The 1972 Mercedes-Benz W114 and W115, collectively known as the "Stroke Eight" models, represent a significant chapter in the history of the German automaker. These mid-size sedans, launched in 1968 and produced until 1976, were the first Mercedes-Benz models to feature a completely redesigned body since the 1950s. They introduced a new level of comfort, safety, and refinement, setting a new standard for the luxury car segment. The W114 and W115 models were available in a variety of body styles, including two- and four-door sedans, coupes, and even a station wagon. The 2.2-liter and 2.5-liter inline-six engines, paired with robust four-speed manual or three-speed automatic transmissions, provided a balance of power and fuel efficiency. Notably, the W114 introduced the first use of crumple zones in a Mercedes-Benz passenger car, significantly contributing to its impressive safety record.

The 1972 models built upon the success of their predecessors, incorporating minor refinements and enhancements. These included updated interior trim, revised suspension tuning to deliver a smoother ride, and the introduction of new optional features like power steering and air conditioning. The W114 and W115 continued to be highly regarded for their robust construction, excellent handling, and luxurious appointments. While the original models were not originally intended for export, their sales success led to their eventual release in markets like the United States and Canada. Today, the W114 and W115 models are sought-after by classic car enthusiasts for their timeless design, enduring reliability, and comfortable ride. They are a testament to the engineering excellence and dedication to quality that has become synonymous with the Mercedes-Benz brand.
