19 MPG combined isn’t the reason people buy a 2023 BMW M4 Competition Coupe. Owners prioritize 503 horsepower, razor-sharp handling, and the visceral thrill of a high-revving inline-six. Fuel efficiency is, at best, an afterthought. Expecting Prius-like mileage from a car engineered to dominate racetracks is simply unrealistic.

City and highway performance

The M4 Competition’s city MPG is rated at 16, reflecting the stop-and-go driving conditions where the engine spends more time idling and accelerating from a standstill. The instant torque of the turbocharged engine, while exhilarating, contributes to increased fuel consumption in urban environments.

On the open highway, the M4 Competition fares slightly better, achieving 23 MPG. This is thanks to the eight-speed automatic transmission which, even in its most aggressive settings, can select taller gears at cruising speeds to optimize fuel usage. However, even on the highway, a heavy foot will quickly negate any potential fuel savings.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 BMW M4 Competition Coupe at $3,050. This figure is based on driving 15,000 miles per year, with 45% of those miles driven in the city and 55% on the highway, and using the EPA’s projected national average fuel price. Individual costs will vary depending on local fuel prices, driving habits, and the type of fuel used. The M4 Competition requires premium fuel, which adds to the overall expense. For context, drivers can also see M4 MPG across all years.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy for the M4 Competition is highly dependent on driving style. Owners who frequently explore the upper reaches of the tachometer or engage in spirited driving can expect figures significantly lower than the EPA estimates. Conversely, those who prioritize smooth acceleration and maintain consistent speeds may be able to achieve numbers closer to, or even slightly above, the highway rating. Ultimately, the M4 Competition is a performance car, and its fuel economy will reflect that.

How it compares

Compared to its peers, the M4 Competition’s fuel economy is typical for its class. The Audi RS5 Coupe, with its 2.9-liter twin-turbo V6, achieves a combined 21 MPG, a modest improvement. The Mercedes-AMG C63 S Coupe, with its 4.0-liter twin-turbo V8 (prior to the 2024 redesign), is rated at 19 MPG combined, matching the M4 Competition. The Porsche 911 Carrera offers better fuel economy, achieving 21 MPG combined, due to its slightly less powerful engine and lighter weight. The trade-off, of course, is a different driving experience. While the 911 emphasizes precision and balance, the M4 Competition offers a more aggressive and raw performance feel.

Tips to maximize efficiency

Resist the urge to constantly use launch control or engage in aggressive acceleration. The M4 Competition’s power is addictive, but exercising restraint will noticeably improve fuel consumption. Treat the throttle with respect, especially in city driving.

Use the M4 Competition’s customizable drive modes. Selecting the “Efficient” or “Comfort” mode will soften the throttle response, encourage earlier upshifts, and reduce the energy wasted with aggressive driving. These modes are not as exciting as “Sport” or “Sport Plus,” but they can make a difference on longer journeys.

Ensure that your tires are properly inflated. Underinflated tires increase rolling resistance, which negatively impacts fuel economy. Check your tire pressures regularly and maintain them at the recommended levels indicated on the driver’s side door jamb.

Minimize unnecessary weight. Carrying extra cargo in the trunk or back seats adds weight to the vehicle, forcing the engine to work harder and consume more fuel. Remove any items that are not essential for your journey.

Avoid prolonged idling. Letting the engine idle for extended periods consumes fuel without covering any distance. If you are stopped for more than a minute or two, it’s generally more efficient to turn off the engine and restart it when you’re ready to go.
