Interesting to read a bit about it. I have some friends working on this program, and I've worked with Brent Deep in my former life, working on the 2009 and 2011 HD truck platform. Seems like he was messing with "aero points" most of the time I knew him. Nice enough fella, but at the time, wasn't fighting for "all things truck". (The eurea tank is a GREAT example...) Hopefully he's on board with the ZR2 Colorado.
Bold contrast to the "offroad" trip we took with the HD's to Colorado. I was heading up a mild trail to work on brake traction control and the "truck guy" from GM had a complete and total fit when I dragged the tailpipe of the truck on a rock trying to get it a bit more crossed up. He was genuinely sure that I was breaking the truck in half... That guy and I never did get along. I had too hard a time explaining physics to him. I didn't do much off road development with him around after that...
For the ZR2, I know that they're getting direction from some pretty qualified people outside GM, and I consider that a
really good thing!!
If only I had $50k to blow on a truck... Ah, I still probably wouldn't. I like my full size Duramax too much.
