24 MPG combined isn’t going to set any records, but it accurately reflects what the 2023 BMW X4 xDrive30i offers: stylish coupe-like looks and all-weather traction in a compact package that prioritizes driving dynamics over being extremely fuel efficient. This isn’t a vehicle aimed at hypermilers; it’s for those who want BMW performance and aesthetics without needing a larger engine or SUV. The X4 buyer prioritizes style and badge prestige, and accepts the fuel economy as a trade-off.

City and highway performance

The EPA estimates suggest 21 MPG in the city and 28 MPG on the highway. The city figure, affected by stop-and-go traffic and the X4’s curb weight, is the more likely cause for concern if most of your driving is urban-centric. The 28 MPG highway rating is achievable, even commendable, if you resist the urge to push the turbocharged engine. The eight-speed automatic transmission helps here, keeping the engine in its sweet spot for efficiency at cruising speeds. Remember, a heavy foot will quickly diminish those gains.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,400 for the 2023 BMW X4 xDrive30i. This figure is based on driving 15,000 miles per year and using the national average fuel price. Keep in mind, premium fuel is recommended for optimal performance, which often carries a higher price per gallon and can significantly impact your real-world expenditure. Your personal fuel costs may vary depending on your driving habits, the type of fuel you purchase, and how many miles you actually drive.

Real-world expectations

While the EPA provides a standardized benchmark, your experience will likely deviate. Aggressive acceleration, frequent short trips, and extended idling can all lower your MPG numbers. On the other hand, a predominantly highway commute with consistent speeds and gentle throttle inputs may result in numbers closer to, or even slightly exceeding, the EPA’s 28 MPG highway estimate.

Regularly monitoring your X4’s trip computer and paying attention to your driving style will provide a more accurate picture of your fuel consumption.

How it compares

Compared to its rivals, the X4’s fuel economy is competitive, but not class-leading. For example, the Acura RDX, with its standard 2.0L turbo, achieves a slightly better 28 MPG combined in its front-wheel drive configuration, though opting for SH-AWD drops it a bit. The Mercedes-Benz GLC 300 Coupe, another direct competitor, gets around the same 24 MPG combined. The Audi Q5 Sportback, another stylish contender, also mirrors the X4’s fuel economy performance. The X4 buyer isn’t exclusively focused on less gas; they are balancing efficiency with the X4’s sporty driving dynamics and unique styling.

Tips to maximize efficiency

Take advantage of the X4’s Eco Pro driving mode. This setting adjusts the throttle response and transmission mapping to prioritize fuel efficiency. It might slightly dull the driving experience, but it can noticeably improve your MPG, especially in city driving. Consider it a free way to get a few extra miles per gallon on your regular commute.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly and maintain the recommended inflation levels listed on the doorjamb sticker. It’s a simple maintenance item that saves fuel and improves tire life.

Avoid unnecessary idling. Modern engines are surprisingly efficient at restarting, so turning off the engine during prolonged stops, like waiting at a long light or idling in a parking lot, can save fuel. The X4 has auto start-stop feature, but if you find you’re constantly restarting the engine after brief pauses, it can be advantageous to disable it for that specific drive.

Plan your routes strategically. Avoiding congested areas and peak traffic times can significantly reduce stop-and-go driving, which is a major fuel economy killer. Use navigation apps to identify the most efficient routes and stay ahead of potential traffic jams.

Be mindful of your driving style. Smooth acceleration and gentle braking not only contribute to a more comfortable ride but also improve fuel efficiency. Avoid aggressive driving habits, such as flooring the accelerator or hard braking, which waste fuel and increase wear and tear on your vehicle.
