The lowercase "is" badge remains one of the purest expressions of German sports coupe engineering. It came from an era when factory model designations functioned as straightforward mechanical descriptions rather than consumer lifestyle labels.
Seeing that subtle chrome suffix on an original decklid still communicates a clear message to knowledgeable observers. It tells you that the car left the factory with the correct pedals, lower springs, genuine limited-slip mechanics, and an engine tuned to work harder than ordinary street machinery. Even as current models lean heavily on oversized M badges and complex digital drive modes, the classic "is" cars preserve the direct mechanical feedback that built BMW’s reputation.
