15 MPG combined is the stark reality for anyone considering a 2021 BMW X5 M Competition. This isn’t a fuel sipper, nor is it trying to be one. We’re talking about a high-performance SUV with a twin-turbocharged 4.4L V8 spitting out over 600 horsepower. The X5 M Competition isn’t for sensible commuting; it exists to deliver blistering acceleration and track-ready handling in a package that can also haul the kids and groceries.

City and highway performance

The EPA estimates the X5 M Competition achieves 13 MPG in city driving and 18 MPG on the highway. The city figure reflects the stop-and-go driving conditions and demands placed on the engine when repeatedly accelerating from a standstill; these conditions make the engine’s thirst readily apparent. The highway number, while still not great, demonstrates how efficiently the engine can run under consistent, lower-load conditions. Remember that the temptation to exploit the M Competition’s power on the open road will inevitably push those figures down. These figures are also significantly impacted by driving style. A heavy foot will punish you at the pump far quicker than gently coaxing the X5 M Competition between freeway exits. You can find X5 MPG across all years to see fuel economy data from past model years.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 BMW X5 M Competition at $3,850. This calculation is based on driving 15,000 miles per year, with 45% of those miles being driven in the city and 55% on the highway. The EPA also uses the national average fuel price at the time of calculation, which is subject to change. This figure serves as an indicator of the financial commitment involved in owning this vehicle, especially when compared to more fuel-efficient alternatives. For someone considering the X5 M Competition, this cost is likely factored into the overall ownership equation and deemed acceptable given the vehicle’s performance capabilities.

Real-world expectations

Achieving the EPA’s numbers in the real world will require effort. The X5 M Competition encourages aggressive driving even with so-called “normal” driving modes. Combine that with the vehicle’s considerable weight and standard all-wheel-drive system, and consistent fuel-efficient driving becomes even more challenging. Expect those city MPG figures to dip lower during rush hour, and don’t be surprised if spirited driving on back roads brings the combined MPG average down closer to 12 or even 10 MPG. The reality is, if you’re buying an X5 M Competition, you’re probably not hypermiling.

How it compares

The X5 M Competition exists in a segment where performance often takes precedence over fuel efficiency but awareness is still valuable. The Mercedes-AMG GLE 63 S Coupe, a direct competitor, delivers similar performance but offers comparable fuel economy around 15 MPG combined. The Porsche Cayenne Turbo S E-Hybrid might offer slightly better fuel economy, especially around town, due to its hybrid powertrain, but that comes at a significant price premium. The Range Rover Sport SVR also delivers similar performance with comparable fuel consumption. The Audi RS Q8, another close competitor, also delivers around 15 MPG combined. For drivers prioritizing fuel economy alongside a BMW SUV, all Bmw fuel economy data is readily available. The buyers in this class understand that performance comes at a price, both in terms of initial investment and ongoing running costs.

Tips to maximize efficiency

While maximizing fuel economy might not be the primary concern for X5 M Competition owners, small adjustments can make a difference. Begin by selecting the “Efficiency” driving mode, if equipped. This typically dampens throttle response and encourages earlier upshifts from the eight-speed automatic transmission, helping to avoid excessive fuel consumption during acceleration.

Maintain a steady speed on the highway whenever possible. The X5 M Competition’s powerful engine is most efficient when cruising at a constant velocity. Using cruise control can help prevent unintentional speed fluctuations that lead to unnecessary fuel burn. Avoid frequent and hard acceleration whenever possible to maximize fuel efficiency.

Ensure tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check the tire pressure regularly and inflate them to the recommended specifications, as indicated on the door jamb or in the owner’s manual.

Be mindful of cargo weight. Carrying unnecessary weight in the vehicle also takes a toll on fuel economy. Remove any items that aren’t essential for your journey to reduce the load on the engine and improve overall efficiency.
