Considering the wide, fat, half bald street tires in very loose dirt/sand the AWD system worked well. I was curious and wanted to see how well the AWD would handle a low traction situation. It was fun to experience the system work its magic to try and keep the jeep moving. It is a jeep after all lol, it's in it's DNA to go off road.

Re: Quadra Drive II vs. Quadra Trac II

Great video. I've been thinking of selling my high mileage WK QDII and getting a WK2 V6 QTII. After watching this and other videos, plus my own experiences on Jeep Jamborees... Thinking I just might keep it!

Re: Quadra Drive II vs. Quadra Trac II

Good info in this thread. Thanks to the contributors especially Biggie for the video in post #16. (Biggie, Latham is my hometown, BTW!)

At first on reading this thread I was bummed that I did not get QD-II on mine but the explanations here helped, and I know that I'll be okay in almost all situations having QT-II and not QD-II.

Quattrojeep thanks for resurrecting this thread. I may not have found it otherwise.

Re: Quadra Drive II vs. Quadra Trac II

I bought my Jeep Grand Cherokee from a dealer 250 miles away from me. They offered way better incentives than my local dealer.
When I started corresponding with them I specifically told the sales person I wanted one with Quadra Drive not Quadra Trac. When he sends me the vehicle info I called him back and told him it was not what I wanted and repeated myself. He told me it had the offroad adventure package which included quadra drive and emailed me the info on that package.
So I finally drove up and bought the JGC. I chould have done my homework better because I ended up with an Overland with Quadra Trac.
I am so pissed at the sales person and that dealer that does not train their people properly on the products they sell.
The sad thing is if a knowledgeable sales person had educated me on the differences I might have chosen quadra trac anyway; but, I was not given that opportunity.
It is a comfortable vehicle, but I'm still pissed!

Like many who post here you didn't give much info on your vehicle. AFAIK - QDII isn't available with the V6 and would be standard on an Overland with ORII with diesel or Hemi.

That's it in a nutshell: cannot get QDII with a V6. Not standard, not an option.

Re: Quadra Drive II vs. Quadra Trac II

The available 4WD drivetrain options for current model years of JGC are: QT-1, QT-2 and QD-2...or QT-I, QT-II and QD-II if you prefer Roman numerals. And yes, for those trim levels that offer QD-II, it's only available for Hemi or EcoDiesel.

My guess is, people who would be doing the type of offroading that would really benefit from the QDII system would be more apt to want a larger engine with more low end torque.

Torque is your friend when crawling.

Absolutely. That is precisely why it's only offered in Diesel and Hemi (the two options of most torque offered).

Re: Quadra Drive II vs. Quadra Trac II

This is peeking my interest.

Can anyone point me to a good source that explains all this?


Cheers,

I would agree with that if you were looking at QD in its original versions.

QD originally had the QTII TC and used Vari-Lok progressive front and rear diffs. That system split power front to rear and side to side so any one wheel could receive up to 100% of the power.

The second version of QD switched from Vari-Lok to front and rear ELSD's.

In both of those versions I could understand it only being available with the V8.

Today's version of QD is basically QTII with an open front and ELSD rear. It relies on traction control to help make up for the lack of a front ELSD. I fail to see how the 3.6L wouldn't be capable of handling a rear ELSD.
