23 MPG combined won’t win any fuel efficiency awards, but it’s acceptable for the 2016 BMW 640i xDrive Gran Coupe. Style, luxury, and driving experience are higher priorities than thriftiness. The typical 640i Gran Coupe buyer is a successful professional or entrepreneur who appreciates a finely crafted machine with a powerful engine and all-weather capability. They prioritize how the car makes them feel over saving on premium unleaded. It’s a statement car, and that statement speaks volumes about its owner. The 640i xDrive Gran Coupe offers understated elegance with surprising usability and all-wheel drive confidence other cars in its class do not.

City and highway performance

The EPA estimates the 2016 BMW 640i xDrive Gran Coupe will achieve 20 MPG in the city and 29 MPG on the highway. The 29 MPG is respectable, especially considering the car’s curb weight and standard all-wheel drive system. This allows for comfortable long-distance cruising, making this a surprisingly capable road trip car. The city number, while less impressive, is still competitive within its class. The turbocharged 3.0-liter inline-six blends in with normal traffic, and makes a pleasing sound when merging with interstate traffic. It’s a fuel-versus-fun tradeoff that most owners are happy to make.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2016 BMW 640i xDrive Gran Coupe is approximately $2,500. This estimate is based on driving 15,000 miles per year and using the national average fuel price for premium gasoline, which is the recommended fuel grade for optimal performance. Actual fuel costs will vary depending on your driving habits, local fuel prices, and the amount of miles you actually drive annually.

Real-world expectations

While the EPA estimates provide a useful benchmark, temper expectations with real-world experiences. Owners of the 2016 640I MPG across all years report figures that can fluctuate based on driving style and conditions. Aggressive driving, frequent short trips, and prolonged idling will all negatively impact fuel economy. A relaxed highway cruise at a steady speed will likely yield results that meet or even exceed the EPA’s 29 MPG highway rating. The BMW’s onboard computer provides real-time and average fuel economy readings, which serve as a helpful tool for monitoring consumption and adjusting driving habits.

How it compares

The 2016 BMW 640i xDrive Gran Coupe blends the practicality of four doors with the sleek styling of a coupe. Its fuel economy is generally competitive compared to other similar vehicles. For example, the 2016 Audi A7 3.0T quattro, another stylish four-door coupe with all-wheel drive, achieves an EPA-estimated 24 MPG combined. The Mercedes-Benz CLS400 4MATIC from the same year is rated at 23 MPG combined, matching the BMW. The Porsche Panamera 3.0 is rated at 21 MPG combined. Small differences can add up over time. However, for buyers in this segment, factors like brand cachet, interior quality, and driving dynamics often outweigh marginal differences in fuel efficiency.

Tips to maximize efficiency

Use the BMW’s driving modes. The “Eco Pro” mode optimizes vehicle settings to prioritize fuel efficiency. It reduces throttle response, adjusts the shift points of the automatic transmission, and can even limit the power consumption of auxiliary systems like the air conditioning. For daily commuting situations, using Eco Pro can stretch your fuel dollars.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressures regularly and maintain them at the recommended levels. The correct tire pressure is usually listed on a sticker inside the driver’s side doorjamb.

Minimize unnecessary weight in the vehicle. Carrying excessive cargo adds to the vehicle’s overall weight, negatively impacting fuel economy. Remove any non-essential items from the trunk or rear seats. Every pound counts.

Practice smooth driving techniques. Avoid aggressive acceleration and hard braking, which waste fuel. Anticipate traffic flow and maintain a steady speed whenever possible. The 640i’s engine is more efficient at a steady pace.

Keep up with regular maintenance. A well-maintained engine runs more efficiently. Follow the manufacturer’s recommended maintenance schedule, including oil changes, air filter replacements, and spark plug replacements, to ensure optimal performance and fuel economy.
