That's true, but from what I've heard the QDII system is not the same on the new WK2. It no longer has ELDS in the front axle like the WK and Commander.
x2. This was my point too. It is different and Jeep is not saying anything about it.

Re: Quadra Drive: =All Wheel Drive?

The way it was always explained to me was QT I can adjust torque from front to rear or rear to front if needed and there is no low range. QTII can adjust torque front to rear or side to side (any two wheels) if needed and you get a transfer case with low range. QDII does the same as QTII plus it can send ALL torque to one wheel if needed and you get the ELSD (which use to be front and rear but now in the WK2 it’s only the rear). The best is QDII as the computer is sensing all wheels all the time.

When I purchased my '99 Grand Cherokee Limited it came with a VHS video showing a QD Jeep pulling onto a bunch of rollers (under each individual wheel) and the Jeep spun all four wheels and would not move. When they applied the brakes to one (any one wheel, they showed all four wheels, and the Jeep drove off every time) of the sets of rollers that wheel gained traction and the Jeep drove off with traction to only one wheel. The ONLY (they showed Ford, Chevy, Toyota etc..) other 4WD that passed the same test was the HMMWV (Military hummer) as it is still today “true Full time 4WD” meaning power to both rear wheels and the right front all the time (when the transfer case is placed in LOCK it locks the left front wheel in hence locking both front and rear axles).

In 1980 the EPA said no more Full time 4WD because of the gas shortage so 1979 was the last year for true, for sale to the public vehicle non-computer full time 4WD pick-up truck. The only “true” one today is the military HMMWV because the EPA has no control over the Department of Defense. QDII is the next best thing, heck its the only thing I will drive.

Re: Quadra Drive: =All Wheel Drive?

I found part of the Jeep video that covers one wheel traction test that I mentioned in my earlier post. It does show that a mercedes also passed the test. The test starts about one minute into the video.

Re: Quadra Drive: =All Wheel Drive?

It's simpler to just think of these systems as being one wheel drive until that wheel slips, and then a different wheel, or perhaps two, will come into play to transfer the power. 4 wheel drive is a misnomer...you have two driving wheels at most! In QDII, the limited slip rear diff is retained for the WK2, and brake application is used for the front diff to transfer power. The engineers say it's as effective as previous systems, so now that it's snow weather, report your findings!

No.
You can think of it like that but it isn't like that

Re: Quadra Drive: =All Wheel Drive?

I like the fact that folks are catching onto the misconception of 4WD.

There's a lot of confusion for the average person. So many different 4wd systems and AWD systems out there that I'm not surprised people get confused.
