The 2022 BMW M4 Competition M xDrive Convertible gets 18 MPG combined. This isn’t a misprint, it’s the price you pay for open-air thrills and fast acceleration in a high-performance machine. People who buy this car aren’t focused on efficiency. They’re buying a statement, a driving experience, and a rush of adrenaline. Fuel economy is just a factor they acknowledge.

City and highway performance

EPA estimates for this M4 variant are 16 MPG in the city and 23 MPG on the highway. The city figure reflects urban driving’s stop-and-go nature, where the M4’s strong turbocharged engine and all-wheel-drive system are constantly working. The highway MPG shows the engine’s potential for better efficiency when cruising. The temptation to use the M4’s power will likely reduce that number for most drivers. This car invites spirited driving, and that rarely translates to optimal fuel consumption.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 BMW M4 Competition M xDrive Convertible at $3,200. This is based on driving 15,000 miles per year and using national average fuel prices. Considering the M4’s performance and the likelihood that owners will use premium fuel, consider this a baseline. Drivers who frequently drive aggressively or primarily use the car for short city trips can expect to exceed this annual cost.

Real-world expectations

The EPA provides a standard benchmark, but real-world fuel economy depends on driving habits. M4 owners who prioritize fuel conservation and spend time on the highway might see figures close to the EPA estimates. However, those who regularly exploit the car’s performance, participate in track days, or mostly drive in congested areas will likely see lower MPG numbers. The “M” badge indicates a vehicle designed for performance. The fuel consumption reflects that.

How it compares

Compared to other high-performance convertibles, the M4’s fuel economy shows its position. The Porsche 911 Carrera S Cabriolet gets a slightly better 20 MPG combined, but it costs more. The Audi RS5 Cabriolet, with its 2.9-liter V6, gets a similar 18 MPG combined to the M4. All Bmw fuel economy data shows that the M4’s consumption is on the higher end. People considering these vehicles are less concerned with slight MPG variations and more focused on driving dynamics, brand reputation, and ownership.

Tips to maximize efficiency

Minimize aggressive acceleration. The M4’s twin-turbo engine delivers power, but each burst of acceleration burns extra fuel. Smooth acceleration will help to conserve fuel, especially in city driving. Use the car’s drive modes wisely. The M4 offers drive modes, including an “Efficiency” or “Comfort” mode. Selecting this will alter the car’s engine mapping and throttle response to prioritize fuel economy.

Maintain proper tire inflation. Keeping your tires inflated reduces rolling resistance and improves fuel efficiency. Check your tire pressure regularly, especially before long trips. Avoid unnecessary idling. Modern engines don’t need to be warmed up for extended periods. If you’re stopped for more than a minute or two, turn off the engine to save fuel.

Plan your routes. Avoid congested areas and peak traffic times. Routes with fewer stops can improve your fuel economy. Consider using cruise control on the highway. Maintaining a consistent speed on the highway can help to optimize fuel efficiency. Be mindful of traffic conditions and adjust your speed.

Lighten the load. Weight in the vehicle reduces fuel economy. Remove unnecessary items from the trunk to minimize the load the engine has to carry.
