17 MPG combined is a hard pill to swallow in 2017, but the BMW X6 xDrive50i isn’t for the fuel-conscious. This is a statement vehicle, a coupe-like SUV with rakish lines and a potent V8 that send a clear message: Performance and presence trump practicality. For buyers drawn to its unique style and effortless power, fuel economy is often a secondary consideration, a necessary compromise for the driving experience it delivers.

City and highway performance

The EPA estimates the X6 xDrive50i at 15 MPG in the city and 21 MPG on the highway. The city figure reflects the engine’s thirst in stop-and-go traffic, further driven by the vehicle’s weight. The highway number is more palatable, but even then aggressive driving will quickly lower that number. The eight-speed automatic transmission does its best to optimize efficiency, but a large displacement V8 will always demand its share of fuel.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2017 BMW X6 xDrive50i is $3,400. This estimate is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, using national average fuel prices. Keep in mind that premium fuel is recommended, which significantly increases the cost per gallon. This annual expenditure should factor into the ownership costs for prospective buyers, especially considering fluctuating fuel prices.

Real-world expectations

While the EPA estimates provide a baseline, real-world MPG can vary based on driving habits and conditions. You can expect to see numbers lower than the EPA figures, especially if you frequently use the engine’s considerable power or drive primarily in urban environments. Those who prioritize smooth acceleration and consistent highway speeds are more likely to approach the EPA estimates. The responsiveness of the 4.4L engine, and the enjoyment it provides, often encourages a heavier foot than is ideal for fuel efficiency.

How it compares

The X6 xDrive50i exists in a niche segment. The Porsche Cayenne S, with its 3.6L twin-turbo V6, manages a slightly better 19 MPG combined, appealing to those seeking an even sportier driving experience. The Mercedes-Benz GLE 43 AMG Coupe achieves a similar 17 MPG combined figure but offers AMG-enhanced performance. Across all Bmw fuel economy data, the X6 50i sits near the bottom, trading frugality for outright grunt. For those less concerned by the sloping roofline, the more conventional BMW X5 xDrive50i delivers similar performance and economy. It’s important to compare X6 MPG across all years to see how this model year stacks up relative to others.

Tips to maximize efficiency

Resist the urge to constantly exploit the V8’s prodigious power. Smooth acceleration and avoiding hard braking will improve gas mileage. This engine responds well to gentle inputs, you’ll be surprised how much difference a relaxed driving style can make. Remember, every time you bury the throttle, you’re impacting your fuel consumption.

Ensure your tires are properly inflated. Under-inflated tires increase rolling resistance, forcing the engine to work harder and burn more fuel. Check your tire pressure regularly and maintain the recommended level specified on the driver’s side door jamb. This simple step can improve fuel efficiency.

Use the ECO PRO driving mode whenever possible. This mode adjusts the engine mapping, throttle response, and transmission shift points to prioritize fuel efficiency. While it does slightly reduce performance feel, it’s ideal for highway cruising or stop-and-go traffic where outright power isn’t necessary.

Reduce unnecessary weight in the vehicle. Extra cargo adds to the overall weight the engine must move, impacting fuel economy. Remove any items you don’t need to carry to minimize the burden on the engine. A lighter load translates into improved efficiency.
