In the late 1980s, Porsche faced a unique challenge: building a car that could meet stringent noise regulations without sacrificing performance. To achieve this, the company created a one-off prototype based on the 928 model.
The resulting vehicle was a far cry from a sleek sports car, with a body wrapped in cotton wool, repositioned engine components, and a makeshift exhaust system. But despite its unusual appearance, this 928 served a vital purpose: testing and refining noise reduction technologies.
The car’s peculiar design features, such as bulging wheel arches and a large intake barrel, were functional rather than aesthetic. They allowed engineers to test various tire compounds and wheel configurations, crucial for minimizing noise levels.
The 928’s powerful engine and low-rpm torque made it an ideal candidate for this task, unlike other Porsche models like the 911, 924, and 944, which were ruled out due to their noise profiles.
This unusual prototype played a critical role in helping Porsche develop quieter cars, a necessity for meeting increasingly stringent regulations. After years of service, it now resides at the Porsche Museum in Stuttgart, a testament to the company’s commitment to innovation and performance.
Despite its unconventional appearance, this 928 embodies the “form follows function” principle, a reminder that sometimes, functionality takes precedence over aesthetics.
