It appears as if Mercedes-Benz is preparing a significant alteration to its existing nomenclature.

Auto Guide has uncovered trademark applications made in Canada, and other markets, which suggest the German manufacturer could soon start referring to its non-AMG models with two-digit nameplates.

Traditionally, only the marque’s AMG models have had two-digit names (e.g 43, 53, and 63). However, the German automaker recently filed trademark applications for A 40, CLA 40, SLC 40, SLC 50, and GLE 50 in Canada. Furthermore, it filed to reserve CLA 50 in Germany and worldwide with the World Intellectual Property Organization.

While it would be easy to explain these names as being forthcoming AMG variants, they could very well be the first in a new naming scheme that ditches badges like CLA 250 and SLC 250.

The new trademark applications don’t stop here. Mercedes has also filed to protect CLA 53, G73, and S73, three names that seem very likely to adorn AMG models. It is reported that ‘73’ branded AMG models could come equipped with the brand’s hybrid performance powertrain, potentially delivering upwards of 800 hp.

One final trademark application is for the badge ‘Turbo 48’. It is speculated that this could refer to turbocharged Mercedes models equipped with 48V mild hybrid systems and may adorn all applicable models.

When quizzed about the patent applications, Mercedes North American spokesman Brian Cotter declined to comment.
