29 MPG combined from a coupe packing a strong 3.0L inline-four and all-wheel drive isn’t going to win any hypermiling contests, but it’s a figure that accurately reflects the M440i xDrive’s mission: performance first, efficiency second. This isn’t a car bought by those prioritizing fuel sippage above all else. This is for the driver seeking a rewarding and engaging experience behind the wheel, one who appreciates the car’s blend of athletic ability and everyday usability. The fuel economy, while not class-leading, is a price they’re willing to pay for the thrill.

City and highway performance

The EPA estimates suggest 26 MPG in the city and 33 MPG on the highway for the 2025 BMW M440i xDrive Coupe. The city figure is respectable given the stop-and-go nature of urban driving, where the engine spends more time idling and accelerating. Out on the open road, the 33 MPG highway number is more attainable, especially with judicious use of cruise control and a relaxed driving style. However, the temptation to exploit the engine’s power and the xDrive system’s grip will inevitably dip the numbers, particularly if your highway driving involves frequent overtaking or keeping pace with fast-moving traffic. The automatic transmission’s eight gears help to keep the engine in its optimal range whether climbing hills or cruising.

Annual fuel cost

According to the EPA, the average annual fuel cost for the 2025 BMW M440i xDrive Coupe is $2,000. 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. Your actual fuel costs will vary depending on your driving style, the type of fuel you use, and local fuel prices. Premium fuel is recommended and will likely impact your real numbers. Still, this $2,000 figure serves as a useful benchmark when comparing the M440i’s running costs to those of its competitors.

Real-world expectations

While the EPA estimates provide a useful framework, real-world fuel economy often deviates. Expect to see figures closer to the EPA’s estimates if you primarily drive on the highway and maintain a conservative driving style. However, if your driving is predominantly in the city or if you frequently indulge in spirited driving, expect your fuel economy to be lower, potentially falling into the low- to mid-20s. The M440i’s eagerness to accelerate and its responsive engine make it difficult to resist the urge to push it, which inevitably impacts fuel consumption. The type of fuel used will also affect the mileage one gets. Refer to all Bmw fuel economy data to compare to other models.

How it compares

The BMW M440i xDrive coupe goes head-to-head with other premium sports coupes, and its fuel economy places it squarely in the middle of the pack. For example, the Audi S5 coupe, with its turbocharged V6 and Quattro all-wheel drive, achieves an EPA-estimated 24 MPG combined. The Mercedes-AMG C43 Coupe, another V6-powered rival with 4MATIC all-wheel drive, also lands around 22 MPG combined. The M440i outperforms both while still delivering comparable performance. A Porsche Cayman, the quintessential sports coupe, sacrifices practicality and all-wheel drive for a sportier driving experience. The base model achieves around 24 MPG combined. Compare this to M440I MPG across all years.

Tips to maximize efficiency

Take advantage of the M440i’s Eco Pro mode, which remaps the throttle response and shift points for optimal fuel efficiency. While it reduces the car’s outright performance, it can significantly improve fuel economy during daily commutes and longer highway drives. and don’t let the engine idle for extended periods, as this burns fuel without covering any distance. Turn off the engine if you anticipate being stationary for more than a minute or two.

Ensure your tires are properly inflated to the recommended pressure, which is usually found on a sticker inside the driver’s side doorjamb or in the owner’s manual. Properly inflated tires reduce rolling resistance and improve fuel economy. Regularly check and adjust tire pressure, especially during seasonal temperature changes.

Avoid aggressive acceleration and hard braking, as these actions consume more fuel than gradual acceleration and smooth braking. Anticipate traffic flow and maintain a steady speed to minimize unnecessary acceleration and deceleration. Practicing smooth driving techniques can make a noticeable difference in fuel consumption.

Reduce aerodynamic drag by removing roof racks or cargo carriers when they’re not in use. These accessories increase wind resistance and negatively impact fuel economy, especially at highway speeds. Also, minimize the use of air conditioning, as it puts additional strain on the engine and reduces fuel efficiency. Use the ventilation system when possible, and only turn on the A/C when it’s absolutely necessary.
