22 MPG combined isn’t going to win any awards in 2024, but that’s what buyers of the BMW X7 xDrive40i can expect. This isn’t a car purchased by penny-pinchers; it’s for families who prioritize space, luxury, and a certain driving experience. Fuel economy is a consideration, certainly, but it’s far from the top of the list when cross-shopping a vehicle of this size and caliber.

City and highway performance

The EPA estimates the X7 xDrive40i will achieve 21 MPG in the city and 25 MPG on the highway. These figures reflect the demands placed on the turbocharged 3.0L inline-six and its eight-speed automatic transmission. City driving, with its constant stop-and-go, taxes the engine and negates some of the efficiency gains from the advanced powertrain. The highway figure is more respectable, helped by the transmission’s ability to settle into taller gears and allow the engine to cruise at lower RPMs. The xDrive all-wheel-drive system adds to the vehicle’s weight and complexity, provides sure-footedness that some buyers consider essential, even if it trims overall fuel economy by a small margin.

Annual fuel cost

The EPA calculates an annual fuel cost of $2,650 for the 2024 BMW X7 xDrive40i. This is based on driving 15,000 miles per year and using the national average fuel price at the time of the EPA’s testing. Your individual fuel costs will vary depending on your driving habits, the type of fuel you use, and local fuel prices. Buyers should consider this a baseline figure, understanding that more aggressive driving or higher local fuel costs will increase the amount they spend at the pump. Premium fuel is recommended for optimal performance, which typically commands a higher price.

Real-world expectations

While the EPA estimates provide a useful benchmark, real-world MPG often differs. Drivers who frequently engage in spirited acceleration or live in areas with hilly terrain are likely to see figures below the EPA estimates. Conversely, those who prioritize smooth driving and spend a majority of their time on relatively flat highways might achieve slightly better fuel economy. The X7’s weight and all-wheel-drive system are constant factors, so significant deviations from the EPA numbers are unlikely. The way the vehicle is used, such as frequent short journeys versus longer highway trips, impacts the numbers. To get a clearer picture of their own fuel consumption, many drivers find it useful to track their MPG over time using the vehicle’s trip computer.

How it compares

The X7 xDrive40i’s 22 MPG combined sits roughly in the middle of its competitive set. The Mercedes-Benz GLS 450 4MATIC, for example, is rated at 20 MPG combined, a slight disadvantage in fuel economy for a similar level of luxury and performance. The Volvo XC90 B6 AWD, with its turbocharged and supercharged 2.0-liter engine, achieves a slightly better 23 MPG combined, appealing to buyers who are willing to sacrifice some power for improved efficiency. Even a Cadillac Escalade with the 6.2L V8 nets within a few MPG, which makes the X7 a good bet when considering other similarly-sized SUVs. These comparisons matter to the X7 buyer because they want to ensure they are not drastically overspending on fuel compared to other vehicles they are considering.

Tips to maximize efficiency

Aggressive acceleration significantly impacts fuel economy. The BMW X7 xDrive40i offers ample power, but try to resist the urge to constantly exploit it. Smooth, deliberate acceleration will help the engine operate more efficiently and reduce fuel consumption. Anticipate traffic flow and maintain a steady speed whenever possible.

Regular maintenance is critical for optimal fuel economy. Ensure that your tires are properly inflated, and all fluids are at the recommended levels. A well-maintained engine runs more efficiently, reducing fuel consumption and preventing potential problems down the road. Schedule regular servicing with a qualified BMW technician.

Minimize unnecessary weight in the vehicle. Extra cargo adds to the overall weight, requiring the engine to work harder and burn more fuel. Remove any items that are not essential, especially heavy objects. Doing so, especially when coupled with efficient driving, will maximize fuel efficiency.

Use the X7’s driving modes effectively. Select “Eco Pro” mode when appropriate to optimize fuel efficiency. This mode adjusts throttle response, transmission shift points, and climate control settings to conserve fuel. Do use other settings like “Sport” mode wisely and sparingly because those modes often reduce gas mileage.

Consider the impact of roof racks or cargo carriers. These accessories increase aerodynamic drag, which can significantly reduce fuel economy, particularly at highway speeds. Remove them when not in use to improve airflow and minimize fuel consumption. Anything that negatively impacts the vehicle’s aerodynamic properties will have an inverse impact on its fuel economy.
