The 2015 BMW M6 Gran Coupe gets 16 MPG combined, according to the EPA. This isn’t a family car pretending to be sporty. It’s a true performance car with a sleek, four-door coupe design. If you want raw power and eye-catching style more than saving gas, the M6 Gran Coupe delivers that.

City and highway performance

The M6 Gran Coupe’s EPA ratings are 14 MPG in the city and 20 MPG on the highway. The city number shows what happens when stop-and-go traffic meets the temptation to unleash the 560 horsepower. On the highway, with a more careful foot, you can reach 20 MPG, but the car’s eagerness makes restraint difficult. Most M6 owners aren’t focused on fuel savings during their daily drive.

Annual fuel cost

The EPA estimates the 2015 BMW M6 Gran Coupe will cost $3,600 per year for fuel. This is based on driving 15,000 miles per year, with a mix of city and highway driving, and using the national average fuel price. This cost comes directly from the M6’s performance and the thirsty 4.4-liter V8 engine. Many buyers are happy to pay that price for the car’s exciting driving experience.

Real-world expectations

The EPA estimates are a standard, but your actual MPG will change based on how you drive, traffic, and maintenance. Quick starts and hard acceleration will lower those numbers, possibly a lot. Driving smoothly and predicting traffic can give you slightly better MPG, especially on long highway trips. Getting better MPG than the EPA estimates in an M6 Gran Coupe takes a lot of self-control.

How it compares

Other high-performance luxury sedans balance power and efficiency in different ways. The Audi RS7, a direct competitor, gets about 18 MPG combined, a little better. The Mercedes-AMG CLS63 S, which is similar in performance, has about the same fuel economy as the M6. You can see differences even within BMW, check the M6 MPG across all years for more data. The Porsche Panamera Turbo has similar performance and fuel economy. The choice depends on styling, brand preference, and how the car drives. Fuel economy is rarely the main thing people consider.

Tips to maximize efficiency

The M6 Gran Coupe wasn’t made for saving gas, but you can still improve fuel economy a bit. Avoid quick acceleration and hard braking. Smooth and slow movements are important for using less gas, even in this type of car. Use the car’s driving mode selector to choose “Efficiency” or “Comfort” mode when you don’t need full performance.

Make sure your tires have enough air. Low tires increase rolling resistance, which lowers fuel economy. Check your tire pressure often and keep them at the recommended levels, which are usually on a sticker on the driver’s side door.

Regular maintenance is needed for best engine performance and fuel efficiency. Follow the service schedule, including oil changes, air filter changes, and spark plug checks. A well-maintained engine is more efficient.

Take out extra weight from the car. Extra items add weight, which makes the engine work harder and use more fuel. Remove unnecessary items from your trunk to reduce weight.
