15 MPG combined. That’s the headline figure for the 2024 Mercedes-Benz Maybach S680 4matic, and honestly, it’s almost beside the point. This isn’t a car purchased by those prioritizing fuel efficiency. The Maybach S680 exists to deliver unparalleled luxury and effortless power, and its clientele accepts the fuel consumption as a necessary byproduct of that experience. This is a vehicle for individuals who value opulence and prestige above all else, where the cost of fuel is a negligible concern compared to the statement it makes.

City and highway performance

The Maybach S680 isn’t engineered for stop-and-go city driving, and the EPA’s 12 MPG city rating reflects that. The sheer mass of the vehicle, combined with the instantaneous power delivery of the 6.0L V12, means easy acceleration, but it also demands frequent braking and thus, fuel expenditure. On the open highway, the S680 fares somewhat better, achieving 20 MPG. This is where the 9-speed automatic transmission truly shines, allowing the engine to cruise at lower RPMs, minimizing consumption while maintaining effortless passing power. However, even on the highway, the car’s size and prodigious output ultimately define its fuel efficiency.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2024 Mercedes-Benz Maybach S680 4matic is $3,850. This figure is based on driving 15,000 miles per year, with a mix of city and highway driving, and using national average fuel prices. Of course, this is merely an estimate. Actual fuel costs could vary significantly depending on individual driving habits, local fuel prices, and the proportion of city versus highway miles driven. But for someone considering a car in this price bracket, the $3,850 annual fuel bill is unlikely to be a major deterrent.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy for the Maybach S680 can fluctuate. Drivers with a heavy foot will likely see numbers closer to the city rating, even on the highway. Conversely, those who prioritize smooth, gentle acceleration and anticipate traffic flow can potentially achieve slightly better results, particularly on long highway journeys. However, it’s unrealistic to expect significant deviations from the EPA estimates. The V12 engine and the vehicle’s considerable weight will always demand a certain amount of fuel.

How it compares

Compared to other ultra-luxury vehicles, the Maybach S680’s fuel economy is generally in line with expectations for a flagship model featuring a powerful twelve-cylinder engine. Consider the Bentley Flying Spur with its W12 engine, which clocks in at a similar 15 MPG combined. Even a more fuel-conscious competitor like the Rolls-Royce Ghost, while offering a degree of “efficiency,” still only achieves around 14 MPG combined in real-world use. Those seeking better fuel economy within the Mercedes-Benz lineup should consider the S580e plug-in hybrid, which achieves a significantly better combined MPG and electric-only range, but sacrifices the unique character of the V12. Anyone searching for all Mercedes Benz fuel economy data can easily find it online. These comparisons are almost irrelevant for the Maybach S680 buyer, who is prioritizing power, exclusivity, and comfort above all else.

Tips to maximize efficiency

While fuel economy might not be the primary concern for Maybach S680 owners, there are still a few strategies to minimize fuel consumption without sacrificing the driving experience. Smooth acceleration is key. The instantaneous torque of the V12 can be tempting, but gentle throttle inputs will avoid unnecessary fuel burn. Anticipating traffic flow and maintaining a consistent speed can also make a difference.

Use the car’s driving modes. The “Comfort” mode will prioritize efficiency by optimizing throttle response and transmission behavior. While “Sport” mode provides a more engaging experience, it does so at the expense of fuel economy. Choosing the appropriate mode for the driving conditions can help extract the most mileage possible.

Ensure proper tire inflation. Underinflated tires increase rolling resistance, which negatively impacts fuel economy. Regularly check tire pressure and maintain the recommended levels specified on the door sticker. This simple step can improve fuel consumption and also enhance tire life.

Avoid unnecessary idling. Letting the engine idle for extended periods consumes fuel without covering any distance. If you anticipate stopping for more than a minute or two, it’s best to turn off the engine. Modern engines, including the Maybach’s V12, are designed to restart quickly and efficiently, minimizing any potential inconvenience.

Consider shorter trips in a different vehicle. While the S680 excels on long journeys, using a smaller, more efficient vehicle for quick errands or city commuting can significantly reduce overall fuel consumption. The mileage numbers for MAYBACH MPG across all years underscores the importance of driving behavior.
