The 2021 BMW M240i xDrive Coupe achieves 24 MPG combined, a figure that won’t shatter any fuel efficiency records, but is largely irrelevant to the car’s target demographic. This isn’t a vehicle purchased for its minimal fuel consumption; it’s bought for its potent turbocharged inline-six, its nimble handling, and its understated performance. The kind of driver drawn to the M240i prioritizes thrills over pump prices, accepting the fuel economy as a necessary trade-off for the car’s engaging driving experience.

City and highway performance

The EPA estimates the M240i xDrive Coupe will achieve 21 MPG in the city and 30 MPG on the highway. The urban figure, while respectable, reflects the realities of stop-and-go traffic and the engine’s eagerness to rev when prompted. The highway number, thankfully, is more palatable, suggesting that longer journeys can at least be undertaken without requiring constant fuel stops. The automatic transmission’s eight gears certainly contribute to this, allowing the engine to settle into a more efficient cruising speed. But be aware: the moment you dip into the M240i’s ample power reserves for an enthusiastic overtake, that highway MPG figure will quickly begin to decline.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,400 for the 2021 BMW M240i xDrive Coupe. This calculation is based on driving 15,000 miles per year and using national average fuel prices. Whether this figure aligns with your own experience will depend entirely on your driving habits and the price of fuel in your area. Those who frequently exploit the engine’s performance potential will almost certainly exceed this amount. Consider this figure a baseline, a starting point for understanding the potential financial impact of owning a performance coupe like the M240i.

Real-world expectations

While the EPA provides a useful benchmark, real-world fuel economy can vary significantly based on individual driving styles and conditions. The M240i begs to be driven with enthusiasm, and resisting that urge will be a challenge for most owners. Frequent bursts of acceleration, aggressive cornering, and extended periods in Sport mode will undoubtedly lead to lower MPG. Conversely, those who adopt a more relaxed driving style and spend more time on the highway might see figures closer to, or even slightly exceeding, the EPA estimates. Understanding the car’s character and your own driving habits is crucial for setting realistic expectations.

How it compares

Compared to its competitors, the 2021 M240i xDrive falls roughly in the middle of the pack. The Audi S3, with its 22 MPG combined, offers slightly worse fuel economy, while still delivering comparable performance. The Mercedes-AMG CLA 35 manages about 25 MPG combined. These differences, while measurable, are unlikely to sway a buyer’s decision significantly in this segment. Drivers shopping for performance coupes are typically less concerned with squeezing every last mile from a gallon of fuel and more interested in driving dynamics and overall value. For example, you might find that all Bmw fuel economy data makes the M240i a relative sweet spot for performance. You can also dive into M240I MPG across all years and consider buying used.

Tips to maximize efficiency

Take advantage of the M240i’s Eco Pro mode. While it might temper the car’s performance, it also optimizes various vehicle systems for maximum fuel efficiency. This mode adjusts throttle response, transmission mapping, and even climate control settings to minimize fuel consumption, proving useful for mundane commutes.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which forces the engine to work harder and consumes more fuel. Check your tire pressures regularly and maintain them at the recommended levels, typically found on a sticker inside the driver’s side doorjamb.

Anticipate traffic flow and avoid unnecessary braking and acceleration. Maintaining a steady speed and allowing the car to coast whenever possible will help conserve fuel. Aggressive driving habits, such as hard braking and rapid acceleration, significantly reduce fuel economy.

Use the automatic transmission strategically. The M240i’s eight-speed transmission is designed to optimize fuel efficiency. Allow it to shift smoothly through the gears and avoid unnecessarily revving the engine. If you prefer more engagement, use the paddle shifters judiciously, but be mindful of the impact on fuel consumption.
