While a combined 23 MPG may not be the main reason to buy a 2022 BMW 840i xDrive Gran Coupe, it’s an important figure for those considering its performance, luxury, and sleek four-door coupe styling. This isn’t a hybrid or an economy car; it’s a statement vehicle with a strong engine and all-wheel drive, and the fuel economy reflects this.

City and highway performance

EPA estimates suggest 20 MPG in the city and 27 MPG on the highway. The city figure reflects stop-and-go traffic, where the 840i’s 3.0L turbocharged inline-six engine works harder, and frequent acceleration uses more fuel. The highway number is more achievable, thanks to the smooth-shifting eight-speed automatic transmission and the engine’s ability to cruise comfortably at higher speeds. Buyers spending most of their time in urban environments should expect figures closer to the city rating, while those who frequently drive on the highway will likely see numbers closer to or even slightly above the EPA highway estimate. It’s a car that enjoys covering ground, and when driven carefully, relatively efficiently. Understanding the difference between these two ratings is key to predicting your personal fuel costs and planning accordingly.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 BMW 840i xDrive Gran Coupe at $2,500. This figure is based on driving 15,000 miles per year and using national average fuel prices. Individual costs will vary depending on location, driving habits, and gasoline prices. The $2,500 figure provides a standardized measure for comparing fuel costs across different vehicles, but it’s important to remember it’s just an estimate. Someone who drives significantly less than 15,000 miles or who lives in a state with lower gas prices will likely spend less. Conversely, a driver who accelerates quickly, takes frequent short trips, or lives in an area with higher fuel costs can expect to exceed this annual figure. It’s a benchmark that is useful for comparison, not a guarantee.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy often differs. The 840i Gran Coupe’s powerful engine can tempt drivers to explore its performance, which inevitably impacts efficiency. Factors like driving style, tire pressure, and even the use of accessories like air conditioning can influence fuel consumption. Someone who appreciates the car’s performance will likely see MPG figures that skew slightly lower than the EPA estimates, while careful drivers might achieve numbers closer to the official ratings. Pay attention to your driving habits and monitor your fuel consumption over time to understand your 840i’s fuel economy.

How it compares

When cross-shopping, consider the Audi A7. The A7, with its similarly sleek profile and available 3.0-liter V6, achieves about 24 MPG combined, making it slightly more fuel-efficient than the 840i xDrive Gran Coupe. The Mercedes-Benz CLS 450, another four-door coupe competitor, posts around 25 MPG combined. These differences, while seemingly small, can add up over time and should be considered during the purchase process. For buyers prioritizing less gas above all else, these alternatives might present a slightly more economical option. However, the driving experience and other factors often carry more weight for the typical 840i buyer. You can also review 840I MPG across all years in our fuel economy database.

Tips to maximize efficiency

Use the BMW’s driving modes. Selecting “Eco Pro” mode adjusts the engine and transmission settings to prioritize fuel efficiency. The throttle response becomes less aggressive, and the transmission shifts earlier to keep the engine operating at lower RPMs. This mode is particularly useful for everyday commuting and can help maximize mileage.

Ensure your tires are properly inflated. 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 indicated on the doorjamb sticker. Properly inflated tires not only improve fuel economy but also enhance handling and extend tire life.

Avoid aggressive driving habits. Quick acceleration and hard braking significantly reduce fuel economy. Maintain a smooth and consistent speed, anticipate traffic conditions, and avoid unnecessary acceleration. Careful driving saves fuel and provides a more relaxed driving experience.

Minimize idling. Idling wastes fuel, especially in modern engines. If you anticipate being stationary for more than a minute or two, turn off the engine. Restarting the engine consumes less fuel than prolonged idling, so eliminating periods of idling can improve efficiency. Compare all Bmw fuel economy data with the current year model.
