The 2022 BMW 750i xDrive sedan gets 19 MPG combined. It’s not trying to be a Prius. The 750i xDrive is for affluent individuals who want power, luxury, and all-weather confidence. For these buyers, fuel economy is a secondary concern, a compromise for the twin-turbo V8 and all-wheel drive.

City and highway performance

The EPA estimates the 750i xDrive gets 17 MPG in the city and 24 MPG on the highway. The city figure shows how much gas the engine uses in stop-and-go traffic, because of the car’s weight and continuous acceleration. On the open road, the 750i xDrive does better, using its smooth eight-speed automatic transmission and relaxed engine speed at cruising velocity. Even on the highway, the powerful V8 requires premium fuel to deliver its performance.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 BMW 750i xDrive at $3,050. This is based on driving 15,000 miles per year, with 45% of those miles driven in the city and 55% on the highway, using the national average fuel price. This is an estimate, and your actual fuel costs will vary depending on your driving habits, local fuel prices, and the type of driving you do. The 750i needs premium gasoline, so fuel price changes can impact the annual fuel bill.

Real-world expectations

The EPA estimates are a benchmark, but real-world fuel economy often changes. Drivers who accelerate quickly or use the car’s Sport mode a lot may see MPG closer to the low teens, especially in cities. Those who accelerate smoothly and drive on the highway can get figures closer to, or even above, the EPA estimates. Tire pressure, outside temperature, and even the type of fuel used can also change observed MPG. You can always check 750I MPG across all years to help you with your expectations.

How it compares

The 750i xDrive’s fuel economy is about what you’d expect. The Mercedes-Benz S580 4Matic, with its 4.0L twin-turbo V8, gets a similar 16 MPG city and 25 MPG highway. The Audi A8 L 55 TFSI, using a 3.0L turbocharged V6, offers slightly better economy at 19 MPG city and 28 MPG highway, showing the efficiency benefits of a smaller engine. The Lexus LS 500 AWD, powered by a 3.4L twin-turbo V6, gets 17 MPG city and 27 MPG highway. Buyers considering the 750i should know that other options exist, and compromising a bit in MPG is the price for its V8 power and luxury. Be sure you’re aware of all Bmw fuel economy data to help with your decision.

Tips to maximize efficiency

Drive smoothly and gradually. Avoid fast acceleration and hard braking, as these use more fuel. Watch traffic and keep a steady speed. The 750i xDrive has a turbocharged engine with an electric motor; gentle inputs yield improved efficiency.

Make sure your tires are properly inflated. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure and keep it at the recommended pressure in your owner’s manual or on the doorjamb sticker. Even a few PSI difference can impact fuel consumption.

Don’t idle. Idling uses fuel without going anywhere. If you’ll be stopped for more than a minute or two, turn off the engine. The 750i xDrive’s start/stop system does this automatically, but you can save more fuel manually.

Remove extra weight. Extra weight in the vehicle makes the engine work harder, decreasing fuel economy. Remove unnecessary items from the trunk and passenger cabin.
