16 MPG combined is a stark number for the 2021 BMW X4 M 3.0L, and context is immediately needed. This isn’t your neighbor’s sedate X3, the X4 M is a high-performance coupe-SUV that prioritizes blistering acceleration and track-ready handling over using less gas. Its mission is to deliver a thrilling driving experience, and efficiency takes a backseat to that singular goal.

City and highway performance

The EPA estimates the X4 M at 14 MPG in the city and 19 MPG on the highway. The city figure reflects the demands of stop-and-go traffic, where the powerful 3.0L inline-six engine is constantly accelerating the X4 M’s roughly 4,600-pound curb weight. The highway number, while still relatively low, benefits from more consistent speeds, but the vehicle’s aerodynamic profile, or lack thereof given its SUV shape, limits its potential for significant fuel savings.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2021 BMW X4 M is $3,600. This is based on driving 15,000 miles per year and using national average fuel prices. It’s important to acknowledge that individual driving habits, local fuel costs, and the temptation to frequently use the engine’s performance will significantly impact this figure. Expect to exceed this number if you regularly engage in spirited driving or if fuel prices in your area are higher than the national average.

Real-world expectations

Those considering the X4 M likely aren’t prioritizing fuel economy above all else. They’re drawn to its aggressive styling, powerful engine, and engaging driving dynamics. That said, even within this niche, there’s a spectrum of tolerance. Some owners will accept the low MPG as a necessary trade-off for the performance on offer, while others may find themselves wincing at the pump more often than they anticipated. Understanding your own driving style and needs is important before committing to this vehicle. If you are considering other vehicles, you can view all Bmw fuel economy data here. Comparing the X4 MPG across all years can also be informative.

How it compares

The X4 M’s fuel economy lags behind many of its rivals. For example, the Mercedes-AMG GLC 63 S Coupe, while also a high-performance SUV coupe, manages a slightly better 16 MPG city and 22 MPG highway. The Porsche Macan Turbo, known for its performance and handling, achieves around 17 MPG city and 23 MPG highway. Even the Alfa Romeo Stelvio Quadrifoglio, another performance-oriented SUV, boasts figures in the same ballpark. These differences, slight as they may seem at first glance, can add up significantly over time. Someone shopping for these vehicles might be willing to sacrifice a few MPG for the specific performance character of the X4 M, while others may find the alternatives a more palatable compromise.

Tips to maximize efficiency

While the X4 M is not inherently fuel-efficient, there are steps you can take to mitigate its thirst. Avoid aggressive acceleration and hard braking. The X4 M’s powerful engine is tempting to unleash, but smooth and steady driving will significantly improve your fuel consumption. Mastering the art of anticipation in traffic will help you avoid unnecessary stops and starts, conserving fuel in the process.

Select the “Eco Pro” driving mode when performance isn’t a priority. This mode optimizes various vehicle settings to prioritize fuel efficiency, including throttle response and transmission mapping. Even when not engaged in particularly vigorous driving, this mode can make a noticeable difference.

Regularly check your tire pressure and ensure they are inflated to the recommended levels. Underinflated tires increase rolling resistance, which reduces fuel economy. Consult your owner’s manual or the sticker on the driver’s side doorjamb for the correct tire pressure.

Consider reducing your overall driving distance when possible. Combining errands into a single trip, carpooling, or using public transportation can help minimize fuel consumption. This not only saves you money at the pump, but also reduces wear and tear on your vehicle.
