26 MPG combined isn’t going to win any awards for using less gas, but for the 2025 BMW M240i Coupe and its purpose, most buyers will find it acceptable. This isn’t an economy car; it’s a compact sports coupe with a strong 3.0L turbocharged inline-six. The M240i appeals to drivers who want performance and engagement over fuel efficiency and are willing to trade some MPG for thrilling acceleration and a finely tuned chassis.

City and highway performance

The EPA estimates the M240i Coupe at 23 MPG in the city and 32 MPG on the highway. The city figure shows the engine’s responsiveness and the need to occasionally access that power, but the highway number reveals its cruising abilities. The M240i’s eight-speed automatic transmission helps optimize fuel economy at higher speeds, allowing it to settle into a relaxed and efficient pace on long journeys. These figures aren’t groundbreaking, but they’re respectable considering the power.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2025 BMW M240i Coupe will be $2,250. This calculation is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs will vary depending on your driving habits, location, and the price of gasoline.

Real-world expectations

While the EPA estimates provide a useful baseline, real-world fuel economy can change. Aggressive driving, frequent short trips, and harsh weather conditions can negatively impact MPG. M240i owners who frequently exploit the engine’s performance potential will likely see numbers closer to the city estimate, or even lower. However, those who drive moderately and spend more time on the open road should be able to achieve or even exceed the EPA highway figure. Remember to check M240I MPG across all years to see how previous models performed.

How it compares

The M240i’s fuel economy is interesting within its competitive landscape. A Toyota Supra 3.0, another inline-six-powered sports coupe, manages a slightly better 28 MPG combined. For four-cylinder turbo engines, look at the Mercedes-Benz CLA 250 Coupe, which boasts around 29 MPG combined. However, these alternatives all make different tradeoffs. The M240i offers a mix of power and refinement that speaks to enthusiasts who might accept slightly lower MPG for more driver involvement. Comparing all Bmw fuel economy data can show the choices within the BMW range.

Tips to maximize efficiency

Keep your tires properly inflated. This reduces rolling resistance and can noticeably improve fuel economy, especially on longer drives. The recommended tire pressure for the M240i can be found on the door jamb sticker.

Avoid aggressive acceleration and hard braking. The M240i’s engine is responsive, but every full-throttle launch and sudden stop consumes extra fuel. Smooth acceleration will save gas and enhance the car’s overall driving experience.

Use the car’s driving modes intelligently. The M240i typically has different driving modes (e.g., Eco, Comfort, Sport) that adjust the engine and transmission mapping. Select “Comfort” or “Eco” for cruising and save “Sport” for when you want to exploit the engine’s performance.

Consider using cruise control on the highway. Maintaining a constant speed can significantly improve fuel economy, particularly on long, flat stretches. Be mindful of other traffic and road conditions when using cruise control.

Service your M240i regularly. Proper maintenance, including oil changes, air filter replacements, and spark plug replacements, ensures the engine is running efficiently. Follow the manufacturer’s recommended service schedule.
