Marques Brownlee is one of the top tech YouTubers out there and he's stretched out to the automotive world, since that is becoming very techy with the advent of electric vehicles. The folks at GMC brought by both the Hummer SUT (pickup) and the SUV to his studio and let him crawl all over them and film them for us. Interestingly, he found some cool things that I'd totally forgotten about as well as things I hadn't seen. So, if you have any interest in these vehicles, you're definitely going to want to watch this video. Enjoy, and tell us what's you favorite feature. Marques admits he really like the headlights, with their party tricks. Myself, I'm leaning removable roof.
