In 1967, the automotive world was buzzing with excitement over the upcoming introduction of the Bayer K67, a groundbreaking all-plastic prototype auto chassis. Developed by Farbenfabriken Bayer AG and set to be unveiled at the 1968 Design Engineering Show in Chicago, the K67 was set to revolutionize automotive design as we know it.
From the official press release, it was clear that this new chassis was not just a simple substitution of metal for plastic. The combination of high-strength plastic sheeting materials with high-density rigid urethane foam as the core section was a game-changer. Mobay Chemical Company in Pittsburgh, the company behind the K67, had created a chassis that offered a high strength-to-weight ratio, low tooling and production costs, and almost unlimited flexibility in materials and processing methods.
As automotive design engineers got a glimpse of the K67, it was immediately apparent that this was not just a novelty project. The frame was going out, and the future of automotive engineering was becoming clearer. The K67 was not just an experiment; it was a statement.
While the auto industry had dabbled in using engineering plastics before, the K67 was on a different level. All-plastic body shells had been around since the 1950s, but the K67 took things to a whole new level. It wasn't just about substituting plastic for metal; it was about redefining what was possible in automotive design.
As we look back on the 1967 Bayer K67, it's clear that this prototype was a true pioneer in the industry. It may not have gone into commercial production, but its impact was felt far beyond the Design Engineering Show in Chicago. The K67 showed us what was possible when we pushed the boundaries of traditional automotive design, and its legacy lives on in the innovations we see in cars today.
