Toyota has insisted it still plans to open its latest US plant in Mississippi in 2010 despite Japanese media reports that it is considering a delay of  a year or more.

The company said in its fiscal Q2 results announcement it was reviewing all future production projects but a spokesman told Japanese media no decisions had been made.

The Nikkei business daily had reported earlier that falling North American sales had forced Toyota to consider postponing the start of production to 2011 or later.

The Mississippi facility was originally planned to build the Highlander but Toyota decided in a production reshuffle earlier this year to build that SUV in another US plant and make the next generation Prius hybrid in Mississippi instead. The current Prius is built only in Japan and China.
