Mercedes has filed trademarks in Canada and other counties for a new two-digit naming scheme for its vehicles. This comes after the automaker revamped its nomenclature just a few years ago. The proposed new system dumps the three-digit system that corresponded to non-AMG models. Now all Mercedes models will have a two-digit name. Mercedes will use numeric names ending in 0 as markers for standard vehicles, while Mercedes-AMG models will end in 3.
