The eyes of the auto world were on Arlington Tuesday night as General Motors unveiled the all-new 2021 Chevrolet Tahoe and Suburban.

The full-size SUVs are made exclusively at the Arlington Assembly plant, which employs about 4,800 workers. The plant, which opened in 1954, runs six days a week and will occasionally add a seventh day, based on demand. 

GM has invested more than $1.4 billion dollars in the plant since 2015 to expand the paint and body shops and add high-tech inspection systems. The company says those upgrades helped improve production-efficiency and build-quality of the new 2021 models.

“More than the physical changes, the Arlington upgrades increase assembly flexibility in the plant, allowing for more model and trim variations,” said Arlington Plant Executive Director Bill Kulhanek.

The City of Arlington worked with GM in 2015 to make the investment possible, creating a reinvestment zone and tax abatement plan. 

With the expansion, the Arlington Assembly now covers more than 5.75 million square feet. 

The 2021 Tahoe and Suburban will be on sale in mid-2020.
