The Mercedes-Benz W114/W115, affectionately known as the "Stroke Eight" due to its signature 2.5-liter straight-eight engine, marked a significant shift in the marque's mid-size offering. Debuting in 1968, these sedans were designed to replace the aging W110 "Fintail" models, offering a more modern and refined driving experience. The W114 and W115, essentially identical except for their wheelbase lengths, boasted sleek, angular lines that were a departure from the rounded forms of their predecessors. They were also significantly more spacious and comfortable, with a plush, well-appointed interior featuring a redesigned dashboard and improved ergonomics. Despite their larger dimensions, the W114/W115 cars remained remarkably agile, thanks to a combination of well-engineered suspension and a low center of gravity. Their robust construction and reputation for reliability solidified their position as true Mercedes-Benz vehicles, earning them the nickname "The Durable Ones." The W114/W115 series enjoyed a successful six-year production run, offering a diverse range of engine options, including four-cylinder, six-cylinder, and the aforementioned straight-eight. These models were available in a variety of body styles, with the most popular being the four-door sedan. A two-door coupe and a station wagon, both known as the "T" model, were also offered, further expanding the series' appeal. Despite their age, these cars continue to be highly sought after by enthusiasts today, known for their simple mechanicals and outstanding build quality. While some models were retired in 1976, the W115 continued production until 1979, with the robust 240D serving as a reliable workhorse for many years. The W114/115 series represents a watershed moment in Mercedes-Benz's history, showcasing the brand's commitment to engineering excellence and its ability to produce vehicles that are both stylish and enduring.
