I forgot the Cybertruck, I guess I'd put that at an 8 if it ever comes out.
Correct. In fact, once all the numbers are in, I'll bet the lightning and the Silverado are a lot closer than you think. 😎The way something looks doesn't necessarily translate into a good drag coefficient. I don't think GM has published it for either the Hummer or the Silverado.
While I agree that ''looking aero'' doesn't necessarily translate to good aero numbers, I have to disagree about the Silverado compared to the Lightning. If you look a pics of both in profile, you see that the Ford has much more of traditional pickup shape, while the Chevy is getting into a more teardrop shape. Ford was smart to keep the shape of the best selling truck in the US and they are selling a lot of trucks. Chevy, with a completely new design has moved the pickup shape forward and I think it will pay off at highway speeds.
At highway speeds, unless you are going uphill all the way, aero becomes much more important than weight. I'm mostly concerned with highway driving. We will have to wait and get reports from actual truck owners, but I think the Silverado is going to be stellar on the highway!
Only 2 inches of adjustment, so I would assume 1 up and 1 down, but maybe it is just 2 down. My R1T has almost 6 inches, which is spread across 5 preset height, and at it's lowest the ride is terrible. I sometimes let it go down one level at highway speeds, but usually keep it at standard height. It really doesn't make that big of a difference.I'm pretty sure that they have air suspension, except for the WT. I don't know how low thy will let you go though.
As a professional pilot, I know a few things about aerodynamics, maybe not as much as a wind tunnel engineer but more than most.while the Chevy is getting into a more teardrop shape
