24 MPG combined might seem disappointing, but the 2021 BMW M240i Coupe isn’t bought for lower fuel costs. This is a compact performance machine with a turbocharged inline-six, and that 24 MPG figure is a compromise enthusiasts accept for the car’s exciting performance.

City and highway performance

The M240i’s EPA ratings estimate 21 MPG in the city and 30 MPG on the highway. The city figure reflects the engine’s eagerness to rev and the temptation to exploit the available power. On the open road, the eight-speed automatic transmission and the engine’s efficiency at cruising speeds allow it to stretch a gallon of fuel further. Those who prioritize backroad driving over city traffic will see better results overall.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2021 BMW M240i is $2,400. This estimate is based on driving 15,000 miles per year and using national average fuel prices. Individual fuel costs will vary depending on driving habits, local fuel prices, and the type of fuel used, but the EPA estimate provides a benchmark for comparison.

Real-world expectations

Real-world fuel economy often differs from EPA estimates, and the M240i is no exception. Aggressive driving will easily drop the combined MPG into the high teens or low twenties. More conservative drivers, particularly those who drive a significant number of highway miles, might see figures closer to the EPA’s 30 MPG highway rating. The M240i’s onboard computer provides a running average of fuel consumption, which owners can use to monitor their driving habits and adjust accordingly.

How it compares

Compared to other performance-oriented coupes, the M240i’s fuel economy is in a respectable position. The Audi S3 Sedan, with its 2.0-liter turbocharged four-cylinder and Quattro all-wheel drive, achieves a combined 26 MPG. A Porsche 718 Cayman delivers around 24 MPG combined with its base 2.0-liter engine. For those seeking greater efficiency, the four-cylinder BMW 230i Coupe achieves 28 MPG combined. Ultimately, buyers of the M240I MPG across all years prioritize performance over economy. They’re willing to accept the trade-off for the car’s sharp handling, powerful engine, and unique character.

Tips to maximize efficiency

Avoid aggressive acceleration. The M240i’s turbocharger loves to spool up, but each burst of power uses more fuel. Smooth, gradual acceleration will minimize fuel consumption, especially in city driving. BMW offers an “Eco Pro” driving mode. This mode remaps the throttle response, reduces climate control energy consumption, and encourages more fuel-efficient driving habits.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check tire pressure regularly, and inflate to the recommended levels on the door jamb sticker or in the owner’s manual.

Reduce unnecessary weight. Extra cargo in the trunk adds weight and decreases fuel economy. Remove any items that aren’t needed to lighten the load.

Anticipate traffic conditions and avoid hard braking. Reading the road and planning your route can help you avoid sudden stops and starts, which waste fuel. Coasting to a stop is more efficient than braking at the last moment.

Consider the long run. When choosing options, consider lightweight wheels. These can reduce the unsprung weight and improve efficiency. See all Bmw fuel economy data for the best results.
