The 2020 BMW 750i xDrive achieves 20 MPG combined. This figure probably won’t shock or dissuade buyers looking for this type of luxury performance sedan. This isn’t basic transportation. It’s a statement, a mobile display of power and privilege. The fuel bill is simply part of ownership.

City and highway performance

The EPA estimates the 2020 BMW 750i xDrive gets 17 MPG in city driving and 25 MPG on the highway. These figures reflect the trade-off between performance and efficiency. The 4.4L twin-turbo V8 delivers strong acceleration and requires a lot of fuel when driven hard. The highway number represents a scenario where the engine cruises more efficiently, helped by the smooth eight-speed automatic transmission (S8) and the relaxed demands of steady-state driving. The xDrive all-wheel-drive system enhances traction and stability, but also adds weight and driveline losses, increasing fuel consumption.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 BMW 750i xDrive at approximately $2,900. This is based on driving 15,000 miles per year and using national average fuel prices. Keep in mind that premium fuel is required for optimal performance, so those EPA “national average fuel prices” might be lower than what 750i xDrive owners actually pay. It’s a significant figure, but for buyers considering a six-figure luxury sedan, it’s more of a footnote. Those researching 750I MPG across all years will likely see some variation due to fuel price changes and minor vehicle updates.

Real-world expectations

EPA estimates are a standard benchmark, but real-world fuel economy varies based on driving habits, traffic, and weather. Owners who frequently use the engine’s power and drive aggressively will likely see figures below the EPA estimates. Those who drive more conservatively and accelerate smoothly may achieve figures closer to, or slightly above, the official ratings. Leaving the car idling for long periods, especially in cold weather, will also dramatically reduce your miles per gallon.

How it compares

Fuel economy is rarely a primary selling point for large, luxury performance sedans with all-wheel drive. The Mercedes-Benz S560 4Matic, equipped with a V8 engine, posts an EPA-estimated 17 MPG city and 27 MPG highway. The Audi A8 55 TFSI quattro, with its turbocharged V6, manages 19 MPG city and 28 MPG highway. Even the Porsche Panamera 4S, with its focus on performance, achieves similar figures. The 750i xDrive’s 20 MPG combined rating is in line with its competitors, so it’s probably not a reason for prospective buyers to look at all Bmw fuel economy data within this class.

Tips to maximize efficiency

Use the car’s driving mode selector. The “Eco Pro” mode optimizes engine and transmission settings for fuel efficiency. It may slightly dampen throttle response, but it can make a difference in urban driving or long highway trips.

Maintain proper tire inflation. Under-inflated tires increase rolling resistance, forcing the engine to work harder. Check tire pressures regularly and inflate them to the recommended levels, which are on a sticker inside the driver’s side doorjamb or in the owner’s manual.

Avoid excessive idling. Modern engines operate efficiently even when warm. Turning off the engine during extended stops, such as waiting in a parking lot, can save fuel over time.

Plan routes strategically. Pick routes that minimize stop-and-go traffic and prioritize steady speeds to improve fuel economy. Use navigation apps to find the most efficient routes, even if they are slightly longer.
