C55

C55 is a designation used across multiple domains to identify models, routes, or product codes. In popular usage, the best-known reference is in automobiles, where C55 variants denote performance-oriented interpretations of standard C-class lineups.

Mercedes-Benz C55 AMG was a high‑performance version of the C-Class developed by AMG, the performance division of Mercedes-Benz. Produced in the mid-2000s, it featured a larger V8 powerplant, revised suspension and braking systems, and distinctive styling cues compared with the standard C-Class.

In other contexts, C55 is used as a road or route designation in various national or regional networks. Such alphanumeric codes typically indicate a local or connector road within a county or state system, and the exact meaning depends on the jurisdiction.

In consumer electronics and industrial products, C55 appears as a model, part, or revision number. Examples include cameras, printers, or microcontroller families where the C55 code helps identify a specific generation or variant.

Because C55 spans different fields, interpretation relies on surrounding information such as the product, location, or industry context.
