The 2019 BMW X6 xDrive35i 3.0L 6-cyl gets 20 MPG combined. This SUV isn’t ideal for those on a budget or prioritizing fuel efficiency. X6 buyers want coupe styling, elevated ride height, and the BMW brand, and accept middling fuel economy. They are paying for a statement, so efficiency is not the main concern.

City and highway performance

EPA estimates are 18 MPG in the city and 24 MPG on the highway, reflecting the X6’s compromises. The turbocharged 3.0-liter inline-six provides plenty of power, but it has to move over 4,600 pounds. Stop-and-go traffic lowers fuel economy, while highway cruising improves it because the eight-speed automatic transmission shifts to a more efficient gear. Achieving 24 MPG on the highway needs a disciplined foot and flat terrain. Driving aggressively will reduce any potential savings.

Annual fuel cost

The EPA says the annual fuel cost for the 2019 BMW X6 xDrive35i is $2,900. This estimate assumes 15,000 miles per year and national average fuel prices. Premium fuel is recommended for optimal performance, increasing running costs compared to vehicles using regular unleaded. The $2,900 is a baseline, as driving habits and local fuel prices affect your actual expenses. Expect to spend more if you drive fast or live where fuel is costly.

Real-world expectations

EPA numbers offer a standard, but real-world MPG often varies. Traffic, driving style, and weather all matter. Expect figures below EPA estimates, especially in city driving. Many owners realistically get a combined average in the high teens. Highway trips, driven conservatively, might reach the EPA’s 24 MPG, but it takes effort to consistently get that. Use the trip computer to monitor fuel consumption and see how driving habits affect economy.

How it compares

The X6’s fuel economy is worse than some competitors. The Acura MDX SH-AWD gets a combined 22 MPG and is more practical. Even BMW’s X5 xDrive40i, a more typical SUV, gets a slightly better 22 MPG combined. The Mercedes-Benz GLE 450 4MATIC, another rival, gets 21 combined MPG. While seemingly small, this difference adds up. X6 shoppers often prioritize the vehicle’s styling over efficiency, making these MPG differences less important to their decision.

Tips to maximize efficiency

Avoid accelerating and braking hard. The turbocharged engine responds quickly, but rapid speed increases use fuel fast. Drive gently and gradually to keep momentum and reduce wasted fuel.

Check your tire pressure regularly. Underinflated tires increase rolling resistance, making the engine work harder and reducing fuel economy. Check tires monthly and inflate them to the pressure on the driver’s side door jamb.

Minimize idling. Modern engines are efficient when running, but idling uses fuel without traveling any distance. Turn off the engine if you’ll stop for more than a minute or two to save fuel.

Use cruise control on the highway. Cruise control keeps a steady speed, preventing throttle fluctuations that waste fuel. This helps on long trips where you can maintain a consistent speed.

Reduce the vehicle’s weight. Extra weight increases fuel consumption. Remove unnecessary items from your vehicle, like heavy cargo or unused roof racks, to improve efficiency.
