Toyota Motor Corp. has raised its group-wide global production and sales projections for 2018 to record levels, driven by stronger-than-expected sales in China and benefits from lower auto tariffs there, a source close to the matter said Thursday.

Japan's biggest automaker by volume lifted the group output target for this year to a record 10.59 million vehicles from the previous projection of 10.40 million, the source said. The new projection represents a 1.2 percent increase from 2017.

Group sales are now forecast at 10.52 million vehicles, up from the 10.50 million projected previously, according to the source.
