I'd also read sometime ago, that post "chipgate" the general consensus is that the manufactures won't go back to the same business model they had before. They are already prioritizing models that net them the most margin, and apparently (if you believe what you read on line), that will continue, and by "artificially" limiting supply they can keep the prices inflated.
Not sure how this will work personally, because for every person that can afford a €40-50,000 plus car, there's probably 10 or more that can't or won't spend that amount of money on a new car. So if (for instance), VW make 100,000 cars a month, and they decide to produce only the expensive or high margin ones, then how many will they sell a month, 20,000-30,000 ?? Even with increased pricing and margins, can that make up the shortfall of 70,000 lower priced and margin cars a month that they won't be producing ?
Personally I think think it will still be about volume and an even spread of upper tier though middle to lower tier models, but all with increased delivery times to make the market aggressive to keep discount levels offered to an absolute minimum. That's provided all manufactures do the same though. If one or more rivals think they can steal market share by under cutting the big German Marques though aggressive pricing strategies, then BMW, VAG, Mercedes etc. would surely have to follow suit ?
