The leadership team at Stellantis has faced an onslaught of scrutiny after the automaker’s lackluster performance so far this year – underscored most recently by a 20% Q3 drop in U.S. sales.

And as one part of its strategy to cut costs and improve margins, Stellantis will reportedly sell off a facility in Yucca, Arizona.

Getting the ax is the company’s Arizona Proving Grounds, a 4,000-acre site Stellantis uses for testing. Purchased in 2007 from Ford Motor Company, the grounds include areas to review and assess vehicle dynamics, durability, noise, vibration and thermal limits, and includes 100 lane miles of road surface.
