The 2016 BMW X6 sDrive35i gets 21 MPG combined. It’s what you get for the X6’s unique coupe-like roof on a mid-size SUV, plus BMW’s driving experience. X6 sDrive35i buyers likely aren’t focused on fuel efficiency, they’re purchasing a statement. They want the high driving position, optional xDrive all-wheel drive, and luxury, but in a package that’s different from other SUVs.

City and highway performance

The EPA estimates the X6 sDrive35i at 18 MPG in the city and 25 MPG on the highway. The lower city MPG reflects stop-and-go traffic where the 3.0L turbocharged inline-six engine works harder due to the X6’s weight. The highway MPG is better because the engine’s torque and the eight-speed automatic transmission allow cruising at lower RPMs. But, aggressive driving and frequent lane changes will reduce those highway MPG gains rapidly.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2016 BMW X6 sDrive35i at $2,750. This is based on 15,000 miles per year, with a mix of city and highway driving like the EPA’s tests. This also uses national average fuel prices from when the calculations were made. Actual fuel costs will vary based on driving, local fuel prices, and the type of fuel (premium is recommended). While $2,750 may seem high, X6 buyers likely consider this cost given the car’s luxury and performance.

Real-world expectations

The EPA provides a standard, but real-world MPG for the X6 sDrive35i will vary. Drivers who accelerate quickly or drive in city traffic can expect numbers closer to the city MPG, or even lower. On the other hand, drivers who accelerate smoothly, use cruise control on the highway, and avoid idling may get numbers close to, or even above, the EPA highway MPG. Temperature also affects MPG. Cold weather usually decreases MPG in any car.

How it compares

The 2016 BMW X6 sDrive35i’s fuel economy is what it is compared to its rivals. A Mercedes-Benz GLE Coupe with similar equipment offers comparable MPG, often within 1 MPG of the X6 in combined ratings. A Porsche Cayenne Coupe has more powerful engine options, but less fuel economy, with some models below 20 MPG combined. However, if a buyer doesn’t need the coupe roof, a regular SUV like the BMW X5 offers slightly better fuel economy. The X5 sDrive35i often gets 1-2 MPG higher in combined ratings. Smart shoppers can review X6 MPG across all years when deciding to purchase.

Tips to Maximize Efficiency

Drive smoothly. The X6’s inline-six engine responds quickly, but avoid fast acceleration and hard braking. Smooth acceleration and watching traffic can boost fuel economy.

Keep your tires inflated. Under-inflated tires increase rolling resistance. Check your tire pressure often and inflate them to the pressure on the doorjamb sticker.

Avoid idling. Idling for long periods wastes fuel. If you’ll be stopped for more than a minute, turn off the engine.

Use cruise control on the highway. Holding a steady speed on the highway saves fuel compared to changing your speed. Use cruise control when possible.

Follow the maintenance schedule. Regular maintenance maintains engine efficiency. A well-maintained engine uses less fuel and runs best. For all Bmw fuel economy data make sure your vehicle is in top mechanical condition.
