Type designation CL instead of S-Class Coupé

Soon a new C-Class coupé will come, which is also based on the C-Class. It will be called C-Class coupé. The current E-Class coupé is also based on the C-Class, but it is more expensive and looks like an E-Class and is called E-Class coupé, although it is actually a C-Class. The CL, which is not to be renamed S-Class coupé after its facelifting, although it is technically and visually an S-Class, will continue to be called CL. However, the name CL is very bad, since it is also based on the C-Class coupé. still too much reminiscent of the simplest equipment variants of old Golfs I-III.
