15 MPG combined is not a typo when discussing the 2020 BMW X6 M Competition; it’s a cost of doing business. This vehicle is for those who demand outrageous performance, head-turning style, and a commanding presence, and who are prepared to pay for it at the pump. Buyers aren’t cross-shopping this with a Prius; they’re likely considering other high-performance SUVs and are prioritizing adrenaline over efficiency.

City and highway performance

The EPA estimates of 13 MPG in the city and 18 MPG on the highway reflect the X6 M Competition’s nature. The city figure suffers because of the vehicle’s weight and the frequent stop-and-go driving, forcing the 4.4L twin-turbo V8 to work hard from a standstill. The highway figure, while better, is still impacted by the vehicle’s aerodynamic profile, which favors aggressive styling over fuel efficiency, and the temptation to use the powertrain’s capabilities, which quickly erodes any potential gains. This is not a long-distance cruiser; it’s a performance brute that tolerates highway miles.

Annual fuel cost

The EPA estimates an annual fuel cost of $3,850 for the 2020 BMW X6 M Competition. This figure is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway. The calculation also assumes a national average fuel price. Given the X6 M Competition’s performance, it requires premium gasoline, meaning owners will likely pay more than the average fuel price nationwide.

Real-world expectations

Real-world fuel economy for the X6 M Competition is unlikely to exceed the EPA estimates. Aggressive driving, which is almost unavoidable given the vehicle’s character, will push the MPG figures even lower. Owners who frequently participate in spirited driving events or spend significant time in heavy traffic should anticipate even higher fuel costs. Those considering the X6 M Competition should also factor in other running costs like premium tires, performance brakes, and potentially higher insurance rates.

How it compares

The fuel economy of the X6 M Competition puts it in direct competition with other high-performance SUVs. Consider the Mercedes-AMG GLE 63 S Coupe, which offers similar performance and has an EPA rating of 15 MPG combined. The Land Rover Range Rover Sport SVR, another competitor, manages a slightly lower 17 MPG combined. The Porsche Cayenne Turbo Coupe, with its 541-hp V8, achieves a similar 17 MPG combined. These numbers highlight that the X6 M Competition’s fuel consumption is in line with its direct rivals, suggesting that fuel economy isn’t a primary concern for buyers in this segment. You can also compare all Bmw fuel economy data to see where the x6 m Competition fares against the rest of the BMW linup.

Tips to maximize efficiency

While the X6 M Competition is not designed for fuel efficiency, a few techniques can help mitigate fuel consumption. Gentle acceleration is key; avoiding sudden bursts of speed, especially from a standstill, will significantly reduce fuel consumption. Take advantage of the automatic start/stop system, which shuts off the engine at traffic lights and in stop-and-go traffic, but note that this system can be deactivated when desired.

Ensure that your tires are properly inflated. Underinflated tires create more rolling resistance, which negatively impacts fuel economy. Check the tire pressure regularly and inflate to the recommended pressure listed on the driver’s side doorjamb. Reduce unnecessary weight by removing any unnecessary items from the trunk or rear seats which will increase fuel economy.

Minimize excessive idling. Idling consumes fuel without covering any distance. If you anticipate a prolonged stop, turn off the engine to save fuel. Plan your routes strategically. Avoid congested areas and opt for routes with fewer stop-and-go situations. Maintaining a steady speed on the highway is more fuel-efficient than frequent acceleration and braking.
