22 MPG combined is what you can expect with the 2023 Land Rover Discovery MHEV 3.0L 6-cyl. While that number might seem underwhelming, it’s typical for a vehicle that focuses on off-road ability, interior space, and a certain British style. This isn’t a vehicle for hypermilers. It’s for families who want a high driving position, the ability to handle tough terrain, and the comfortable features associated with the Land Rover brand. Buyers often live where all-wheel drive is a necessity, or they enjoy outdoor adventures where the Discovery’s capabilities are useful.

City and highway performance

The EPA estimates the 2023 Land Rover Discovery MHEV will get 19 MPG in the city and 25 MPG on the highway. The city figure reflects the demands on the 3.0L inline-six engine and its mild-hybrid system in stop-and-go traffic. The mild-hybrid assistance is meant to improve responsiveness and fuel efficiency, but the Discovery’s weight and the nature of urban driving reduce its effectiveness. While 25 MPG on the highway is possible, it depends on maintaining consistent speeds and avoiding quick acceleration. Using cruise control and predicting traffic flow can significantly improve highway MPG.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Land Rover Discovery MHEV at $2,650. This is based on driving 15,000 miles per year and using national average fuel prices. Individual fuel costs will vary based on driving habits, local fuel prices, and the gasoline grade used. $2,650 per year is a significant expense. However Discovery buyers usually consider this in the overall cost, understanding that capability and luxury cost more. Always compare ROVER MPG across all years to see how the model’s fuel economy has changed.

Real-world expectations

EPA estimates provide a starting point, but actual fuel economy often differs. Drivers who frequently engage the all-wheel-drive system, tow trailers, or drive fast will likely see lower MPG than advertised. On the other hand, those who prioritize fuel-efficient driving may match or slightly exceed the EPA estimates. Tire pressure, outside temperature, and the use of accessories like air conditioning can also affect fuel consumption. Most Discovery owners should expect combined MPG figures in the low-20s.

How it compares

The Land Rover Discovery MHEV is in a competitive class with other luxury SUVs with similar capabilities. The Volvo XC90 B6, for example, gets a combined 22 MPG, like the Discovery, but offers a different driving experience and interior style. The BMW X5 xDrive40i gets a slightly better 23 MPG combined. A Mercedes-Benz GLE 450 gets around 22 MPG combined as well. Looking at all Land Rover fuel economy data shows the Discovery’s place in the brand’s lineup. These comparisons are important for buyers who prioritize efficiency, but often the Land Rover’s unique combination of off-road capability, brand recognition, and unique design outweigh small differences in fuel economy. The Discovery’s strong build and wading depth are necessities for some, making competitors with less capable off-road systems automatically unsuitable.

Tips to maximize efficiency

The Land Rover Discovery’s mild-hybrid system is designed to improve fuel efficiency, but it works best with smooth acceleration and deceleration. Avoid fast starts and hard braking, allowing the system to regenerate energy when slowing down. This helps recharge the battery and reduces the load on the engine.

Maintaining correct tire pressure is critical for good fuel economy. Underinflated tires increase rolling resistance, making the engine work harder and consume more fuel. Check your tire pressure regularly and inflate them to the recommended levels on the doorjamb sticker.

Reduce unnecessary weight inside the vehicle. Carrying extra cargo affects fuel efficiency. Remove any items that aren’t needed for your trip. Even small weight reductions can add up and make a difference.

When possible, use cruise control on the highway to maintain a consistent speed and avoid changes in throttle. This can help you achieve the best possible highway MPG. Watch out for inclines and declines, and adjust your speed to avoid unnecessary acceleration or slowing down.

Plan your route carefully, because avoiding stop-and-go traffic and shorter trips is helpful. During cold temperatures, be sure to precondition the cabin while the vehicle is plugged in so that the engine does not require as much load and burn as much energy to heat the cabin.
