14 MPG combined is a statement. The 2023 Mercedes-Benz Maybach S680 4matic 6.0L 12-cyl prioritizes effortless power, opulent luxury, and a driving experience that borders on surreal, over fuel efficiency. Owners seek an unparalleled level of performance and luxury and accept the fuel consumption. This is not a machine designed for penny-pinching, it’s a rolling sanctuary of bespoke craftsmanship and raw V12 force.

City and highway performance

The EPA estimates of 12 MPG in the city and 20 MPG on the highway accurately reflect the fuel consumption of a 6.0-liter, twelve-cylinder engine moving nearly three tons of handcrafted German engineering. In urban environments, the Maybach S680’s power is readily available, allowing it to navigate stop-and-go traffic with a muted growl from its exhaust. The highway figure, while still modest, demonstrates the engine’s ability to cruise comfortably at higher speeds, delivering a smooth and refined experience. The focus is on the engine’s unburdened nature, barely working even at high cruising speeds.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Mercedes-Benz Maybach S680 4matic at $4,150. This figure is based on driving 15,000 miles per year, with an assumed even split between city and highway driving, using the national average fuel price at the time of calculation. This number contrasts most vehicles and highlights owning a V12-powered ultra-luxury sedan. The cost results from the engine’s size and the power it produces. For the typical Maybach owner, this fuel expenditure is likely a small fraction of the overall cost of ownership, which includes vehicle price, insurance, maintenance, and depreciation.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy for the Maybach S680 can vary based on driving style, traffic conditions, and fuel quality. Aggressive acceleration and frequent hard braking will lower fuel efficiency, particularly in the city. However, gentle acceleration and consistent speed on the highway can improve fuel economy, potentially bringing it closer to the EPA estimate. Additional weight from optional features or passengers can also influence fuel consumption. Expect the posted numbers with a possible variance given the driving dynamics of the primary user.

How it compares

The Maybach S680’s fuel economy comparing it to other ultra-luxury sedans is predictably low. The Rolls-Royce Phantom, with its V12 engine, achieves around 12 MPG combined. The Bentley Flying Spur, equipped with a V8 engine, manages a slightly better 19 MPG combined, but the V12-powered Flying Spur returns nearly identical mileage to the Maybach. Electric options also differ significantly. The BMW i7, a fully electric luxury sedan, achieves the equivalent of 87 MPG combined, a contrast in efficiency, but also a different driving experience. These comparisons focus on understanding the trade-offs in prioritizing performance and luxury.

Tips to maximize efficiency

Although fuel economy is likely not a primary concern for Maybach S680 owners, some strategies can help minimize fuel consumption. Gentle acceleration and smooth braking can reduce fuel usage, especially in city driving. Avoid sudden bursts of speed and anticipate traffic flow to minimize unnecessary braking.

Maintaining proper tire inflation is critical for fuel economy. Underinflated tires increase rolling resistance, requiring the engine to work harder and consume more fuel. Regularly check tire pressure to ensure it meets the manufacturer’s recommendations.

Avoid prolonged idling. When stopped for more than a minute, it’s generally more fuel-efficient to turn off the engine and restart it when ready to proceed. Modern engine technology makes restarting quick and easy, with minimal wear and tear.

Use cruise control on the highway to maintain a consistent speed and minimize unnecessary acceleration. Cruise control helps the engine operate at its most efficient point, improving fuel economy on long drives. Remember to use cruise control with an awareness of road conditions.

Consider using the car’s driving mode selector. If equipped with an “Eco” or “Comfort” mode, use it to optimize engine performance for better fuel efficiency. Be mindful of how the performance will be slightly decreased and adjust your driving accordingly.
