14 MPG combined. That’s the headline figure for the 2024 BMW XM 4.4L 8-cyl, and it’s frankly irrelevant to the vehicle’s target demographic. This isn’t a car bought by drivers seeking lower fuel costs. It’s a statement piece, a high-performance hybrid SUV that prioritizes power and presence over frugality. The XM buyer wants aggressive styling, blistering acceleration, and the cachet of owning BMW’s most audacious SUV, and they’re willing to pay the price at the pump.

City and highway performance

The EPA estimates for the XM break down to 12 MPG in the city and 17 MPG on the highway. These figures highlight a significant difference between its urban and long-distance fuel consumption. Stop-and-go city driving will inevitably lead to the worst fuel efficiency due to frequent acceleration and braking, situations where the XM’s considerable weight works against it. On the open road, the hybrid system can contribute more effectively, but even then, the XM’s potent engine and hefty curb weight prevent it from achieving truly impressive highway numbers.

Annual fuel cost

According to the EPA, owning and operating a 2024 BMW XM will cost you approximately $4,150 in fuel annually. This calculation is based on driving 15,000 miles per year, with an assumed even split between city and highway driving, and uses the national average fuel price at the time of calculation. Keep in mind that this is an estimate; your actual fuel costs may vary depending on your driving habits, local fuel prices, and the proportion of city versus highway miles you drive. The aggressive driving style the XM encourages will quickly send that figure upward.

Real-world expectations

Don’t expect to consistently match the EPA estimates in real-world driving. The XM’s power is addictive, and its aggressive styling practically begs for enthusiastic acceleration. Drivers with a heavy foot will likely see MPG figures below the official estimates. Factors such as weather conditions, tire pressure, and cargo weight can all influence fuel consumption. If you consistently drive in demanding conditions or prioritize performance above all else, be prepared for even lower MPG numbers. Check XM MPG across all years to get realistic data from owner forums.

How it compares

The XM’s fuel economy sits at the lower end of its competitive set. The Lamborghini Urus, with its naturally aspirated V8, achieves a similar 14 MPG combined, reflecting a “performance at any cost” philosophy. Even hybrid rivals like the Porsche Cayenne Turbo S E-Hybrid, rated at 17 MPG combined when running in hybrid mode (and significantly lower when relying solely on the gasoline engine), offer slightly better fuel economy. The Mercedes-AMG GLE 63 S Coupe, another performance SUV competitor, manages around 15 MPG combined. While the differences seem small on paper, they add up over time and reflect the compromises inherent in prioritizing raw power and assertive styling above all else. Checking all Bmw fuel economy data might reveal some more efficient options within the brand.

Tips to maximize efficiency

Use the hybrid system’s electric-only mode whenever possible, especially during low-speed, stop-and-go driving. This can significantly reduce fuel consumption in urban environments. Get familiar with the various driving modes and select the “Efficiency” setting for relaxed cruising, which optimizes the powertrain for fuel conservation.

Resist the urge to constantly exploit the XM’s immense power. Gentle acceleration and consistent speeds will improve fuel economy. Anticipate traffic flow and avoid unnecessary braking or sudden acceleration.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, consuming more fuel. Check your tire pressure regularly and maintain it at the recommended level stated on the doorjamb placard.

Limit the use of power-hungry accessories like air conditioning and heated seats, especially during short trips. These features place additional load on the engine, reducing fuel efficiency.

Keep the vehicle well-maintained with regular servicing. A properly tuned engine operates more efficiently. Ensure that air filters are clean and that spark plugs are in good condition.
