It may start from $136,500 in the United States and €130,000 in Germany, but apparently the BMW i8 is in such high demand that the automaker has recently doubled production.

Currently, buyers of the plug-in hybrid sports car have to wait four and a half months for their vehicles to be delivered, BMW production boss Harald Krueger said at the company’s annual press conference. And that’s despite the fact that BMW has recently doubled i8 production at its plant in Leipzig, Germany, to 20 cars a day. Krueger explained the long waiting list with the fact that demand for the i8 continues to rise.

BMW sold 17,800 i3 and i8 models worldwide in 2014, 16,052 of which were i3s and 1,748 i8s. The United States accounted for more than a third of global 2014 sales, with 6,647 i vehicles sold: 6,092 i3s and 555 i8s.
