I am figuring it to be 186” +\~ in length based upon a CAD overlay of the Lyriq with its known length and a spy shot of the side view of the Blazer. Obviously it’s not going to be exact that way, but the windshield slope and the roof look exactly the same. The front is just a lot stubbier for the Blazer and the rear doesn’t slope down as gradually as the Lyriq - it’s pretty vertical compared to the Caddy. The wheelbase looks identical. So I expect the SS version to have the full 100kwh battery and the cheaper ones to maybe have the 10 module pack with around 83kwh.
Possible, but I think better to wait for the specs from GM before jumping to conclusions. LYRIQ, has 5 link suspension front and back, and is designed as a RWD/AWD chassis, Blazer will have strut suspension and is designed as a FWD/AWD. Blazer, Equinox and Honda Prologue will share basic architecture, with mostly length differences. Track width will stay "close" to the same. I see no reason they could not build this RWD/AWD, but that was not the plan as I heard it. I am guessing Blazer has 10 module pack, and Equinox will have 8 module which works out to + or -88 kWh for Blazer and + or - 70 kWh for the Equinox I am quoting net usable kWh, not gross, I have no idea what the gross is. Lyriq has 105 kWh net. It's important to know Lyriq + upcoming Acura (Spring Hill built) does not share much with Blazer, Equinox, and Prologue (Ramos Azipe built). To be honest, I like the interior design for the upcoming Chevrolets, Equinox, Blazer, and SilveradoE, more than the LYRIQ interior layout. I think the Chev's look more clean and modern, and LYRIQ looks stuck between 2 generations.
