20 MPG combined is what you get with the 2024 Land Rover Defender 90 MHEV 3.0L 6-cyl. Anyone familiar with the Defender knows what it’s about: a highly capable off-roader with premium features. This vehicle isn’t built for maximum efficiency; it’s designed to handle tough terrain, which means fuel consumption. Even with the mild-hybrid system, a compact SUV weighing over 4,700 pounds is still affected by physics.

City and highway performance

The EPA estimates offer more detail: 18 MPG in the city and 22 MPG on the highway. The lower city MPG reflects stop-and-go driving. The highway figure is slightly better because consistent speeds help the mild-hybrid system. However, the Defender’s aerodynamics, which are more like a brick, and permanent four-wheel drive hurt its fuel economy, even on the open road.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,900 for the 2024 Land Rover Defender 90 MHEV. This is based on 15,000 miles per year and national average fuel prices. This is what you can expect to pay annually. If you drive significantly more than 15,000 miles annually, or if fuel prices are higher in your area, expect that figure to increase. If you drive less and prices are low, it will decrease. $2,900 is the benchmark for yearly fuel expense.

Real-world expectations

EPA estimates are a benchmark, but real-world fuel economy varies. Driving style, terrain, and weather all matter. Driving aggressively off-roading frequently, or driving at high speeds will lower MPG. Cold weather can reduce fuel efficiency because of higher engine load and heating systems. To save fuel, drivers should drive mindfully, avoiding hard acceleration and keeping consistent speeds.

How it compares

The Defender 90 performs as expected compared to other off-road SUVs. The Jeep Wrangler Unlimited Sahara with its 2.0L turbo engine gets around 22 MPG combined, which is slightly better, but its on-road handling isn’t as good. The Toyota 4Runner, a favorite, gets just 17 MPG combined with its older V6 engine. Land Rover’s lineup also varies; check ROVER MPG across all years for a historical comparison to current Land Rover vehicles. And you can see all Land fuel economy data across their brand. The Lexus GX 460, another truck-based SUV, is around 16 MPG combined. Defender 90 buyers know this. They aren’t looking at hybrid crossovers; they want its off-road capability, boxy styling, and premium features, and 20 MPG is part of that.

Tips to maximize efficiency

Use the mild-hybrid system. The electric motor helps the engine accelerate and allows engine-off coasting, both of which save fuel. Watch the instrument panel display, which shows real-time energy flow and efficiency, and adjust your driving.

Keep your tires inflated to the correct pressure. Land Rover specifies tire pressures for on-road performance and fuel economy. Following these recommendations can help. Underinflated tires increase rolling resistance, making the engine work harder and use more fuel. Check tire pressures often, especially when the temperature changes.

Reduce weight. Extra cargo reduces fuel efficiency. Remove items you don’t need every day, such as sporting equipment or tools. A lighter vehicle needs less energy to accelerate and keep its speed.

Plan routes. Avoid heavy traffic or frequent stops, as these reduce fuel economy. Use navigation to find and avoid delays. Choose routes with consistent speeds and minimal braking.

Consider the driving mode selector. The Defender 90 has driving modes for different conditions. Off-road modes prioritize traction, but they can increase fuel consumption. Select the best mode for the situation to balance performance and efficiency.
