The Mercedes-Benz S-Class Long (V220) AMG S 55, produced from 2001 to 2002, represented a high-performance variant of the already luxurious W220 S-Class. Positioned as a flagship sedan, the AMG S 55 offered a significant increase in power and performance compared to the standard S-Class models, targeting buyers who desired both opulent comfort and exhilarating driving dynamics. The “Long” designation indicates an extended wheelbase, providing increased rear passenger legroom, a feature particularly popular in markets outside of North America where chauffeur-driven luxury was common. This model occupied the top tier of the V220 range, sitting above the S430 and S500 in terms of both price and performance.

Powertrain & Engine Architecture
The heart of the AMG S 55 was the M113 E 55, a 5.4-liter naturally aspirated V8 engine. This engine was a significant departure from the standard S-Class engines, featuring a larger displacement and a more aggressive camshaft profile. The M113 utilized a three-valve per cylinder design (two intake, one exhaust) and a multi-port fuel injection system. The engine’s robust construction and relatively simple design (for its performance level) contributed to its long-term reliability. Power was transmitted to the rear wheels via the 5G-TRONIC automatic transmission, a five-speed unit known for its smooth shifts and adaptability. This transmission was specifically tuned by AMG to handle the increased torque output of the V8 engine. The 5G-TRONIC offered a manual shift mode, allowing drivers some control over gear selection, though it wasn’t as responsive as later, more advanced automatic transmissions.
Driving Characteristics
The AMG S 55 delivered a markedly different driving experience compared to the standard S-Class models. The increased horsepower and torque resulted in significantly quicker acceleration – 0 to 60 mph in approximately 5.7 seconds and a governed top speed of 155 mph. While not a dedicated sports car, the AMG S 55 offered a compelling blend of performance and comfort. The 5G-TRONIC transmission, while smooth, could feel slightly hesitant during quick downshifts. The suspension was tuned to provide a firmer ride than the standard S-Class, improving handling and body control, but without sacrificing too much in terms of overall comfort. The long wheelbase contributed to a stable and planted feel, especially at highway speeds.
Equipment & Trim Levels
The AMG S 55 came standard with a comprehensive list of luxury features, befitting its flagship status. Interior appointments included premium leather upholstery, wood trim, and power-adjustable heated and ventilated front seats. Standard equipment also included a premium sound system, automatic climate control, and a sunroof. Optional extras included rear seat entertainment, massaging seats, and a variety of exterior styling enhancements, such as AMG-specific wheels and body styling elements. The extended wheelbase “Long” version offered significantly more rear legroom, making it a popular choice for those who frequently traveled with passengers or were chauffeured.
Chassis & Braking
The chassis of the AMG S 55 was largely similar to that of the standard S-Class, featuring a fully independent suspension with multi-link front and rear designs. However, the AMG variant benefited from stiffer springs and dampers, as well as a larger stabilizer bar, to improve handling and reduce body roll. Braking duties were handled by ventilated disc brakes on all four wheels, coupled with an Anti-lock Braking System (ABS). The braking system was upgraded compared to the standard S-Class to cope with the increased performance and weight of the AMG model.
Market Reception & Comparison
The AMG S 55 was generally well-received by automotive critics, who praised its powerful engine, luxurious interior, and comfortable ride. However, some reviewers noted that the 5G-TRONIC transmission could feel a bit dated compared to newer automatic transmissions. Compared to the standard S430 and S500 models, the AMG S 55 offered a substantial performance upgrade, but at a significant price premium. Fuel economy was also considerably lower, reflecting the larger engine and increased power output. The AMG S 55 competed with other high-performance luxury sedans, such as the BMW 750iL and the Jaguar XJ Super V8.
Legacy
The M113 engine, found in the AMG S 55, is known for its durability and relatively straightforward maintenance. While not immune to age-related issues, these engines generally hold up well with proper care. Today, the AMG S 55 represents a compelling value in the used luxury car market, offering a significant amount of performance and luxury for the price. However, potential buyers should be aware of the higher maintenance costs associated with a high-performance vehicle of this age, including potential issues with the air suspension system and electronic components. The AMG S 55 remains a desirable and respected example of early 2000s German engineering, representing a sweet spot between classic luxury and modern performance.
