20 MPG combined isn’t going to win any awards for lower fuel costs, but for the 2019 BMW M550i xDrive, it’s the trade-off for performance. This isn’t a car bought by those prioritizing frugality. It’s for drivers who want both strong performance and luxury, and they’re willing to pay more at the pump. This M550i has a 4.4L 8-cylinder engine and an automatic (S8) transmission, creating an exhilarating and refined driving experience. Consider the 20 MPG figure a tax on the readily available power.
City and highway performance
The M550i xDrive gets an EPA-estimated 18 MPG in the city and 25 MPG on the highway. In stop-and-go traffic, the V8 engine uses more gasoline, resulting in the lower city MPG. The highway number is better, but the car’s performance can still reduce it. While cruising at a steady 75 MPH might get you close to 25 MPG, using the accelerator will quickly diminish that figure. The xDrive all-wheel-drive system enhances grip and stability, but it adds weight and complexity, slightly impacting fuel efficiency compared to a rear-wheel-drive car.
Annual fuel cost
The EPA estimates the annual fuel cost for the 2019 BMW M550i xDrive at $2,900. This is based on driving 15,000 miles per year and using national average fuel prices. Your costs will vary depending on driving habits, location, and fuel prices. If you drive more in city traffic or drive hard, you’ll likely exceed this estimate. However, for some, the pleasure of driving an M550i is worth the cost.
Real-world expectations
The EPA estimates are a starting point, but actual fuel economy varies. Drivers of the 2019 M550i xDrive report different MPG figures depending on how and where they drive. Some who focus on efficiency and drive mostly on the highway have reported exceeding the EPA’s 25 MPG estimate. Others, who often push the car’s limits, have seen their fuel economy drop below the 18 MPG city mark. The most accurate information will come from your own test drives and monitoring your fuel consumption over time to see if this car will work for you based on your personal driving habits.
How it compares
The 2019 BMW M550i xDrive’s fuel economy is typical for its class. The Audi S6, with its smaller engine, gets a slightly better 22 MPG combined, and the Mercedes-AMG E53 sedan gets around 21 MPG combined. When comparing these options, consider the performance of each vehicle. The M550i provides a balance of power and handling that may make its fuel consumption acceptable for some drivers.

Tips to maximize efficiency
The M550i isn’t designed for maximum MPG, but you can improve its fuel economy. Accelerate gently and anticipate traffic flow to reduce gas consumption, especially in the city.
Choose the right driving mode. “Eco Pro” mode adjusts the engine and transmission for maximum efficiency. It might make the throttle less responsive, but it can reduce fuel consumption during commutes.
Keep your tires properly inflated. Under-inflated tires increase rolling resistance, making the engine work harder and use more fuel. Check your tire pressures and inflate them to the recommended levels.
Avoid idling. Letting the engine idle wastes fuel. If you’re stopped for more than a minute, turn off the engine and restart it.
Regular maintenance is important. Keep your engine properly tuned and perform all recommended maintenance on schedule. A well-maintained engine runs more efficiently, leading to better fuel economy. For details about this model, research M550I MPG across all years.
