The 2023 BMW M3 Competition Sedan’s 19 MPG combined won’t break any fuel efficiency records. But most buyers are probably more interested in its 503-horsepower engine than fuel economy. The M3 Competition is built for the track but still works as a practical sedan, so its fuel consumption reflects its performance focus.

City and highway performance

EPA estimates show 16 MPG in the city and 23 MPG on the highway. The significant drop in urban environments demonstrates the M3’s nature, as stop-and-go traffic forces its 3.0-liter inline-six to operate inefficiently. However, on the highway, it can achieve 23 MPG when cruising steadily. The eight-speed automatic transmission (S8) selects the right gear to burn fuel efficiently at higher speeds. Still, aggressive driving will quickly reduce that number, even on the open road.

Annual fuel cost

The EPA estimates the 2023 BMW M3 Competition’s annual fuel cost at $3,050, based on 15,000 miles per year of mixed city and highway driving using national average fuel prices. Premium fuel is recommended for the M3 Competition to deliver its best performance, so the estimated fuel cost might be low for many drivers.

Real-world expectations

While the EPA provides a standard measure, the M3 Competition’s real-world MPG can change greatly depending on driving style and conditions. Owners who often use the engine’s full power and drive aggressively will likely see numbers below the EPA estimates. Those who mainly commute and follow speed limits might see figures closer to, or slightly above, the highway rating. The M3 Competition’s fuel economy depends heavily on the driver. It rewards restraint but constantly tempts you to drive fast.

How it compares

The M3 Competition’s fuel economy is typical for the high-performance sedan class. The Mercedes-AMG C63 S Sedan, with its hand-built V8, gets about 18 MPG combined. The Audi RS5 Sportback gets a slightly better 22 MPG combined with its turbocharged V6 and prioritizes all-weather grip and daily usability. The Alfa Romeo Giulia Quadrifoglio, gets around 20 MPG combined. Buyers in this class focus more on the driving experience than fuel consumption, something that manufacturers understand. For a broader perspective, check out M3 MPG across all years to see how this model compares to its predecessors.

Tips to Maximize Efficiency

Select driving modes intelligently. “Efficiency” or “Comfort” mode will reduce throttle response and adjust the transmission’s shift points, which encourages fuel-saving driving. These modes work best for highway cruising and easier driving.

Accelerate and brake smoothly. Avoid sudden acceleration and hard braking, which use more fuel. Gradual acceleration and watching traffic flow will help you keep momentum and reduce fuel use. Using cruise control on the highway can also lead to more consistent fuel consumption.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which lowers fuel economy. Check your tire pressure regularly and inflate them to the pressure on the door jamb sticker.

Remove unnecessary weight. Remove non-essential items from the trunk or passenger area. Extra weight increases fuel consumption, so reducing weight can eventually make a difference. Even removing golf clubs or extra luggage can improve fuel economy.

Service your car regularly. Regular maintenance, including oil changes, air filter replacements, and spark plug maintenance, ensures efficient engine operation. A poorly maintained engine wastes fuel. Consider exploring all Bmw fuel economy data to compare this model with others in the lineup.
