19 MPG combined won’t win any fuel economy awards. The 2015 BMW 650i xDrive Gran Coupe, with its strong 4.4L twin-turbo V8, isn’t about saving fuel. It’s about effortless power, luxurious features, and a distinctive coupe-like shape on a four-door sedan. Its buyers aren’t prioritizing efficiency; they’re prioritizing the driving experience and the prestige of owning a high-performance BMW. If you are looking for all Bmw fuel economy data, you can find it on our site.

City and highway performance

The EPA estimates 16 MPG in the city and 24 MPG on the highway for the 650i xDrive Gran Coupe. The city figure shows the engine’s thirst when navigating stop-and-go traffic, where the turbos are constantly spooling up and down. The highway figure, while still not stellar, is more respectable because of the smooth-shifting 8-speed automatic transmission that allows the engine to cruise at lower RPMs. However, aggressive acceleration, which is tempting in this car, will quickly lower both figures. Wind resistance affects fuel economy. The coupe-like design looks great but it makes it harder to maximize fuel economy.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2015 BMW 650i xDrive Gran Coupe at $3,050. This figure is based on driving 15,000 miles per year and using national average fuel prices. Premium fuel is recommended for optimal performance, so you’ll be paying more per gallon than owners of vehicles that accept regular unleaded. If you drive significantly more than 15,000 miles per year, or if fuel prices in your area are higher than the national average, your actual fuel costs will be higher.

Real-world expectations

Don’t expect to consistently achieve the EPA’s numbers. In real-world driving, 19 MPG combined will likely be optimistic. Expect something closer to 15-17 MPG in mixed driving conditions, especially if you enjoy the car’s prodigious power. On long highway trips, you might approach 24 MPG if you maintain a steady speed and avoid excessive acceleration. However if you are interested in searching 650I MPG across all years, this resource is available.

How it compares

The 650i’s fuel economy is generally in line with other high-performance luxury sedans of its era. The Mercedes-Benz CLS550, with a similar twin-turbo V8, achieves comparable figures, around 17 MPG city and 25 MPG highway. The Audi S7, with its turbocharged V8, is slightly better, around 17 MPG city and 27 MPG highway. A Porsche Panamera S, while offering similar performance, might achieve slightly better combined economy because of its lighter weight and more advanced engine technology. These differences are often negligible to the buyer in this segment, where performance and prestige are important.

Tips to maximize efficiency

Resist the urge to constantly exploit the engine’s power. The 650i’s V8 is intoxicating, but every hard acceleration run burns fuel. Smooth, gradual acceleration will dramatically improve fuel economy.

Take advantage of the car’s driving modes. The “Eco Pro” mode, if equipped, adjusts the engine and transmission mapping for maximum efficiency. It will dull throttle response, and cause shifts sooner, but it can make a difference on longer trips.

Ensure your tires are properly inflated. Under-inflated tires increase rolling resistance, which negatively impacts fuel economy. Check your tire pressures regularly and maintain them at the recommended levels.

Reduce unnecessary weight. Extra cargo in the trunk adds weight, forcing the engine to work harder. Remove any unnecessary items to improve fuel efficiency.

Consider the route you are taking. Avoiding stop and go traffic will allow the car to consume less fuel. When planning your trip, consider the amount of lights or highway speed that may affect how you use your fuel.
