The 2020 BMW 840i Gran Coupe isn’t defined by its 24 MPG combined fuel economy. For the buyer drawn to this four-door style icon, that number slides into the background. These drivers prioritize the sleek silhouette, the luxurious interior, and the effortless surge of its turbocharged inline-six over squeezing every last mile from a gallon of premium fuel. They accept the fuel economy as a necessary compromise for the prestige and performance that comes with owning a car like the 840i Gran Coupe.

City and highway performance

The EPA estimates 22 MPG in the city and 29 MPG on the highway for the 2020 BMW 840i Gran Coupe. The city figure reflects the stop-and-go conditions, the idling at traffic lights, and the frequent bursts of acceleration inherent to urban driving. While not terrible, the city MPG highlights the engine’s need to work harder, using its power reserves more frequently. Highway efficiency is better, thanks to the car’s aerodynamic profile and the eight-speed automatic transmission’s ability to settle into a fuel-sipping overdrive gear at cruising speeds. The long-distance touring capability the 840i Gran Coupe is known for is where that 29 MPG figure becomes relevant.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 BMW 840i Gran Coupe at $2,400. This calculation is based on driving 15,000 miles per year, using the EPA’s combined MPG rating, and factoring in the national average price of premium gasoline, which this car requires. While individual fuel costs will vary depending on driving habits, location, and fuel prices, this figure provides a benchmark for prospective owners. The $2,400 figure is a reminder that driving a luxury performance car comes with expenses above the purchase price.

Real-world expectations

While the EPA provides a standardized estimate, real-world MPG can change noticeably. Aggressive driving, frequent short trips, and prolonged idling can all significantly reduce fuel economy. However, gentle acceleration, consistent highway speeds, and proactive maintenance can help drivers get closer to the EPA estimates. Considering the 840i Gran Coupe’s performance capabilities, it’s easy to dip below the EPA’s 24 MPG combined rating if you regularly push the car. Those with a lighter foot and a focus on efficiency can likely match or even slightly exceed the EPA highway figure on long road trips. It’s important to compare this information with all Bmw fuel economy data to get a better understanding of how the 840i Gran Coupe compares to other BMW models.

How it compares

The 2020 BMW 840i Gran Coupe occupies a unique space in the market. The Audi A7, with its standard Quattro all-wheel drive and turbocharged V6, manages around 22 MPG combined. The Mercedes-Benz CLS 450 achieves roughly 25 MPG combined with its mild-hybrid inline-six. The Porsche Panamera posts around 21 MPG combined in its base rear-wheel-drive configuration but offers a range of powertrains, including hybrids. The difference in fuel economy isn’t typically the deciding factor for buyers in this segment. Instead, brand preference, styling, performance characteristics, and interior appointments tend to weigh more heavily in the decision-making process. Make sure to confirm specific 840I MPG across all years, as changes do occur. The 840i Gran Coupe’s fuel consumption is quite reasonable given what it offers.

Tips to maximize efficiency

Anticipate traffic flow and maintain a steady speed whenever possible. The 840i Gran Coupe’s smooth power delivery allows for effortless cruising with minimal throttle input. Avoid abrupt acceleration and hard braking, as these actions waste fuel and put unnecessary stress on the powertrain.

Ensure that your tires are properly inflated to the recommended pressure. Underinflated tires increase rolling resistance, which reduces fuel efficiency. Check your tire pressure regularly, especially during changes in temperature.

Reduce unnecessary weight in the vehicle. Extra cargo adds to the overall load, forcing the engine to work harder and consume more fuel. Remove items from the trunk and cabin that aren’t essential for your journey.

Use the BMW’s driving modes. The “Eco Pro” mode optimizes various vehicle settings, such as throttle response and shift points, to prioritize fuel efficiency. Using this mode can help you achieve better MPG, especially during city driving.
