20 MPG combined is what you get with the 2019 BMW 750i xDrive. This executive sedan isn’t chosen for being economical. It’s chosen for effortless power, supreme comfort, and the prestige of the BMW badge. Fuel consumption matters less than the joy of driving a twin-turbo V8 with all-wheel drive.

City and highway performance

The EPA estimates of 17 MPG in the city and 25 MPG on the highway show the 750i xDrive’s nature. In town, the 4.4L V8 requires more fuel to move its 4,600+ pounds from stoplight to stoplight. The automatic transmission is smooth, but the engine’s eagerness is always present. On the open road, the 750i xDrive performs well. Its long wheelbase and tuned suspension provide a comfortable ride, and the V8 cruises at highway speeds, delivering decent fuel economy for its size and power.

Annual fuel cost

The EPA estimates that the 2019 BMW 750i xDrive will cost about $2,900 per year to fuel. This is based on driving 15,000 miles annually, with 45% in the city and 55% on the highway, using national average fuel prices. Fuel costs will change based on driving habits, local fuel prices, and the amount of city versus highway driving. More city miles will mean a higher annual cost.

Real-world expectations

The EPA estimates are a baseline. Real-world fuel economy for the 2019 BMW 750i xDrive can change a lot. Drivers who accelerate hard, use the Sport driving mode often, or drive in stop-and-go traffic will probably see numbers below the EPA estimates. Drivers who accelerate smoothly, use the Eco Pro driving mode, and mostly drive on the highway might get numbers close to or even above the EPA’s 25 MPG highway rating. Expect that the real number will be around 20 MPG.

How it compares

The 2019 BMW 750i xDrive’s fuel economy is what you expect for large, luxurious sedans with strong engines and all-wheel drive. The Mercedes-Benz S560 4MATIC, with a similar twin-turbo V8, has almost identical EPA ratings: 17 MPG city, 27 MPG highway. Buyers in this segment will compare these vehicles, they know there are MPG differences, but they care more about other things. Audi’s A8 55 TFSI has similar features with better gas mileage because of its turbocharged V6 and mild-hybrid system, delivering a combined 22 MPG. For buyers who value fuel efficiency more, the A8 is a good choice, but it doesn’t have the 750i xDrive’s power. It is beneficial, also, to compare the 750I MPG across all years for a broader picture.

Tips to Maximize Efficiency

Use the Eco Pro driving mode. This mode changes the engine, throttle, and transmission to save fuel. It might make performance a little worse, but it can improve MPG, especially in city driving.

Keep a steady speed and don’t accelerate hard if you can avoid it. The 750i xDrive’s engine is tempting, but it will use gas quickly. Smooth acceleration is important to getting better mileage.

Make sure your tires have enough air. Underinflated tires make it harder to roll, which reduces fuel economy. Check your tire pressures regularly and inflate them to the levels on the sticker on the driver’s side door.

Don’t idle for too long. Letting the engine idle uses fuel without going anywhere. If you’re stopped for more than a minute or two, turn off the engine. The 750i starts again quickly.

Think about using cruise control on the highway. Cruise control helps keep a consistent speed, which can improve fuel economy by not speeding up and slowing down as much. This works well on flat, open roads.
