20 MPG combined isn’t going to win any fuel economy awards, but then again, the 2017 BMW X6 xDrive35i isn’t really trying to. This is a statement vehicle, a coupe-styled SUV that prioritizes aggressive looks and a sporty driving experience over outright efficiency. Buyers drawn to the X6 are purchasing a feeling, an image, and a unique presence on the road ,factors that often outweigh concerns about filling up at the pump.

City and highway performance

The EPA estimates the 2017 X6 xDrive35i at 18 MPG in the city and 24 MPG on the highway. That spread reflects the car’s dual nature. In urban environments, stop-and-go traffic forces the engine to work harder, diminishing efficiency. The X6’s weight and all-wheel-drive system further contribute to lower city numbers. On the open road, however, the turbocharged 3.0L inline-six engine, paired with its smooth eight-speed automatic transmission, settles into a more efficient stride. Highway driving allows the engine to operate within its sweet spot, where power delivery and fuel consumption are better balanced, and the aerodynamics of the X6, as unusual as they are for an SUV, help it maintain a decent MPG figure.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 BMW X6 xDrive35i at $2,900. This figure is based on driving 15,000 miles per year, with a 55/45 split between city and highway driving, and using the national average fuel price. Keep in mind that premium fuel is recommended for this engine to achieve optimal performance and fuel economy. Therefore, your actual fuel costs may vary depending on your driving habits, location, and current fuel prices. Expect to spend a significant amount on fuel compared to more efficient SUVs.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy often deviates based on driving style, traffic conditions, and even tire pressure. Aggressive acceleration, frequent hard braking, and prolonged idling will all negatively impact the X6’s MPG. Owners who consistently drive in heavy traffic or prioritize spirited driving should expect numbers closer to the lower end of the EPA range, possibly even below 18 MPG combined. Conversely, drivers who adopt a smoother, more deliberate style and spend more time on the highway might achieve slightly better results. Always check X6 MPG across all years to see results from other drivers.

How it compares

Compared to its core competitors, the 2017 BMW X6 xDrive35i’s fuel economy lands squarely in the middle of the pack. The Mercedes-Benz GLE Coupe, particularly the GLE 43 AMG Coupe (around 18 MPG combined), prioritizes performance even further, resulting in lower fuel economy. The Porsche Cayenne Coupe, in its base configuration, offers comparable MPG figures. Meanwhile, a more traditionally-shaped SUV like the Acura MDX, while not boasting the X6’s sporty image, manages around 22 MPG combined, a considerable advantage. Consider these differences when evaluating all Bmw fuel economy data.

Tips to maximize efficiency

The turbocharged 3.0L inline-six in the X6 is responsive, but also sensitive to throttle input. Resist the urge to accelerate aggressively from every stop. Gradual acceleration allows the engine to operate more efficiently, especially in city driving, helping you conserve fuel.

Regularly check tire pressure. Underinflated tires increase rolling resistance, forcing the engine to work harder and consuming more fuel. Maintaining the recommended tire pressure, typically found on a sticker inside the driver’s side doorjamb, optimizes fuel efficiency and also improves handling and tire wear.

Use cruise control on highway drives. Maintaining a consistent speed minimizes unnecessary acceleration and deceleration, resulting in improved fuel economy. Modern adaptive cruise control systems, if equipped, can further enhance efficiency by automatically adjusting speed to maintain a safe following distance.

Avoid unnecessary idling. If you’re stopped for more than a minute or two, turn off the engine. Idling consumes fuel without actually moving the vehicle, especially during periods of extended waiting. Restarting the engine consumes little fuel and is more efficient than prolonged idling.

Plan your routes strategically. Avoid congested areas and known traffic bottlenecks whenever possible. Choosing routes with fewer stops and starts, even if they are slightly longer, can lead to significant fuel savings, particularly in urban environments.
