The 2020 BMW M240i xDrive Coupe 3.0L 6-cyl isn’t bought for its 25 MPG combined fuel economy. Instead of hypermiling, this car offers a brilliant turbocharged inline-six and all-wheel drive in a compact, athletic coupe. It’s about accessible performance with BMW polish. Fuel efficiency is simply a compromise enthusiasts accept.

City and highway performance

The M240i xDrive’s EPA ratings are 22 MPG in the city and 30 MPG on the highway. The city figure is realistic for stop-and-go driving, showing the engine’s thirst for fuel when delivering potent low-end torque. The engine management system helps to some extent, but power comes at a price. The 30 MPG highway figure is achievable during steady cruising. The eight-speed automatic transmission (S8) is well-geared for both acceleration and relaxed highway travel, and the overdrive ratios help keep the engine running quietly and efficiently when you’re not pushing the limits. Drivers unfamiliar with the M240I MPG across all years may be pleasantly surprised at the highway numbers, given the car’s overall performance.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2020 BMW M240i xDrive Coupe is $2,300. This is based on driving 15,000 miles per year and national average fuel prices. This is an estimate, and your actual fuel costs may vary depending on your driving habits, location, and changes in gasoline prices. Also, the M240i’s turbocharged engine might perform best with premium fuel, which can increase your overall cost.

Real-world expectations

The EPA provides a useful benchmark, but real-world fuel economy often differs from the official numbers. An M240i owner who enjoys spirited driving will likely see fuel economy closer to the low 20s, especially with frequent use of Sport mode. Those who prioritize efficiency and spend most of their time on the highway might achieve figures close to, or even above, the 30 MPG highway rating. Other things, like tire pressure, ambient temperature, and the specific blend of gasoline used, can change fuel economy.

How it compares

The Audi S3, another all-wheel-drive performance compact with a turbocharged engine, has an EPA combined rating of 25 MPG, matching the M240i. The S3’s 2.0-liter four-cylinder engine delivers power in a slightly different way. The Mercedes-AMG CLA 35 offers a similar blend of performance and practicality, with an EPA combined rating of 25 MPG, demonstrating the trade-offs in this performance segment. A rear-wheel drive BMW 230i Coupe, while less powerful, gets an EPA combined rating of 28 MPG, showing the fuel economy benefits of a smaller engine and fewer driven wheels. These comparisons are important because the M240i buyer knows that performance has a price, and they’re evaluating how much they’re willing to pay at the pump for their driving experience. Comparing all Bmw fuel economy data is useful to understand how this model fits in to the overall line of vehicles.

Tips to maximize efficiency

Resist the urge to constantly push the engine. The M240i’s turbocharged inline-six works best when revved, but gentle acceleration and consistent speeds will improve fuel economy.

Use Eco Pro driving mode. It won’t turn the M240i into a Prius, but this mode adjusts the throttle response and transmission mapping to prioritize fuel efficiency over outright performance. It’s helpful for highway cruising or stop-and-go traffic.

Make sure your tires are properly inflated. Under-inflated tires increase rolling resistance, which makes the engine work harder and consume more fuel. Regularly checking and maintaining the recommended tire pressure can have a visible impact.

Avoid unnecessary idling. Modern engines are designed to be efficient even at idle, but long idling still consumes fuel. If you’re stopped for more than a minute or two, it’s generally more efficient to turn off the engine.

Reduce aerodynamic drag. Roof racks and other accessories can increase aerodynamic drag, which reduces fuel economy, especially at higher speeds. Remove them when not in use to minimize drag and improve efficiency.
