15 MPG combined. Let’s be clear: Nobody buying a 2025 BMW X5 M Competition is prioritizing fuel efficiency. This is a sledgehammer of an SUV, a vehicle engineered to deliver brutal acceleration and surprisingly agile handling for its size. Fuel consumption is a side effect, a tax you pay for the privilege of unleashing 617 horsepower on demand.

City and highway performance

The EPA estimates for the X5 M Competition are 13 MPG in the city and 18 MPG on the highway. These figures reflect the inherent inefficiency of a high-performance, twin-turbocharged V8 engine powering a roughly 5,400-pound SUV. Stop-and-go city driving will undoubtedly see you hovering around, or even dipping below, the 13 MPG mark. Highway cruising, if you can resist the urge to exploit the engine’s potent passing power, might allow you to approach the 18 MPG estimate. But a sustained high-speed run will quickly erase any gains.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2025 BMW X5 M Competition at $3,850. This figure is based on driving 15,000 miles per year and using national average fuel prices. Keep in mind that this is just an estimate. Actual fuel costs will vary depending on your driving habits, your local fuel prices, and the type of fuel you use. Given the X5 M Competition’s high-performance engine, premium fuel is strongly recommended, which will further increase your expenses.

Real-world expectations

Forget the EPA estimates. Real-world MPG in the X5 M Competition is going to be lower, especially if you drive it the way it’s intended to be driven. Expect to see average fuel economy in the low teens, perhaps even single digits, during spirited driving. Owners who spend most of their time in urban environments, and who frequently exploit the vehicle’s performance, will likely find themselves visiting the gas station often. The X5 M Competition isn’t a daily commuter; it’s a special-occasion vehicle that trades efficiency for raw power and driving thrills. Consider looking at X5 MPG across all years if you want a different model.

How it compares

The BMW X5 M Competition exists in a rarefied segment of high-performance SUVs. The Mercedes-AMG GLE 63 S Coupe, with its own twin-turbo V8, delivers similar performance and gets around 15 MPG combined. The Porsche Cayenne Turbo offers comparable power and handling, managing around 17 MPG combined. The Land Rover Range Rover Sport P530 also achieves approximately 17 MPG combined. These marginal differences in MPG are unlikely to sway a buyer already committed to this level of performance; the choice will largely depend on brand preference, styling, and specific features.

Tips to maximize efficiency

While squeezing every last drop of fuel from the X5 M Competition might seem counterintuitive, some strategies can help to optimize efficiency without completely sacrificing performance. Avoid hard acceleration and braking whenever possible. Smooth, gradual inputs will reduce fuel consumption compared to aggressive driving.

Make use of the X5 M Competition’s driving modes. Selecting “Comfort” or “Eco Pro” will dial back the engine’s responsiveness and adjust the transmission’s shift points to prioritize fuel economy. Even in these modes, this vehicle will still consume a fair amount of fuel just from its size and weight.

Ensure that your tires are properly inflated. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly and maintain the recommended pressure specified on the doorjamb sticker.

Reduce unnecessary weight. Carrying extra cargo in the vehicle adds weight, which requires more energy to move. Remove any items you don’t need to improve fuel efficiency. All all Bmw fuel economy data may be affected by weight.

Plan your trips strategically. Combine errands and take routes that minimize stop-and-go traffic. Avoiding rush hour and congested areas can significantly improve your overall fuel economy.
