19 MPG combined is what you should expect if you’re considering the 2020 Land Rover Defender 90 with its 2.0L four-cylinder engine. This figure isn’t going to win any awards, nor will it sway committed Prius drivers. But the Defender 90 isn’t trying to be thrifty. It’s a boxy, capable off-roader with a premium badge, and for those who value presence and go-anywhere ability over fuel sipping, it’s a tradeoff they’re willing to make.

City and highway performance

The EPA estimates suggest 18 MPG in the city and 21 MPG on the highway. These figures reflect the Defender’s aerodynamic profile (or lack thereof) and the demands placed upon its engine to haul a vehicle that, even in its shorter 90 guise, still weighs over 4,600 pounds. The eight-speed automatic transmission does its best to keep the engine in its sweet spot, but acceleration, particularly at higher speeds, demands a heavy foot, further impacting fuel consumption. Those expecting hybrid-like efficiency during their daily commute will be disappointed. However, highway driving can yield slightly better results if a consistent speed is maintained and aggressive overtaking is avoided.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2020 Land Rover Defender 90 2.0L at $3,050. This figure is based on driving 15,000 miles per year and using the national average fuel price for regular unleaded gasoline. It’s important to remember that this is merely an estimate. Real-world fuel costs can vary significantly depending on driving habits, local fuel prices, and the type of terrain encountered. Someone who primarily drives in stop-and-go traffic will likely exceed this estimate, while someone who does mostly highway driving might see slightly lower costs.

Real-world expectations

Do not expect to achieve the EPA numbers consistently in real-world conditions. The Defender 90’s boxy shape and off-road-oriented tires create significant aerodynamic drag. And the temptation to exploit the engine’s power, along with the added weight of any aftermarket modifications and off-road equipment owners often add, will further decrease fuel economy. A lead foot, combined with city driving, will likely see numbers dip into the low teens. The 21 MPG highway figure is achievable, but requires conscious effort and a light touch on the accelerator.

How it compares

Compared to other off-road-focused SUVs, the Defender 90’s fuel economy is predictably lackluster. The Jeep Wrangler Unlimited Sahara with the 2.0L turbo engine manages around 22 MPG combined, showing that even boxy SUVs can achieve slightly better efficiency. A Toyota 4Runner, while known for its reliability, only manages around 17 MPG combined, making the Defender look somewhat reasonable in comparison. It’s also worth noting that the more powerful six-cylinder Defenders will consume even more fuel.

Ultimately, selecting the Defender is a deliberate choice to prioritize off-road capability and a distinctive design over outright fuel efficiency. You can find all Land Rover fuel economy data on our site, showing the range of consumption across their lineup.

Tips to maximize efficiency

Proper tire inflation is critical. The Defender 90 often runs on off-road-oriented tires, which can lose pressure more quickly. Regularly check and maintain the recommended tire pressure to minimize rolling resistance and improve fuel economy. A properly inflated tire makes a tangible difference, especially on a heavy vehicle like the Defender.

Avoid aggressive acceleration and braking. The Defender 90 is not a sports car, and trying to drive it like one will only result in a significant decrease in fuel economy. Smooth and consistent driving habits will help the engine operate more efficiently and reduce unnecessary fuel consumption. A calm, measured approach behind the wheel is key.

Minimize unnecessary weight. Carrying extra cargo adds to the vehicle’s overall weight and increases fuel consumption. Remove any unnecessary items from the vehicle, especially heavy gear, to improve fuel efficiency, particularly during city driving. Consider taking off any roof racks or accessories when not in use, as these increase drag.

Plan your routes strategically. Avoid areas with heavy traffic congestion and opt for routes that allow for consistent speeds. Stop-and-go traffic is a major fuel economy killer, especially for a vehicle as heavy as the Defender. Planning ahead can make a difference.

Consider the driving mode. The Defender offers various driving modes, some of which are designed for off-road use. Ensure that you are in the appropriate driving mode for the conditions. Using off-road modes on pavement will increase fuel consumption needlessly. To see the broader range of ROVER MPG across all years, check out our pages for more detail.
