I think it was meant as:

Production models including B-class[segment], C-class[segment], compact SUV or;

Concept Car

Parts of this are poorly written, like it was given to the work experience lackey to type up. Some parts are written as if from 2026 the cars will be breaking new ground (‘common safety cell’, possibility to be based on B- or C-segment models, SUVs), but isn’t that just what has been the case since 2022?
