21 MPG combined for the 2025 Land Rover Range Rover P400 MHEV 3.0L 6-cyl is more than a number; it outlines the vehicle’s specific engineering achievements and its pursuit of luxury and capability. This isn’t a vehicle designed to win economy runs. Instead, this figure points to Land Rover’s commitment to improving efficiency where possible without changing the Range Rover’s essential nature – that of a commanding, very refined, and highly capable ultra-luxury SUV. The Range Rover buyer accepts this MPG not because they are indifferent to fuel costs, but because they understand that luxury involves power, quiet comfort, and the ability to traverse any terrain, all while maintaining a respectable balance at the pump for such an imposing machine.

City and highway performance

Looking at the specifics, the P400 MHEV’s 19 MPG in the city and 24 MPG on the highway paint a clearer picture of its consumption. For a vehicle that often finds itself navigating urban landscapes with grace, the 19 MPG city rating is impressive. This is where the mild-hybrid electric vehicle (MHEV) system truly helps, subtly assisting the powerful 3.0L inline-six cylinder engine during stop-and-start traffic and low-speed maneuvering. The smooth integration of the 48-volt system means less strain on the combustion engine, translating directly to improved efficiency when waiting at lights or crawling through congested areas. On the open road, the 24 MPG highway figure is equally commendable. The Range Rover’s aerodynamic silhouette, coupled with its advanced automatic (S8) transmission, allows the engine to operate efficiently at cruising speeds. The eight-speed gearbox keeps the engine within its optimal powerband, minimizing unnecessary revs and maximizing momentum. For those long interstate journeys, often undertaken in comfort, this efficiency becomes beneficial.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,750 for the 2025 Range Rover P400 MHEV. This figure is based on 15,000 miles driven per year, split 55% city and 45% highway, using national average fuel prices. For a Range Rover owner, $2,750 per year represents a reasonable operating expense given the vehicle’s stature and performance. It’s part of the ownership experience for a premium, full-size SUV that offers luxury and go-anywhere capability. While not insignificant, it’s a cost absorbed as part of enjoying a vehicle that redefines automotive indulgence and engineering prowess for its segment.

Real-world expectations

In real-world driving scenarios, owners of the 2025 Range Rover P400 MHEV can expect to closely match the EPA ratings, provided they adopt a sensible driving style. The specific MHEV system is not a gimmick; its contribution is palpable, especially in varied driving conditions. Stop-start functionality is smooth and unobtrusive, and the electric boost provides noticeable support during acceleration, reducing the workload on the gasoline engine. Drivers who frequently use the vehicle’s various terrain modes or use its substantial towing capabilities will, naturally, see slightly lower figures. However, for typical daily driving, including commutes and weekend excursions, the P400 MHEV consistently delivers its promise of refined power with intelligent efficiency. The Range Rover is designed for those who demand ultimate luxury and versatility; its fuel economy, while constantly improving, remains secondary to its core mission.

How it compares

Compared to its direct competitors, the 2025 Range Rover P400 MHEV holds its own remarkably well, often surpassing some while falling slightly behind others, depending on the specific powertrain. Consider the Mercedes-Benz GLS 450 4MATIC, which achieves an EPA estimated 21 MPG combined (19 City / 24 Highway) from its own 3.0L inline-six turbo engine with mild-hybrid assistance, virtually identical numbers. The BMW X7 xDrive40i, also with a 3.0L inline-six and mild-hybrid tech, matches the Range Rover with 21 MPG combined (20 City / 24 Highway). For a truly comparable luxury experience, other manufacturers often rely on larger V8 engines that significantly impact fuel economy, such as the Lexus LX 600 which manages a mere 19 MPG combined (17 City / 22 Highway) from its twin-turbo V6. This highlights Land Rover’s success in extracting respectable efficiency from its six-cylinder powertrain without compromising the effortless power delivery expected from a Rover. Delving deeper, you can find all Land fuel economy data. The Range Rover buyer, in this segment, seeks a balance of refinement, capability, and performance, and the P400 MHEV delivers that balance alongside competitive fuel efficiency figures.

Tips to maximize efficiency

Optimizing fuel economy in your Range Rover P400 MHEV involves mindful driving and using its integrated technologies. Employing a smooth and progressive acceleration technique, avoiding abrupt inputs to the throttle, allows the mild-hybrid system to operate more effectively, minimizing fuel consumption during initial take-off and reducing strain on the gasoline engine.

Regularly check your tire pressure and maintain it at the manufacturer’s recommended levels. Under-inflated tires increase rolling resistance, forcing the engine to work harder and directly impacting your MPG both in city and highway driving conditions.

Engage the appropriate driving modes for your conditions. While the Range Rover excels off-road, using the dynamic or comfort modes for everyday tarmac driving will optimize powertrain and suspension settings for efficiency and a relaxed journey.

Make use of the adaptive cruise control on highways, where available. This system can maintain a consistent speed and distance from the vehicle ahead, promoting smoother driving and preventing unnecessary acceleration and braking, which are major fuel consumers.

Minimize unnecessary weight in the vehicle. While the Range Rover is designed to carry substantial loads, removing heavy items that aren’t regularly needed and keeping the exterior free of roof racks or cargo boxes when not in use can significantly reduce aerodynamic drag and improve overall efficiency.
