23 MPG combined isn’t going to win the 2016 BMW 640i xDrive Coupe any hypermiling awards, but it’s an honest figure for a sleek, all-weather grand tourer with a strong 3.0L turbocharged inline-six engine. This isn’t a car bought by penny-pinchers; it’s a statement piece, a comfortable and capable vehicle for those who value style and performance, and are willing to pay a premium at the pump for the privilege.

City and highway performance

The EPA estimates suggest 20 MPG in the city and 29 MPG on the highway for the 640i xDrive Coupe. While 20 MPG might feel a bit thirsty during stop-and-go urban driving, the highway number is more respectable, aligning with the car’s intended use for long-distance cruising. The all-wheel-drive system (xDrive) does add a small amount of weight and complexity, which can slightly impact fuel economy compared to a rear-wheel-drive model. However, xDrive provides enhanced traction and confidence in inclement weather, a valuable asset for drivers in colder climates.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 BMW 640i xDrive Coupe at $2,500. This calculation is based on driving 15,000 miles per year and using the national average fuel price at the time of calculation. It’s important to remember that this is just an estimate; your actual fuel costs may vary significantly depending on your driving habits, the type of fuel you use, and prevailing fuel prices in your area. For example, aggressive acceleration and frequent short trips will inflate your fuel bill, while consistent highway driving at moderate speeds could bring it down.

Real-world expectations

While the EPA figures provide a baseline, real-world fuel economy often deviates. Many 640i xDrive Coupe owners report slightly lower combined MPG figures, often around 21-22 MPG. This is understandable considering the temptation to exploit the engine’s 315 horsepower and the rewarding driving experience it delivers. The car’s weight and the presence of xDrive also contribute to this difference. Ultimately, your fuel economy will depend on how you drive and where you drive. If you’re consistently flooring the accelerator, expect a lower number. However, with mindful driving, achieving close to the EPA estimates is certainly possible. Always check 640I MPG across all years to understand typical owner reported MPG.

How it compares

Compared to its rivals, the 2016 BMW 640i xDrive Coupe’s fuel economy is generally competitive. The Audi A7 3.0T Quattro, for instance, achieves a similar 24 MPG combined. The Mercedes-Benz CLS400 4MATIC (discontinued after 2018) also delivers comparable fuel economy. However, opting for a higher-performance variant, such as the BMW M6, will invariably result in a significant drop in fuel efficiency. Buyers considering the 640i xDrive Coupe often weigh performance and luxury more heavily than fuel economy, but understanding the comparative landscape is still important. The Porsche Panamera, while offering a plug-in hybrid option for superior fuel efficiency, comes with a significantly higher price tag and caters to a slightly different buyer. Look at all Bmw fuel economy data to get a better feel for the brand’s overall efficiency.

Tips to maximize efficiency

Take advantage of the BMW’s driving modes. The “Eco Pro” mode optimizes various vehicle settings for maximum fuel efficiency, including throttle response and shift points. Using this mode, especially during highway driving, can yield noticeable improvements in MPG.

Ensure your tires are properly inflated. Underinflated tires create more rolling resistance, forcing the engine to work harder and consume more fuel. Regularly check your tire pressure and maintain it at the recommended level specified in your owner’s manual. Even a slight decrease in pressure can negatively affect fuel economy.

Avoid aggressive driving habits. Rapid acceleration and hard braking waste fuel. Smooth, gradual acceleration and anticipating traffic conditions to minimize braking can significantly improve your MPG. Treat the accelerator pedal with respect, and the 640i will reward you with better efficiency.

Minimize excessive idling. If you’re stopped for more than a minute, consider turning off the engine. Idling consumes fuel without moving the car, negatively impacting overall MPG. Modern cars are designed to restart quickly and efficiently, so prolonged idling is rarely necessary.

Keep up with scheduled maintenance. A well-maintained engine runs more efficiently. Ensure you follow the manufacturer’s recommended maintenance schedule, including regular oil changes, air filter replacements, and spark plug inspections. A healthy engine uses fuel more effectively.
