20 MPG combined won’t win any fuel-sipping awards, but for the 2016 BMW 650i Gran Coupe, it’s almost irrelevant. This isn’t a car for those prioritizing lower fuel costs; it’s a statement of performance and style. The 650i Gran Coupe customer wants presence, a growling V8, and the distinctive silhouette of a four-door coupe. They accept the fuel consumption as a trade-off for the thrill this car delivers.

City and highway performance

The EPA estimates the 2016 BMW 650i Gran Coupe at 17 MPG in the city and 25 MPG on the highway. The city figure reflects stop-and-go traffic, where the 4.4L twin-turbo V8 spends much of its time idling or accelerating. The highway number is more appealing. At cruising speeds, the eight-speed automatic transmission settles into a relaxed overdrive, allowing for more economical operation.

While 25 MPG might not sound impressive, it enables comfortable long-distance journeys without constant fuel stops. The “S8” designation in the EPA data refers to this 8-speed Steptronic transmission, known for its smooth shifts and ability to optimize both performance and fuel economy.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 BMW 650i Gran Coupe is $2,900. This figure is based on driving 15,000 miles per year and assumes national average fuel prices. Remember that costs may vary depending on local fuel prices and individual driving habits. Consider it a benchmark to get a sense for how this car compares against other vehicles. It’s also a figure that many 650i Gran Coupe owners likely budget for, given the overall cost of ownership for a car in this class.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy can vary. Aggressive driving, frequent short trips, and heavy traffic will negatively impact fuel consumption. A driver who spends time on the highway, using cruise control and anticipating traffic, may see numbers closer to or exceeding the EPA highway estimate. Some owners say that achieving 25 MPG on long highway trips is possible, though city driving will lower the average. The 650i’s performance is alluring, and resisting the urge to tap into that power will be a challenge.

How it compares

The 2016 BMW 650i Gran Coupe’s fuel economy is similar to its rivals. The Mercedes-Benz CLS550, another four-door coupe with a V8 engine, achieves a similar 17 MPG city and 25 MPG highway. The Audi S7, with its turbocharged V8, manages a slightly better 17 MPG city and 27 MPG highway. The Porsche Panamera 4S, known for its sporty dynamics, comes in around 18 MPG city and 28 MPG highway. These differences are unlikely to be a deciding factor for buyers in this segment. They are more concerned with styling, performance, and brand appeal than a few extra miles per gallon. Compare 650I MPG across all years to get a full view of this model’s fuel consumption history.

Tips to maximize efficiency

The 650i Gran Coupe’s twin-turbo V8 rewards smooth driving. Avoid aggressive acceleration and hard braking when possible. Anticipate traffic and maintain a steady speed. The less you call upon the turbos, the less fuel you’ll burn.

Use the car’s driving modes. Selecting “Eco Pro” mode will remap the throttle response and shift points to prioritize fuel efficiency. While it might reduce performance slightly, it can make a noticeable difference in city driving.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, making the engine work harder and reducing fuel economy. Check your tire pressure regularly and inflate to the recommended levels, typically found on a sticker inside the driver’s side door jamb.

Consider your route and timing. Avoid peak traffic when possible. Stop-and-go traffic hurts fuel economy. Planning your trips to avoid congestion can improve your MPG, especially in urban environments.
