So you're basing your conclusion on a graph that's mixing EV and PHEV? And only for the month of August? BTW due to its seasonality you cannot make any assumptions about the car market by looking at only 1 month.

Even if that chart is only for one month, the website does include sales data for longer periods. Back in August 2016, they published an article claiming there are now 500,000 EVs on European roads.[1]

I think one interesting point to keep in mind is that German manufacturers aren't the only European game in town. The Renault Zoe is the overall best selling European EV. Also, addressing an earlier comment, the Zoe EV doesn't look exceptionally futuristic. It really is an almost exact copy of the petrol Zoe. I find myself just looking for the exhaust in order to distinguish the two from a moderate distance.

Smaller, city going vehicles have a history of being more popular in Europe (Fiat 500, Mini, Polo, Smart etc), where roads don't tend to be as wide. I see quite a few Zoes and i3s in my moderate sized European city. They feel like the perfect commuting vehicle and second car, even if not particularly suited to long motorway miles.

Mixing in PHEVs doesn't hurt anything. Just ignore those. The conclusion remains.

Mainly because of price. When Model 3 arrives it will probably sell 4x as many in Europe, both because it will be a bit cheaper, but also because it will be a much better car.

You are misinformed. They are priced pretty much identically. I can get a new BMW i3 for 36.500€ here in Germany. I bet the Model 3 will be just as expensive.
