20 MPG combined isn’t going to win any awards, but for the 2022 BMW M850i xDrive Coupe, it’s the price to pay for effortless power, stunning design, and grand touring capability. This isn’t a car purchased by those focused on minimizing their carbon footprint; it’s for those who value performance and style and are willing to accept the fuel consumption that comes with a potent twin-turbo V8.
City and highway performance
The EPA estimates 17 MPG in the city and 25 MPG on the highway for the 2022 M850i xDrive Coupe. The city fuel economy reflects the engine’s thirst when navigating stop-and-go traffic, highlighting that the 4.4L V8 needs a healthy dose of fuel to deliver its instant responsiveness. On the open road, however, the M850i reveals its grand touring character.
The 25 MPG highway rating demonstrates that when cruising at consistent speeds, the engine management system can optimize fuel consumption considerably, allowing for comfortable long-distance journeys.
Annual fuel cost
The EPA estimates an annual fuel cost of $2,900 for the 2022 BMW M850i xDrive Coupe. This figure is based on driving 15,000 miles per year and using national average fuel prices. Keep in mind that this number can fluctuate depending on individual driving habits and regional fuel costs. Drivers with a heavier foot or those who predominantly drive in congested city environments can expect to exceed this estimate. To compare this to all Bmw fuel economy data, review all models available.
Real-world expectations
While the EPA provides a standardized measurement, real-world fuel economy often varies. M850i drivers are known for enjoying the car’s performance, which naturally impacts fuel consumption. Aggressive acceleration and frequent use of the Sport or Sport+ driving modes will undoubtedly lower the MPG figures. However, those who prioritize smooth, consistent driving and use the Eco Pro mode more frequently may find themselves closer to, or even slightly above, the EPA estimates for the M850I MPG across all years.
How it compares
Compared to its rivals, the 2022 M850i xDrive Coupe’s fuel economy is within the expected range for a high-performance grand tourer. The Mercedes-AMG S63 Coupe, for example, achieves around 17 MPG combined, trading blows with the M850i with nearly identical gas mileage.
Further from Germany, the Lexus LC 500 manages slightly better at 19 MPG city and 28 MPG highway due to its naturally aspirated engine, but it offers a noticeably different driving experience focused on smoothness rather than outright power found in the BMW. The Porsche 911 Carrera 4S, another performance benchmark, attains an estimated 20 MPG combined, like the BMW, but with a smaller, turbocharged engine and a very different driving feel.
Tips to maximize efficiency
Use the Eco Pro driving mode whenever possible, especially during highway cruising or when encountering stop-and-go traffic. This mode optimizes engine settings, throttle response, and transmission behavior to prioritize fuel efficiency. It won’t turn the M850i into a hybrid, but it can noticeably reduce fuel consumption during everyday driving.
Ensure your tires are properly inflated to the recommended pressure, which is listed on the sticker inside the driver’s side doorjamb. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Keeping tires properly inflated is as important as regular maintenance.
Anticipate traffic flow and avoid unnecessary hard acceleration and braking. Smooth, consistent driving not only improves fuel economy but also enhances the luxurious grand touring experience that the M850i is designed to deliver. Let the car’s advanced driver assistance systems help maintain a consistent pace and appropriate following distance.
Minimize idling time. If you’re stopped for more than a minute, especially with the air conditioning running, turn off the engine. Modern engines are designed to restart quickly, and prolonged idling wastes fuel unnecessarily.
Keep the car’s weight down. Remove any unnecessary items from the trunk and passenger compartment. Extra weight puts added strain on the engine, leading to increased fuel consumption. Streamlining the vehicle even further makes a difference on gas mileage in the long run.
