25 MPG combined isn’t going to win any hypermiling awards, but it’s a perfectly acceptable figure for the 2021 BMW M440i xDrive Coupe. It’s not a vehicle bought for its frugality; it’s purchased for its striking looks, engaging driving dynamics, and potent turbocharged inline-six engine. The fuel economy is simply a cost of admission, a compromise accepted by those who prioritize performance and style in a sporty coupe with all-weather confidence.

City and highway performance

The EPA estimates the M440i xDrive Coupe will achieve 22 MPG in the city and 31 MPG on the highway. The relatively modest city figure reflects the engine’s eagerness to rev and the driver’s likely inclination to make use of the available power. Highway economy is more commendable; the engine’s efficiency at cruising speeds and the eight-speed automatic transmission’s ability to select the optimal gear for fuel conservation ensure this. Remember who the target market is: someone who values responsive power and thrilling acceleration over pure fuel savings.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 BMW M440i xDrive Coupe at $2,300. This calculation is based on driving 15,000 miles per year, using national average fuel prices, assuming a certain percentage of city versus highway driving, and using premium grade gasoline. The actual cost will vary depending on individual driving habits, local fuel prices, and the type of driving (more stop-and-go traffic versus open highway). Drivers with a heavier foot or those who spend more time in congested urban areas can expect to exceed this figure, while more conservative drivers might see slightly lower costs.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy often diverges due to driving style, weather, and vehicle maintenance. Owners who frequently engage the M440i’s Sport or Sport+ modes will undoubtedly see lower MPG numbers than someone who primarily drives in Comfort mode. Aggressive acceleration, hard braking, and frequent short trips negatively impact fuel efficiency. Tire pressure and properly functioning sensors all contribute to maximizing fuel efficiency. Expect to see figures within a few MPG relative to the EPA estimates, depending on your driving habits and conditions. Nobody buys this car to drive efficiently; it is about performance.

How it compares

In the realm of sporty coupes, the M440i xDrive’s fuel economy positions it competitively within its segment. The Audi S5 Coupe, with its turbocharged V6, achieves an EPA-estimated 24 MPG combined, slightly less than the M440i. The Mercedes-AMG C43 Coupe is more powerful but sacrifices some efficiency at around 22 MPG combined, making the M440i a slightly better bet for those watching fuel costs. Even within the BMW family, you can compare all BMW fuel economy data to see how the M440i stacks up against other models. Across all model years, the M440I MPG across all years sits in a similar class. These buyers compare the differences carefully, not to maximize their fuel efficiency, but to get the most out of their dollars spent.

Tips to maximize efficiency

Even in a performance-oriented vehicle like the M440i xDrive, there are steps you can take to optimize fuel efficiency. Avoid aggressive acceleration and hard braking whenever possible. Anticipate traffic flow and maintain a steady speed to use less gas. The car’s eight-speed automatic is eager to shift and keep fuel use to a minimum when driven responsibly.

Use the car’s Eco Pro mode in low speed situations, such as stop and go city driving. While it might slightly dampen throttle response, it will help optimize fuel consumption by adjusting the engine and transmission settings to prioritize efficiency. Make frequent use of adaptive cruise control, which can maintain a safe following distance and consistent speed, reducing unnecessary acceleration and braking on the highway.

Ensure your tires are properly inflated to the recommended pressure. Underinflated tires increase rolling resistance, leading to greater fuel consumption. Check tire pressure regularly, especially during temperature changes, as tire pressure fluctuates with ambient temperature. Use premium fuel as recommended by BMW to ensure optimal engine performance and fuel efficiency.

Remove any unnecessary weight from the vehicle. Excess cargo in the trunk or back seat adds to the vehicle’s weight, requiring more energy to accelerate and maintain speed, which will adversely affect mileage. Perform regular maintenance, including air filter replacements and oil changes, to keep the engine running smoothly and efficiently. A well-maintained engine consumes less fuel and emits fewer pollutants.
