19 MPG combined is what you should realistically expect from a 2022 Land Rover Defender 90 with the mild-hybrid 3.0L inline-six engine. This figure separates those needing a serious off-roader from those primarily concerned with appearances. This isn’t a vehicle bought for low fuel costs; it’s a statement, a tool, and a lifestyle choice. The 90’s short wheelbase prioritizes agility on challenging terrain over aerodynamic efficiency on the highway, and its strong build reflects a “go anywhere” attitude more important than saving money at the pump.

City and highway performance

The EPA estimates 17 MPG in the city and 22 MPG on the highway, ratings which accurately reflect the trade-offs in the Defender 90’s design. Stop-and-go city driving means the engine operates under its thirstiest conditions, made worse by the vehicle’s weight and short gearing. On the highway, that turbocharged inline-six has room to breathe, and the mild-hybrid system helps during cruising. Still, the upright, boxy shape of the Defender isn’t aerodynamic, and wind resistance noticeably affects fuel consumption at higher speeds. This is a stark contrast to sleek crossovers designed for fuel efficiency.

Annual fuel cost

Owners of the 2022 Land Rover Defender 90 MHEV 3.0L can expect to spend approximately $3,050 per year on fuel. The EPA calculates this based on driving 15,000 miles annually, using national average fuel prices. Note that this is an estimate, and individual spending will vary based on driving habits, local fuel costs, and city versus highway driving ratios.

Real-world expectations

The EPA provides a standardized benchmark, but real-world fuel economy often differs depending on driving style, terrain, and even tire choice. Defender 90 owners who frequently go off-road, with its slower speeds and higher engine loads, will likely see numbers closer to the city rating, even lower. Aggressive acceleration, frequent hard braking, and prolonged idling all decrease fuel efficiency.

Conversely, a predominantly highway commute, driven with a light foot, might yield results closer to, or even slightly above, the EPA’s 22 MPG estimate. It’s a vehicle that rewards smooth, measured inputs, but rarely gets exceptional mileage.

How it compares

When compared to other off-road-capable SUVs, the Defender 90’s fuel economy is within the expected range. A Jeep Wrangler Unlimited with the 2.0L turbocharged four-cylinder gets about 22 MPG combined, while the V6 version dips slightly lower. The Toyota 4Runner, struggles to achieve even 17 MPG combined. Considering a comparable premium SUV, the BMW X3 M40i achieves a respectable 23 MPG combined, better than the Defender’s 19 MPG. However, the Defender is designed for a different job than the BMW ROVER MPG across all years, prioritizing off-road capability and ruggedness over efficiency.

Tips to maximize efficiency

Tire inflation is important. Ensure your tires are inflated to the pressure specified on the doorjamb sticker. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel, especially since Defender 90 owners often switch to more aggressive off-road tires, this is even more crucial.

Avoid unnecessary idling. The Defender’s engine consumes fuel even when stationary. Shutting off the engine during extended stops, like waiting in a parking lot, can significantly reduce fuel waste. The mild-hybrid system assists with smooth restarts.

Maintain a smooth and consistent driving style by avoiding aggressive acceleration and hard braking. Anticipate traffic flow and maintain a steady speed whenever possible. The turbocharged engine is responsive, but using its full power frequently will negatively impact fuel consumption. Consider all Land fuel economy data too.

Regular maintenance is critical. Ensure that the engine is properly tuned and that all filters are clean. A well-maintained engine operates more efficiently and consumes less fuel. Pay particular attention to the air filter, as a clogged filter restricts airflow and reduces engine performance.

Minimize roof rack use because, while the Defender 90 can be accessorized in many ways for any adventure, a roof rack increases aerodynamic drag, especially at highway speeds. Removing it when not needed can noticeably improve fuel economy.
