18 MPG combined is what you’d expect from the 2025 Land Rover Range Rover LWB MHEV 4.4L 8-cylinder, a magnificent, long-wheelbase luxury SUV powered by a twin-turbo V8. Buyers of this vehicle aren’t measuring their existence by miles per gallon; they’re measuring it in effortless power, sumptuous comfort, and undeniable presence. This isn’t a commuter car built for hypermiling; it’s a statement, a mobile sanctuary that happens to transport its occupants with supreme confidence across any terrain, or simply from a heliport to a chalet. The fact that it achieves even this figure with its substantial curb weight and strong powertrain speaks to the underlying engineering prowess, an indication of Jaguar Land Rover’s commitment to excellent, albeit thirsty, performance.

City and highway performance

Breaking down that combined figure, the Range Rover LWB MHEV 4.4L delivers 16 MPG in the city and 22 MPG on the highway. In urban environments, that 16 MPG is a direct consequence of moving nearly three tons of luxury, often from a standstill. The twin-turbo V8, while incredibly smooth and powerful, does have to work to overcome inertia, and stop-and-go traffic will naturally demand more fuel. The Mild Hybrid Electric Vehicle (MHEV) system does provide some assistance here, subtly smoothing out starts and stops, and recovering a modicum of energy through regenerative braking. However, it’s not a full hybrid by any stretch; its role is more about refinement and marginal gains than transformative efficiency.

On the open road, the 22 MPG highway rating becomes more achievable. Once at cruising speed, the big V8 operates within its most efficient range. The smooth 8-speed automatic transmission is adept at keeping revs low, and the vehicle’s aerodynamic profile, surprisingly sophisticated for its boxy heritage, helps to cleave through the air with less resistance than one might expect. Long-distance cruising is this vehicle’s natural habitat, where its immense power reserve translates into effortless overtaking and sustained high speeds without strain. For an all Land fuel economy data enthusiast, it’s clear this vehicle prioritizes commanding performance on the open road.

Annual fuel cost

The EPA estimates an annual fuel cost of $3,200 for the 2025 Range Rover LWB MHEV 4.4L 8-cyl. This figure is based on specific assumptions: driving 15,000 miles per year, with a split of 55% city driving and 45% highway driving, and using national average fuel prices, which for premium unleaded are inherently subject to fluctuation. It’s a useful benchmark for buyers who understand that luxury and performance come at a price, and that premium fuel is a consistent entry on their expense sheet. For those considering a ROVER MPG across all years, this context is crucial. The annual fuel cost is simply another line item in the budget of someone who can comfortably afford the six-figure price tag of this SUV, not a deal-breaker. It’s part of the ownership experience.

Real-world expectations

In the real world, owners of the Range Rover LWB MHEV 4.4L often exceed the EPA’s 15,000-mile annual average, particularly if the vehicle is used for extended trips to second homes or estates. Aggressive driving, with frequent deployment of that magnificent twin-turbo V8, will naturally push fuel consumption higher than the EPA estimates. Conversely, a disciplined driver, using cruise control on long highway stretches and anticipating traffic in urban environments, might slightly exceed the highway figure. What’s guaranteed, however, is a driving experience defined by immense power and unwavering composure, a trade-off many are more than willing to make for the privilege of Range Rover ownership.

The mission of this vehicle is not frugality. It is about arriving anywhere, in any weather, with unparalleled grace and power. Pondering its fuel economy too deeply misses the point entirely. The demographic for this £150,000+ luxury SUV typically has other concerns regarding their financial outlay; fuel costs, while present, are simply part of the operational expenditure for a vehicle that fulfills a very specific, high-end lifestyle requirement. They want the best, and the Range Rover delivers, fuel consumption be damned.

How it compares

When stacked against its direct rivals, the Range Rover LWB MHEV 4.4L’s 18 MPG combined figure places it squarely in line with its V8-powered, long-wheelbase peers. A Mercedes-Benz GLS 580, powered by a 4.0L twin-turbo V8 with EQ Boost, also achieves a similar 18 MPG combined (16 City/21 Highway), demonstrating that luxurious V8 power in this class inevitably results in comparable consumption. The BMW X7 M60i, with its 4.4L twin-turbo V8 and MHEV tech, offers 17 MPG combined (15 City/21 Highway), marginally less efficient but still very close. Even the Bentley Bentayga V8, despite its more exclusive badge, clocks in at 17 MPG combined (14 City/23 Highway). This isn’t a realm where one vehicle dramatically outperforms another in terms of efficiency; it’s a field of powerful, opulent behemoths delivering similar fuel figures. The buyer is looking for brand cachet, bespoke luxury, and a specific driving dynamic, not a marginal MPG advantage.

Tips to maximize efficiency

Use the vehicle’s adaptive cruise control on highways to help maintain a consistent speed, reducing unnecessary acceleration and deceleration that consume more fuel. The Range Rover’s system is particularly adept at smooth operation, which benefits efficiency on longer trips.

Ensure your tires are always correctly inflated to the manufacturer’s recommended pressures. Under-inflated tires increase rolling resistance, forcing the engine to work harder and thus consume more fuel. A few PSI can make a measurable difference over time.

Anticipate traffic flow and avoid aggressive driving whenever possible. Hard acceleration and sudden braking events place significant demands on the 4.4L V8, negating the subtle efficiency benefits of the MHEV system. Smooth inputs are key to maximizing fuel economy in any vehicle, but especially one with this much power.

Use the vehicle’s various drive modes. While Dynamic mode is exhilarating, it sharpens throttle response and holds gears longer, which is counterproductive to fuel efficiency. Eco mode, when available or if using a custom setting, can soften throttle mapping and optimize transmission shifts for better economy during routine driving.

Keep up with the recommended service schedule. A properly maintained engine, with clean air filters, fresh engine oil, and correctly functioning spark plugs, operates more efficiently than one that is neglected. This ensures the powerful 4.4L V8 can perform optimally without wasting fuel.
