19 MPG combined. Let’s be honest: Anyone cross-shopping a 2021 BMW M4 Coupe with a manual transmission isn’t prioritizing fuel economy. They’re seeking a raw, visceral driving experience, and the fuel bill is simply the price of admission. This isn’t a commuter car; it’s a precision instrument designed for carving corners and extracting maximum thrills from every mile, and the energy consumption reflects that mission.

City and highway performance

The M4’s EPA ratings break down to 16 MPG in the city and 23 MPG on the highway. The city figure reflects the reality of stop-and-go traffic, aggressive acceleration away from stoplights, and the engine’s tendency to remain thirsty at low speeds. The highway figure, while better, is still relatively modest. Blame the M4’s inherent performance profile: even at cruising speeds, the engine rarely idles quietly. Expect frequent downshifts for passing maneuvers, accompanied by a corresponding dip in fuel efficiency. While 23 MPG is achievable in steady-state highway driving, maintaining that requires disciplined throttle control, something that’s not always easy when the open road beckons.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 BMW M4 Coupe (manual) at $3,050. This figure is based on driving 15,000 miles per year and using national average fuel prices, priced at $5.08 dollars, at the time these original figures were created. Keep in mind that premium fuel is required, so fluctuations in 91-octane prices will directly impact this annual cost. And most M4 drivers probably exceed the 15,000-mile estimate, further inflating that number.

Real-world expectations

Forget the EPA numbers. Real-world MPG in the 2021 M4 hinges directly on driving style. A cautious driver might see numbers closer to the EPA estimates, but someone regularly exploiting the engine’s potential will likely average significantly less. Track days, spirited weekend drives, and frequent use of the M driving modes will all punish your fuel economy. Conversely, meticulously short-shifting, avoiding hard acceleration, and prioritizing smooth highway cruising can nudge your MPG closer to the EPA figure, but will also subdue much of the vehicle’s charm. Driving this car gently defeats the purpose of owning it.

How it compares

Competitors offer a mixed bag in terms of fuel economy. The Audi RS5 Coupe, while offering similar levels of performance, manages around 18 MPG combined. The Mercedes-AMG C63 S Coupe, with its more potent V8, consumes fuel at a noticeably higher rate, hovering around 18 MPG combined as well. The Porsche 911 Carrera, though from a slightly different performance category, generally offers a more favorable fuel economy, approaching 20-22 MPG combined, depending on the specific configuration. For a broader look, consult all Bmw fuel economy data. The reason these comparisons matter is simple: buyers in this segment often weigh performance against usability. A slight MPG advantage can tip the scales for those who balance track ambitions with daily drivability. But for many, the M4’s unique combination of precision handling and raw power outweighs any marginal fuel cost disadvantage.

Tips to maximize efficiency

While maximizing fuel economy isn’t usually the M4 owner’s top priority, there are strategies to mitigate fuel consumption without sacrificing too much driving enjoyment. Short-shifting and using higher gears when cruising at constant speeds can significantly reduce fuel consumption. The manual transmission rewards smooth operation, so avoid jerky starts and sudden acceleration whenever possible.

Check tire pressures regularly. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Adhering to the recommended tire pressure found on the door jamb sticker optimizes both fuel efficiency and tire life. Also, avoid extra weight in the car.

Avoid idling unnecessarily. If you’re stopped for more than a minute or two, turn off the engine. Modern vehicles are designed to restart quickly and efficiently, eliminating the need to idle “to warm up” the engine. As well, select Eco Pro driving mode, when sensible.

Plan your routes to avoid stop-and-go traffic. Navigating congested urban environments forces frequent acceleration and braking, two major culprits in decreased fuel economy. Opting for less-traveled routes, even if slightly longer, can sometimes save fuel in the long run, however avoid the temptation to increase speeds to compensate. If you’re interested in the M4 MPG across all years, this can inform your purchasing decision even further.
