25 MPG combined won’t win any awards for low fuel costs, but it’s a perfectly acceptable figure for the 2024 BMW M440i xDrive Gran Coupe. It’s not trying to compete with a Prius; it’s a stylish, performance-oriented four-door coupe designed for buyers who prioritize the driving experience, all-weather confidence, and a touch of luxury over squeezing every last mile from a gallon of premium fuel. This is a car bought with passion, and fuel efficiency is secondary.

City and highway performance

The EPA estimates the M440i xDrive Gran Coupe gets 22 MPG in the city and 30 MPG on the highway. The city figure reflects the stop-and-go nature of urban driving, where the engine works harder and the car’s weight affects fuel consumption. The highway number shows what’s possible when the turbocharged inline-six can stretch its legs, helped by the smooth eight-speed automatic transmission. Owners who frequently drive long distances will likely see numbers closer to the highway estimate. Those who mainly use the car for commuting in congested areas should expect something closer to the city rating.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,300 for the 2024 BMW M440i xDrive Gran Coupe. This is based on driving 15,000 miles per year and assumes current national average fuel prices for premium gasoline, which the M440i requires. Individual fuel costs will vary based on driving habits, local fuel prices, and the amount of city versus highway driving. $2,300 provides a reasonable benchmark for potential owners to consider when budgeting.

Real-world expectations

While EPA ratings offer a standardized comparison, real-world fuel economy can change. Aggressive driving, frequent acceleration, and using launch control will significantly decrease MPG. However, a gentler driving style and using the car’s Eco Pro mode, if equipped, can help achieve numbers closer to the EPA estimates. Many owners report achieving slightly higher than EPA highway MPG on long trips, especially when maintaining consistent speeds. Factors such as tire pressure, vehicle load, and even weather conditions also affect fuel economy.

How it compares

The M440i xDrive Gran Coupe’s fuel economy is similar to other performance-oriented four-door coupes. The Audi S5 Sportback earns an EPA-estimated 24 MPG combined. The Mercedes-AMG C43 Coupe gets slightly lower fuel economy at 22 MPG combined, as its performance is more aggressive. If fuel economy is a higher priority, the base BMW 430i Gran Coupe achieves a significantly better 28 MPG combined, showing the fuel consumption impact of a less powerful engine. Buyers choosing between these vehicles must weigh the M440I MPG across all years or the increased performance against the cost at the pump.

Tips to maximize efficiency

Use the drive mode selector. The M440i’s Comfort and Eco Pro modes are tuned for efficiency, reducing throttle response and optimizing transmission shift points. Use these modes during everyday driving to minimize fuel consumption without sacrificing too much performance. Sport and Sport+ modes can provide more responsive driving, but they will lower your fuel economy.

Check your tire pressure regularly. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure at least once a month and adjust as needed to the recommended pressure listed on the driver’s side doorjamb. Properly inflated tires also improve handling and extend tire life.

Avoid unnecessary idling. Letting the engine idle for extended periods wastes fuel, even in cold weather. If you’re stopped for more than a minute, turn off the engine. Modern engines warm up quickly while driving, so there’s no need to idle them beforehand.

Drive smoothly, avoiding sudden acceleration and hard braking. Anticipate traffic flow and maintain a steady speed whenever possible. Cruise control on the highway helps maintain a consistent speed and improves fuel economy, especially on long drives.

Consider the weight you’re carrying. Extra weight in the vehicle increases the load on the engine which decreases efficiency. Remove any unnecessary items from the trunk and passenger area to reduce the burden. This is a quick and easy way to improve fuel efficiency without changing your driving habits.
