The 2017 BMW 650i xDrive Gran Coupe gets 18 MPG combined. This isn’t a number for those seeking lower fuel costs, as this car prioritizes a strong V8 engine, sleek coupe styling, and all-wheel drive. Fuel efficiency is a secondary concern for buyers drawn to the 650i Gran Coupe’s luxury and performance.

City and highway performance

The EPA estimates the 2017 BMW 650i xDrive Gran Coupe 4.4L 8-cyl gets 15 MPG in the city and 24 MPG on the highway. This difference shows the engine’s higher fuel consumption during stop-and-go driving. The 4.4-liter V8, which produces significant power, requires a considerable amount of fuel to repeatedly accelerate the car’s weight. On the open road, at consistent speeds, the engine operates more efficiently, allowing for the better highway rating. Drivers who frequently encounter heavy urban traffic should expect fuel economy closer to the city estimate, while those who primarily use the car for longer highway journeys might see numbers closer to, or even slightly exceeding, the EPA’s highway rating.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 BMW 650i xDrive Gran Coupe at $3,200. This figure is based on driving 15,000 miles per year, with a mix of city and highway driving, and using national average fuel prices. Your actual fuel costs may vary depending on your driving habits, the type of fuel you use (premium fuel is recommended for optimal performance in the 650i), and fluctuations in fuel prices. The $3,200 is a considerable expense and an important piece of information for potential buyers to consider when estimating their cost of ownership.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy often differs. 650i drivers who enjoy the engine’s reliable power and frequently drive hard can expect to see fuel economy numbers below the EPA estimates. Factors such as weather conditions, tire pressure, and the of use accessories like air conditioning can all impact fuel consumption. It’s realistic to expect a combined fuel economy closer to the low end of the EPA range, particularly with more aggressive driving.

How it compares

The 2017 BMW 650i xDrive Gran Coupe’s fuel economy is predictably lower than some competitors that prioritize efficiency. The Audi A7 3.0T achieves a combined MPG of 24, offering a more fuel-conscious choice for buyers still seeking a luxurious four-door coupe.

The Mercedes-Benz CLS550, with a similar engine displacement, achieves a combined MPG of 20, slightly better than the 650i. Those looking for all Bmw fuel economy data should also compare this model to other BMW offerings. Buyers drawn to the 650i are often willing to accept the lower fuel economy for the specific performance and styling, as well as the specific 650I MPG across all years.

Tips to maximize efficiency

Aggressive acceleration is a major contributor to poor fuel economy. Start smoothly, especially from a standstill, to reduce fuel consumption. Avoid sudden bursts of speed and anticipate traffic flow to minimize unnecessary braking.

Ensure your tires are properly inflated to the recommended pressure. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Regularly check your tire pressure and adjust as needed.

Minimize idling time. If you anticipate being stopped for more than a minute, turn off the engine. Modern engines are designed to restart quickly, and idling wastes fuel.

Use cruise control on the highway when possible. Maintaining a consistent speed helps optimize fuel efficiency. Be mindful of changes in terrain and traffic conditions, and adjust your speed manually when necessary.

Remove unnecessary weight from the vehicle. Extra cargo adds to the weight, requiring the engine to work harder. Remove items you don’t need to carry regularly to improve fuel economy.
