19 MPG combined likely won’t concern the typical 2024 BMW M3 Competition sedan buyer. This isn’t a car purchased for fuel efficiency; it’s a surgically precise performance machine, designed to deliver driving thrills above all else. Fuel economy is a secondary consideration for those prioritizing blistering acceleration and track-honed handling.

City and highway performance

The EPA estimates the M3 Competition at 16 MPG in the city and 23 MPG on the highway. These figures reflect the car’s nature. Stop-and-go city driving, with its constant accelerations and decelerations, is where the M3’s high-strung 3.0-liter inline-six is least efficient. The turbochargers are constantly spooling, then relaxing, demanding more fuel to overcome inertia. On the open highway, at a steady cruise, the engine is far more relaxed, allowing for slightly improved mileage. Even on the highway, the temptation to exploit the engine’s power will inevitably lead to a heavier right foot and diminished fuel economy.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2024 BMW M3 Competition is $3,050. This figure is based on driving 15,000 miles per year and using national average fuel prices. Premium fuel is required for optimal performance, adding to the overall cost. This $3,050 figure offers a benchmark, but individual driving habits and local fuel prices will dramatically influence your actual spending at the pump.

Real-world expectations

The EPA provides a useful baseline, but real-world MPG for the M3 Competition is highly dependent on driving style. If the car is used primarily for commuting in heavy traffic, expect numbers closer to the city rating, possibly even lower. However drivers who frequently take longer trips on the highway, and who resist the urge to constantly engage Sport or Sport Plus mode, might see figures closer to, or slightly exceeding, the EPA’s highway estimate. For those who regularly track their M3, MPG will plummet. Single digits are not out of the question during spirited driving sessions.

How it compares

The M3 Competition’s fuel economy is largely in line with its direct competitors, though nuances exist. The Mercedes-AMG C63 S sedan, with its handcrafted 4.0-liter V8, typically delivers similar, or slightly worse fuel economy, hovering around 18 MPG combined. The Audi RS5 Sportback, despite its different body style, competes in the same performance bracket and achieves roughly 18 MPG combined as well. A similarly equipped Cadillac CT5-V Blackwing makes around 15 MPG combined. These figures show that high performance generally comes at the expense of fuel efficiency. For those seeking better mileage in a Bmw sports sedan, consider exploring all Bmw fuel economy data, or researching M3 MPG across all yearsto identify more efficient versions or model years. Within the M3 range, all-wheel drive models may also have a slight impact to fuel economy.

Tips to maximize efficiency

Use driving modes carefully. The M3 Competition allows for customization of various driving parameters. Selecting the “Comfort” mode for daily commuting smooths out throttle response and softens gear changes, reducing unnecessary fuel consumption. Resist the urge to constantly drive in Sport or Sport Plus modes unless you’re on a track or a truly engaging stretch of road.

The M3 Competition’s automatic transmission is programmed for both lightning-fast shifts when desired, and efficient cruising when appropriate. Allow the transmission to shift naturally and avoid excessive use of the paddle shifters during regular driving. This allows the car to remain in higher gears when possible, thus saving fuel.

Pay attention to tire pressures. Properly inflated tires reduce rolling resistance, a significant factor in fuel economy. Check tire pressures regularly, especially before long trips, and inflate them to the manufacturer’s recommended settings. Under-inflated tires not only decrease fuel efficiency but also compromise handling and tire wear.

Minimize unnecessary weight. The more weight the engine has to move, the more fuel it consumes. Remove any unnecessary items from the trunk and passenger compartment to reduce the vehicle’s overall weight. This might seem insignificant, but every little bit helps, especially in city driving.

Anticipate traffic flow. Aggressive acceleration and braking consume significantly more fuel than smooth, gradual driving. Anticipate traffic conditions and maintain a consistent speed whenever possible. Avoid sudden bursts of acceleration and hard braking by looking further ahead and planning your moves accordingly.
