The Mercedes-Benz W114/W115, affectionately nicknamed the "Stroke Eight," was a series of mid-size sedans produced by Mercedes-Benz from 1968 to 1976. Replacing the aging W110 series, the W114/W115 represented a significant leap forward for Mercedes-Benz, introducing a new level of comfort, technology, and safety. The W114, referred to as the "230," "250," and "280," featured a four-cylinder engine, while the W115, dubbed the "220," "240," "250," and "280," boasted six-cylinder powerplants. Regardless of engine size, these models shared a common, robust construction, incorporating a unibody chassis, independent suspension, and powerful disc brakes on all four wheels. The W114/W115 series was a triumph for Mercedes-Benz, setting a new standard for the mid-size sedan segment. Their reputation for reliability, durability, and comfort quickly solidified their place as a premium choice. Notable features included a spacious interior with an emphasis on driver ergonomics, a safety-focused design with crumple zones and anti-dive braking, and a smooth, refined driving experience. These cars were not only technologically advanced for their time but also exceptionally well-built, with a reputation for lasting for decades with proper care and maintenance. The W114/W115 series continued to be popular even after production ceased, with many examples still on the road today, proving their enduring appeal as both classic and reliable vehicles.
