25 MPG combined won’t win any hypermiling awards, but for the 2022 BMW 840i Coupe, it reflects the car’s mission: effortless performance blended with responsible grand touring. This isn’t a Prius competitor; it’s a statement of refined power and a promise of cross-country comfort. The buyer appreciates driving dynamics and the prestige of the BMW roundel more than chasing every last mile per gallon. They understand the trade-off and are willing to make it.

City and highway performance

The EPA estimates for the 2022 BMW 840i Coupe reveal a split personality. In the city, the 840i manages 23 MPG. This isn’t terrible, especially considering the engine’s 335 horsepower output. The responsive throttle and quick-shifting eight-speed automatic transmission encourage spirited driving, which impacts fuel consumption. On the open highway, the 840i fares better, achieving 30 MPG. Here, the engine settles into a relaxed cruise, showcasing its grand touring capabilities. The long gearing of the transmission and the efficient inline-six cylinder engine contribute to this respectable number. These figures demonstrate that the 840i is most efficient when covering long distances at a steady pace, what it was designed to do.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 BMW 840i Coupe at $2,300. This is calculated based on driving 15,000 miles per year, using the prevailing national average fuel price (which can fluctuate). This cost is unlikely to deter the typical 840i buyer. They prioritize the driving experience and the ownership benefits that come with a luxury coupe. Understanding this cost allows them to budget accordingly and view it as part of the overall ownership experience, including maintenance and insurance.

This $2,300 figure provides a benchmark, but individual costs will vary based on driving habits and regional fuel prices. You can see all Bmw fuel economy data here.

Real-world expectations

While the EPA figures provide a standardized benchmark, real-world MPG for the 2022 BMW 840i Coupe will vary. Aggressive driving, frequent hard acceleration, stop-and-go traffic, and inclement weather can all negatively impact fuel economy. However, careful driving, using the car’s Eco Pro mode, and adhering to posted speed limits can help drivers achieve or exceed the EPA estimates. The 840i is a performance vehicle, and exploiting its capabilities will lead to increased gas consumption. The driver’s style plays a role in determining the ultimate MPG.

How it compares

Compared to its competitors, the 2022 BMW 840i Coupe holds its own in terms of fuel economy. The Mercedes-Benz C300 Coupe achieves a slightly higher 28 MPG combined but lacks the 840i’s strong inline-six engine. The Lexus RC 350 is rated at 23 MPG combined, falling behind the 840i. The Porsche 911 Carrera gets around 21 MPG combined. These comparisons show that the 840i balances performance and efficiency, offering a respectable MPG figure without sacrificing the driving experience. For buyers prioritizing lower fuel costs, the Mercedes-Benz C300 Coupe might be a better choice, but those seeking a blend of power and relative thriftiness will find the 840i appealing.

Tips to maximize efficiency

Be mindful of your right foot. The 840i, with its turbocharged engine, responds eagerly to throttle input. Avoiding hard acceleration and sudden braking can improve fuel economy. Smooth, consistent driving is key.

Use the car’s driving modes. The 840i offers various driving modes, including Eco Pro. Engaging this mode adjusts the throttle response and shift points to prioritize fuel efficiency. While it might slightly dampen the car’s responsiveness, it can make a noticeable difference on longer journeys.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and use more fuel. Regularly check and maintain the recommended tire pressure, which can be found on the driver’s side doorjamb.

Minimize idling. Letting the engine idle for extended periods consumes fuel without covering any distance. If you’re stopped for more than a minute or two, turn off the engine. Modern engines are designed to restart quickly and efficiently.

Keep up with scheduled maintenance. A well-maintained engine runs more efficiently. Follow the manufacturer’s recommended maintenance schedule, including regular oil changes, air filter replacements, and spark plug inspections. This simple step can keep your 840i running smoothly and efficiently for years to come.
