19 MPG combined. That is the figure for the 2026 BMW X5 M60i xDrive. For buyers of this machine, it’s not just a number on a sticker; it shows the engineering that can get such efficiency from a luxury performance SUV with a twin-turbo V8 engine. This isn’t a vehicle bought for fuel economy. It’s purchased for its power, its refined cabin, its commanding presence, and its ability to easily handle highway miles while keeping occupants comfortable. The buyer here seeks the ultimate X5, a vehicle that becomes an extension of their lifestyle, and they accept that 523 horsepower and nearly 550 lb-ft of torque inherently comes with a certain thirst.

City and Highway Performance

Breaking down the 19 MPG combined figure, we see 17 MPG in the city and 22 MPG on the highway. The city figure, 17 MPG, is what one would expect from a vehicle of this caliber and weight, driven at lower speeds with frequent stops and starts. The 4.4L twin-turbo V8, while powerful, also has a 48V mild-hybrid system. This system contributes to smooth start-stop operation and offers a subtle power boost, which, while primarily designed for performance, does offer some marginal efficiency benefit in stop-and-go urban situations. However, the X5 M60i is designed to move with authority, not sip fuel politely in congested traffic. The highway figure of 22 MPG is arguably more impressive for this powertrain. Once at cruising speed, the X5’s smooth 8-speed automatic transmission, aerodynamic profile, and optimized engine management allow the S68 V8 to settle into its stride. The extended highway runs, where the engine operates in its most efficient band, are where the 48V system’s ability to assist and recuperate energy is most effective, leading to a respectable showing for a vehicle capable of sprinting to 60 mph in a scant 4.1 seconds.

Annual fuel cost

The EPA estimates an annual fuel cost of $3,050 for the 2026 BMW X5 M60i xDrive. This figure is based on a calculation of driving approximately 15,000 miles per year, with a split of 45% highway and 55% city driving, using national average fuel prices for premium gasoline. For the buyer considering an X5 M60i, this $3,050 annual expenditure is a known factor, a line item in their luxury vehicle budget. They understand that a performance-oriented, premium fuel-guzzling SUV will have higher running costs than a more economical sedan or a hybrid. This isn’t a cost that deters them, but rather an accepted attribute of owning a vehicle that delivers performance and luxury. It represents a small fraction of the overall cost of ownership, overshadowed by depreciation, insurance, and the initial substantial purchase price.

Real-world expectations

In the real world, achieving the EPA ratings for the X5 M60i will largely depend on driving habits. Those who frequently exploit the full potential of its 523 horsepower, which is a significant part of the M60i’s appeal, will inevitably see figures lower than 19 MPG combined. Aggressive acceleration, sustained high speeds, and frequent use of sport modes will all contribute to increased fuel consumption. Conversely, drivers who maintain a light foot, use cruise control on highways, and operate predominantly in Comfort or Eco Pro modes might find themselves consistently hitting or even slightly exceeding the EPA estimates. This is a powertrain that rewards restraint with efficiency, but it constantly tempts with its prodigious power. Ultimately, the X5 M60i is a driver’s SUV, and its real-world fuel economy is a direct reflection of how emphatically that driver chooses to engage with its dynamic capabilities. Expect an average in the high teens if you’re enjoying the power, and possibly scratching at 20-21 MPG on relaxed highway trips.

How it compares

When placed alongside its direct competitors, the X5 M60i holds its own, often besting rivals or matching them in efficiency despite its considerable power output. Consider the Mercedes-AMG GLE 53 Coupe, which, with its milder turbocharged inline-six, manages 20 MPG combined (18 city/23 highway). The X5 M60i, with two more cylinders and significantly more power, is only down by a single MPG. The Porsche Cayenne S, another direct competitor and perennial benchmark, offers 20 MPG combined (17 city/23 highway) from its twin-turbo V8, virtually identical to the BMW. Even more potent options, like the Audi SQ8 with its 20 MPG combined (18 city/24 highway), show that BMW is highly competitive. For those looking at a slightly different flavor, an entry like the Land Rover Range Rover Sport P550e with its plug-in hybrid drivetrain offers an impressive 53 MPGe combined, but that comes with the added complexity of a plug-in system and a different power delivery profile. The X5 M60i’s efficient use of its substantial V8 power against this backdrop shows BMW’s engineering, offering a blend of performance and reasonable consumption within its peer group. You can explore all BMW fuel economy data, and specifically X5 MPG across all years, to see how the model line has evolved.

Tips to maximize efficiency

While the X5 M60i is undeniably thirsty, a few mindful habits can help nudge those MPG figures upward. Employing the Eco Pro driving mode whenever possible is the most straightforward approach, it recalibrates throttle response, transmission shift points, and climate control to prioritize efficiency without totally neutering the driving experience.

Anticipating traffic flow and avoiding aggressive braking and acceleration cycles will significantly impact city fuel economy. Smooth inputs are always more efficient than abrupt ones, even when piloting a luxurious performance SUV like this.

Maintaining proper tire pressure is a simple yet often overlooked factor in fuel efficiency. Under-inflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel, so check them regularly.

On highway journeys, using the X5 M60i’s advanced cruise control system, particularly adaptive cruise control, can help maintain a consistent speed and optimal following distance, both of which contribute to better long-distance fuel economy.

Finally, minimizing unnecessary weight in the vehicle and opting for roof rack delete if you don’t need it can also contribute to marginal fuel savings. Every little bit helps when you’re dealing with a powerful, premium machine like the X5 M60i.
