It's for cars produced in Germany produced by Volkswagen, Daimler or BMW, so the car selection is very limited (several of the cars in the photo aren't subsidized because they cost more than €60k). Germany will subsidies €2000, the remaining rest (up to €2000) come from one of the three companies - basically a price discount.

Isn't there a similar subsidies/discount in California(?) where you get $5000 if you buy an electric car (manufacturer doesn't matter afaik)?
