16 MPG combined. That’s the fuel economy for the 2016 BMW X6 M, and it’s a figure most buyers of this high-performance, coupe-inspired SUV accept. This isn’t a vehicle purchased for its fuel efficiency; it’s bought for its strong power, aggressive styling, and relatively impractical utility. Someone choosing the X6 M isn’t cross-shopping a Prius; they’re likely considering other performance SUVs where efficiency isn’t the primary concern.

City and highway performance

The EPA estimates reveal a stark difference between city and highway driving. The X6 M gets 14 MPG in the city, reflecting the fuel demands of stop-and-go traffic and the engine’s immediate power delivery. Getting this heavy machine moving, then stopping, takes its toll. However, on the open road, it improves to 19 MPG, a difference likely due to the engine maintaining a consistent speed and operating within a more efficient range. The 4.4L V8’s thirst is less noticeable when cruising, but it’s still far from economical when compared to smaller, less powerful SUVs.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2016 BMW X6 M is $3,600. This figure is based on driving 15,000 miles per year and using national average fuel prices. This is a significant amount compared to more fuel-efficient vehicles, and it highlights the ongoing cost of owning a high-performance SUV, particularly one that enjoys premium gasoline. For X6 M owners, this expense is built into the overall ownership experience, alongside higher insurance premiums and maintenance costs.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy can vary considerably based on driving style, traffic conditions, and even the specific terrain. Aggressive acceleration, frequent hard braking, and hill climbing will all negatively impact fuel consumption. Conversely, gentle acceleration and consistent highway speeds will bring you closer to the EPA’s figures, but surpassing them will be extremely difficult. Those who enjoy the X6 M’s performance capabilities will likely see numbers closer to the city estimate, while those prioritizing efficiency can perhaps nudge closer to the highway figure.

How it compares

Compared to its competitors, the 2016 BMW X6 M sits at the lower end of the fuel economy spectrum.

For example, a 2016 Porsche Cayenne Turbo, with similar performance figures, achieves roughly the same combined MPG. A Mercedes-AMG GLE63 S Coupe, another direct rival, also lands in the same vicinity. Even within BMW’s own lineup, the X6 xDrive35i, with its less powerful six-cylinder engine, achieves significantly better fuel economy, though sacrifices performance. The X6 M buyer isn’t particularly concerned about the few extra miles per gallon offered by its rivals; they likely value the specific styling and performance dynamics that only the M version provides.

Tips to maximize efficiency

While the X6 M is hardly a fuel-sipping machine, there are steps you can take to minimize consumption. Ensure your tires are properly inflated to the recommended pressure can improve rolling resistance and squeezing out a little extra mileage, especially at highway speeds. Keep in mind the high-performance tires can lose pressure more easily so make this a regular check.

Anticipate traffic flow and avoid hard acceleration and braking. The X6 M’s powerful engine responds readily to throttle inputs, but this responsiveness can easily lead to excessive fuel consumption if driven aggressively. Smooth, gradual acceleration and proactive braking will not only save fuel, but also maintain a smoother, more comfortable ride.

Use the X6 M’s driving modes to your advantage. Selecting the “Comfort” or “Eco Pro” mode will tame the engine’s response and optimize the transmission shift points for better fuel efficiency. While these modes may diminish the raw performance, they are suitable for routine daily driving where maximizing fuel economy is a priority.

Minimize the use of accessories like air conditioning, especially during short trips. The A/C compressor places a significant load on the engine, which can noticeably impact fuel economy, particularly in city driving. When practical, opt for fresh air ventilation instead or roll down the windows, especially when the weather is conducive.
