RG Prima Mercedes mode

It seems like you might be referring to "RG Prima" in the context of a specific model of Mercedes-Benz vehicles. However, I'm not familiar with a model called "RG Prima." Could it be a variation or a regional name for a specific Mercedes-Benz model? Alternatively, if "RG Prima" refers to a specific feature, mode, or performance setting in a Mercedes-Benz vehicle, please provide more context. Mercedes vehicles often have multiple driving modes (like Eco, Comfort, Sport, etc.) and advanced features that could fall under a specific branding or name. If you can provide more details, I'd be happy to help!
