AT4X Bolster Off-Road Performance in Two GMC Models, Canyon and Sierra

3 mechanical locking diffs would be better, but for what these will probably be used for the off road stuff they put in them will probably suffice. 
 

These engines are getting dated, the Jeep inline six is 420 or 510 hp, I have to imagine that ends up in the Ram next year as the Hemi’s days are numbered.  The Tundra hybrid has a big power advantage over the GM 6.2 liter as well.  I don’t know if GM plans to do anything with these powertrains or just let them die on the vine and put 100% of what they have into EV’s.

My gut is we will see programming upgrades only to these ICE engines, the days are heavily numbered on ICE and I expect far superior EV powertrains for the trucks to be coming in the next few years.

I watched Mark Ruess on Outline the other day, he said if he got $1 for R&D, he is going to spend the whole dollar on EV's.  So the ICE powertrains they have now are it until they are gone.  Which is a good move if people adopt EV's quickly, bad move if people don't buy EV's and keep buying ICE cars.

Tundra: 389hp/479tq

GM 6.2: 420hp/460tq

What "big power advantage" do you speak of?

Sorry, you mentioned Hybrid which is significantly more powerful at 438hp/583tq. 

I am a little surprised GM hasn't hybridized their truck engines at all yet.

Yes, the Hybrid Tundra has a big power advantage.  But even the SR5 Tundra at $43k is 389 hp/479 lb-ft, you are mostly looking at Turbo 4 at GM,  maybe the 5.3 V8 or Pentastar V6 at Ram or 2.7 Ecoboost at Ford at that price.  Toyota kind of beats them all on powertrain now, plus it is based on the Lexus LS500 powertrain, so we know that engine/transmission has to be smoother and more refined than any other truck.

GM sees spending money on hybrids as a waste of R&D, Mark Ruess said they want to put everything into EV.  So I would imagine if you can still buy a gasoline Silverado in 2032, the 2.7 turbo 4 and 6.2 V8 will still be there.

Even if it isn't the turbo-4 and it's the 5.3, that's still only 355hp/383tq. 

I guess I never really realized until now that they are all down a little on power/torque. 

I still think the plug-in hybrid would be a great way to get people into electric vehicles, but I'm not the one in charge of these decisions hahaha.

The turbo 4 has more torque than the 5.3 V8 so my guess is that V8 isn’t around much longer.  Much like that Wagoneer V8 I think will be gone soon because the in-line 6 makes more power.  All these V8s are probably dead by 2025.

I remember that Mercedes canceled all of their V8 offerings not too long ago.   OK...so I read that Mercedes will bring back some of their V8s in some of their SUVs.  But Mercedes canceled their V8s.  GM hasnt canceled theirs, havent made ANY announcements of ANY cancelations OF their V8s.  (other than the fact that   will be a battery electric car company in the very near future as announced by their governing CEOs)  

So...hybrids are a brand new rage for full sized trucks in 2022?

Its as if GM never offered hybrid tech in their full sized trucks before.  

Like a decade ago (or even less) or anything...

Its not as if GM aint working on a full-on, 100% battery electric truck or anything...for the future as how they explained that eventually ALL their offerings will BE battery electric meaning eventually all of their internal combustion engines will be gone, not JUST their V8s. 

Yet somehow, surprisingly,  its not as if they are hard at it in keeping hard core V8 performance around in their trucks....

Yeah...that is all gone...

When Ford, GM's main competitor in this market,  decided to go all  turbo ecoboost V6 in this arena and provide a base engine with a helluva lot more power and torque than GM's base V8 5.3 liter.

Yeah...doom and gloom for that base 5.3 liter also happened... 

So...it seems that Toyoter, came up with a BRILLIANT idea to  hybrid-ize their Tundra in 2022 wheen they had Hybrid tech a decade ago

and THIS will spell doom and gloom for  .  Its actually this  now...
