17 MPG combined is what you get in the 2020 BMW X7 xDrive50i, a vehicle focused on delivering strong performance and luxury. This number probably won’t deter someone seeking a statement of success in handcrafted leather and powered by a twin-turbocharged V8. This isn’t a vehicle where saving fuel is a priority; it’s a decision based on power, space, and prestige.

City and highway performance

The EPA estimates for the X7 xDrive50i show two sides, though neither is particularly economical. Expect around 15 MPG in city driving. This reflects the stop-and-go driving in cities and the engine’s large size. The X7 does slightly better on the highway, reaching 21 MPG. This is thanks to the eight-speed automatic transmission, which lets the engine run at lower RPMs, and the vehicle’s aerodynamic shape for its size. Remember that these numbers are based on ideal conditions, and aggressive driving will reduce them quickly.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2020 BMW X7 xDrive50i is $3,400. This is based on driving 15,000 miles per year, with a 55/45 split between city and highway driving, using national average fuel prices. This is what the typical driver might spend on gasoline in a year. Your fuel costs may vary, depending on how you drive, where you live, and fuel prices. See the $3,400 figure as a baseline, and be ready to exceed it.

Real-world expectations

The EPA provides a standard estimate, but actual fuel economy often differs. The X7’s weight, along with the driver’s tendency to use the V8’s power, will likely cause numbers that vary from the official figures. Weather, tire pressure, and using accessories like air conditioning can also change fuel consumption. Expect numbers close to the EPA estimates if you drive carefully, but don’t be surprised if you consistently get less, especially when driving fast or on short trips.

How it compares

The 2020 BMW X7 xDrive50i is among other powerful, luxurious, and gas-guzzling SUVs. The Mercedes-Benz GLS 580, for example, gets about 16 MPG combined. An Audi Q7 with the 3.0L V6 gets slightly better mileage at 19 MPG combined but has less power than the X7’s V8. Even the less powerful Range Rover Sport is usually in the same range. For buyers looking at vehicles like the X7, these small MPG differences rarely change their minds. Buyers usually focus on image, performance, and interior quality more than fuel savings. Refer to X7 MPG across all years to see trends across the lineup.

Tips to maximize efficiency

Fuel economy might not be the main thing for X7 xDrive50i owners, but there are ways to improve it. Avoid accelerating quickly and braking hard, since the V8 engine uses much more fuel when pushed hard. Keeping a steady speed and watching traffic can make a difference.

Make sure your tires have the correct pressure. Tires with low pressure increase rolling resistance, making the engine work harder and use more fuel. Check your tire pressure regularly, especially when the seasons change, because temperature changes can affect tire pressure.

Reduce how often you use accessories that put a load on the engine. Air conditioning can significantly reduce fuel economy, especially in city driving. Use it carefully and think about opening windows or using the ventilation system when possible.

Keep your vehicle maintained. Regular oil changes, air filter replacements, and spark plug inspections can help make sure the engine runs well. A well-maintained engine is more efficient. Visit all Bmw fuel economy data for information about other efficient vehicles.
