16 MPG combined is what you get for piloting the 2021 BMW M760i xDrive, a full-size luxury sedan propelled by a strong 6.6-liter V12 engine. This isn’t a machine for penny-pinchers; it’s for executives, dignitaries, and enthusiasts who prioritize power, prestige, and nearly silent acceleration above all else. Fuel economy is simply not a primary concern for those drawn to this particular expression of automotive excess.

City and highway performance

The M760i’s EPA ratings reveal a stark contrast between urban and open-road efficiency. In the city, expect to see around 13 MPG. This reflects the V12’s thirst during stop-and-go driving, where its considerable weight and displacement work against it.

On the highway, however, the M760i manages a respectable 20 MPG. This relative improvement comes from the eight-speed automatic transmission’s ability to settle into higher gears, allowing the engine to cruise at lower RPMs. Even at highway speeds, though, a tap of the accelerator unleashes a torrent of power, so maintaining that 20 MPG figure requires a disciplined right foot.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2021 BMW M760i xDrive is $3,600. This figure is based on driving 15,000 miles per year and using national average fuel prices. Keep in mind that premium fuel is required, further contributing to the high running costs.

While some drivers may exceed or fall short of the 15,000-mile estimate, it serves as a useful benchmark for understanding the financial commitment involved in owning a V12-powered luxury sedan. Anyone cross-shopping this vehicle should expect a substantial ongoing expense, regardless of driving habits.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy can vary significantly depending on driving style, traffic conditions, and even the type of terrain. Aggressive acceleration, frequent hard braking, and prolonged idling will all drag down the average MPG.

Conversely, a more relaxed driving style, coupled with consistent highway cruising, might yield results closer to the EPA’s 20 MPG highway rating. However, even with careful driving, achieving the advertised MPG figures consistently will be a challenge, considering the engine’s inherent power and the vehicle’s substantial weight.

How it compares

Few vehicles directly compete with the 2021 M760i in terms of its specific blend of ultra-luxury and V12 power. However, comparable vehicles exist within the luxury sedan segment. The Mercedes-AMG S63 Sedan, while not offering a V12, delivers similar performance from a twin-turbo V8 and achieves around 17 MPG combined. The Audi S8, with its twin-turbo V8, offers better efficiency at 18 MPG combined. For those willing to sacrifice some performance for improved fuel economy, the BMW 750i xDrive, with its twin-turbo V8, achieves 20 MPG combined.

The comparison matters because even within the high-performance luxury segment, there are notable differences in fuel consumption, and buyers have options if they are willing to compromise on specific features or performance characteristics.

Tips to maximize efficiency

Minimize aggressive acceleration and hard braking. The M760i’s V12 is incredibly responsive, but using its full potential frequently will decimate fuel economy. Instead, focus on smooth, gradual acceleration and anticipate traffic flow to avoid unnecessary braking.

Use the vehicle’s driving modes. The M760i offers various driving modes, including Comfort and Eco Pro. Selecting these modes can optimize engine and transmission settings for efficiency, reducing fuel consumption during everyday driving.

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 to optimize fuel efficiency and extend tire life. This is especially important on a heavy car like the M760i.

Avoid prolonged idling. Leaving the engine running while stationary wastes fuel and contributes to emissions. Turn off the engine if you anticipate being stopped for more than a minute or two. Modern engines are designed to restart quickly and efficiently, so the fuel savings can add up over time.

Keep up with scheduled maintenance. Regular maintenance, including oil changes and air filter replacements, ensures that the engine is running optimally. A well-maintained engine is a more efficient engine. Be especially mindful of the demands placed on the engine, and plan maintenance accordingly.
