The 2023 Land Rover New Range Rover P400 LWB MHEV achieves 21 MPG combined. This vehicle prioritizes luxury, space, and all-terrain capability, so it isn’t usually cross-shopped against a Prius. The P400 is the entry-level engine for the long-wheelbase New Range Rover; a smooth and reasonably powerful engine moving a lot of weight. Buyers typically want the commanding driving position, luxurious interior, and the prestige that comes with the Range Rover badge. Fuel costs are often a low priority.

City and highway performance

The EPA estimates 18 MPG in the city and 26 MPG on the highway for the New Range Rover P400 LWB. The relatively poor city number reflects the vehicle’s weight and frequent stops, where the mild-hybrid system has limited benefit. The highway figure is better, benefiting from the engine’s ability to cruise at lower RPMs and surprisingly good aerodynamics given its upright design. However, achieving these numbers requires a light foot; aggressive acceleration and higher speeds will quickly decrease them. Researching ROVER MPG across all years may prove helpful.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Land Rover New Range Rover P400 LWB MHEV at $2,750. This is based on driving 15,000 miles per year and using national average fuel prices. Individual driving habits, local fuel prices, and the ratio of city to highway driving will affect the actual cost. $2,750 is a substantial annual expense, so consider it a reasonable minimum when budgeting to buy this vehicle.

Real-world expectations

While the EPA estimates provide a benchmark, real-world fuel economy often differs. Expect slightly below the EPA combined rating, especially with frequent city driving and quick acceleration. Terrain influences MPG; hilly or mountainous routes require more engine power, reducing efficiency. Carrying passengers and cargo will likewise decrease fuel economy. Understanding these factors will help owners set expectations and adjust their driving accordingly.

How it compares

The P400 LWB’s fuel economy is in line with its competitors. A BMW X7 M60i, with its 4.4-liter twin-turbo V8, delivers a combined 18 MPG. The Mercedes-Benz GLS 580, another V8-powered competitor, achieves a similar 18 MPG combined. Even six-cylinder options don’t fare much better: the Volvo XC90 T8 Recharge plug-in hybrid posts an EPA combined rating of 27 MPG, but that number drops quickly after the limited electric range is depleted. Reviewing all Land fuel economy data reveals how thirsty the lineup is. For the New Range Rover buyer, these differences are often unimportant because they prioritize other aspects of ownership and accept the associated fuel costs.

Tips to maximize efficiency

Smooth acceleration and braking are critical for maximizing fuel economy in any vehicle, especially a heavy one. Avoid abrupt starts and stops, and anticipate traffic flow to maintain a constant speed as much as possible. Doing so reduces the engine load and fuel consumption.

Proper tire inflation improves fuel efficiency. Check your tire pressures regularly and maintain the recommended levels. Underinflated tires increase rolling resistance, making the engine work harder. See the door jamb sticker for recommended pressures and check them with a reliable gauge.

Minimize idling time, which wastes fuel. Turn off the engine if you anticipate stopping for more than a minute. Modern engines restart quickly, and the fuel saved from avoiding prolonged idling can add up. The P400’s mild hybrid system makes restarting the engine a smooth experience.

Regular maintenance is important for optimal fuel economy. Regular oil changes, air filter replacements, and spark plug maintenance ensure the engine runs efficiently. Follow the manufacturer’s recommended service intervals to keep your vehicle running well.

Use cruise control on the highway, when you can. Maintaining a consistent speed helps optimize fuel consumption because the engine doesn’t work as hard to change speed. Be aware of the terrain and adjust your speed as needed to avoid unnecessary acceleration.
