17 MPG combined is what you get for driving the 2023 BMW X4 M. Let’s be honest: nobody buying this high-performance crossover coupe is prioritizing fuel efficiency. They’re after a potent engine, sharp handling, and the undeniable visual swagger of the X4 M’s distinctive shape. But even performance enthusiasts need to understand the implications of that MPG figure.

City and highway performance

The X4 M’s EPA ratings break down to 15 MPG in the city and 20 MPG on the highway. The city figure shows the effect of stop-and-go traffic on the turbocharged 3.0L inline-six. The engine’s eagerness demands fuel. The highway number is slightly better, but still lags behind more common SUVs. Reaching 20 MPG requires careful throttle control; aggressive passing or sustained high speeds (easily achieved in this car) will quickly reduce that number. Remember, consistent driving affects those numbers.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 BMW X4 M at $3,400. This is based on driving 15,000 miles per year and using national average fuel prices. Understand that “national average fuel prices” changes constantly. Depending on location and driving habits, owners could exceed this estimate. Anyone considering this vehicle needs to budget for fuel expenses.

Real-world expectations

Real-world fuel economy for the X4 M will vary quite a bit depending on driving style and environment. Those who frequently push the car should expect MPG figures closer to, or even below, the 15 MPG city rating. Drivers who spend more time on the open road and drive more carefully might see numbers closer to the 20 MPG highway rating, or even a bit better. The X4 M rewards restraint, but its performance potential constantly tests that restraint.

How it compares

Compared to its rivals, the X4 M’s fuel economy is predictably lower. The Mercedes-AMG GLC 43 Coupe, for example, gets a slightly better 20 MPG combined. Audi’s SQ5 manages around 21 MPG combined. Even the Porsche Macan S, another performance crossover, typically achieves around 19 MPG combined. These differences, while small, can add up over a year, further showing the X4 M’s thirstiness. These differences could affect a buyer’s choice.

Tips to maximize efficiency

While the X4 M is not designed for maximum fuel economy, there are ways to minimize its impact. Avoid aggressive acceleration and braking. The engine’s strong torque can lead to wasteful bursts of speed and hard stops. Smooth and steady driving helps save fuel.

Use the driving modes. Selecting “Comfort” or “Eco Pro” modes will alter the throttle response and transmission mapping to prioritize less gas over performance. While it might tame the engine, it can noticeably improve fuel economy, especially during city driving.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which hurts fuel efficiency. Check your tire pressure regularly and maintain the recommended levels specified by BMW, a simple measure that is often overlooked.

Minimize unnecessary weight. Carrying cargo in the X4 M adds load, which requires more energy to accelerate and maintain speed. Remove any items from the vehicle that are not essential.

Consider using cruise control on long highway drives. Maintaining a consistent speed can maximize fuel efficiency. Be mindful of traffic conditions and be prepared to disengage cruise control when necessary.
