General Motors has followed up its announcement of a US$1bn investment at two of its Flint, Michigan, manufacturing sites to produce new ICE heavy duty trucks with a $500m spend at Arlington Assembly in Texas which builds the equivalent full size SUVs.

The latest spend is "subject to successful discussions with local government officials", the automaker said in a statement, adding: "This investment will enable the company to strengthen its industry leading, full size SUV business".

Product details and timings were not disclosed.

GM claimed the latest announcement took its US manufacturing and parts distribution facility investment commitments to $31bn since 2013.

GM noted Arlington Assembly had been "breaking production records this year".

Despite numerous factory closures over the last three decades or so, GM US manufacturing operations still encompass 50 assembly, stamping, propulsion and component plants and parts distribution centres US-wide.

"[This latest announcement] also highlights the company’s commitment to continue providing customers with a strong portfolio of ICE vehicles for years to come," GM said in a statement.

Arlington builds the automakers entire North American range of full-size SUVs: Chevrolet Tahoe and Suburban, GMC Yukon and Yukon XL, and Cadillac Escalade, Escalade ESV and Escalade-V. The company claimed it led the industry in this segment for the 48th consecutive year in 2022.

The spend will give Arlington new tooling and equipment in stamping, body shop and general assembly shops.

GM has previously announced $2bn in investments at Arlington Assembly since 2013.
