Same here, I like it way better then the Hummer, will be quiet and refined, my Hummer will be moving on soon.
I was wondering what you were going to do... You had said before that you really weren't a Hummer guy, and I was thinking that you wouldn't keep yours long, but then when you got it, and you kind of changed your mind.

The sierra is probably a better traditional pickup truck, and looks pretty much like a traditional dime a dozen pickup truck, and the Hummer, well….is far cooler! IMHO
I’m a Hummer guy and that’s how we think!
We don’t buy it for practicality we buy it because we want to stand out from the crowd!

5:47 talks about the infotainment and how it works.

GM's demonstration of infotainment and the actual operation in the real world is different. Hummer is literally the slowest I have ever seen in any modern vehicle, its embarassingly slow when demonstrating functions. Many times I think I missed a press and press again after a few seconds, sending me into a frustrating loop of presses. It's aggravating, and really awful for a new platform in 2022. One thing though I give GM credit for, the truck starts quicker then a Tesla, many times I hop in my Tesla and shift before it is ready, and I have to shift again and again before I can get going.

The advantage with Tesla is the use of more up to date CPU power, traditional OEMS still used older known robust silicon for their computing elements. I know GM has been pushing hard to try and update that. Future vehicles will be using their own in-house developed silicon.

The Lyriq is also using/introduced a new snap dragon processor for its infotainment.

Yes, GM still uses a multitude of supplier systems in the infotainment that piggy back off their main system. Tesla writes all the infotainment code in house, and has control over all of it. This goes back to GM's old supplier thinking, GM keeps putting band aids on a hemorrhage. Decades of MBA's running GM have killed internal innovation, and everything is sent out to the cheapest supplier. GM judges these things on a spreadsheet, but the spreadsheet only tells part of the story, one example is the camera system, GM has more cameras and views than Tesla, so they win on the spreadsheet, but Tesla software control is so much better and feature filled, GM's camera app in the Hummer is such a crap interface and really drags down the whole user experience, looks like it was designed in the 1990's (likely was)

Sierra-Silverado differences are only skin-deep.

Below are structural profile images of both the Silverado and Sierra Denali. Other than the different structural/aero gusset-sails between the cab and bed, they are almost identical.

I see a few differences here and there... also looks like they found places to reduce weight on the Sierra.

Yeah, a few differences, mostly cosmetic, plus the added holes in the hood tusks and the C-pillar gusset re-shaping. The A and B pillars, roof and bed profile lines, front structural bumper and drive unit tusks, door opening shapes and hinge mounts, charge port, and seat mounts are all very-close matches. The truck-equivalent to 23andme would probably find about a 90% DNA match:) The Silverado engineering team probably pioneered a lot of the basic structural-bone details, saving the Sierra team a bunch of time that could then be used to optimize the design.

It also helps that Nicole Kraatz, the Silverado EV Chief Engineer, has a new title: "Chief Engineer, Battery Electric Trucks", overseeing all Chevy/GMC BEV truck engineering going forward.

A well-earned upgrade, IMHO:)

Hummer version 1.0 of the BT1, Silverado And Sierra production models are 2.0, the SilveradoE concept was a soft tooled prototype, the production models of the Sierra, and Silverado will have the same structure and systems under the skin

I was just punching out the new total HP ratings for the Denali and Silverado top trims and working out what the new kW per-motor-rating would be. They were originally rated as 250 kW drive units front and rear. The new kW is 280 kW each, significantly higher than the Hummer's individual motor ratings. And there is no "WTF" pre-prep required to tap that full power, which included pre-ramping up the drive unit cooling loop. That is a major uprating. I'm wondering if the up-rate is just re-rating thanks to additional re-world validating or if they also changed something fundamental...perhaps GM will be slipping Wolfspeed SiC MOSFETs into the ED1 inverters?? Those MOSFETS require about 30% less cooling and improve drive unit efficiency about 1%.

HummerEV is pulling more then 280 kW on the rear motors in WTF.... Using my drag calculator, it has to be making over 1200 HP to run its best times, and the front axle hooks up very little power, its mostly coming from the back
