22 MPG combined is what you can expect when buying the 2025 BMW X7 xDrive40i. Complaining about this figure misses the point. This isn’t about maximizing gas mileage; it’s about effortlessly transporting seven adults in comfort while retaining some sporting character. The X7 buyer isn’t cross-shopping with a Prius. They’re prioritizing space, prestige, and performance, and the xDrive40i’s inline-six delivers on all three, even if it means more frequent stops at the pump.

City and highway performance

Around town, the xDrive40i manages 20 MPG. Stop-and-go traffic inevitably hurts fuel economy, and the X7’s weight makes it worse. However, the smooth power delivery and responsive eight-speed automatic transmission make urban driving a surprisingly pleasant experience. On the open road, expect 24 MPG. This is where the turbocharged inline-six shines, cruising comfortably at highway speeds with ample power in reserve for overtaking. While this figure isn’t class-leading, it’s a respectable showing for a vehicle of this size and capability.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2025 BMW X7 xDrive40i at $2,650. This calculation assumes 15,000 miles of driving per year, using national average fuel prices. Of course, your actual fuel costs will vary depending on your driving habits, the type of driving you do (city versus highway), and local fuel prices. Someone living in a city with particularly high gas prices would likely spend considerably more. However, the $2,650 provides a standardized benchmark for comparison.

Real-world expectations

While the EPA estimates offer a useful baseline, real-world MPG often differs. Aggressive driving, frequent short trips, and carrying heavy loads will decrease fuel economy. Conversely, gentle acceleration, consistent highway driving, and proper tire inflation can improve it. Expect to see figures close to the EPA estimates under normal driving conditions. Visit X7 MPG across all years to see how previous model years have fared, though bear in mind that this is a new model year and drivetrain.

How it compares

The X7’s fuel economy lands it in a competitive set. The Mercedes-Benz GLS 450, another large luxury SUV, achieves a similar 20 MPG city and 24 MPG highway. The Land Rover Range Rover, while offering even greater off-road capability, typically returns lower fuel economy, with some configurations struggling to break 20 MPG combined. Stepping outside the German competition, the Cadillac Escalade, despite its larger V8 engine, sometimes surprises with highway MPG figures in the same ballpark as the X7, though its city MPG typically lags. For more data, explore all Bmw fuel economy data. The key consideration is what the buyer values: if maximizing MPG is important, smaller or hybrid SUVs are far better options. But for those needing the X7’s space and presence, the fuel economy is an acceptable trade-off.

Tips to maximize efficiency

Optimize your driving style. The X7’s turbocharged engine responds well to smooth acceleration and anticipation. Avoid harsh braking and sudden bursts of speed, as these actions consume more fuel than necessary. Use cruise control on the highway to maintain a consistent speed and minimize unnecessary throttle adjustments.

Maintain proper tire inflation. Under-inflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly and inflate them to the recommended level, found on the sticker inside the driver’s side doorjamb. Even a small difference in tire pressure can impact your miles per gallon.

Reduce unnecessary weight. Carrying heavy loads in the X7 will obviously decrease fuel economy. Remove any unnecessary items from the vehicle to lighten the load. This includes removing cargo from the trunk and avoiding carrying extra passengers if possible. Every pound adds up, affecting the engine’s workload.

Service the vehicle according to the manufacturer’s recommendations. Regular maintenance, such as oil changes and air filter replacements, ensures that the engine is running efficiently. A well-maintained engine will deliver better fuel economy than a neglected one. The X7 benefits from diligent upkeep.

Use “Eco Pro” mode. The X7 offers selectable driving modes that prioritize either performance or efficiency. Engage “Eco Pro” mode when you don’t need maximum acceleration. This mode adjusts engine settings and transmission shift points to optimize fuel consumption. It encourages a more relaxed driving style, resulting in noticeable gains.
