Weather testing is a big part of vehicle development, and while automakers spend plenty of cash shipping cars all over the world for durability testing, there are some evaluations that are best done in a controlled environment. For that, companies turn to climate chambers. Ford's is particularly nasty, allowing engineers to subject new cars to temperatures ranging from -40 degrees Farenheit to 131 degrees, all the while varrying humidity,windspeed,road load, and altitude.
The chamber can even simulate snow, which how you wind up with a 2016 Ford Mustang Shelby GT350 engine bay looking like it spent too much time behind the chicken nuggets in your freezer.
