How do you mean up 22%? Remember 2013 was only 6 months for Tesla delivery in Europe, so it's actually a decrease, entirely the result of regulatory changes that reduced tax benefits for owning full electric cars. A more stable picture includes the whole of Europe. It is reasonable to project 8500+-250 cars for 2014. This compares to 3893 cars in 6 months in 2013 or up roughly 10% on a full y-on-y basis.
As to the feel of a delivery push : yes, this can easily be seen by anyone passing Tilburg. There were way more cars there in December than usual, although things aren't as hectic as in the states I assume. Another 'feel' is that there won't be (comparatively) as many original enthousiasts who will switch to a D model as there were in the US. Interest on the Dutch board is certainly lower. Again, going by feel, I think Europeans are more wowed by top speeds rather than incredible acceleration in performance cars. In personal conversation, when someone is talking about a 'fast car' it's always about how fast you've driven it on the autobahn, not how fast you peeled it at the red lights. Also, the slightly larger range from the dual motors isn't a big bonus here since distances are way shorter and supercharger density higher. However, this may not be true for Norway where AWD may make more of an impact.
With a rising dollar, comparatively little interest in the D model and certainly no model X deliveries, I expect sales in Europe for 2016 to be down in the countries where Tesla has reasonable (sales supporting) infrastructure build out already (mainly Benelux, Germany, Switzerland and Norway) and up in countries where it is still setting up the infrastructure (mainly France, UK and central-east Europe) All in all, it is going to be a wash with 8500 new Tesla model S (all varieties) hitting the road during 2016.
