15 MPG combined. That’s the fuel economy figure for the 2022 Mercedes-Benz Maybach S680 4matic, and it’s about what you’d expect. This isn’t a car for those who want lower fuel costs or are financially frugal. It’s a statement, a rolling palace powered by a majestic 6.0L V12, intended for those who prioritize ultimate luxury and effortless power. For the target demographic, CEOs, dignitaries, and those for whom money is truly no object, fuel economy is a tertiary concern, behind prestige, comfort, and exclusivity. They’re buying an experience, not transportation.

City and highway performance

The EPA estimates the Maybach S680 achieves 12 MPG in the city and 21 MPG on the highway. That urban figure reflects the engine’s thirst when navigating stop-and-go traffic, a common scenario since many examples will spend significant time chauffeuring occupants through congested urban environments. The highway number isn’t terrible, relatively speaking. The long-legged gearing of the 9-speed automatic transmission and the engine’s inherent low-revving nature allows for reasonable fuel consumption when cruising at speed. Even on the open road, the temptation to unleash the V12’s power is ever-present, and indulging will certainly impact fuel efficiency.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2022 Mercedes-Benz Maybach S680 is estimated at $3,850. This figure is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, using national average fuel prices, which fluctuate. Consider this annual fuel expense within the context of ownership. We’re talking about a purchase price exceeding $200,000, plus insurance, maintenance, and the likely addition of custom features. The fuel bill, while significant to most drivers, is unlikely to deter a Maybach S680 buyer.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy will vary. Factors such as driving style, traffic conditions, and even the quality of fuel used can all influence the actual MPG. Someone who enjoys the thrill of the V12 and drives predominantly in the city may struggle to achieve even the EPA’s 12 MPG city rating. Conversely, a chauffeur who adopts a more measured approach primarily on the highway might slightly exceed the EPA’s 21 MPG highway figure. However, regardless of driving habits, expecting to consistently match or beat the EPA combined rating is optimistic.

How it compares

Compared to other ultra-luxury vehicles, the Maybach S680’s fuel economy sits predictably at the lower end. For example, the Rolls-Royce Phantom, with its similarly sized V12 engine, achieves an EPA-estimated 14 MPG combined. Even the Bentley Flying Spur, while offering V8 and hybrid powertrain options alongside the W12, struggles to break into the 20s, with the W12 variant matching the Maybach at 15 MPG combined. A buyer cross-shopping cars in this segment isn’t prioritizing efficiency, but it’s still useful to check all Mercedes Benz fuel economy data to understand the context of this model’s consumption. The MAYBACH MPG across all years are consistently low, due to the brand’s focus on performance and luxury.

Tips to maximize efficiency

While fuel economy might not be the primary concern, there are ways to reduce consumption, even in a V12-powered Maybach. Gentle acceleration and smooth braking are key. Avoid unnecessary hard launches and try to anticipate traffic flow to minimize stop-and-go driving. The less you summon all 621 horsepower, the better your fuel efficiency will be.

Ensure the tires are properly inflated. Underinflated tires increase rolling resistance, which forces the engine to work harder, burning more fuel. Check the tire pressure regularly and maintain it at the recommended level found on the driver’s side doorjamb.

Minimize unnecessary weight in the vehicle. While a few personal belongings won’t make a noticeable difference, avoid carrying around excessive cargo that adds to the vehicle’s overall weight. The V12 can handle it, but it will impact your MPG, especially if you are transporting a valuable passenger.

Consider using “Comfort” or “Eco” mode, if equipped. These drive modes often adjust the engine and transmission settings to prioritize fuel efficiency over performance, although they might slightly dampen the car’s responsiveness. Regardless, they’ll help improve fuel consumption.
