One of the main reasons is that ordinary cars are heavily taxed, while electric cars are not taxed at all. This makes a Model S cheaper than most BMW or Mercedeses for example.
Add to this that electricity is cheap, while fuel is expensive. Also, Norway's wealth is relatively evenly distributed while at the same time the GDP is high. All these reasons makes it affordable for a lot of people to Buy a Tesla Model S.
While I have seen a few Model S on the road, I can't commute to job without passing a quite a few Nissan Leaf. Those have been sold in large numbers here (3% of all cars sold first half of 2013).
