The 2024 Mercedes-Benz EQS 680 4matic Maybach (SUV) achieves a combined EPA rating of 76 MPG, a figure that requires immediate context. This isn’t your average SUV trying to save fuel. It’s a rolling palace of opulence, draped in Maybach badging and engineered for a clientele where range anxiety is a far greater concern than filling up. Efficiency, in this rarified air, is measured against the extravagant baseline of ultra-luxury vehicles.

City and highway performance

Those 76 MPG are further broken down into 75 MPG in the city and 77 MPG on the highway. These aren’t the numbers that will sway a Maybach buyer, but they are relevant to the driving experience. The near-identical figures point to the electric powertrain’s smooth power delivery. Acceleration is effortless, and the regenerative braking system is expertly calibrated. The EQS 680 Maybach SUV moves with a grace that belies its substantial size, whether navigating congested city streets or cruising at high speeds.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2024 Mercedes-Benz EQS 680 4matic Maybach (SUV) is $1,000. This figure is based on driving 15,000 miles per year and using national average electricity prices. While hardly inexpensive, it’s a rounding error compared to the vehicle’s six-figure price tag. For context, consider the operating costs of traditional, gas-powered luxury SUVs of similar size and performance. Many owners will likely plug in at home overnight, further minimizing the impact of charging costs while ensuring a full “tank” every morning.

Real-world expectations

The official EPA numbers are a useful benchmark, but real-world MPG in electric vehicles depends heavily on driving style, ambient temperature, and use of features like climate control. Expect the 76 MPG combined figure to fluctuate. Aggressive acceleration will deplete the battery faster, as will consistent high-speed driving. Extremely cold weather can also reduce range, as the battery requires energy to maintain optimal operating temperature. However, for the typical EQS Maybach SUV owner, who likely has multiple vehicles and uses this one primarily for shorter trips or chauffeured experiences, the practical impact of these fluctuations will be minimal.

How it compares

Compared to its gasoline-powered counterparts, the EQS 680 Maybach SUV easily surpasses their fuel economy. The Bentley Bentayga V8, for instance, manages only 17 MPG combined. Even the hybrid versions of other large luxury SUVs fall short. The BMW X5 xDrive50e, a plug-in hybrid, achieves 58 MPGe combined, illustrating the EQS offering a clear advantage. While the all-electric Rolls-Royce Spectre doesn’t have official EPA ratings, early estimates suggest it will land near or below the EQS Maybach SUV’s figures. For buyers considering an all-electric luxury experience, the efficiency of the EQS 680 4matic Maybach SUV is a distinct advantage over most traditional options.

Tips to maximize efficiency

Pre-conditioning the cabin while the vehicle is plugged in can significantly extend range, especially in cold weather. This heats or cools the interior using grid power, rather than drawing energy from the battery once you’re on the road. The Mercedes-Benz User Experience (MBUX) system offers detailed energy consumption information, including driving efficiency tips based on your route and driving style. Reviewing this data regularly can help you identify areas for improvement.

Gentle acceleration and smooth braking are key to maximizing range in any electric vehicle. Avoid hard starts and stops, and use the regenerative braking system to recapture energy. The Maybach SUV offers adjustable regeneration levels; experiment to find the setting that best suits your driving style and maximizes efficiency without sacrificing comfort.

Tire pressure plays a surprisingly large role in fuel efficiency. Ensure your tires are properly inflated to the recommended pressure listed on the driver’s side doorjamb. Underinflated tires increase rolling resistance, forcing the motor to work harder and reducing range.

Consider using the “Eco” driving mode for everyday commuting or longer trips. This mode typically reduces throttle response and optimizes energy consumption, prioritizing efficiency over outright performance. The difference may be small, but it can add up on a longer journey.

The Mercedes-Benz EQS 680 4matic Maybach (SUV) exists in a world where price and fuel efficiency are secondary to comfort, technology, and exclusivity. But even within that context, its electric powertrain delivers a blend of performance and relative efficiency, offering a guilt-free (or at least, guilt-reduced) experience for those who demand the very best.
