We had our first snowfall and it was significant event. Lot of snow, slushy ice. A lot of accidents and spin outs. Made for a slow commute home. Put the TB in AWD and it made the drive much less tense. Handled well in the bad weather.
I consider it a sad day in the vehicles history, as it now will be subjected to all the contaminants of salt, sand, beet juice solution they spray on the road surfaces prior to winter weather events. It will now be harder to keep it clean.

Rinse and wash as often as possible. The salt is probably the worst enemy.

AWD is really only 2WD (1 front wheel & 1 rear wheel). I wish we had some sort of limited slip in our differentials to increase traction even more, but at least power is going to the front and rear which increases stability.

WHAT? This AWD is just one wheel up front and one out back moving the TB?

Yep. It's because we have "open" differentials. Under certain conditions where 1 front wheel and 1 rear wheel are losing traction you won't move at all because power always goes to the wheel with the least traction. In some vehicles traction control can help by applying the brakes to the wheels spinning which gives the other wheels traction again, but I don't thing our Trailblazers work that way. Usually that feature is on higher end models with AWD. 1 front and 1 rear wheel with traction in AWD is still better than just 1 front wheel with traction in 2WD.

My 2018 ZR2 is one of the only true 4WD vehicles on the market. Under normal driving in 2WD I'm really only in 1WD, but I have the option to engage lockers on the front and rear axles to have real 4WD. If I'm just in 4WD without the lockers engaged I'm really only in 2WD just like the Trailblazer in AWD.

Kinda not understanding how they can say AWD when it is not.

Well, when you're in AWD, all of the wheels share the power, but only 2 can have full power. If you were to raise 1 front and 1 rear wheel off the ground while in AWD you would notice that the 2 wheels off the ground would spin while the other 2 still on the ground would do nothing. If you somehow did this under normal driving on road or off road you'd basically be stuck and unable to move. I'd really like to see some pics of the inside of each differential to see if it's possible to design some sort of limited slip, whether it's a spring loaded clutch pack, a spring loaded cone with seat, a helical gear posi or electrically actuated locker. Any of those could transform our (2WD AWD) into a true 3WD or 4WD. I agree it's misleading to call something AWD when it really isn't, but we also have trucks advertised as being 4x4 when they're really only 2WD or 3WD when in 4WD.

Lessoned learned for me. Sooooo my 2001 Z71 when in 4x4 is not true 4x4?

Yes that's correct. It probably has GM's auto locker rear end (Gov Loc), but no front limited slip or locker so you have a true 4x3 or 3WD. My 05 ZR2 Blazer is the same as your 01 Z71, 3WD. You can add a locker to your 01's front axle, but I hear they like to break things so I've avoided doing it to my 05.

I would like to know how the Trailblazer's torque is split between the front and rear axles? GM hasn't released this information yet, but most people suspect it's close to 50/50 front/rear which should perform well in snow and other slippery conditions.

Winter tires is your best friend regardless of 2WD, AWD or 4x4 I've driven RWD Camaros for over 8 yrs in new england winters and only the first on the stock all seasons was it shittyish as they were new but lacked that extra traction and compound a true winter tire has.

What winter tires do you recommend based on your experience with New England winters which can be brutal? I've heard good things about Bridgestone Blizzaks, but have never tried them, so I can't say how well they really peform.

I've had blizzaks they are good but overpriced I still maintain the Firestone winterforce are criminally overlooked. I've had winterforce and blizzaks on my 2017 the winterforce are marginally better plus the ability to stud them and alot cheaper. I had the winterforce studded on my 2011 V6 Camaro thing could go from a dead stop on a steep hill no issues.

As far as new england winters they can be brutal the issue is most municipalities don't plow anything under 4 inches until the cleanup so you get the ice pack...

I wouldn't get too concerned about what wheels are really driven. Normally, with equal traction, it is all wheels. It's under uneven ground that things get dicy, but for road/snow use it will be better than FWD. As for tires, the "Active" package already comes with an "All Terrain" tire that has a fairly high amount of Silica which will enhance traction in low temperatures and snow. Good tires will be the single most important factor in those conditions. Also, there is a rudimentary "traction control" system on the vehicle I believe which will apply brakes to a spinning wheel to force the torque to go to the other wheel on the axle what has better grip. It may not be really quick acting, but it will get one out of most situations (again - not hard core off-roading). If you don't have the Active package with the All Terrains, there are so many on the market, take a look at your tires and you can either put on dedicated snow tires for winter or a more general All terrain. There is also a new emerging type of "all weather" tire which might be the ticket for some folks. (sample all weather).

I did get it in a parking lot today that was covered and it seemed that the TB did better in not getting squirrely and losing control as the AWD was on and the TC was turned OFF. Seemed the AWD worked better, was not breaking loose since the TC was not trying to do what it does.

I Just wanted to chime in that the All Wheel Drive system on these vehicles will get the job done in a fair amount of situations. When activated it can push power 50-50 front and rear through the power transfer unit and the system is capable of vectoring power to the left and right tires using brake force distribution. Using the wheel speed sensors when the car senses a wheel rotating faster than the others it will brake that individual wheel distributing that power back to the other wheels. Sure it would be nice to get the twin clutch awd system but that adds a cost. Not a lot of buyers are willing to pay the additional costs for a system like that especially when this system is capable.

I mean I could drive through an icey snow packed field at an incline without issue in mine even with the shit OEM all season tires. The AWD does work but people are right about the TC causing normal driving issues, one of which you alluded to in your explanation Trunks817. It can and has in my experience triggered ABS more often then with it off and if you've ever been we'll call it assisted into a busy intersection by force then you know what I'm talking about.
