I see nothing special about that BMW, looks dare i say incredibly basic, its just blahh panemera is whatever 6:12 sums up the video
I don't speak Pig Latin so I could not understand him, but I would assume the fact that its a German reviewer might bias them, much like Top Gear is partial to British cars.
I thought so too, but it turns out that the he isn't biased. Hey says basically that Model S has more sportiness than Panamera. BMW 7 is the more comfortable and practical vehicle for long distance at the Moment, because supercharger network is not out yet in Germany. He also states that the BMW fells really from another older car-world, whereas Model S feels much like the future.
As stated by Matthias, your assumption is false. The review is fairly objective and positive for the model S. Speaking of superchargers, I wonder if Tesla fulfills its promises regarding the planning of the sc network in Europe. I hope so, it would be nice to be able to go to Spain in the Model S.
