Toyota has announced that demand for the Mirai has exceeded production allocations for the 2016 model year on the US market.

The company has received 1,900 order requests since the online portal went live two months ago. The number represents nearly double the 1,000 units that will be headed to US showrooms for the year.

The existing order requests are being reviewed, and Toyota will begin placing the first trailblazing customers in the Mirai driver’s seat this month,” the company said in a statement.

The ramp up is slow. But, according to the DOE (Department of Energy), there are only 12 filling stations in the United States. Of the dozen locations available, owners claim some are regularly offline or only filling tanks to half capacity.
