The 2018 BMW M4 Coupe’s 3.0L 6-cyl engine gets 20 MPG combined, but that’s not the primary reason people buy it. It’s the price for a visceral driving experience, a compromise accepted with a knowing nod. This isn’t a car for fuel-sipping commutes or cross-country road trips prioritizing economy. It’s designed for performance, and its fuel consumption reflects that. The target demographic understands this; they prioritize the sound of the inline-six, the precision of the handling, and the driving pleasure above all else, and they accept the fuel bill as part of the deal.

City and highway performance

The M4’s EPA-estimated fuel economy breaks down to 17 MPG in the city and 24 MPG on the highway. The city figure indicates that stop-and-go traffic and aggressive acceleration will significantly impact fuel consumption, something that’s virtually guaranteed behind the wheel of the M4. The highway number is more respectable, relatively speaking. While 24 MPG is far from stellar, it is achievable on longer stretches of open road when resisting the urge to exploit the engine’s power. However, even at highway speeds, a heavy foot will quickly erode those gains. The turbochargers and the temptation to pass everyone are to blame.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,900 for the 2018 BMW M4 Coupe. This figure is based on driving 15,000 miles per year and using the national average fuel price (premium fuel, which the M4 requires). This number provides a benchmark, but individual fuel costs can vary based on driving habits, local fuel prices, and the frequency with which the M4 is driven on back roads or at a track. If you are worried about this $2,900 figure, this car is not for you. Go find all Bmw fuel economy data to see if another model is more in line with your budget.

Real-world expectations

Do not expect to consistently achieve the EPA numbers in real-world driving conditions. The M4’s performance-oriented nature encourages aggressive driving, which directly translates to reduced fuel economy. Drivers who frequently engage in spirited acceleration, track days, or predominantly city driving may see significantly lower MPG figures, potentially dipping well below the EPA estimates. A combined average of 18 MPG is likely a more realistic target for many M4 owners, while those with a more relaxed driving style might approach the 20 MPG mark.

How it compares

The M4’s fuel economy is comparable to other high-performance coupes in its class, but there are some contrasts. The Mercedes-AMG C63 Coupe, with its V8 engine, typically achieves around 18 MPG combined. The Audi RS5 Coupe lands around 21 MPG combined, which is only slightly better. The Porsche 911 Carrera, while offering superior performance in some respects, typically falls close to 22 MPG combined. These figures highlight the trade-off between performance and fuel efficiency in this segment. You can also compare M4 MPG across all years to see if another used model balances performance with fuel efficiency to a higher degree.

Tips to maximize efficiency

While the M4 isn’t designed for fuel efficiency, there are steps drivers can take to optimize gas mileage without sacrificing all the fun. Resist the urge to constantly accelerate hard; smooth, gradual acceleration minimizes fuel consumption. Using the M4’s driving modes can also help. Selecting “Efficiency” or “Comfort” mode will alter the engine mapping and throttle response to prioritize fuel conservation over outright performance.

Maintaining proper tire inflation is critical for optimal fuel economy on any vehicle, and the M4 is no exception. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressures regularly and inflate them to the recommended levels specified on the door jamb sticker.

Avoid unnecessary idling. Letting the engine idle for extended periods wastes fuel, especially on a strong engine like the M4’s inline-six. If you’re stopped for more than a minute, it’s generally more efficient to turn off the engine. The M4 has auto start/stop that is helpful to minimize the time spent idling.

Regular maintenance plays an important role in maintaining optimal fuel efficiency. A clean air filter, properly functioning spark plugs, and fresh engine oil all contribute to efficient combustion. Follow the manufacturer’s recommended maintenance schedule to ensure your M4 is performing at its best. With good maintenance, you could see the estimated MPG of the M4.
