The Arlington, Texas plant that builds full size SUVs like the Chevrolet Tahoe and Cadillac Escalade will get a third shift, adding 800 jobs.

The shift is expected to start in Q1 2013. Sales of the full-size SUVs have been steadily climbing in the post-Recession years, though volatile gas prices and the consumer shift towards more fuel efficient vehicles makes this move slightly puzzling – or not, in light of Bertel’s article on just how important full-size trucks and SUVs are to the general. The Tahoe, Suburban, Yukon and Yukon XL command a significant share of the large SUV market, with both the Tahoe and Suburban handily beating the third place Ford Expedition in the sales race.
