21 MPG combined. That’s the figure associated with the 2024 Mercedes-Benz S580 4Matic Maybach, and while it might raise eyebrows amongst economy-minded shoppers, it’s largely irrelevant to the target demographic for this ultra-luxury sedan. This isn’t a car bought for its fuel consumption; it’s a statement, a mobile sanctuary, and a triumph of comfort and engineering. The S580 Maybach exists for those who prioritize quiet power and opulent lavishness, and for them, fuel cost is a minor concern.

City and highway performance

The EPA estimates provide a more detailed view of the S580 Maybach’s fuel consumption. The city rating of 18 MPG reflects the stop-and-go realities of urban driving, where the 4.0-liter twin-turbo V8 is frequently tasked with overcoming inertia. This is where the engine’s size and forced induction make their presence felt. Out on the open road, the highway rating of 26 MPG demonstrates the engine’s ability to cruise efficiently. The smooth-shifting 9-speed automatic transmission helps by keeping the engine in its most efficient RPM range. These numbers are benchmarks obtained under standardized test conditions, and your driving and road conditions will affect these numbers.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2024 Mercedes-Benz S580 4Matic Maybach at $2,750. This figure is based on driving 15,000 miles per year and using national average fuel prices. In practice, the actual fuel expenditure could be higher or lower depending on individual driving habits, local fuel prices, and the ratio of city versus highway miles driven. For the demographic considering a Maybach, this expense is a relatively small price to pay for the privilege of experiencing this level of luxury, comfort, and performance.

Real-world expectations

Owners of the S580 Maybach likely won’t be obsessively tracking their fuel mileage. Their driving patterns often involve a mix of chauffeur-driven city commutes and longer highway journeys. Frequent hard acceleration will reduce MPG figures. Driving style dominates the MPG figure in all vehicles, and that is a fact to remember.

How it compares

Compared to other vehicles in the ultra-luxury sedan segment, the S580 Maybach’s fuel economy falls within the expected range. The Bentley Flying Spur, with its W12 engine, achieves around 15 MPG combined, making it less efficient. The Rolls-Royce Ghost posts similar figures to the Bentley. These comparisons are important because Maybach buyers may not be overly concerned with fuel costs, but they are aware of the nuances in the market. They are likely comparing the overall ownership experience, rather than scrutinizing MPG numbers in isolation. You can view all Mercedes Benz fuel economy data to consider other models.

Tips to maximize efficiency

While fuel economy might not be the primary goal of a Maybach owner, some strategies will help optimize efficiency without sacrificing enjoyment. Avoid hard acceleration. Gentle acceleration allows turbos to develop boost efficiently so you stay out of secondary fuel enrichment maps contained within the engine’s ECU. Drive it gently.

Use the car’s driving modes. The “Comfort” or “Eco” modes, if available, will prioritize fuel efficiency by adjusting the throttle response and shift points. The differences are small, but with consistent use your wallet will thank you.

Ensure the tires are properly inflated. Correct tire pressure reduces rolling resistance and improves fuel economy. This is even more important in heavier vehicles like the Maybach. Check it regularly.

Minimize unnecessary weight. Avoid carrying excessive cargo in the trunk, as this increases the vehicle’s load and reduces fuel efficiency. Every little bit matters.
