24 MPG combined is the price of admission for experiencing one of the last truly great small BMW coupes. The 2019 M240i isn’t about sipping fuel; it’s about delivering a thrilling driving experience in a compact package. Buyers accept this fuel economy because they prioritize performance, agility, and the signature BMW driving feel over outright efficiency.

City and highway performance

The M240i showcases the difference between city and highway fuel consumption. The EPA estimates 21 MPG in the city, reflecting the stop-and-go driving conditions that stifle efficiency. On the open road, however, the M240i shines, achieving 30 MPG on the highway. This stark contrast underscores the car’s dual personality, a responsive city runabout and a capable highway cruiser.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2019 BMW M240i is $2,400. This figure is based on driving 15,000 miles per year with a mix of city and highway driving, using national average fuel prices. This estimated cost reflects a significant ongoing expense of owning and operating a performance vehicle.

Real-world expectations

While the EPA provides a standardized benchmark, real-world MPG can vary considerably based on driving style, traffic conditions, and even the specific route. Drivers who frequently push the M240i’s performance will likely see figures closer to the city estimate, or even lower. Those who adopt a more conservative driving style and spend a significant portion of their time on the highway could potentially exceed the EPA’s highway estimate. The M240I MPG across all years is affected by similar variables.

How it compares

Compared to other performance coupes, the M240i resides in a competitive space. The 2019 Audi S3, with its turbocharged 2.0-liter engine, achieves an EPA-estimated 25 MPG combined. The Nissan 370Z, a more raw and less refined sports car, averages around 22 MPG combined. The Subaru WRX, while offering all-wheel drive and similar practicality, lands around 23 MPG combined. The M240i’s fuel consumption reflects its more powerful engine and focus on accessible performance, a trade-off many buyers are willing to make. You can also see all Bmw fuel economy data to compare it to other models for the brand.

Tips to maximize efficiency

Smooth and consistent throttle inputs are key to maximizing fuel economy in the M240i. Avoid sudden acceleration and hard braking, as these actions consume considerably more fuel. Use the car’s Eco Pro driving mode, which remaps the throttle response and adjusts other parameters to prioritize fuel efficiency.

Proper tire inflation plays an important role in reducing rolling resistance and, consequently, improving fuel economy. Regularly check and maintain the recommended tire pressure, as specified on the doorjamb sticker. Underinflated tires increase friction and drag, leading to lower MPG figures.

Minimize the use of accessories that put extra strain on the engine, such as air conditioning and heated seats, especially during short trips. These systems draw power from the engine, which in turn increases fuel consumption. Pre-conditioning the cabin while the car is plugged in (if possible) can reduce this burden.

Consider the grade of fuel you’re using. While the M240i doesn’t necessarily require premium fuel, it’s designed to perform optimally with it. Using lower octane fuel may result in reduced performance and slightly lower fuel economy, negating any potential cost savings at the pump.

Plan your routes strategically to avoid heavy traffic congestion and stop-and-go scenarios. Idling in traffic wastes fuel unnecessarily. Exploring alternative routes or adjusting your commute time can help you maintain a more consistent speed and improve your overall fuel efficiency.
