27 MPG combined won’t win any awards for less gas, but in the 2025 BMW M235 xDrive Gran Coupe, it’s an acceptable trade-off. This isn’t a car for hypermilers; it’s a sharply styled, compact performance sedan that prioritizes driving enjoyment and all-weather grip. The target buyer here is someone who values the BMW badge, appreciates a responsive engine, and needs practicality that a true coupe simply can’t offer. Fuel economy is less important but not entirely ignored.

City and highway performance

The M235’s EPA ratings break down to 24 MPG in the city and 33 MPG on the highway. The city figure reflects the realities of stop-and-go traffic, where the 2.0L turbocharged engine works harder to accelerate and maintain momentum. The xDrive all-wheel-drive system, while providing excellent traction, also adds weight and friction that slightly impacts fuel economy. Out on the open road, the M235 fares better. The smooth-shifting 7-speed automatic transmission can lock up the torque converter for improved efficiency at cruising speeds, and the engine’s strong low-end torque allows it to maintain speed with minimal throttle input. The 33 MPG highway number is achievable if you resist the urge to constantly exploit the engine’s ample power.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2025 BMW M235 xDrive Gran Coupe at $2,150. This figure is based on driving 15,000 miles per year and using the national average fuel price. Your actual fuel costs will vary depending on your driving habits, the type of fuel you use, and local fuel prices. If you predominantly drive in the city or have a lead foot, expect to exceed this estimate. However, if you log mostly highway miles and drive conservatively, you might save a bit of money each year.

Real-world expectations

While the EPA provides a standardized benchmark, real-world fuel economy often differs. Owners of the M235 can typically expect to see figures close to the EPA’s estimates, with some variation depending on their driving style. A mix of spirited driving and city commuting might yield an average of around 25 MPG, while highway cruising could push the number closer to 30 MPG. The M235 MPG across all years shows a consistent trend in this segment.

How it compares

The M235 xDrive Gran Coupe competes in a segment that includes other sporty compacts with similar performance aspirations. The Mercedes-AMG CLA 35, for example, delivers similar performance but achieves an EPA-estimated 25 MPG combined. The Audi S3, another direct competitor, also lands around 26 MPG combined. Even the Acura Integra Type S, while front-wheel drive, boasts around 24 MPG combined which shows how high performance demands more fuel. The M235’s fuel economy is therefore competitive, but not class-leading. The comparison is important because buyers in this segment often evaluate vehicles based on a combination of performance, luxury, and efficiency. While outright fuel economy may not be the top priority, it is still a factor in the overall ownership experience. For all Bmw fuel economy data, see our research pages.

Tips to maximize efficiency

Be mindful of your right foot. The M235’s turbocharged engine responds instantly to throttle inputs, but aggressive acceleration consumes fuel. Smooth and progressive acceleration will help you maintain better fuel economy, particularly in city driving where frequent stops and starts are common.

Take advantage of driving modes. The M235 offers various driving modes, including an Eco Pro mode that optimizes engine and transmission settings for maximum efficiency. Selecting this mode can noticeably improve fuel economy during highway driving when performance isn’t a primary concern. Eco Pro mode typically reduces throttle response and modifies the shift schedule to keep the engine operating at lower RPMs.

Maintain proper tire pressure. Underinflated tires increase rolling resistance, which forces the engine to work harder and consumes more fuel. Check your tire pressure regularly and inflate them to the recommended pressure listed on the doorjamb sticker. Even a few PSI difference can negatively impact fuel economy. Consider this a general rule for good car maintenance, not just for the M235.

Avoid excessive idling. Letting your engine idle for extended periods consumes fuel without going anywhere. If you’re stopped for more than a minute or two, it’s more efficient to turn off the engine. Modern engines restart quickly and reliably, so you won’t experience any significant inconvenience.

Keep up with scheduled maintenance. Regular maintenance, such as oil changes and air filter replacements, ensures your engine is running efficiently. A clean air filter allows the engine to breathe more easily, while fresh oil reduces friction and wear, both of which contribute to improved fuel economy.
