According to Auto Motor und Sport, the facelifted M-Class will be renamed the GLE-Class, helping to align it with the E-Class in Mercedes’ hierarchy of models. Then, for the 2016 model year, Mercedes will launch its BMW X6 rival, which instead of being an M-Class Coupe, as currently thought, will be labeled the GLE-Class Coupe.
The next-generation GLK-Class will also be affected, with its name said to be changed to GLC-Class to align it with the C-Class. It's expected to be launched late next year, as a 2016 model. If a version with coupe-like styling is launched, expect this model to be called the GLC-Class Coupe.
There’s been no mention if the G-Class and GL-Class models will also be affected. While it’s likely the G-Class will keep its name due to its iconic status, it’s possible the GL-Class gets rebranded a GLS-Class to align it with the S-Class family. At the other end of the spectrum sits the GLA, aligned with Mercedes' A-Class.
Stay tuned for an update.
