This is an old video, but I had fun re-watching it and see how GM did at delivering what was guided originally. A couple points as it seems GM hit all the performance targets. It seems GM is right on time as in this video recorded Oct 20 last year, TFL asks if the Hummer will be delivered by the end of 2021, and GM guides "it will be a year and a little bit from right now". Once again it looks like GM is right on target.
A couple interesting timestamps 28:40 delivery schedule
30:20 the top chassis engineer call it a "unibody" structure
