The company reportedly already has 2,000 orders for the Mirai just in Japan, and an anonymous Toyota executive tells Automotive News that the waiting list is now "two years or something" to receive one. Keep in mind, this figure is before customers elsewhere in the world have any requests in, and the US launch is planned for California this fall with sales in Europe starting this summer. The automaker is keeping North American demand somewhat in check by only planning to move 200 vehicles or fewer on the West Coast in 2015.
So, unless Toyota can pick up the production pace, the waiting list seems likely only to grow longer. Automotive News speculates that the company might be in danger of Mirai customers losing interest if they are forced to build anticipation for too long. That especially could be the case with a new Prius likely to be unveiled by the end of the year that could lure folks away
It seems that Toyota is trying to react to the higher-than-expected demand for its hydrogen-powered model, though. In December, the automaker invested $168 million to add two more assembly lines for the Mirai's fuel cell stack and hydrogen tank.
