Best drive system for snow

Does anyone think there is any significant difference between QT2 and QD2 on snow covered roads?

Unless you're in four wheel low, the results would be negligible. The only difference in the outcome would be your tire selection, and the driver inputs.

Re: Best drive system for snow

Can only give feedback on the QD, but even on our steep driveway with snow and or ice (in snow mode) it drives right up with virtually no wheel slip. Today I tried coming back down (with a good coating of ice), and tried it in Low Range with the hill descent control on just to see how it behaved. Very impressed and you could feel how each wheel adjusted the second it started to slip off line.

Both are great systems and I am surprised how little the folks at dealerships know about these systems. I’m on my 3rd Grand Cherokee and I’ve chosen the Quadra Drive on all three. It is a more capable and faster reacting system but not necessarily worth the extra money. I found the following statement in another post that sums it up for me: “They're both great systems and I wouldn't hesitate in the slightest to get a QT2 rig..... but if given the option, QD2 is worth it IMO.”

Re: Best drive system for snow

Thanks, I think I might go for the QDII as well since I will be spending so much anyway that I don't want to look back and regret not getting it.

In the grand scheme of things I'd go for it too.

I would also add that Quadra Drive is the main reason I got into Grand Cherokees in the first place. It’s what puts a big separation between the Grand Cherokee and regular SUVs. The only thing I’m curious about myself is how well the new version of QD compares to the previous generation QD. They’ve removed true electronic limited slip differential (clutch packs in the pumpkin) on the front end and switched to a “brake” limited slip differential which is not the same animal.

With the speed of today’s computers in cars and the design improvements in the ABS systems, I think the new generation QD has a very good chance competing with the previous generation QD. There may in fact be some benefits that I’m not aware of. It takes quite a bit of reading and research to try to get to know the details of various 4x4 and AWD systems. There’s no perfect system for every driver in every driving condition… everything is a trade-off.

As an owner there are trade-offs when choosing one system over the other and as a manufacturer there are different trade-offs when choosing one system over the other. I try to sort through what makes sense for me vs. what makes sense only for the manufacturer, and like I mentioned before, I’ve gone with the QD three times in a row now. (Go for it )

You can have the best four wheel drive system in the world but if you don't have a tire capable of performing on that terrain you will still experience issues with traction.

Search the forum for thread topic referring to Jeep slipping in winter conditions or not able to drive up small inclines.

Funny how people will spend the extra cash on the "better" four wheel drive system but run cheap all-season tires in the winter.

Totally agree and I"m learning that the scary way. To me anyway kinda ridiculous how Jeep positions all there Jeeps as plowing throw snow with ease, etc and they put the Forteras on the Jeep. For regular driving they are fine, but, come on you need different tires to take advantage of that good technology.

When looking at the various packages - seems like the diesel and hemi automatically get the"QD."

From y'alls experience what is the best "snow" tire - AND - will it also serve as a good off-road tire. Then how about the highway?

Best ice/snow tire. Nokian Hakka 7 or 8 factory studded--nice square studs. Overkill for most conditions.
No, it isn't a particularly good offroad tire, it is optimized for traction and high speed handling in truly crappy siberian grade weather. Noisier than most any other studded tire, but you do not have to slow down except for other drivers.

There is no such thing as a good tire that does everything, but the Cooper winter tires aren't too shabby for everything but hard core offroad.
