Toyota will now spend almost US$13bn by 2021 at its US operations and will add about 600 new jobs.

It will also build hybrid versions of the popular RAV4 and Lexus ES in Kentucky for the first time.

Production capacity will be increased and buildings expanded at plants in Huntsville, Alabama, Buffalo, West Virginia, Troy, Missouri, and Jackson, Tennessee.

The company had in 2017 pledged to invest $10bn over five years.

As well as adding the hybrid output at Kentucky, Toyota will expand engine capacity at Huntsville, Alabama; double hybrid transaxle capacity in Buffalo, West Virginia; and expand a building for additional castings at Bodine Aluminum's Jackson, Tennessee, facility as well as additional castings at its Troy, Missouri, facility.

"These latest investments represent even more examples of our long-term commitment to build where we sell," said Jim Lentz, chief executive officer for Toyota Motor North America.

"By boosting our US manufacturing footprint, we can better serve our customers and dealers and position our manufacturing plants for future success with more domestic capacity."
