19 MPG combined. That’s what awaits anyone considering a 2016 BMW M3. Nobody buys an M3, a car built for surgically precise handling and blistering speed, expecting Prius-like efficiency. This is a performance icon, a four-door sedan (or coupe) that prioritizes driver engagement above all else. Fuel economy is simply the price of admission for the privilege of piloting a legendary machine.

City and highway performance

The official EPA figures peg the 2016 M3 at 17 MPG in the city and 24 MPG on the highway. While 24 MPG might sound respectable on the open road, understand how it’s achieved. A light foot is essential. Use the M3’s immense power even momentarily, and that number will plummet. Stop-and-go city driving, meanwhile, is the M3’s weakness. The turbocharged engine, even with its efficient design, needs fuel to deliver its immediate burst of acceleration out of every corner.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2016 BMW M3 is $3,050. This figure is calculated based on driving 15,000 miles per year, using current national average fuel prices. Keep in mind that premium fuel is mandatory for the M3, impacting the cost. This also assumes a specific percentage split between city and highway driving. Your actual expenses will vary depending on your individual driving habits.

Real-world expectations

Forget the EPA numbers. Enthusiast drivers rarely stick to factory test cycles, and M3 owners are enthusiasts. Expect something lower than 17 MPG in real-world city conditions, and only achieve that 24 MPG highway figure on long, steady cruises. More realistic numbers for mixed driving are in the 15-20 MPG range. Those who frequently exploit the M3’s performance potential can expect even lower fuel economy figures.

How it compares

Compared to its contemporaries, the M3’s fuel economy is about average for its class. The Mercedes-AMG C63 S, for instance, with its strong V8, manages a similar 18 MPG combined. The Audi RS5, another performance coupe, lands around 19 MPG combined. Even the Cadillac ATS-V, a worthy American rival, was around the same 19 MPG mark. However, it is important to note all Bmw fuel economy data compares to similar brands so you can find what is important for your personal needs.

Tips to maximize efficiency

Resist the urge to constantly use full throttle. The M3’s power is intoxicating, but carefully control the accelerator pedal to maintain a steady speed and avoid unnecessary downshifts. The engine’s torque is adequate for most situations without needing to constantly push it to the limit.

Take advantage of the automatic transmission’s Eco Pro mode. This setting remaps the throttle response and shift points to prioritize fuel economy. While it does diminish performance somewhat, it’s effective for less spirited commutes or highway cruising where ultimate power isn’t required.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which negatively impacts fuel economy. Check your tire pressure regularly (every week) and maintain the recommended pressure specified on the door jamb sticker.

Avoid unnecessary idling. Modern engines are designed to be efficient even when started cold. If you’re going to be stopped for more than a minute, it’s generally more efficient to turn off the engine. The M3’s instant restart system makes this convenient.

Regular maintenance is critical. A well-maintained engine runs more efficiently. Follow the manufacturer’s recommended service schedule, including oil changes, air filter replacements, and spark plug replacements. This will ensure optimal performance and fuel economy over the long term. Also, ensure you are aware of the complete M3 MPG across all years!
