17 MPG combined is what you’ll likely get with a 2017 BMW X5 xDrive50i. This X5 isn’t about sensible commuting; it’s about strong V8 power, a luxurious interior, and the prestige of the BMW badge. The fuel economy is simply the price you pay for that experience. The typical buyer probably isn’t prioritizing fuel efficiency above all else, but understanding the numbers is still important.

City and highway performance

The EPA estimates for the 2017 X5 xDrive50i are 15 MPG in the city and 21 MPG on the highway. The city figure reflects stop-and-go traffic, where the 4.4-liter twin-turbocharged V8 constantly accelerates a vehicle weighing over 5,000 pounds. The highway number is more reasonable, but still reflects the engine’s displacement and power output. This isn’t a hybrid designed for long, efficient cruises. Instead, anticipate frequent stops at the pump, especially if you mostly drive in the city. The eight-speed automatic transmission optimizes fuel consumption as much as it can, but it can only do so much when paired with such a potent engine.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 BMW X5 xDrive50i at $3,400. This figure assumes 15,000 miles of driving per year, with 55% city driving and 45% highway driving, using the national average fuel price for premium gasoline, which this X5 requires. Your actual fuel costs will change based on your individual driving habits, the specific conditions in your area, and changes in gasoline prices. However, the $3,400 provides a standardized benchmark that helps in comparing the running costs of different vehicles.

Real-world expectations

While the EPA provides a useful baseline, real-world fuel economy often differs. X5 xDrive50i owners report numbers close to the EPA figures, but aggressive driving can easily lower the average. Enjoying the V8’s performance, the exhilarating acceleration and the confident passing power, inherently reduces fuel efficiency. On the other hand, careful drivers who prioritize smooth acceleration and consistent speeds might see slightly better results, especially on longer highway trips. Consider these estimates a guide, not a guarantee, and consider your own driving style when budgeting for fuel costs. You can learn about all Bmw fuel economy data to compare models.

How it compares

Compared to its rivals, the 2017 BMW X5 xDrive50i is less fuel-efficient than models with smaller engines or hybrid powertrains, as you might expect. For example, the Volvo XC90 T6 AWD offers similar luxury and space, but gets around 22 MPG combined. The Audi Q7 3.0T (supercharged V6 gas) achieves a similar 21 MPG combined. Even the Range Rover Sport with its supercharged V6 gets marginally better mileage. The X5 xDrive40e, the plug-in hybrid variant from the same model year, significantly improves fuel economy. Its performance characteristics and driving experience are quite different. Choosing the X5 xDrive50i means prioritizing V8 performance over fuel efficiency, recognizing that the fuel bill will be higher than many competitors. Compare to X5 MPG across all years to gain more insight.

Tips to maximize efficiency

Fuel efficiency isn’t the X5 xDrive50i’s strength, but some strategies can help to minimize consumption. First, avoid aggressive acceleration. The twin-turbo V8 is responsive, but easing into the throttle rather than flooring it will make a noticeable difference over time.

Use the X5’s Eco Pro driving mode. This mode adjusts the throttle response, transmission shift points, and climate control settings to prioritize fuel efficiency. It might slightly dampen the driving experience, but it can lead to real improvements in MPG, especially in city driving.

Make sure that your tires are properly inflated. Underinflated tires create more rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressures regularly and maintain them at the recommended levels, which is on a sticker placed inside the driver’s door jamb.

Reduce unnecessary weight. Carrying extra cargo in the vehicle adds to its overall load. It forces the engine to expend more energy. Remove any unnecessary items in the trunk or passenger area to reduce weight and improve fuel economy.
