26 MPG combined is an acceptable figure for the 2025 BMW X2 M35i, especially when you understand what this vehicle is: a stylish, aggressively-tuned compact crossover engineered for driving enjoyment above all else. This isn’t a hybrid aiming for Prius-level efficiency; it’s a performance-oriented BMW, and the fuel economy reflects that.

City and highway performance

The EPA estimates put the X2 M35i at 23 MPG in the city and 32 MPG on the highway. The city number is fairly typical for a turbocharged four-cylinder engine in stop-and-go traffic, where the turbocharger is constantly spooling up and consuming extra fuel. However, the 32 MPG highway figure is surprisingly strong. This suggests the X2 M35i cruises comfortably and efficiently at highway speeds, likely due to the well-calibrated 7-speed automatic transmission (AM-S7) and optimized gearing. Drivers who spend a significant portion of their commute on the open road will appreciate the highway efficiency.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2025 BMW X2 M35i at $2,250. This figure is based on driving 15,000 miles per year and using national average fuel prices. While individual fuel costs will vary depending on driving habits and local fuel prices, $2,250 provides a useful benchmark for understanding the financial implications of owning this vehicle. It’s important to remember that this figure assumes you’re using the recommended fuel, which, given the M35i’s performance-focused engine, likely means premium gasoline.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy often differs. Aggressive driving, frequent short trips, and cold weather can all negatively impact fuel economy. Consequently, X2 M35i owners who prioritize spirited driving should expect to see figures closer to the city estimate, especially in urban environments. Conversely, those who regularly undertake longer highway journeys with a light foot should see numbers approaching, or even slightly exceeding, the 32 MPG highway figure. Understanding X2 MPG across all years can also provide additional insight.

How it compares

The X2 M35i finds itself in a competitive segment. The Mercedes-AMG GLA 35, another performance-oriented compact crossover, achieves a similar 25 MPG combined. Moving outside the German brands, the Acura Integra Type S, a liftback sedan with a focus on driver engagement, matches the X2 M35i’s combined 26 MPG. The comparison matters because the BMW X2 M35i buyer is often cross-shopping these alternatives. These are individuals who prioritize driving dynamics and brand cachet, often willing to accept a slight compromise in fuel economy in exchange for the performance and image they desire. They are willing to pay the premium for the performance and driving experience, and the fuel economy is generally considered an acceptable byproduct of that decision. See all Bmw fuel economy data.

Tips to maximize efficiency

Use the automatic transmission’s Eco Pro mode whenever possible, especially during highway cruising. This mode optimizes shift points and throttle response to prioritize fuel efficiency. While it might dampen the M35i’s sporty character, it can lead to noticeable savings on longer trips.

Ensure your tires are properly inflated to the recommended pressure, which can be found on the driver’s side doorjamb. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check and adjust tire pressure regularly, especially with changes in ambient temperature.

Avoid aggressive acceleration and hard braking. The turbocharged engine is quite responsive, but resist the urge to constantly exploit its power. Smooth, gradual acceleration and anticipatory braking can significantly improve fuel economy, particularly in city driving.

Consider minimizing roof rack use when not needed. Roof racks and cargo carriers add aerodynamic drag, which reduces fuel economy, especially at higher speeds. Removing them when not in use can help streamline the X2 M35i and improve its efficiency.
