General Motors will add 263,000 sq ft to its newest plant in North America, the Lansing Delta Township facility in Michigan, which was opened in 2006.

The US$63m investment at Lansing is part of US$300m in Michigan investments announced by GM CEO, Mary Barra, at a speech to the Detroit Economic Club this week.

The investment is part of “ongoing efforts to strengthen key plant capabilities,” said GM North America Manufacturing vice president, Cathy Clegg.

“We’re committed to producing the highest quality and safest vehicles in the market, which will help us earn customers for life. This is why facility investment is so important.”

The expansion will add roughly 28,000 square feet to general assembly and more than 181,000 square feet to the body shop for the newest generation of robotics and lean flexible tooling.

A 54,000-square-feet addition to the paint shop will allow use of improved sealers and coatings to increase corrosion resistance.

Lansing Delta Township employs 3,300 staff and builds the Chevrolet Traverse, GMC Acadia and Buick Enclave large crossovers.
