19 MPG combined. That’s what you can expect from the 2016 BMW 650i xDrive Coupe, a number that might surprise some economy car shoppers. But the people who buy this sleek, powerful coupe are probably more interested in its strong twin-turbo V8, confident all-wheel drive, and the distinct style of a large BMW coupe. This isn’t a car bought for its frugality; it’s purchased for its performance, comfort, and status, with fuel costs included in the price.

City and highway performance

The EPA estimates give a clearer picture when separated. The city rating is 16 MPG, reflecting how much fuel is used in stop-and-go driving, made worse by the engine’s large size and turbocharging. The 4.4-liter V8 requires a heavy foot to accelerate from a stop, which lowers MPG. However, on the highway, the 650i xDrive Coupe does better, reaching 24 MPG. You can get this number when cruising steadily, where the engine works most efficiently. The smooth eight-speed automatic transmission also helps to optimize fuel consumption at higher speeds, choosing the correct gear to balance power and efficiency.

Annual fuel cost

Expect to spend about $3,050 per year for fuel with the 2016 BMW 650i xDrive Coupe, based on EPA estimates. This calculation assumes 15,000 miles driven per year, using national average fuel prices. This number will change based on your driving and the current price of gasoline. Driving hard, short trips, and idling will increase fuel use, and your annual fuel cost. However, more highway driving and a gentler driving style can help you approach the EPA estimates. People on the east and west coasts often have higher fuel costs because of higher prices. Think of this number as an estimate, not a guarantee.

Real-world expectations

EPA estimates are helpful for comparison, but actual fuel economy can vary quite a bit. Many 650i xDrive Coupe owners report numbers a little below the EPA’s combined rating, often around 17-18 MPG. This difference can be caused by how you drive, traffic, and even tire pressure. Owners who often use the engine’s high power will probably see even lower numbers. If you drive efficiently and spend a lot of time on the highway you might even reach numbers close to or a little above the EPA’s highway estimate, even while enjoying the engine and handling.

How it compares

The 2016 BMW 650i xDrive Coupe is unique, with performance, luxury, and all-weather capability. Compared to the Mercedes-Benz S550 Coupe (around 20 MPG combined) and the Lexus LC 500 (19 MPG combined), the 650i’s fuel economy is in the middle. The Audi S7, with a smaller engine, gets around 21 MPG combined. However, buyers in this group aren’t just trying to save money; it’s about how efficient these high-performance luxury coupes are compared to each other. Buyers looking for alternatives can see all Bmw fuel economy data to weigh the other factors that outweigh fuel costs for this vehicle.

Tips to maximize efficiency

The 650i xDrive Coupe isn’t meant to save fuel, but you can take steps to improve how much gas it uses. Avoid accelerating too quickly and braking hard. The twin-turbo V8 responds quickly, but a light touch on the gas pedal will save fuel. Use cruise control on the highway to keep a steady speed and avoid unnecessary acceleration.

Make sure your tires have enough air. Tires with low air pressure increase rolling resistance, making the engine work harder and use more fuel. Regularly check your tire pressure and inflate them to the recommended levels on the doorjamb sticker. Also check for damage such as nails and slow leaks.

Try using a lighter touch on the accelerator and selecting “Eco Pro” mode, if the car has it. This mode changes how the throttle responds, how the transmission shifts, and how the climate control works to prioritize fuel efficiency. It might make the car perform slightly worse, but it can noticeably improve MPG, particularly in city driving. Buyers should also verify 650I MPG across all years to identify any gains or losses.

Regular maintenance is important. A well-maintained engine runs more efficiently, saving fuel. Make sure the car gets regular oil changes, tune-ups, and air filter replacements, as recommended by the manufacturer. This also includes checking and cleaning the intake system for carbon buildup.
