The 2017 BMW 640i xDrive Coupe gets 22 MPG combined. While not the most fuel-efficient, it’s designed as a stylish grand tourer. It has a potent inline-six engine, all-wheel drive, and a luxurious interior, for comfortable long trips with style. Buyers of the 640i xDrive Coupe likely value performance, aesthetics, and the BMW brand more than maximizing MPG. They accept the 22 MPG as part of the cost of owning this car.

City and highway performance

EPA estimates for the 2017 BMW 640i xDrive Coupe are 19 MPG in the city and 28 MPG on the highway. This difference is normal for this type of car. The automatic transmission and the inline-six allow for good highway mileage when cruising. However, stop-and-go city driving makes fuel economy worse. These are estimates, so your MPG may be different depending on your driving and traffic. If you are considering this vehicle also make sure to check 640I MPG across all years.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 BMW 640i xDrive Coupe at $2,650. This is based on 15,000 miles per year and average fuel prices at the time. This figure helps compare running costs, but your actual costs may be higher or lower depending on your driving and location because fuel prices change by state. Consider this a benchmark, not an exact prediction.

Real-world expectations

EPA estimates are helpful, but real-world MPG varies. Aggressive driving, frequent short trips, extreme temperatures, and tire pressure affect MPG. If you drive fast in town, expect mileage closer to or below the 19 MPG city number. On long highway trips at consistent speeds, 28 MPG is possible and may even be exceeded. How you drive determines your fuel economy, and being realistic about it is key to figuring out total ownership costs.

How it compares

The 2017 BMW 640i xDrive Coupe is a luxury coupe. Comparisons to similar cars can be helpful. The Mercedes-Benz E400 Coupe (before its model update), with its turbocharged V6, got about 20 MPG city and 29 MPG highway. If you don’t need two doors, the Porsche Panamera is another choice. A base rear wheel drive Panamera with a V6 from the same year got around 21 MPG city and 28 MPG highway and the Audi A7 with its supercharged V6 also achieved similar numbers around 21 City and 29 Highway. Consider these differences when comparing luxury vehicles based on their features and your priorities. You can also find all Bmw fuel economy data on this site.

Tips to maximize efficiency

Use the 640i’s driving modes. “Eco Pro” mode changes the throttle, transmission shift points, and climate control to improve MPG and this can make a difference in the city.

Avoid idling, which wastes fuel. If you’re stopped for more than a minute, turn off the engine.

Keep your tires properly inflated. Low tire pressure increases rolling resistance and reduces MPG. Check tire pressure regularly and inflate to the pressure on the doorjamb sticker.

Use cruise control on the highway. Steady speed improves fuel efficiency and cruise control minimizes acceleration and braking, leading to better gas mileage.

Drive mindfully. Avoid fast acceleration and hard braking. Smooth inputs improve fuel economy and relaxation.
