20 MPG combined won’t make the 2023 Land Rover Defender 110 MHEV a fuel-sipping champion. Let’s be realistic, though: this isn’t a vehicle purchased by someone obsessing over maximizing MPGs. It’s bought by individuals who prioritize reliable capability, iconic design, and undeniable presence. The mild hybrid system provides a boost, but you’re hauling around a lot of weight and pushing a lot of air, which requires fuel.

City and highway performance

The EPA estimates that the Defender 110 MHEV achieves 18 MPG in the city and 23 MPG on the highway. These figures reflect the demands placed on the 3.0L turbocharged inline-six engine and its 48-volt mild hybrid system in different driving environments. City driving involves frequent acceleration and deceleration, putting a strain on fuel consumption. The highway figure fares slightly better because the engine can settle into a more efficient cruising speed. However, the Defender’s boxy shape and all-terrain tires contribute to increased aerodynamic drag, impacting efficiency even during highway driving.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2023 Land Rover Defender 110 MHEV is $2,900. This figure is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs will vary depending on your driving habits, the type of driving you do, and the price of gasoline in your area. The $2,900 figure provides a standardized benchmark for comparing fuel costs across different vehicles. Consider it the cost of admission for owning a vehicle with this level of off-road prowess and unmistakable style.

Real-world expectations

While the EPA provides a useful baseline, real-world fuel economy often deviates from these official figures. Defender 110 owners report variations based on driving style, load, terrain, and the use of accessories like roof racks or off-road tires. Owners frequently engaging in off-road adventures or towing can expect to see their fuel economy dip below the EPA estimates. Conversely, those primarily using the Defender for city or highway commutes might achieve slightly better MPG, however, temper your expectations. This is a heavy, capable vehicle, and its fuel consumption will reflect that regardless of how carefully you drive.

How it compares

Several competitors offer similar levels of off-road capability, but their fuel economy varies. The Jeep Wrangler Unlimited, depending on the engine choice, can offer slightly better or worse fuel economy. For instance, the Wrangler Unlimited with the 2.0L turbo engine manages around 22 MPG combined, while the V6 hovers around 19 MPG. The Toyota 4Runner, a long-time rival, achieves a dismal 17 MPG combined. Even the more luxurious BMW X5 xDrive40i manages a better 23 MPG combined, but it lacks the Defender’s go-anywhere capability. If you want to explore ROVER MPG across all years or all Land fuel economy data, this will also inform your decision.

Tips to maximize efficiency

While the Defender 110 MHEV isn’t known for its exceptional fuel economy, there are steps you can take to improve its efficiency. Ensure your tires are properly inflated to the recommended pressure. Underinflated tires increase rolling resistance, leading to higher fuel consumption, so keep them at the pressure listed on the door jamb sticker.

Minimize unnecessary weight inside the vehicle. Remove any items you don’t need, as extra weight directly impacts fuel economy. This is important if you frequently carry heavy gear or equipment.

Avoid aggressive driving habits such as rapid acceleration and hard braking. Smooth, consistent driving helps to conserve fuel. The Defender’s mild hybrid system assists with stop/start, but it is important to drive with smooth inputs from the pedals.

When possible, use cruise control on the highway to maintain a constant speed and reduce fuel consumption. Even small fluctuations in speed can decrease MPG efficiency, so set the system and let it work.

Consider limiting the use of accessories that drain power, such as air conditioning. While comfort is important, running the A/C at full blast constantly can reduce fuel economy. Every little bit helps.
