19 MPG combined isn’t going to win any awards, but for the 2015 BMW 750i xDrive, it’s simply a price of admission. This isn’t a vehicle purchased for its fuel efficiency; it’s purchased for its effortless power, luxurious appointments, and all-weather security. The typical 750i xDrive buyer prioritizes a commanding driving experience and being cocooned in technological refinement. They understand the thirst of a 4.4-liter, twin-turbocharged V8 sending power to all four wheels and accept it willingly.

City and highway performance

The EPA estimates of 16 MPG in the city and 24 MPG on the highway display the 750i xDrive’s fuel consumption across different driving conditions. The city figure reflects the fuel consumed while navigating stop-and-go traffic, where the engine often operates at less-than-optimal efficiency. Frequent acceleration and braking significantly impact the overall fuel economy.

On the open highway, the 750i xDrive can achieve 24 mpg by settling into a more efficient cruising speed. This also reflects the advanced 8-speed automatic transmission which keeps the engine near peak efficiency.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2015 BMW 750i xDrive is $3,050. This figure is calculated based on driving 15,000 miles per year, with a roughly 55/45 split between city and highway driving, using the national average fuel price at the time of calculation. Fuel costs will vary depending on where you live, how you drive, and current fuel prices. This $3,050 estimate provides a standardized benchmark for comparing fuel expenses of different vehicles.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy for the 2015 BMW 750i xDrive can fluctuate depending on various factors. Aggressive driving, frequent short trips, colder weather, and the use of accessories like air conditioning can all negatively impact fuel consumption.

However, a driver who adopts a more conservative driving style, anticipates traffic flow, and ensures proper tire inflation may see figures closer to or slightly above the EPA estimates.

How it compares

The 2015 BMW 750i xDrive’s fuel economy sits where you might expect in the luxury performance sedan segment, but there are cars that perform better and worse. For example, the Mercedes-Benz S550 4Matic from the same year typically manages around 20 MPG combined, while the Audi A8 4.0T Quattro often comes in slightly lower at 18 MPG combined. A Porsche Panamera 4S, prioritizing sportiness, might also average around 18-19 MPG combined in real-world driving. All Bmw fuel economy data can be compared at FuelEconomyHub.

Tips to maximize efficiency

Use the 750i xDrive’s driving modes. Selecting “Eco Pro” prioritizes fuel efficiency by adjusting throttle response, transmission mapping, and climate control settings. This can significantly improve fuel economy, especially during city driving.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and consuming more fuel. Check your tire pressure regularly and maintain the recommended levels specified on the door placard. Check tire pressure monthly or often.

Avoid aggressive acceleration and braking. Rapid acceleration consumes a significant amount of fuel, while hard braking wastes the kinetic energy you’ve already paid for. Practice smooth, gradual acceleration and anticipate traffic flow to minimize unnecessary braking and maximize 750I MPG across all years.

Keep up with scheduled maintenance. Regular oil changes, air filter replacements, and spark plug maintenance ensure your engine runs at peak efficiency. A well-maintained engine burns fuel more efficiently. A properly maintained BMW requires the proper oil, so research the correct type for the 750i.

Minimize unnecessary weight. Carrying extra weight in the vehicle puts additional strain on the engine, reducing fuel economy. Remove any unnecessary items from the trunk and passenger compartment to lighten the load.
