24 MPG combined is what you can expect when experiencing the 2024 BMW 840i Coupe’s blend of athleticism and grand touring comfort. This isn’t a hybrid trying to squeeze every last mile from each gallon; it shows what the priorities are. The 840i buyer appreciates performance, luxury, and exclusivity, and they’re willing to accept respectable, if not groundbreaking, fuel economy as part of the deal. They understand that the smooth power delivery of the turbocharged inline-six and the optimized chassis dynamics don’t come without a cost.

City and highway performance

The EPA estimates the 840i Coupe at 21 MPG in the city and 29 MPG on the highway. The city figure reflects the stop-and-go reality of urban driving where the engine spends a significant amount of time idling or accelerating from a standstill. The highway number shows the engine at its most efficient, cruising at a steady speed. The well-calibrated eight-speed automatic transmission (S8) also helps optimize fuel economy by keeping the engine in its most efficient RPM range.

Annual fuel cost

The EPA calculates that the annual fuel cost for the 2024 BMW 840i Coupe will be approximately $2,400. This figure is based on driving 15,000 miles per year, with an assumed fuel price reflecting the national average for premium gasoline. Individual fuel costs will vary depending on driving habits, local fuel prices, and the proportion of city versus highway driving.

Real-world expectations

While the EPA estimates provide a useful baseline, real-world fuel economy often differs. Driving with enthusiasm, frequent short trips, and using Sport mode will all negatively impact fuel efficiency. However, drivers who prioritize smooth acceleration, anticipate traffic flow, and use the Eco Pro driving mode can likely achieve figures closer to the EPA estimates, if not slightly better, during highway driving. Remember to consult 840I MPG across all years to understand long term trends.

How it compares

Compared to its competitors, the 840i’s fuel economy is competitive within its segment. The Mercedes-Benz CLS 450 4MATIC, while boasting similar horsepower and luxury, achieves a slightly lower combined MPG of 25 MPG. The Lexus RC 350 F Sport, with its V6 engine, delivers a comparable 23 MPG combined, but lacks the BMW’s outright performance and driving experience. Of course, stepping down to a smaller coupe like the Audi A5 achieves noticeably better fuel economy (28 MPG combined for the 45 TFSI quattro), but that car is for a different buyer seeking efficiency above all else. The 840i Coupe buyer accepts a degree of fuel consumption in exchange for the car’s unique blend of performance, luxury, and style.

Tips to maximize efficiency

Using the Eco Pro driving mode can significantly improve fuel economy. This mode adjusts throttle response, shift points, and climate control settings to prioritize less gas. While it might slightly reduce performance, it’s good for relaxed cruising and maximizing mileage on long trips.

Smooth and gradual acceleration is key to saving fuel. Avoid sudden bursts of speed, as these consume significantly more gasoline. Anticipate traffic flow and maintain a consistent speed whenever possible.

Proper tire inflation is a simple yet effective way to boost fuel economy. Check your tire pressure regularly and ensure it matches the recommended settings listed on the driver’s side doorjamb. Under-inflated tires increase rolling resistance, which can negatively impact fuel efficiency.

Minimize idling. If you’re stopped for more than a minute, turn off the engine. Modern engines are designed restart quickly and efficiently, and prolonged idling wastes fuel unnecessarily.
