The Mercedes-Benz S 580e Long, launched in 2021, builds upon the established reputation of the S-Class as a benchmark for automotive luxury. It represents Mercedes-Benz’s commitment to electrification, offering a sophisticated plug-in hybrid powertrain within the flagship sedan. The V223 generation S-Class, and specifically the S 580e, is built on the M117 platform, incorporating advanced technologies in areas such as driver assistance, infotainment, and chassis control. The extended wheelbase “Long” variant is particularly popular in markets like China and other regions where rear passenger comfort is prioritized.
Powertrain & Engine Architecture
At the heart of the S 580e lies a 3.0-liter inline-six cylinder engine, designated M 256.930. This engine utilizes direct injection and is augmented by a twin-scroll turbocharger and intercooler, producing 367 horsepower and 500 Nm (368.78 lb.-ft.) of torque. The engine is paired with a 150 hp electric motor integrated between the engine and the 9G-TRONIC nine-speed automatic transmission. The combined system output reaches 510 hp and 750 Nm (553.17 lb.-ft.) of torque. The 28.6 kWh (21.5 kWh usable) lithium-ion battery pack is located under the trunk floor, providing an all-electric range of 94-113 km (58.41 – 70.21 mi) according to WLTP standards. The engine management system seamlessly blends power from both sources, optimizing for efficiency or performance as needed. The 9G-TRONIC transmission is specifically calibrated for the hybrid powertrain, offering smooth and efficient gear changes.
Driving Characteristics
The S 580e delivers a remarkably refined driving experience. In electric mode, the car operates silently and smoothly, providing instant torque for effortless acceleration. Switching to hybrid mode allows the combustion engine to assist during more demanding situations, such as highway overtaking or climbing hills. The 9G-TRONIC transmission’s gear ratios are optimized for both fuel efficiency and responsive performance. While the S 580e is heavier than its purely gasoline-powered counterparts due to the battery pack, the combined power output ensures brisk acceleration – 0-60 mph in approximately 4.9 seconds. The air suspension provides a supremely comfortable ride, effectively isolating passengers from road imperfections. Compared to the S 500, the S 580e offers similar performance with the added benefit of electric-only driving capability.
Equipment & Trim Levels
The S 580e Long comes standard with a comprehensive suite of luxury features. Interior appointments include premium leather upholstery, wood trim, and ambient lighting. Standard technology includes the MBUX infotainment system with a large touchscreen display, a digital instrument cluster, and advanced driver-assistance systems such as adaptive cruise control, lane-keeping assist, and automatic emergency braking. Optional extras include rear-seat entertainment systems, massaging seats, a Burmester surround sound system, and a head-up display. The “Long” wheelbase provides significantly more rear legroom, enhancing the comfort of rear passengers. Trim levels typically offer variations in interior color schemes and exterior styling details.
Chassis & Braking
The S 580e Long features an independent multi-link suspension at both the front and rear, coupled with Mercedes-Benz’s AIRMATIC air suspension system. This combination provides exceptional ride comfort and handling. Ventilated disc brakes are fitted on all four wheels, providing ample stopping power. The car is equipped with ABS (Anti-lock braking system) and incorporates 4-wheel steering (4WS) for improved maneuverability, particularly at low speeds. The steering system is electric power steering, offering precise and responsive control.
Market Reception & Comparison
The S 580e Long has been well-received by automotive critics, praised for its luxurious interior, advanced technology, and refined driving experience. Its plug-in hybrid powertrain offers a compelling combination of performance and efficiency, appealing to buyers seeking a more sustainable luxury vehicle. Compared to the S 500, the S 580e offers the added benefit of electric-only driving, reducing emissions and fuel consumption. However, the S 580e carries a higher price tag due to the complexity of its hybrid system. Fuel economy figures are significantly improved over non-hybrid S-Class models, particularly for drivers who frequently utilize the electric driving range.
Legacy
The S 580e Long represents a significant step in Mercedes-Benz’s electrification strategy. The powertrain, while complex, has proven to be relatively reliable in early model years. The long-term durability of the battery pack remains a key consideration for potential used car buyers. As the automotive industry shifts towards electric mobility, the S 580e Long is likely to be viewed as a transitional model, bridging the gap between traditional luxury sedans and fully electric vehicles. Its advanced technology and luxurious appointments ensure its continued desirability in the used car market.
