The BMW i8 is selling like hotcakes, and has been since the German manufacturer opened the order books for the hybrid sports car. It took only a couple of months for the i8 to sell out in the UK, and three more for the Euro-spec model’s waiting list to grow to a whopping 18 months. That period has decreased to around four months in 2015, but it’s quite obvious that the Germans are still struggling to keep up with demand. As a result, BMW decided to double i8 production at its plant in Leipzig, according to company production boss Harald Krueger. The facility now builds 20 cars a day, which should help shorten the waiting period to a more reasonable two months.
