The 2024 BMW M3 Sedan with its 3.0L inline-six and the 6-speed manual transmission gets 19 MPG combined. An M3 isn’t bought for fuel efficiency. It’s the razor-sharp handling, exhilarating power, and driving joy that matter. Fuel economy is secondary to experiencing one of the best sports sedans. This is a driver’s car that rewards pushing it hard.

City and highway performance

EPA estimates are 16 MPG in the city and 23 MPG on the highway. The city number reflects stop-and-go driving, where the M3’s engine idles more than it performs. The highway number is better, but not great because even at 70 MPH, the M3 prioritizes performance. The engine’s responsiveness tempts drivers to accelerate, negating economy gains. For M3 drivers, the sound and feel are worth it.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 BMW M3 at $3,050. This is based on 15,000 miles per year and average fuel prices. The M3 requires premium fuel, which increases the cost. This reflects owning a performance car. Some may find this daunting, but M3 owners see it as the price to pay.

Real-world expectations

The EPA provides a standard, but real-world MPG varies with driving style and conditions. Drivers who drive aggressively will likely see numbers below the EPA estimates. Those who drive conservatively might achieve slightly better results, but don’t expect economy car numbers. Owning an M3 means accepting its fuel consumption as part of the experience.

How it compares

Consider the competition. The Mercedes-AMG C63 S Sedan offers comparable performance, but typically returns similar fuel economy. The Audi RS5 Sportback, with its turbocharged V6 and all-wheel drive, is more efficient, often achieving around 20-21 MPG combined. The Porsche 718 Cayman is a different class, but offers similar engagement with better fuel economy, often exceeding 22 MPG combined, particularly in the base model. These MPG differences matter less to the typical M3 buyer, who prioritizes the BMW driving experience. For a broader look at the brand, see: all Bmw fuel economy data.

Tips to maximize efficiency

The M3 isn’t designed for fuel efficiency, but steps can improve MPG. Avoid short trips where the engine doesn’t reach operating temperature. Cold starts are fuel-inefficient, so minimizing them helps.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder. Check your tire pressures and inflate them to the recommended levels on the driver’s side doorjamb.

Anticipate traffic flow and avoid aggressive acceleration and braking. Smooth driving is key to maximizing fuel efficiency in any vehicle, including the M3. Use the engine’s torque to your advantage and avoid unnecessary downshifts.

Consider using the M3’s efficiency drive mode if equipped. This mode adjusts engine mapping and throttle response to prioritize fuel economy over performance, though it diminishes the driving experience the car is known for.
