25 MPG combined isn’t going to win any hypermiling contests, but it’s justifiable for the 2020 BMW M240i Coupe M Performance. This isn’t a Prius competitor; it’s a compact, rear-wheel-drive (or optional xDrive all-wheel drive) coupe built for driving enjoyment. The MPG reflects that priority, balancing performance with acceptable efficiency. This car appeals to enthusiasts who value the rush of a turbocharged inline-six, and they understand that smiles per gallon often outweigh miles per gallon.

City and highway performance

The M240i’s EPA-estimated city MPG is 22, a reasonable figure considering the car’s eagerness to accelerate. The responsiveness of the 3.0L engine paired with the quick-shifting 8-speed automatic (S8) encourages frequent bursts of speed. On the highway, the M240i fares better, achieving 30 MPG. This reflects the engine’s ability to cruise comfortably at higher speeds, with the transmission settling into taller gears that prioritize fuel conservation. The highway MPG makes it perfectly acceptable for longer road trips, where the comfortable seats and compliant suspension add to the experience.

Annual fuel cost

The EPA estimates that you’ll spend $2,300 per year fueling your 2020 BMW M240i. This figure is calculated based on driving 15,000 miles annually, using a composite of 55% city and 45% highway driving, and factoring in the national average fuel prices for premium gasoline, which is recommended for optimal performance in the M240i. If you drive significantly more or less than 15,000 miles per year, or if fuel prices fluctuate dramatically, your actual fuel costs will vary accordingly. However, $2,300 provides a solid expectation.

Real-world expectations

While the EPA estimates offer a standardized comparison point, real-world fuel economy varies based on driving style, traffic conditions, and environmental factors. M240i owners who frequently engage in spirited driving, especially on twisty backroads or during track days, are unlikely to achieve the EPA’s 25 MPG combined figure. In these scenarios, fuel economy may dip into the high teens or low twenties. Conversely, drivers who prioritize smooth acceleration and consistent speeds, especially on the highway, may see figures closer to, or even slightly exceeding, the 30 MPG highway estimate. The M240I MPG across all years is sensitive to driver behavior.

How it compares

The Audi S3, a key competitor with its turbocharged 2.0L engine and standard all-wheel drive, offers a similar driving experience, with an EPA rating of 26 MPG combined. The Mercedes-AMG CLA 35, another option in this segment, achieves 25 MPG combined. The Nissan Z, while not a luxury competitor, offers a similar focus on performance, and achieves 22 MPG combined with its V6 engine. The BMW shines in this comparison because it offers a combination of a powerful inline-six engine and rear-wheel-drive dynamics (or xDrive), making it a potent choice in its class. For drivers checking all all Bmw fuel economy data, the M240i strikes a satisfying balance.

Tips to maximize efficiency

Avoid aggressive acceleration and hard braking. The M240i’s responsive engine is tempting, but consistent, smooth driving will yield improvements in fuel economy. Anticipate traffic flow to minimize unnecessary stops and starts.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and burn more fuel. Check your tire pressures regularly and inflate them to the recommended levels listed on the driver’s side doorjamb.

Use the Eco Pro driving mode when appropriate. The M240i’s driving mode selector allows you to prioritize fuel efficiency over performance. Eco Pro mode adjusts the engine mapping, throttle response, and shift points to maximize MPG, particularly during highway cruising.

Reduce unnecessary weight. Excess cargo in the trunk or back seat adds weight, which impacts fuel economy. Remove any items that are not essential for your daily driving.

Consider using cruise control on long highway drives. Maintaining a consistent speed with cruise control helps to optimize fuel consumption by preventing speed fluctuations. This is especially effective on relatively flat stretches of highway.
