The Mercedes-Benz Typ-116, commonly known as the W116, represents a significant chapter in the German automaker's history. Introduced in 1972 as a successor to the W108/W109 model line, the W116 ushered in a new era of luxury and refinement for Mercedes-Benz. It was the first Mercedes to feature a monocoque construction, eliminating the separate chassis and bodywork of its predecessors. This construction not only improved crashworthiness but also contributed to the car's exceptional ride quality and handling. The W116 was initially available with a range of six-cylinder petrol engines, including the iconic 280, 280E, and 300, with the larger 350 and 450 models featuring V8 engines. An exclusive 450 SEL 6.9 model even debuted with a powerful 6.9-liter V8, showcasing the car's potential for performance.

Beyond mechanical advancements, the W116 established a new standard in luxury and comfort. The spacious interior featured plush leather upholstery, wood trim, and a high level of sound insulation. The car's design, penned by Paul Bracq, was characterized by clean lines and understated elegance, a departure from the more ostentatious styling of its predecessors. The W116 offered a suite of advanced features for its time, including power steering, air conditioning, and a comprehensive instrument panel. It also became known for its durability and reliability, earning the moniker of "the bulletproof Mercedes." The W116 continued production until 1980, cementing its place as a classic and sought-after model in the Mercedes-Benz lineup, and its influence on subsequent generations of luxury sedans is undeniable.
