The 2018 BMW M760i xDrive, equipped with its 6.6L V12 engine, gets 16 MPG combined. No one buys this car worrying about fuel costs. They buy it for the opulent cabin, the effortless thrust of its massive engine, and the quiet confidence it exudes. Fuel economy is simply what you pay to enter a world of unmatched luxury and performance.

City and highway performance

The EPA estimates 13 MPG in the city and 20 MPG on the highway. The city figure is particularly relevant, as M760i owners often live in densely populated areas where they can’t fully use the car’s immense power. The highway MPG, while still low compared to most vehicles, reflects the engine’s ability to cruise comfortably at high speeds. This makes long-distance drives a luxurious and surprisingly tolerable affair, at least for your passengers.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 BMW M760i xDrive at $3,600. This is based on driving 15,000 miles per year and using the national average fuel price at the time of calculation. Consider this a baseline; your actual fuel expenses will vary depending on your driving habits, local fuel prices, and the proportion of city versus highway miles you typically drive.

For many owners, the M760i is a weekend or special occasion car, so the actual mileage may be lower, potentially reducing the yearly fuel bill somewhat.

Real-world expectations

Forget the EPA numbers if you’re regularly tapping into even a fraction of the M760i’s 600 horsepower you’ll see numbers well below 16 MPG. Aggressive acceleration, a habit easily formed in this car, will quickly drain the fuel tank. However, if you drive with a light foot and prioritize smooth cruising, you might approach the EPA estimates, but never expect to exceed them. Realistic M760I MPG across all years will typically fall somewhere between 12 and 18 MPG, depending on driving style and conditions.

How it compares

The M760i exists in a segment where performance often trumps fuel economy concerns. Consider the Mercedes-AMG S63, another V8-powered super-sedan with an EPA combined rating of 19 MPG. The Porsche Panamera Turbo, even with a hybrid powertrain, only manages around 22 MPG combined in its most potent configurations. These competitors highlight the trade-off in owning a high-performance luxury sedan: efficiency often takes a back seat to outright power and exclusivity. For owners looking to see all BMW fuel economy data, comparing it to the M760i is eye-opening.

Tips to maximize efficiency

Minimize aggressive acceleration. The V12 is incredibly responsive, but each hard launch takes a significant toll on fuel consumption. Smooth, gradual acceleration will dramatically improve your mileage, even if it means slightly taming the beast within.

Use the Eco Pro driving mode. While it somewhat dulls throttle response, it optimizes various vehicle settings to promote fuel efficiency. It won’t transform the M760i into a Prius, but it can make a noticeable difference, especially on longer highway drives.

Ensure proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Regularly check and maintain the recommended tire pressure for optimal efficiency and handling.

Reduce unnecessary weight. Every extra pound onboard requires more energy to move the car. Avoid carrying unnecessary cargo in the trunk and keep the cabin clutter-free to minimize fuel consumption.
