The 2023 BMW M440i Coupe, with its smooth 3.0L inline-six, gets an EPA-estimated 27 MPG combined. Some might find this disappointing for a relatively compact coupe, but they’re missing the point. This car isn’t focused on maximizing every mile per gallon; it prioritizes effortless performance and refined driving enjoyment, a balance many M440i buyers accept.

City and highway performance

The EPA breaks down the M440i’s fuel economy further: 24 MPG in the city and 32 MPG on the highway. The city number reflects stop-and-go driving, where the engine idles more and accelerates from stops. The 32 MPG highway number is more appealing, achieved through the engine’s efficiency, the smooth-shifting eight-speed automatic transmission, and relatively low aerodynamic drag. This allows for comfortable and reasonably economical long-distance cruising, should the M440i owner venture beyond their favorite backroads.

Annual fuel cost

The EPA estimates the 2023 BMW M440i Coupe’s annual fuel cost at $2,150. This is based on driving 15,000 miles per year and using the national average fuel price at the time of calculation. The M440i requires premium fuel, so that annual cost could change based on driving frequency and fuel prices. Some drivers will exceed the 15,000-mile benchmark, increasing their gasoline expenses. Premium fuel is a must for this high-performance six-cylinder, so factor that into your ownership costs.

Real-world expectations

While the EPA figures are a standardized baseline, real-world fuel economy often differs. The M440i’s turbocharged engine is responsive, and frequent use of its power will impact the official MPG numbers. Drivers who prioritize fast acceleration and engaging handling will likely see figures closer to the low 20s in combined driving. But those who adopt a more relaxed driving style and spend more time on the open road might even surpass the EPA’s highway estimate. To see M440I MPG across all years, check out our data.

How it compares

The M440i faces strong competition. The Audi S5 Coupe, another stylish German car, is EPA-rated at 24 MPG combined from its turbocharged V6. The Lexus RC 350, with its naturally aspirated V6, achieves a similar 23 MPG combined. Even the four-cylinder Porsche 718 Cayman manages just 24 MPG combined. These numbers show that performance coupes tend to prioritize driving experience over saving gas. For those looking to compare all Bmw fuel economy data, we offer a guide.

Tips to maximize efficiency

Use a gentler throttle. The M440i’s engine delivers plenty of torque at low RPMs, reducing the need for aggressive acceleration in most situations. Easing off the accelerator pedal can significantly reduce fuel consumption without sacrificing too much performance. The car’s “Comfort” driving mode also adjusts the throttle response and transmission mapping for better efficiency.

Use cruise control. On long highway trips, cruise control helps maintain a constant speed, minimizing unnecessary acceleration and deceleration. This can lead to fuel economy improvements, especially on flat roads. Modern adaptive cruise control systems also maintain a safe following distance, enhancing efficiency and reducing driver fatigue.

Keep tires properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Regularly check and maintain the recommended tire pressure, which can be found on a sticker inside the driver’s side doorjamb or in the owner’s manual. Proper tire inflation also improves handling and safety.

Limit idling time. Excessive idling wastes fuel and pollutes. If you’ll be stationary for more than a minute or two, it’s more efficient to turn off the engine. Modern engines are designed to restart quickly, so there’s no need to let them idle unnecessarily. Especially with premium fuel, idling can be a costly problem.

Reduce aerodynamic drag. While the M440i Coupe is already aerodynamic, adding roof racks or other accessories can increase drag and negatively impact fuel economy. Remove any unnecessary items to minimize wind resistance, particularly on the highway. Regular washing and waxing can also help maintain a smooth surface, further reducing drag.
