22 MPG combined is probably not the main reason someone buys a 2019 BMW X7 xDrive40i. This is a full-size, three-row luxury SUV engineered for comfort, performance, and presence, rather than saving fuel. Buyers in this segment prioritize space, towing capacity, and a premium driving experience over outright efficiency, and the X7 delivers on those things, even if it trails some competitors in MPG.

City and highway performance

The X7’s EPA ratings are 20 MPG in the city and 25 MPG on the highway. The city figure reflects the realities of stop-and-go traffic, where the X7’s weight demands more fuel to accelerate from a standstill. On the open road, the 3.0L turbocharged inline-six shows its relaxed cruising ability. 25 MPG highway is achievable, but it requires a light foot and keeping the speed within legal limits. The eight-speed automatic transmission helps optimize fuel economy by keeping the engine in its most efficient range, but aggressive acceleration will quickly negate any gains.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,650 for the 2019 BMW X7 xDrive40i. This calculation is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, using national average fuel prices. While your actual fuel costs will vary based on your driving habits and fuel prices in your area, this figure provides a useful benchmark for comparing the X7 to other vehicles in its class. This is a strong indication that this is not an economy car. For more information, check X7 MPG across all years.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy can vary significantly. Drivers who frequently drive aggressively or spend most of their time in heavy traffic will likely see numbers below the EPA estimates. However, those who primarily drive on the highway and practice efficient driving techniques may achieve figures closer to, or even slightly above, the 25 MPG highway rating. Factors such as tire pressure, weather conditions, and the use of accessories like air conditioning can also impact fuel consumption. The advertised fuel economy is an optimistic estimate.

How it compares

The BMW X7 xDrive40i lands in the middle of the pack when compared to its competitors. The Acura MDX, for example, achieves a combined 22 MPG with its standard front-wheel-drive setup, while the all-wheel-drive version drops slightly. The Volvo XC90 B5 delivers about 24 MPG combined. The Mercedes-Benz GLS 450 is slightly less efficient, managing around 20 MPG combined. For buyers cross-shopping these SUVs, the fuel economy difference might not be the only deciding factor; the overall driving experience, features, and brand prestige often weigh more heavily.

Tips to maximize efficiency

Take it easy on the accelerator. The X7’s turbocharged engine delivers ample power, but aggressive acceleration consumes significantly more fuel. Smooth, deliberate acceleration will help you stay closer to the EPA estimates.

Maintain proper tire pressure. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly and inflate your tires to the recommended pressure listed on the driver’s side door jamb.

Minimize idling. Idling consumes fuel without moving the vehicle. If you anticipate waiting for more than a minute, turn off the engine to save fuel. The X7’s automatic start/stop system, which shuts off the engine at stoplights, also contributes to fuel savings in city driving, provided you don’t find it intrusive.

Use cruise control on the highway. Maintaining a consistent speed on the highway can improve fuel economy. Cruise control helps avoid unnecessary acceleration and deceleration, which can waste fuel.

Lighten the load. Carrying unnecessary weight in the vehicle reduces fuel economy. Remove any items from the cargo area that you don’t need to carry regularly.
