If you’ve never gotten to see future model year vehicles out high altitude testing, you’re missing out. Engineers take new models, usually adorned in complex camouflage and added body accessories so as to not let out all the secrets of the future designs, to mountain ranges across the country to test out the capabilities of vehicles to handle soaring elevations. But in a recent high-altitude test trip conducted by The Block, the models weren’t new. In fact, they ranged from newer all the way back to the latest Pontiac GTO and the 3rd Gen Camaro. Check out the symphony of engine and exhaust sounds The Block captured on their test trip in the video above.

For The Block’s high-altitude test, a group of engineers with a smattering of GM models consisting of a third and fourth-generation Camaro, GMC Sierra, Pontiac GTO and Cadillac CTS-V, took to the Western United States. On this side of the country, you can go from below sea level to over 14,000 feet in elevation within just a short distance, making for a perfect place to test altitude tolerances of vehicles.

Along the way, the GM engineers hit Virginia City, Utah and the Bonneville Salt Flats, which sits at 4,219 feet above sea level. While we don’t see any major pushing of engine demands at these locations in the video, the chorus of GMs sure make some amazing sounds, even at higher elevations.

While we’re pretty sure each one of these vehicles went through high-altitude testing before they were available to the public, it sure makes for a good excuse for another high-altitude trip in some great GM models. Now all we can hope for is some high-altitude testing footage of future Chevy models!
