24 MPG combined. The 2023 BMW 840i xDrive Gran Coupe delivers this fuel economy, which may surprise some, but is acceptable for drivers who value style, performance, and all-weather confidence more than ultimate efficiency. This isn’t a Prius competitor. It’s a four-door coupe with striking sheet metal, a smooth inline-six engine, and all-wheel drive. Buyers likely prioritize the thrill of driving it over saving on premium fuel costs.

City and highway performance

The EPA says the 840i xDrive Gran Coupe gets 21 MPG in the city and 29 MPG on the highway. City driving involves frequent stops, and the car’s weight and responsive engine affect fuel consumption. The highway number suggests the 3.0-liter engine is relatively efficient when cruising at consistent speeds. However, drivers who accelerate quickly or frequently use the engine’s power will probably see lower highway MPG. If you are curious about 840I MPG across all years, explore that data.

Annual fuel cost

The EPA estimates the 2023 BMW 840i xDrive Gran Coupe’s annual fuel cost at $2,400. This is based on driving 15,000 miles per year and using the national average fuel price at the time of calculation. Your actual fuel costs will vary depending on your driving habits, local fuel prices, and driving conditions. Someone who drives mainly in the city and accelerates rapidly will likely exceed this estimate, while someone who drives mostly on the highway with a light foot might spend less. $2,400 is a benchmark based on standardized testing data.

Real-world expectations

While the EPA provides a standard, real-world fuel economy often differs. Factors such as traffic, driving style, tire pressure, and weather can all affect MPG. Owners who accelerate smoothly, follow speed limits, and maintain their vehicles well can generally expect MPG close to the EPA estimates.

However, those who frequently merge aggressively, enjoy spirited driving, or neglect maintenance can expect lower MPG.

How it compares

The 840i xDrive Gran Coupe is in a competitive class. The Audi A7, with its similar design and powerful engine, gets around 22 MPG combined with its 3.0-liter V6. The Mercedes-Benz CLS 450, another four-door coupe, also gets about 23 MPG combined. The BMW’s fuel economy is typical for its class, and none of these stylish and powerful vehicles are especially fuel efficient. The 840i offers similar performance and luxury to its competitors with comparable fuel consumption. Those who are interested in all Bmw fuel economy data should explore the wealth of information available.

Tips to maximize efficiency

Use the BMW’s driving modes. “Eco Pro” mode changes the throttle response and shift patterns to prioritize fuel efficiency. It might slightly reduce acceleration, but it can save gas on longer trips.

Keep your tires inflated to the recommended pressure, which is on a sticker inside the driver’s side doorjamb. Underinflated tires increase rolling resistance, making the engine work harder and use more fuel. Checking tire pressure is a simple way to improve fuel economy.

Remove unnecessary weight from the vehicle. Extra cargo in the trunk increases the weight and reduces fuel efficiency. Remove items you don’t need for daily commutes or trips, like golf clubs or tools.

Avoid accelerating quickly and braking hard. Smooth acceleration and gentle braking improve fuel economy and make driving safer and more comfortable. Anticipate traffic and maintain a consistent speed to reduce wasted energy.

Consider using cruise control on the highway. Maintaining a constant speed reduces speed changes and helps optimize fuel efficiency. Cruise control works well on long trips with minimal elevation or traffic changes, letting the engine operate efficiently.
