Re: Unsure about snow performance

I have a WK Overland, and honestly it is the best damn thing in the snow, and I run all-seasons on it. I used to drive the 2010 A4 before my Jeep and honestly I feel that the jeep is more sure footed if not the same as the Audi's quattro system. Trac on, and the Jeep handles like it's on rails. Turn it off, and have a bit of fun . I can take the corner and give-er a little and get the back end out, then I ease off and it straightens up like its NBD.

I'll post some pictures from my snowy weekend (Collingwood, ON) in another thread.

Re: Unsure about snow performance

Only time my '11 Overland with 20's kicks out at the rear is when I step on the gas while changing lanes. The median you cross has snow on it so it slips on there. If I really hammered the pedal I bet I would fishtail out of control causing an accident. I've had a couple of scares doing that. Scariest moment was when we had heavy snow last week and I decided to pass a slow car. I had to go in the snow covered lane and while doing so the deep snow almost pulled my Jeep into the 3 foot concrete divider.

Tips:

When passing, let off the gas, change lanes, then accelerate. Don't accelerate hard while changing lanes over snow/ice...you will likely lose control as the Jeep spins out over the narrow area of snow/ice as the traction control doesn't kick in instantaneously .

I noticed that it's a bit different then my '06 Overland...it felt a bit more sure footed but I had better tires then the 20's which seem sporty in terms of traction on the new Jeep

Anyways, the different drive behavior comes with it being a different vehicle. Yes it's a Jeep Grand Cherokee...but it's a complete redesign...so that means it has a different drive that needs to be respected.

Re: Unsure about snow performance

If people don't like the rear end kicking out a bit, they should have bought a fwd based crossover... yeesh

I also have older model Jeep - 04' Overland with QD1 and run 6 years old Goodyear Wranglers in Wisconsin's cold weather. I like to play with the Jeep but have hard time to kick rear end around. Front just grips the road and go where you turn the wheel. Looks like there is different torque distribution front/rear on the WK2 - more like rear performance set up.

Re: Unsure about snow performance

Sorry to start this again.

First, I love this Jeep except for one thing....diving in snow.

This is my 4th GC and I really hate to say this, but it's the worse one for handling in snow. I even have 18" Blizzaks and it does not give me any confidence when driving it in bad weather. Like others have noted, the rear slides out too easily and even simple tasks such as moving off in a straight line slowly, the rear slides out a bit before the front traction kicks in. I tried it in snow mode and no difference.

The quadra-drive II should do well so it might be due to the WK2's weight and/or the relatively wide tires (265/60-18).

We've had lots of snow and extremely cold weather recently so I've had lots of opportunity to try this 4wd system. On Saturday I drove home by highway in falling snow with uncleared roads in my Audi A4 Quattro on snow tires and it felt so good as if there weren't any snow on the road. I did the same trip yesterday with the Jeep and it felt "nervous" at highway speed. So far I want to blame the tires.

Sorry for ranting....just a bit disappointed.

Do you think the lack of a rear ELSD is part of the reason?

That's kinda disappointing to hear, I'm running the last 50km on my jeep before the warranty runs out then trading it in on a new 2012, hopefully they fix that for the new model

And I totally agree with the audi comment, I've got a 2010 A4 and it as well as my 07' before it are unbelievable in the snow

He has the rear ELSD, it's part of the 5.7L upgrade which gets you QDII on the Overland.

Some of what you're feeling may be due to the higher CoG vs, the All Road, but that's a wild guess. But it sounds like the rear bias is higher on the $WD system. The WK2 is based on a RWD platform, the Audi as a FWD platform. Just another wild ass guess.

QDII has ELSD in both front and rear as far as I know. That's why in theory, it is the best AWD system that Jeep has ever made.

Re: Unsure about snow performance

I'm pretty sure Snow mode puts you in a 50/50 torque split.

In my experience in the snow, the couple of times I forgot to switch to snow mode, it was very obvious in the first turn I made. Like you said, rear end wanted to come out.

When I went into snow, it felt much more solid and I don't think the rear came out once. And I'm sitting on stock tires as well, I can't imagine having problems wearing Blizzaks.

NB

Re: Unsure about snow performance

I can't speak for the new Jeep, I've never been past sitting in it at the showroom. I have the 07' overland diesel, and as far as footing in the snow goes I don't feel any less safe than the audi, and I'm running all-seasons on 17's. Wish I had a video camera, took a left-right-left-right round S turn up north sideways, had control the whole way around. Even with that low end torque that the diesel puts out, I never feel like I'm fishtailing when I goose it, it's actually a lot of fun to drift around in lol
