Mercedes-Benz’s parent company Daimler recently filed an application with the World Intellectual Property Organisation to trademark the "C53" badge. And now another application has popped up, this time for the Mercedes-AMG G53 nameplate.

Yes, the studious folks over at AutoGuide uncovered the latest filing, which suggests that a new AMG-badged version of the second-generation G-Class could be in the offing (to slot in below the existing 430 kW/850 N.m G63). Whether this proposed model will employ the electrified 3,0-litre inline-six petrol engine used in the E53 and CLS53 remains to be seen.

We'd speculate that the six-cylinder inline petrol unit, which generates 320 kW and 520 N.m before its “EQ Boost” starter-alternator momentarily adds 16 kW and 250 N.m in the E53 and CLS53, would need to possess a bit more grunt to do duty in a G-Class, seeing as the G500 already makes 310 kW and 610 N.m.

Interestingly, however, the US publication added that it had also found a filing for the "G43" moniker, despite the fact that the product chief for the G-Class earlier in 2018 effectively ruled out a V6-powered, G43-badged derivative, explaining that Geländewagen buyers “love the V8”.

In addition, earlier reports suggested that the Stuttgart-based brand had applied to trademark the G73 badge (as well as “S73” and “GLS73”), which rumours suggest will eventually be worn by a flagship powered by a twin-turbo 4,0-litre V8 complete incorporating a plug-in hybrid arrangement.

Confused? We don't blame you. But, as AutoGuide points out, regardless of which of these badges actually eventually make it onto production vehicles, Affalterbach has a busy few years ahead...
