20 MPG combined. That’s the fuel economy for the 2017 BMW X5 xDrive35i. It doesn’t win any awards for being especially fuel efficient. But for buyers looking for a luxury SUV with a potent inline-six engine, all-wheel drive, and the BMW driving experience, fuel economy is often less important than performance and prestige. A buyer choosing this X5 likely wants spirited driving and a luxurious cabin more than squeezing every last mile from a gallon of premium fuel.

City and highway performance

The EPA numbers are 18 MPG in the city and 24 MPG on the highway. The city figure reflects the stop-and-go nature of urban driving, where the X5’s 3.0-liter turbocharged engine works harder to move the vehicle’s weight from a standstill. The highway MPG, while better, still isn’t great. The X5’s all-wheel-drive system adds weight and driveline friction, and the vehicle’s shape isn’t designed for maximum efficiency at cruising speeds. Careful use of the accelerator on long road trips will help you achieve numbers closer to the EPA estimate, but quick acceleration will quickly reduce your fuel savings.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 BMW X5 xDrive35i at $2,900. This is based on driving 15,000 miles per year, with a mix of city and highway driving, and using national average fuel prices for premium gasoline (which the BMW requires). This is an estimate, and your actual fuel costs may vary depending on your driving, the roads you typically drive on, and gas prices in your area. Consider $2,900 to be a realistic benchmark when budgeting for the costs of owning this X5.

Real-world expectations

While the EPA provides a standard estimate, real-world fuel economy for the 2017 X5 xDrive35i can change quite a bit. Drivers in congested urban areas, consistently making short trips, may see numbers below 18 MPG. On the other hand, those who primarily drive on the highway, maintaining consistent speeds, may achieve numbers closer to, or even slightly above, the 24 MPG estimate. Expect a range of 17-25 MPG, depending on driving style and conditions. Check X5 MPG across all years to see a range of reported fuel economy.

How it compares

The fuel economy of the 2017 X5 xDrive35i is about in the middle of its class regarding fuel efficiency. For comparison, the 2017 Acura MDX SH-AWD achieves 19 MPG city / 27 MPG highway, making it a slightly more efficient choice, trading some driving dynamics for lower running costs. The Audi Q7 2.0T quattro boasts 20 MPG city and 25 MPG highway, offering similar performance with a slightly better efficiency in the city. A 2017 Mercedes-Benz GLE 350 4MATIC is rated at 18 MPG city / 22 MPG highway, which is a less efficient option. The buyer considering these alternatives must weigh fuel economy against other factors, such as handling, interior quality, and brand.

Tips to maximize efficiency

Gentle acceleration helps you save fuel in the X5. The turbocharged engine is responsive, but heavy use of the accelerator will quickly empty the fuel tank. Anticipate traffic flow and avoid quick starts and stops to reduce fuel use during your commute.

Maintaining proper tire inflation, as specified on the door jamb sticker, reduces rolling resistance. Under-inflated tires require more energy to move the vehicle, decreasing fuel efficiency. Regularly check your tire pressure, especially when the temperature changes.

Using the X5’s Eco Pro mode can help you save fuel. This driving mode changes the throttle response and adjusts the transmission shift points to prioritize efficiency. It also helps the driver to drive more efficiently.

Use accessories like air conditioning and heated seats only when needed, as they place additional demands on the engine. Reducing these loads can have a positive impact on your MPG, however small. Opening the windows is an option when the weather allows.

Regular maintenance is important for good fuel economy. A poorly maintained engine will burn fuel less efficiently. Keep up with scheduled oil changes, air filter replacement, and other recommended services to ensure your X5 operates as it should. Check all Bmw fuel economy data to see the impact of maintenance on your preferred driving experience.
