25 MPG combined isn’t great, but for the 2018 BMW 440i Gran Coupe, it’s a reasonable compromise. This isn’t an economy car, it’s a stylish, German-engineered sport sedan with a potent 3.0L inline-six engine. The target buyer wants driving enjoyment and distinctive design over outright efficiency. Someone drawn to the 440i Gran Coupe wants the practicality of four doors and a hatchback without sacrificing the spirited performance and premium feel associated with the BMW brand.

City and highway performance

The EPA estimates for the 2018 BMW 440i Gran Coupe detail the expected MPG. City driving is rated at 21 MPG, a predictable figure given the stop-and-go conditions and the engine’s acceleration. On the open highway, the 440i gets 32 MPG. This reflects the engine’s ability to cruise efficiently at higher speeds, aided by the smooth-shifting eight-speed automatic transmission (S8). Drivers who frequently take longer journeys will find the highway MPG a welcome relief, mitigating some of the fuel costs associated with urban driving. The powertrain is optimized for both scenarios and benefits from an intelligent driver.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 BMW 440i Gran Coupe is $2,300. This is based on driving 15,000 miles per year and using national average fuel prices. Actual fuel costs will vary depending on driving habits, local fuel prices, and the mix of city and highway driving. However, the $2,300 figure provides a useful benchmark for comparing the 440i’s fuel consumption to other vehicles in its class. This is a fairly accurate measurement, but can certainly be altered based on how much you drive and how heavy your foot is on the accelerator pedal.

Real-world expectations

While the EPA estimates provide a benchmark, real-world fuel economy can vary. Aggressive driving, frequent short trips, and neglecting vehicle maintenance can all negatively impact MPG. Employing eco-driving techniques and ensuring proper tire inflation can help drivers achieve or even exceed the EPA estimates. Owners often report that the highway figure is achievable, especially on long journeys. Pushing the car frequently may drop the MPG significantly. Ultimately, the actual fuel consumption will depend on how the vehicle is driven and maintained.

How it compares

The 2018 BMW 440i Gran Coupe’s fuel economy is typical for its class. A comparable Audi S5 Sportback, with its turbocharged V6 and standard all-wheel drive, achieves around 24 MPG combined. The Mercedes-AMG C43 Coupe, another performance-oriented competitor, also lands in the mid-20s. These comparisons show the 440i isn’t exceptionally efficient, but it’s also not an outlier. For buyers considering this type of vehicle, the slight MPG differences are often outweighed by styling, performance, and brand preference. You can compare 440I MPG across all years to see trends in the model.

Tips to maximize efficiency

Take advantage of the BMW’s driving modes. Selecting “Eco Pro” mode will remap the throttle response and transmission settings to prioritize fuel efficiency. It might slightly dampen the car’s sporty character, but it can noticeably improve MPG.

Monitor your tire pressure regularly. Underinflated tires increase rolling resistance, which directly impacts fuel economy. Maintaining the recommended tire pressure ensures optimal MPG and extends the life of your tires. It also affects handling, which can be especially impactful during the winter months.

Avoid unnecessary idling. Letting the engine idle consumes fuel without moving the vehicle. If you anticipate being stationary for more than a minute, turn off the engine. Modern engines are designed to restart quickly and efficiently.

Use cruise control wisely. On flat highways, cruise control can help maintain a constant speed and improve fuel efficiency. Avoid using cruise control in hilly terrain, as the system may downshift aggressively to maintain speed, negating any potential fuel savings.

Pay attention to the car’s maintenance schedule. Regular oil changes, air filter replacements, and spark plug maintenance all contribute to engine performance and fuel efficiency. Consider exploring all Bmw fuel economy data for other ideas.
