18 MPG combined is unlikely to deter anyone seriously considering the 2022 BMW M3 Competition M xDrive Sedan. This isn’t a car bought for its frugality; it’s a focused performance machine that happens to have four doors and a (relatively) usable back seat. Fuel consumption is simply the cost of admission to a world of twin-turbocharged power and all-wheel-drive grip. Those seeking ultimate efficiency should look elsewhere; M3 buyers prioritize blistering speed and track-day performance.

City and highway performance

The EPA estimates the M3 Competition M xDrive achieves 16 MPG in the city and 22 MPG on the highway. The city figure reflects stop-and-go traffic, where the 3.0L inline-six is working harder and the turbos are constantly spooling. The highway number still speaks to the car’s performance. Even at steady cruising speeds, the M3’s engine is tuned for immediate responsiveness, and its gearing encourages frequent downshifts for overtaking. This isn’t a relaxed cruiser; it’s ready to unleash its power. Buyers viewing M3 MPG across all years recognize this.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2022 BMW M3 Competition M xDrive is $3,200. This is based on driving 15,000 miles per year and using the national average fuel price at the time of calculation, which is subject to change. It’s a useful benchmark, but individual expenses will vary based on driving habits and local fuel costs. Drivers who spend more time in stop-and-go traffic or who frequently engage the M3’s Sport and Sport Plus driving modes can expect to exceed this amount, making fuel expenses a significant part of ownership.

Real-world expectations

While the EPA provides an estimate, real-world fuel economy for the M3 Competition M xDrive depends on driving style. Those with a lead foot can expect to see numbers below the official ratings, particularly in the city. Conversely, drivers who prioritize smooth acceleration, anticipate traffic flow, and make greater use of the car’s Eco Pro mode could potentially achieve figures closer to the EPA’s estimates on the highway. The M3’s performance makes aggressive driving tempting, often negating efforts to conserve fuel.

How it compares

Compared to its direct rivals, the M3 Competition M xDrive’s fuel economy is similar. The Mercedes-AMG C63 S Sedan, with its V8 engine, typically delivers slightly lower figures, around 17 MPG combined. The Audi RS5 Sportback, with its slightly less powerful V6, may achieve a marginally better combined MPG, perhaps around 19-20 MPG. The Cadillac CT5-V Blackwing, another V8 competitor, will likely be even thirstier than the AMG. For the M3 buyer, these differences are rarely a deciding factor because performance and driving dynamics are more important than saving a few dollars at the pump, and they’re already prepared for higher fuel costs. Consumers looking through all Bmw fuel economy data will view this model as a unique offering.

Tips to maximize efficiency

While the M3 isn’t designed for hypermiling, using a few driving habits can help squeeze out a few extra miles per gallon.

Use the Eco Pro driving mode during commutes or on long highway stretches. This mode alters the throttle response and shift patterns to prioritize fuel efficiency without sacrificing performance.

Resist accelerating hard from a standstill. Smooth, gradual acceleration saves fuel and reduces wear on the tires and drivetrain. Using launch control repeatedly will quickly negate any fuel-saving efforts.

Maintain proper tire inflation. Under-inflated tires increase rolling resistance, forcing the engine to work harder and consuming more fuel. Check your tire pressures regularly and inflate them to the recommended levels, found on the sticker inside the driver’s side door jamb.

Avoid excessive idling and if you’re stopped for more than a minute or two, turn off the engine. Modern engines are designed to restart quickly and efficiently, and idling wastes fuel.

Plan your routes carefully to avoid stop-and-go traffic and detours. A shorter, smoother route can make a difference in fuel consumption, particularly in urban environments.
