The 2021 BMW M235i xDrive Gran Coupe gets 26 MPG combined, defining it as a performance-oriented compact car that asks for some compromises at the pump. This four-door “coupe” isn’t chasing Prius-level efficiency; it’s prioritizing driving engagement and a sporty character, and its fuel economy reflects that.

City and highway performance

The EPA estimates the M235i xDrive Gran Coupe will achieve 23 MPG in the city and 32 MPG on the highway. These figures suggest that drivers who primarily use the car for urban commutes, with frequent stop-and-go traffic, will likely see numbers closer to the lower end. On the other hand, those who spend more time on the open road, maintaining consistent speeds, are more likely to approach or even exceed the 32 MPG highway estimate. The xDrive all-wheel-drive system enhances traction and handling, but it also contributes to a slight reduction in fuel economy compared to front-wheel-drive alternatives.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 BMW M235i xDrive Gran Coupe at $2,250. This is based on driving 15,000 miles per year and using the national average fuel price at the time of calculation. Individual fuel costs can vary significantly depending on driving habits, fuel prices in your specific location, and the type of fuel used.

Real-world expectations

The EPA estimates provide a useful baseline, but real-world fuel economy can differ. Aggressive driving, frequent short trips, and carrying extra weight can all negatively impact fuel efficiency. Owners report figures close to the EPA estimates, but some experience slightly lower numbers, particularly in demanding driving conditions. Owners prioritizing fuel conservation can likely meet or exceed the EPA numbers by driving conservatively and using the car’s Eco Pro driving mode.

How it compares

The M235i xDrive Gran Coupe’s fuel economy positions it roughly in the middle of its competitive set. The Mercedes-AMG A35 Sedan, a direct rival offering similar performance and all-wheel drive, achieves an EPA-estimated 25 MPG combined. The Audi S3, another all-wheel-drive competitor, posts 26 MPG combined, matching the M235i. Buyers prioritizing fuel efficiency might consider the Acura Integra, which can reach 30 MPG combined, albeit with less horsepower and a less premium badge. For those seeking even more efficiency while maintaining a luxury feel, a Lexus IS 300 RWD delivers 25 MPG combined. The M235i buyer isn’t focused on saving money at the pump necessarily, but this comparison gives crucial context as to the cost of the BMW’s distinctive style and performance.

Tips to maximize efficiency

Use the M235i’s selectable driving modes. The Eco Pro mode optimizes various vehicle settings, including throttle response and shift patterns, to prioritize fuel efficiency. While it may somewhat reduce the car’s sporty feel, it can make a noticeable difference on longer drives.

Monitor your tire pressure regularly. Properly inflated tires reduce rolling resistance, improving fuel economy and extending tire life. The M235i’s tire pressure monitoring system (TPMS) can alert you to any significant deviations from the recommended pressure.

Avoid unnecessary idling. Modern engines are designed to be shut off when stopped for extended periods. Idling consumes fuel without covering any distance, so turn off the engine if you anticipate being stationary for more than a minute. The auto start/stop feature can help with this, though some drivers prefer to disable it.

Anticipate traffic flow and avoid aggressive acceleration and braking. Smooth, consistent driving is more fuel-efficient than a stop-and-go style. Using cruise control on the highway contributes to steady speeds and optimized fuel consumption.

Reduce unnecessary weight inside the vehicle. Extra cargo increases the vehicle’s overall weight, impacting fuel efficiency. Removing unnecessary items from the trunk and passenger compartment can incrementally improve MPG. A roof rack that’s not in use should also be removed because it adds wind resistance.
