Because the wait list is already up to 18 months.
Although it hasn’t been signed off on just yet, it’s nearly all but certain that BMW will decide to increase production of its i8 plug-in hybrid sports car. The reason is demand and lots of it. At the moment, there’s an 18 month wait list for anxious customers, according to BMW’s sales and marketing chief, Ian Robertson. Speaking with Automotive News Europe, Robertson said that his company needs "to find ways to increase i8 production because the waiting lists in some markets are getting too long."
According to him, six months is the maximum time people should wait for their order. Built in Leipzig, Germany, the i8 only went on sale in Europe last June and August in the US. BMW won’t state current production numbers or any potential increase figure. But for something that was intended to be a low-volume model with annual sales "in the low single digit thousands," the i8 is proving to be a hit. So now BMW has to figure how to satisfy those buyers as well as maintain the i8’s exclusivity and future collectability.
