14 MPG combined isn’t going to win any awards for lower fuel costs, but for the 2025 BMW XM Label, it’s almost beside the point. This is a statement vehicle, a high-performance SUV that prioritizes outrageous power, aggressive styling, and a certain “look at me” presence over frugality. The XM Label buyer isn’t cross-shopping Priuses; they’re seeking exclusivity and aren’t overly concerned with the cost of filling the tank.

City and highway performance

The EPA estimates the XM Label achieves 12 MPG in the city and 17 MPG on the highway. The city figure reflects the demands of stop-and-go traffic, where the hefty curb weight and instant torque of the 4.4L twin-turbo V8 will be continuously working. The highway number, while slightly better, still acknowledges the vehicle’s aerodynamic inefficiencies and the engine’s need to maintain high speeds effortlessly. Aggressive driving, which the XM Label encourages at every press of the accelerator, will likely result in figures lower than the EPA estimates. This is a performance SUV; driving it like one extracts a penalty at the pump.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2025 BMW XM Label to be $4,150. This calculation is based on driving 15,000 miles per year, with roughly 55% of those miles driven in the city and 45% on the highway, using national average fuel prices. Keep in mind that premium fuel is recommended for optimal performance in the XM Label, so this cost will likely be higher than for a vehicle using regular gasoline. For someone willing to spend well over six figures on the vehicle itself, it’s unlikely to be a major deterrent. This level of fuel expenditure is simply the cost of entry for owning a vehicle in this rarefied performance segment; see all BMW fuel economy data to see how the brand compares.

Real-world expectations

While the EPA provides a standardized benchmark, real-world fuel economy can vary significantly depending on driving style, traffic conditions, and environmental factors. Owners who frequently use the XM Label’s full performance potential, engaging “M Mode” for spirited driving sessions, can expect to see fuel economy figures closer to the city rating, regardless of the actual driving environment. Conversely, those who predominantly use the vehicle for longer highway trips, with minimal hard acceleration, might achieve numbers slightly closer to the EPA highway estimate. However, given the sheer weight and performance of the XM Label, exceeding the official numbers will be a challenge.

How it compares

The BMW XM Label exists in a niche segment of ultra-high-performance SUVs, and its fuel economy reflects that reality. The Lamborghini Urus, for example, achieves a similar 14 MPG combined. The Aston Martin DBX707, another competitor, delivers a near-identical 15 MPG combined. Even the Porsche Cayenne Turbo S E-Hybrid, with its plug-in hybrid system, only manages 18 MPG combined when factoring in both electric and gasoline usage. While some may compare it to the base Cayenne, which achieves a significantly better 21 MPG, that comparison misses the point entirely. The XM Label buyer isn’t prioritizing efficiency; they’re prioritizing head-turning performance and presence, attributes where the XM Label excels. The trade-off is a lower MPG figure than more mainstream SUVs.

Tips to maximize efficiency

While the XM Label is not designed for optimal fuel efficiency, there are still ways to slightly improve your gas mileage. Avoid aggressive acceleration and braking, as the powerful engine and heavy curb weight burn extra fuel during these maneuvers. Instead, focus on smooth and gradual inputs, allowing the powertrain to operate in its most efficient range.

Use the vehicle’s driving modes. Select the “Efficient” mode, which optimizes engine and transmission settings for fuel economy. This mode reduces throttle response and encourages earlier upshifts, minimizing unnecessary fuel consumption.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which reduces fuel efficiency. Check your tire pressure regularly and inflate them to the recommended levels found on the doorjamb sticker.

Minimize idling. The XM Label consumes fuel even when stationary with the engine running. If you anticipate being stopped for an extended period, such as at a long traffic light, consider turning off the engine to conserve fuel.
