19 MPG combined is what you get with the 2025 BMW X6 M60i xDrive. This isn’t a vehicle purchased for saving money on gas; it’s acquired for its coupe-like style, surprisingly practical SUV design, and thrilling performance from a twin-turbocharged V8. Buyers interested in this X6 variant aren’t mainly worried about fuel costs; they want the image and driving experience that makes it different from other SUVs, and the fuel consumption is a known consequence.

City and highway performance

The EPA estimates the X6 M60i will get 17 MPG in the city and 22 MPG on the highway. The city number reflects the stop-and-go driving where the engine is more often idling at lower speeds, inefficiencies that are made worse by the weight and complexity of the powertrain. The highway number, while still not great, shows that the engine can work more efficiently at consistent speeds with less acceleration and deceleration. These numbers are important to consider based on how you drive; city drivers will probably see numbers closer to 17 MPG, while those who drive mostly on the highway could get close to the 22 MPG estimate. These numbers are as expected for a powerful, performance-oriented SUV.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2025 BMW X6 M60i xDrive will be $3,050. This number is based on driving 15,000 miles per year and using national average fuel prices. Remember that this is an estimate. Your actual fuel costs will change based on your driving habits, the type of fuel you buy, and changes in gas prices. Regular spirited driving, which is common with a vehicle that has this much power, will probably make that number go up. But for the target buyer, the thrill is worth the fill.

Real-world expectations

While the EPA provides a standard testing method, real-world fuel economy can be very different. Hard acceleration, often using the X6 M60i’s sport modes, and carrying heavy loads will all lower fuel efficiency. On the other hand, gentle acceleration, consistent speeds, and using the vehicle’s Eco Pro mode can potentially improve fuel economy closer to the EPA estimates. Knowing your own driving style and typical usage is key to having realistic expectations for fuel consumption. The X6 M60i’s onboard computer tracks fuel consumption, giving a more accurate picture of your individual MPG.

How it compares

Other performance SUVs have different levels of fuel consumption. The Porsche Cayenne Turbo Coupe, which also emphasizes performance and style, gets similar fuel economy, often around 17 MPG combined. The Mercedes-AMG GLE 63 S Coupe, another rival, also lands in a similar range with EPA estimates around 16 MPG combined. The Land Rover Range Rover Sport P530, while offering off-road capability the X6 doesn’t have, burns fuel at a rate close to 18 MPG combined. The Audi SQ8, with a slightly less powerful but still impressive V8, gets around 18 MPG combined. These comparisons show that the X6 M60i’s fuel economy is about what you’d expect for its class and performance level, reinforcing that the buyer cares more about overall experience than efficiency.

Tips to maximize efficiency

Use the X6 M60i’s Eco Pro mode when you can. This mode changes engine response, transmission shift points, and climate control settings to prioritize less gas. Horsepower will be slightly reduced, but it’s a good trade-off for everyday driving when you don’t need maximum performance.

Avoid hard acceleration and hard braking. The X6 M60i’s powerful engine can make drivers want to accelerate quickly, but this really hurts fuel consumption. Smooth, gradual acceleration and predicting traffic will help save fuel. Maintaining a steady speed on the highway is also important; avoid quick starts and stops.

Make sure your tires are properly inflated. Underinflated tires increase rolling resistance, which hurts fuel economy. Check your tire pressure regularly and keep the pressure at the recommended level found on the tire placard on the driver’s side doorjamb. Use premium fuel as recommended by BMW. The high-performance engine in the X6 M60i is designed to run best on premium fuel. Using lower-octane fuel can reduce performance and potentially damage the engine over time. Check your owner’s manual for specific fuel recommendations. For more on the X6 MPG across all years, search this site.

Don’t let the engine idle. Letting the engine idle for a long time wastes fuel. If you’re stopped for more than a minute, turn off the engine. Modern engines are designed to restart quickly and efficiently, making this an easy way to save fuel, especially in cities.
