(Tesla's) "Model S was the only vehicle in its class with growing sales last year. Even on our competitors’ home turf and in countries without government incentives to purchase electric vehicles, Model S is winning.

For example, in Switzerland, Model S outsold the Mercedes Benz S-Class, the BMW 7-Series, the Porsche Panamera and the Audi A-8 combined for the full
year, and also outsold the Mercedes Benz E-Class.

In Germany in Q4, Model S outsold the Porsche Panamera. Finally, across all of Europe last year Model S outsold the Audi A8 and A7 combined and the BMW
7-Series and 6-Series combined"

In fact the only car of the "traditional" big 3 that seems to have (relatively) stable comparable sales volumes is the Mercedes S-class with 21,934 units sold in 2015 (Model S units sold 25,202) compared to 25,276 units in 2014 (Model S units sold 16,689).
