25 MPG combined isn’t going to win any hypermiling competitions, but it’s a perfectly acceptable number for a sporty, all-wheel-drive coupe with a smooth inline-six. The 2017 BMW 440i xDrive Coupe prioritizes performance and driving pleasure. This fuel economy reflects that, and its typical buyer understands the trade-off. This is for the driver who values a responsive throttle, a balanced chassis, and the surefootedness of xDrive, someone for whom efficiency is a consideration, not an obsession.

City and highway performance

The EPA ratings break down to 21 MPG in the city and 31 MPG on the highway. The city figure reflects the stop-and-go nature of urban driving, where the 440i’s turbocharged engine spends more time idling or accelerating from a standstill.

The highway number is more impressive, demonstrating the efficiency of the engine and eight-speed automatic transmission when cruising at a constant speed. The engine’s ample torque means it’s not constantly downshifting to maintain speed, which saves fuel. Highway driving is also where the car’s aerodynamics help maximize efficiency. The 440I MPG across all years, however, will vary slightly, model year to model year.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 BMW 440i xDrive Coupe at $2,300. This is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs may vary depending on your driving habits, the type of fuel you use (premium is recommended), and the fluctuating price of gasoline.

If you primarily drive in the city or have a heavy foot, expect to exceed this estimate. Conversely, if you do a lot of highway driving and practice fuel-efficient techniques, you might come in under $2,300.

Real-world expectations

While the EPA provides a standardized benchmark, real-world fuel economy often differs. Drivers of the 2017 440i xDrive frequently report figures close to the EPA estimates, but they can fluctuate widely.

Aggressive driving, frequent short trips, and cold weather can all negatively impact fuel economy. Conversely, a long road trip with a steady pace can easily yield highway MPG numbers exceeding 31. The 25 MPG combined rating is a reasonable expectation, but your personal results will vary based on individual driving patterns and conditions.

How it compares

Compared to its competitors, the 2017 BMW 440i xDrive Coupe holds its own. The Audi S5 Coupe, with its supercharged V6 and all-wheel drive, achieves around 24 MPG combined. The Mercedes-Benz C43 AMG Coupe, offering even more performance, typically returns numbers in the low 20s. The Lexus RC 350 AWD, while less powerful, offers similar fuel economy to the 440i at around 24 MPG combined. A rear-wheel-drive 2017 Infiniti Q60 with the 3.0t engine also scores in the low-to-mid twenties. For the person considering the 440i, these comparisons matter because they highlight the balance between performance and efficiency within this class of sporty coupes. All Bmw fuel economy data across the model line highlight this performance/efficiency tradeoff, which has defined the brand for decades.

Tips to maximize efficiency

Use the driving modes. The 440i offers Eco Pro, Comfort, Sport, and Sport+ modes, each influencing throttle response, transmission behavior, and steering feel. Eco Pro prioritizes fuel efficiency by softening throttle inputs and optimizing the air conditioning system. Select it during relaxed cruising to squeeze out extra miles per gallon.

Maintain a smooth driving style. Avoid harsh acceleration and braking. Gentle acceleration and coasting whenever possible allow the engine to operate more efficiently. Anticipating traffic flow and maintaining a consistent speed also contributes to better fuel economy.

Ensure proper tire inflation. Underinflated tires increase rolling resistance, which reduces fuel efficiency. Check your tire pressure regularly and inflate them to the recommended levels, typically found on a sticker inside the driver’s side doorjamb or in the owner’s manual. Even a few PSI below the recommended pressure can noticeably impact fuel consumption.

Reduce unnecessary weight. Carrying extra weight in the car strains the engine and reduces fuel economy. Remove any unnecessary items from the trunk and back seats. The less the car weighs, the less energy it takes to accelerate and maintain speed.

Consider using cruise control on the highway. Cruise control helps maintain a constant speed, which can improve fuel efficiency on long drives. However, avoid using cruise control in hilly areas, as the system may downshift frequently to maintain speed, negating any potential fuel savings.
