BMW auto transport has an Environment Test Center (ETC) that can test a car in a variety of environments – sun, ice, snow, rain – all of them indoors. As great as that would be for parties, they appear to put it to actual work, testing the engine and cooling systems in roadsters like the Z4 in 113 degrees Fahrenheit. The facility can also get down to 14 degrees, conjure wind up to 150 miles per hour, and even mix it up with snow and wind and rain.

Icemistress Katarina Witt dropped by to take a tour, and while they did make a bit of ice and snow for her, they also took a lot of simulated sunny day pics and made a little movie. Follow the jump to watch the video (auf Deutsch), and have a look at the photos in our high-res gallery below.
