If you have been in the auto business long enough you hopefully remember from a few decades ago the movement to rationalise the number of models that were offered by a make. At the time the rationale was the Europeans and Japanese have less models.
Back in the day, Chevrolet as an example had a myriad of models and body styles, the same for Ford, and Chrysler. The thinking was to cut back on the number of models, to stop trying to fill every minute segment of the market, while selling more vehicles, and improving profitability.
The Japanese had dramatically less models, and were inexorably gaining ground.
Once the models were rationalised, the focus shifted to decreasing the number of platforms. When you hear that a manufacturer has gone from 15 to 5 platforms. You can conclude that they are saving money while increasing profitability.
You also remember when models had an actual name, and not an alpha numeric (alphabet soup) nomenclature. Today the names are still around, Impala, Taurus, Camry, Accord, Elantra, to name a few. While the alphanumeric also thrives and seems to gain in disciples. A few examples, 3 Series, X5, CLA250, RX300, CTS, A3 to name a few.
From a manufacturer identification most vehicles have a body/platform identification; its a B Body, a W222, and a model designator its a 7BL57, 1BP67.
If you get the feeling that the model designators are creeping as "marketing" model names that are used to identify the vehicles in the market, we agree with you.
If you get the feeling that some manufacturers are establishing a parallel model line up with even more alpha numeric identifiers, we again agree with you.
Not only do the additional alpha numeric names confuse, you have to ask if they do not also dilute.
This business that constantly pushes the envelope, 1 is good, 2 is better, and 3 might be too much; with a fine line between 2 and 3.
If you think that some manufacturers are close to, or even past the 3, be patient it will be clearer in the following months. Its the classic case of sell 10 with 3 models, sell 12 with 6 models, sell 13.5 with 8 models. The sales are increasing along the the complexity, confusion, dilution, and perhaps even values.
