2020 GM/Chevy gas 6.6L max towing test

For the weight they were towing and at that altitude, I think it did ok for a small block non turbo gas engine. That thing was probably gasping for air. Part of finding the true towing potential would be shifting gears manually if needed. I couldn't watch the whole thing since that one guy sort of gives me the creaps. It will be interesting to see a comparison with the Ford and Dodge gas engines. I very much doubt they'll do that much better. Gas,extreme weight and altitude are not the gas engines best friend.
