25 MPG combined is respectable for the 2017 BMW M240i Coupe. Potential buyers will understand this number when they consider what the car delivers: a near-perfect blend of performance, agility, and everyday usability. This isn’t a hybrid chasing ultimate efficiency figures; it’s a driver’s car that offers decent fuel economy.

City and highway performance

The M240i’s EPA figures reflect its dual personality. In the city, the 21 MPG rating suggests a thirstier engine. This reflects the stop-and-go driving and frequent bursts of acceleration that tempt many owners. On the highway, the story improves substantially, with a commendable 32 MPG. This efficiency on longer journeys makes the M240i a capable road trip companion. Considerate driving is rewarded with a fuel range that belies its sporty character. This difference between city and highway fuel economy is something for buyers to note, depending on their primary driving environment.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,300 for the 2017 BMW M240i. This figure is based on driving 15,000 miles per year, using current national average fuel prices for premium gasoline, which this car requires. Individual fuel costs will vary depending on local fuel prices and your specific driving habits. Drivers who frequently accelerate hard may see higher fuel bills, while those who prioritize efficiency can aim to get closer to, or even better, the EPA estimates. Remember that fuel prices fluctuate frequently, impacting your real-world expenses.

Real-world expectations

While the EPA estimates provide a benchmark, real-world fuel economy often deviates depending on various factors, including driving style, traffic conditions, tire pressure, and even ambient temperature. Expect the city figure to be achievable with conscious effort, but the temptation to unleash the turbocharged inline-six can easily reduce those gains. The highway figure is more reliably attained during steady-state cruising. Online forums and owner surveys often provide insight into M240I MPG across all years in different conditions. They offer a more nuanced understanding of what to expect.

How it compares

The M240i’s fuel economy is in a competitive range. A comparable Audi S3, with its 2.0T engine and quattro all-wheel drive, achieves around 25 MPG combined as well, but its city figure is often slightly higher. The Mercedes-AMG CLA 45, despite its higher performance output, lands roughly at the same mark overall. The M240i offers a different driving experience than both of these vehicles, favoring a more traditional rear-wheel-drive setup. For those considering alternatives outside the German brands, the Ford Mustang EcoBoost offers similar performance and potentially higher MPG, but lacks the M240i’s refinement and premium feel. Buyers cross-shopping these vehicles are often willing to sacrifice a few MPG for the unique character and driving dynamics of the BMW.

Tips to maximize efficiency

The M240i might be a performance machine, but small changes in your driving habits can help reduce fuel consumption. Avoid aggressive acceleration and hard braking, as these actions require the engine to work harder and burn more fuel. Maintaining a steady speed on the highway is much more efficient than constantly speeding up and slowing down.

Ensure your M240i’s tires are properly inflated to the recommended pressure. Underinflated tires increase rolling resistance, which negatively impacts fuel economy. Regular tire pressure checks are a simple way to improve your MPG.

Reduce unnecessary weight in your vehicle. Carrying around extra items in the trunk or rear seats adds weight, forcing the engine to work harder. Remove any non-essential items to lighten the load and improve fuel efficiency.

Use the automatic transmission’s Eco Pro mode (if equipped) when appropriate. This mode adjusts the engine and transmission settings to prioritize fuel efficiency, lowering the revs and shifting earlier. While it might slightly reduce performance, it can make a noticeable difference in MPG, particularly in city driving.

Keep your M240i properly maintained. Regular oil changes, air filter replacements, and spark plug maintenance ensure the engine is running optimally. A well-maintained engine is a more efficient engine. Browse all Bmw fuel economy data to compare models and years.
