16 MPG combined, that’s the fuel economy for the 2020 BMW M760i xDrive. Some buyers of this powerful, luxurious car may shrug at that number. This car isn’t just basic transportation; it’s a statement, a fast mobile office. Fuel economy is simply what you pay to experience a smooth 6.6-liter V12 engine.

City and highway performance

The EPA’s city fuel economy estimate for the M760i xDrive is a low 13 MPG. This is due to stop-and-go traffic, the car’s weight, and the natural inefficiencies of a large engine. The highway rating is better, at 20 MPG. While not like a Prius, achieving 20 MPG on the highway is possible if you avoid using the V12’s power often. The eight-speed automatic transmission (S8), though well-calibrated, still loses some efficiency compared to a manual, but a manual transmission would feel out of place in this car.

Annual fuel cost

The EPA says the estimated annual fuel cost for the 2020 BMW M760i xDrive is $3,600. This assumes 15,000 miles per year and national average fuel prices. It’s a lot of money to spend on gas, but probably not for the people who buy this car. The calculation assumes 15,000 miles driven each year. Some owners who have the car as part of a collection may drive it less. Others might drive it more, increasing the annual fuel cost.

Real-world expectations

Don’t expect to always get 16 MPG in normal driving. Quick acceleration, frequent short trips, and idling will all lower fuel economy. To save gas, drive gently and avoid traffic. Owners who want to maximize efficiency should check all Bmw fuel economy data.

How it compares

The M760i’s fuel economy is the worst in the large luxury sedan class. A Mercedes-Benz S560 4Matic, with its 4.0-liter V8, gets a slightly better 19 MPG combined. The Porsche Panamera Turbo S E-Hybrid achieves a much higher combined fuel economy because it has a plug-in hybrid system, despite its power and all-wheel drive. But, none offer a smooth V12. Some ultra-luxury sedans prioritize less gas. The M760I MPG across all years has always been low. The Alpina B7 has a similar market position and performance as the M760i, and often has slightly better real-world fuel economy because of tuning and driving style.

Tips to maximize efficiency

Watch traffic and keep a smooth, consistent speed. Avoid accelerating quickly and braking hard, as this wastes fuel, especially in a heavy and powerful car like the M760i. Use the gas pedal in a gentle and controlled manner to reduce stress on the engine and transmission. This can save money at the pump.

Make sure your tires have the correct amount of air. Tires with low air pressure increase rolling resistance, which reduces fuel economy. Check your tires regularly and inflate them to the recommended pressure found on the door or in the owner’s manual.

Don’t let the car idle, especially when the engine is cold. Modern engines don’t need to warm up for a long time. Idling wastes fuel. If you’ll be stopped for more than a minute or two, turn off the engine.

On long highway trips, consider using the car’s adaptive cruise control system. This system helps keep a consistent speed and distance from other cars, reducing unnecessary acceleration and braking, which can improve fuel economy.

Decrease the weight in the car by removing any unnecessary items from the trunk or passenger area. Carrying extra weight reduces fuel economy, so remove anything that’s not needed to see some small gains.
