The 2022 BMW X6 xDrive40i gets 23 MPG combined. Fuel economy usually isn’t the main reason people choose this vehicle. Buyers like the X6’s unique coupe shape, its powerful inline-six engine, and the premium driving experience. But knowing how efficient it is, or isn’t, remains important, especially with fuel prices changing so much.

City and highway performance

The EPA estimates the X6 xDrive40i gets 21 MPG in the city and 25 MPG on the highway. The city number shows how much gas it uses in stop-and-go traffic, where the X6’s weight and the way internal combustion engines work make it less efficient. On the highway, the eight-speed automatic transmission (S8) helps keep the engine running efficiently, which helps it get a slightly better highway MPG rating. These numbers are averages. How you drive, the road conditions, and even your tire pressure can change how much fuel you actually use. For more information, check out X6 MPG across all years.

Annual fuel cost

The EPA says the annual fuel cost for the 2022 BMW X6 xDrive40i is about $2,500. This is figured by driving 15,000 miles per year and using average national fuel prices. Changes in gas prices will affect how much you actually spend. The calculation also uses a mix of city and highway driving. Expect to pay more if you drive mostly in the city, and less if you drive mostly on the highway.

Real-world expectations

EPA estimates are a starting point, but many things affect the MPG you’ll get. Driving fast, braking hard a lot, and idling for a long time will all make your fuel economy worse. The X6’s xDrive all-wheel drive system gives you better grip and stability, but it also adds weight and makes the car more complicated, which can lower MPG compared to a rear-wheel-drive version. Weather, like cold temperatures or strong winds, can also affect MPG.

How it compares

The X6’s fuel economy is about average for a sporty luxury SUV. A Mercedes-Benz GLE 450 Coupe gets around 22 MPG combined, while an Audi Q8 usually gets around 20 MPG. The Porsche Cayenne Coupe, with different engines, can get from 17 MPG to 21 MPG combined, so the X6 seems efficient by comparison. A Land Rover Range Rover Sport with its base engine gets around 19 MPG combined. These differences matter to buyers comparing cars in this class. While saving gas isn’t the biggest concern, knowing you’re not the worst in terms of fuel economy can be a key factor.

Tips to maximize efficiency

Use the X6’s drive mode selector. “Eco Pro” mode changes the throttle, shift points, and climate control to save fuel. You might lose some performance, but it can help on long drives.

Don’t forget to check all Bmw fuel economy data.

Check your tire pressure. Low tires make the engine work harder and use more fuel. Check and keep the tire pressure at the recommended level shown on the sticker on the driver’s side doorjamb. This helps your fuel economy and makes your tires last longer.

Don’t idle too much. Modern engines don’t need to warm up for long. If you’re stopped for more than a minute or two, it’s usually better to turn off the engine and restart it when you’re ready. The X6’s auto start-stop is useful, but can be overriden if needed.

Avoid driving aggressively. Accelerating quickly and braking hard wastes fuel. Accelerate smoothly and watch traffic to improve your fuel economy. The X6 is fun to drive fast, but being gentle saves gas.

On the highway, consider using cruise control. Keeping a steady speed can help you save fuel, especially on long trips. Modern adaptive cruise control systems can make this even better by automatically changing your speed to keep a safe distance from other cars.
