22 MPG combined is an acceptable figure for the 2020 BMW X5 xDrive40i. It’s certainly not class-leading, nor is it intended to be. This is a mid-size luxury SUV with a potent inline-six engine and standard all-wheel drive, typically bought by drivers who prioritize performance and a premium driving experience over saving gas. Fuel costs are a consideration, of course, but they’re lower on the list than factors like handling, technology, and brand cachet.

City and highway performance

The EPA estimates for the 2020 X5 xDrive40i break down to 20 MPG in the city and 26 MPG on the highway. The city number reflects the stop-and-go nature of urban driving, where the X5’s weight and all-wheel-drive system demand more from the engine. The highway figure is more respectable, partially thanks to the smooth-shifting eight-speed automatic transmission’s ability to cruise at lower RPMs. Remember, though, that the X5 xDrive40i is not a hybrid, and attempts to drive it like one will result in disappointment at the gas pump.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2020 BMW X5 xDrive40i to be $2,650. This number is derived from the EPA’s combined MPG rating (22 MPG), an estimated 15,000 miles driven per year, and the national average fuel price. This is an estimate. Your actual fuel costs will vary depending on your driving habits, the type of fuel you use, and local gas prices. Those who drive aggressively or spend more time in stop-and-go traffic can expect to exceed this figure. You can always view X5 MPG across all years to see if different model years are more efficient.

Real-world expectations

While the EPA estimates provide a useful baseline, real-world fuel economy often differs. Many X5 xDrive40i owners report MPG figures in a range of about 18-24 MPG in mixed driving. This variance depends heavily on individual driving style and typical routes. A lead foot or frequent short trips, especially in colder weather, will significantly reduce fuel economy. Drivers who prioritize smooth acceleration and spend more time on open highways may see numbers closer to, or even slightly above, the EPA’s 26 MPG highway estimate.

How it compares

The 2020 BMW X5 xDrive40i’s fuel economy is in the middle of its competitive set. The Acura MDX, with its standard V6 engine and all-wheel drive, typically achieves around 21 MPG combined. The Mercedes-Benz GLE 350 4MATIC, another direct competitor, mirrors the X5’s 22 MPG. The Volvo XC90 T6 AWD, offering a slightly smaller turbocharged and supercharged engine, manages around 22 MPG combined as well. The Lexus RX 350 AWD posts a similar 22 MPG combined. While these numbers are close enough to be insignificant for many buyers, some buyers will find slightly better numbers from the Lexus or Acura. For those who value ultimate efficiency, the X5 xDrive45e plug-in hybrid, when driven primarily on electric power, dramatically reduces fuel consumption, though it comes at a higher initial price.

Tips to maximize efficiency

Adopt a smoother driving style. Avoid sudden acceleration and hard braking, as these actions consume significantly more fuel. Anticipate traffic flow and maintain a steady speed whenever possible. The X5 xDrive40i’s engine is responsive, but it doesn’t need to be constantly pushed to its limits.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly and inflate them to the recommended levels, which can be found on the sticker inside the driver’s side door jamb.

Reduce unnecessary weight. Carrying extra cargo in your X5 xDrive40i adds weight, forcing the engine to work harder and consume more fuel. Remove any items that you don’t need on a regular basis, especially heavy objects.

Use the X5’s driving modes. The X5 xDrive40i offers various driving modes, including an “Eco Pro” mode that optimizes fuel efficiency by adjusting throttle response, transmission shift points, and climate control settings. Select this mode when fuel economy is your primary concern.
