Huge thank you to Ontario Tech University !!! for the awesome invite to tour the ACE (Automotive Centre of Excellence) Wind Tunnel! 🌬️😎

We got a behind-the-scenes look at one of the most advanced climatic wind tunnels in North America and learned how they recreate wild weather—wind, rain, snow, and extreme temps ❄️🌧️🌪️—for real-world testing.

Such a cool experience and an incredible facility! 🙌🔥
