This is largely a function of their brand positioning. There are about 20 models of car under about 6 brands on the VW MEB platform, all, well, very similar (except the weird microbus thing). Tesla has instead chosen to go for two models under one brand.

Both are _valid_ approaches, and you see both from other companies (eg GM leans into the many brands thing fairly heavily, BMW is single brand few models), but it does make claims of "this is the best selling vehicle" rather uninteresting.
