The Mercedes-Benz S 580e Long (V223) represents the pinnacle of luxury and efficiency in the flagship S-Class range. Introduced in November 2021 as part of the V223 generation, this plug-in hybrid variant combines a powerful inline-six engine with an electric motor, offering a compelling blend of performance and reduced emissions. Production is expected to continue through 2026. The “Long” designation indicates an extended wheelbase, providing enhanced rear passenger space, a key feature for markets prioritizing chauffeur-driven luxury. This model is primarily targeted towards buyers seeking a sophisticated, technologically advanced sedan with the flexibility of electric driving.
Powertrain & Engine Architecture
The S 580e’s powertrain centers around the M 256.930 3.0-liter inline-six cylinder engine, featuring a twin-scroll turbocharger and direct fuel injection. This engine produces 367 horsepower and 500 Nm (368.78 lb.-ft.) of torque. Integrated with this is a powerful electric motor, delivering 150 horsepower and 440 Nm (324.53 lb.-ft.) of torque. The combined system output reaches a substantial 510 horsepower and 750 Nm (553.17 lb.-ft.). The engine utilizes a high compression ratio of 10.5:1 and a sophisticated DOHC valvetrain. The 28.6 kWh lithium-ion battery pack, located under the trunk floor, provides an all-electric range of 93-107 km (57.79 – 66.49 mi) according to WLTP standards. Power is delivered to all four wheels via Mercedes-Benz’s 9G-TRONIC nine-speed automatic transmission and the 4MATIC all-wheel-drive system.
Driving Characteristics
The S 580e offers a remarkably refined driving experience. In electric mode, the car provides near-silent acceleration and smooth, instant torque. When the combustion engine engages, the transition is seamless. The 9G-TRONIC transmission is tuned for comfort and efficiency, with gear changes being almost imperceptible. While not as overtly sporty as some S-Class variants, the 510 hp system output provides ample power for effortless cruising and confident overtaking. The all-wheel-drive system ensures excellent traction in various weather conditions. Compared to the S 580 with the standard V8 engine, the 580e prioritizes efficiency and offers a different power delivery character, with the electric motor providing immediate torque at low speeds.
Equipment & Trim Levels
The S 580e Long typically comes standard with a comprehensive suite of luxury features, including leather upholstery, heated and ventilated front and rear seats, a Burmester surround sound system, and the latest generation of Mercedes-Benz’s MBUX infotainment system with a large touchscreen display. Air suspension is standard, providing a supremely comfortable ride. Optional extras include a rear-seat entertainment system, massaging seats, and a head-up display. The interior trim options range from wood veneers to aluminum accents, allowing for a degree of personalization. The “Long” wheelbase adds significantly to rear passenger legroom, making it a preferred choice for those who frequently travel with passengers.
Chassis & Braking
The S 580e Long utilizes an independent multi-link suspension system at both the front and rear, coupled with Mercedes-Benz’s AIRMATIC air suspension. This combination delivers exceptional ride quality and handling. Ventilated disc brakes are fitted on all four wheels, providing strong and consistent stopping power. The car is equipped with ABS, Electronic Stability Program (ESP), and a range of advanced driver-assistance systems. The steering is electric power-assisted, offering precise and responsive control. The long wheelbase contributes to increased stability, particularly at higher speeds.
Market Reception & Comparison
The S 580e Long has been generally well-received by automotive critics, praised for its luxurious interior, smooth ride, and impressive fuel efficiency. The plug-in hybrid powertrain allows for significant reductions in fuel consumption and emissions, particularly for drivers who frequently commute short distances and can take advantage of electric-only driving. Compared to the S 580 with the traditional V8 engine, the 580e offers a more environmentally friendly option without sacrificing significant performance. However, the larger battery pack does reduce trunk space compared to non-hybrid S-Class models. Reliability reports are still emerging, but Mercedes-Benz’s reputation for build quality and engineering suggests a high level of dependability.
Legacy
The S 580e Long represents a significant step towards electrification in the luxury sedan segment. Its combination of a powerful engine, electric motor, and advanced technology sets a new standard for efficiency and refinement. As the automotive industry continues to shift towards electric vehicles, the S 580e is likely to be remembered as a pivotal model in Mercedes-Benz’s transition to a more sustainable future. On the used car market, these models are expected to hold their value well, particularly as demand for plug-in hybrids continues to grow. The longevity of the battery pack will be a key factor in determining the long-term value and desirability of these vehicles.
