Toyota City, Japan – Toyota will increase monthly output of the all-new 2010 Prius by at least 25 per cent, according to a report by the Green Car Congress.

The increase will begin in June and will bring monthly production to 50,000, up from the 40,000 originally planned, based on more advance orders than expected.

The report said that production in fiscal-year 2009 is now expected to total about 500,000 units, including April and May, substantially up from the 300,000 units initially forecast.

Pre-orders began in April and exceeded 40,000 last week. They are expected to keep climbing to anywhere from 60,000 to 70,000 before the launch date. The report said that advance orders alone may come close to the total fiscal 2008 sales of the second-generation Prius in Japan, which came to 70,618 units.
