Oh common, didn't you notice that there was a huge drop of gas price last year? And the numbers shown for the German Big 3 is specifically the change of sales between 2014 and 2015. Yes, SUV and CUV have been in the market for decades, but the numbers that you are looking at are specifically the rate of change in one year time span, not decades.Except SUVS and CUVs have been around for decades and those who want one have always been able to buy them. And wouldn't Tesla be affected by the situation as well?
There's no way to spin this and I'm sure the Germans are still somewhat in denial but Tesla managed to decimate the upper end of the premium/luxury car market.
And they are just getting started.
There are multiple reasons that causes drop of German sedans. Model S is only part of that reason, majority of the reason is because people are accelerating their pace of transitioning to SUV, in which that sudden acceleration is caused by sudden drop of oil price.
We could argue about this all day long, but saying German sedan sales drop last year is 100 percent because of Model S is just lack of understanding of statistics and market dynamics. Let's just wait until next year and see what the numbers will be like for 2016 full year, then we will know for sure. The change of oil price will be less of a factor that affect the market dynamics between year 2015 and 2016.
