21 MPG combined won’t win the 2023 Land Rover New Range Rover P400 MHEV any fuel efficiency awards, but that figure is almost beside the point for the affluent buyer considering this vehicle. This isn’t a vehicle purchased for its fuel consumption. It’s acquired for its presence, its go-anywhere capability, and the luxury it offers its occupants, both on and off the paved road. The mild hybrid system offers efficiency gains, but only to a degree.

City and highway performance

The EPA estimates for the P400 MHEV break down to 18 MPG in the city and 26 MPG on the highway. The disparity between these figures reflects the engine’s behavior in different driving conditions. In urban environments, stop-and-go traffic and frequent acceleration place a greater burden on the engine, negating some of the mild hybrid system’s energy recuperation benefits. Out on the open road, the Range Rover can cruise more efficiently, allowing the engine to operate in its sweet spot and the mild hybrid system to contribute more meaningfully to fuel savings. However, it’s still a heavy SUV with a powerful engine fighting against aerodynamic realities at higher speeds.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2023 Land Rover New Range Rover P400 MHEV is estimated at $2,750. This figure is calculated based on driving 15,000 miles per year, with a 55/45 split between city and highway driving, using national average gasoline prices. Fuel prices fluctuate, and individual driving habits can significantly impact this estimate.

Those who spend more time in congested urban areas or have a heavier foot will likely exceed this figure, while those who primarily drive on the highway might see slightly lower costs. The $2,750 is a useful benchmark, but should not be considered gospel. Because the 2023 New Range Rover is new, you can research ROVER MPG across all years to see how technology in this model compares to prior generations.

Real-world expectations

While the EPA provides a standardized yardstick, real-world fuel economy often deviates from the official numbers. Factors like driving style, road conditions, weather, and even tire pressure can all influence fuel consumption. Expect to see variations in your own MPG depending on how and where you drive.

Aggressive acceleration, frequent hard braking, and extended idling will all lead to lower fuel economy. Headwinds, rain, and snow can also increase fuel consumption. Owners should also recognize that larger diameter wheels and tires, often chosen for aesthetic reasons, can also reduce efficiency.

How it compares

Compared to its direct competitors, the 2023 Range Rover P400 MHEV lands in the middle of the pack. The BMW X7 xDrive40i, with its similar inline-six engine, achieves an EPA-estimated 21 MPG combined, mirroring the Range Rover. The Mercedes-Benz GLS 450, another popular choice in this segment, also posts a 21 MPG combined rating. The Cadillac Escalade, with its significantly larger V8 engine, lags behind at 16 MPG combined, reminding us of the fuel consumption penalty associated with traditional large displacement engines.

Buyers considering the Range Rover often cross-shop these other luxury SUVs and will weigh fuel economy against other factors like features, brand prestige, and driving experience. You can also explore all Land fuel economy data on our site.

Tips to maximize efficiency

Take advantage of the Range Rover’s Eco driving mode. This mode adjusts throttle response and transmission shift points to prioritize fuel efficiency. While it might slightly reduce performance, it can contribute to savings, especially during everyday commuting.

Maintain optimal tire pressure. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly and inflate them to the recommended levels, which can be found on the sticker inside the driver’s side door jamb.

Avoid unnecessary idling. Modern engines are designed to be efficient even at startup, so idling for extended periods wastes fuel. If you’re stopped for more than a minute, it’s generally more fuel-efficient to turn off the engine.

Drive smoothly and anticipate traffic flow. Avoid sudden acceleration and hard braking. Maintaining a steady speed and anticipating traffic conditions allows the engine to operate more efficiently and reduces the need for aggressive maneuvers.

Lighten the load. Carrying excessive weight in your vehicle reduces fuel economy. Remove any unnecessary items from the trunk and back seats to minimize the burden on the engine. This is especially crucial when off-roading, as extra gear adds strain and diminishes efficiency.
