Generations and History of Mercedes-Benz 500 SEL
First Generation (W126)
The first generation of the 500 SEL was introduced as part of the W126 S-Class lineup, which debuted in September 1979. This model was a significant step forward in automotive design and technology, pioneering features such as airbags and a more aerodynamic body. The long-wheelbase “SEL” version provided an additional 140 mm of legroom for rear passengers. The initial 5.0-liter V8 engine was an all-alloy unit that offered improved performance and fuel economy over its predecessor. The design, penned by Bruno Sacco, was both elegant and timeless, characterized by its clean lines and integrated plastic-coated bumpers.
Second Generation (W140)
The W140 generation, launched in 1991, represented a new era of luxury and technological advancement for the S-Class. The 500 SEL of this generation was a larger and more imposing vehicle, often dubbed the “last over-engineered Mercedes.” It featured a new 5.0-liter V8 engine with four valves per cylinder, significantly boosting power output. The W140 introduced a host of innovations, including double-paned soundproofed glass, a closing aid for the doors and trunk, and an advanced climate control system. Its design was a departure from the W126, with a more substantial and muscular stance that conveyed a sense of ultimate luxury and safety.
Latest Generation
The Mercedes-Benz 500 SEL designation was discontinued after the W140 generation. The S-Class has continued to evolve through subsequent generations, with the “500” moniker now typically associated with models like the S 500, which continue the legacy of a V8-powered luxury sedan. These modern iterations are equipped with the latest in automotive technology, including advanced driver-assistance systems, sophisticated infotainment, and hybrid powertrain options. While the 500 SEL is no longer in production, its influence can be seen in the ongoing commitment to luxury, performance, and innovation in the current S-Class lineup.

This allowed the large sedan to accelerate from 0 to 100 km/h in approximately 7.5 to 8.1 seconds, with a top speed of around 230 km/h. The W140 generation introduced the more advanced M119 5.0-liter V8 with dual overhead camshafts and four valves per cylinder. This engine produced a formidable 322 horsepower, enabling the heavier car to reach 100 km/h in about 7 seconds and an electronically limited top speed of 250 km/h. Across both generations, the 500 SEL was praised for its serene and comfortable ride quality, thanks to its sophisticated suspension system.
