers prioritizing fuel efficiency may not choose the Defender. These are tradeoffs that Defender buyers accept.

Tips to maximize efficiency

Gentle acceleration and consistent speeds affect the Defender 90’s fuel economy. While the supercharged inline-six likes to be revved, aggressive driving will quickly deplete the fuel tank. Try using “Eco” mode, which dulls the throttle response, encouraging a more relaxed driving style. You won’t unleash the car’s full potential, but you will see a modest MPG improvement.

Proper tire inflation is critical for fuel economy. Check the tire pressure regularly and maintain the recommended levels, found on the door jamb or in the owner’s manual. Underinflated tires increase rolling resistance, leading to higher fuel consumption. Remember to adjust tire pressures for off-road driving, and then return them to the correct on-road pressures when you’re done.

Minimize unnecessary weight. Removing unneeded items from the vehicle reduces the load on the engine, improving fuel efficiency. A roof rack creates drag and will reduce fuel economy, so only install one when needed. If you have the dealer-installed winch, consider whether you really need to haul around that extra weight constantly.

Plan trips strategically to minimize stop-and-go driving. Congested roads and frequent stops burn more fuel. Consider using GPS navigation to find routes with less traffic. Longer routes can be more fuel-efficient if they maintain a more consistent speed. The Defender’s tall profile and soft suspension lead to added braking distance, so start braking sooner than you might in a lower car.
