Re: Best snow driving techniques and modes

there's a couple videos by jeep that are more comprehensive, still could be more detailed and to me kind of incomplete. It's like, OK, that's all you need to know, we'll work the magic.

Re: Best snow driving techniques and modes

Been out today in every kind of bad weather. deep snow, then sleet, ice, and rain on top of that, then more snow, even unplowed roads. This whole thread has been informative and evolutionary for me. I realized that it was more about driving the way the jeep was designed to be driven than trying to force old driving habits on new technology. Results were terrific in all respects. I thank everybody for the help,tips, ect and I was once again reminded of the value of keeping an open mind. The Goodyear Advantages' were outstanding stopping, going, and everything in between.

My situation, too. I got pretty darn confused and frustrated regarding powertrain choices. Only recently did I find out this plain, simple fact: QD-II in only available with a V8 or Diesel. Judging by your 3.6 liter signature, you and me are in the same boat -- QT-II is as high as we can go. Next time maybe!

Re: Best snow driving techniques and modes

right. although I would prefer a locking diff,the jeep is pretty formidable as is. Perhaps that will be an option with the v6 limited by the time I'm ready for a new ride.

Sorry to say, but I don't think so. I have heard that the V6, as good as it is, does not provide enough torque to power the QD-II. Need the V8's or Diesel's higher levels of torque that the gas V6 just can't muster.

Re: Best snow driving techniques and modes

Idiot buy into that one perpster. Overdriven such a wide range of vehicles in snow, sand, mud, rocks up or down hills.

Driving in snow really comes down to physics and the best methods can be seen in the driving of tractor trailers to motorcycles. Slow methodical starts and using momentum. Rather than less slippery terrain you drive slower and let off the acceleration rather than touch the brakes into turns and don't accelerate out of turns, even though this is the standard on dry pavement.

Tires and speed really combine and letting momentum carry you and slow down hoping red lights change to green before all momentum is lost.

HMMVs were great in rocks and sand but terrible on pavement. The craziest thin logging paths I have gone up were in a 4 cylinder Suzuki Sidekick. Small enough vehicle to actually back down and find a spot to turn around. I had a Mitsubishi Montero sport back from the late 1990s that I used to pull a friends Ford from the snow. A lot is about choosing where to drive in the snow or covered dirt roads. I think much of the time relying on 4WD or AWD can actually make things worse as your turn ratio is compromised and one tends to rely on brut force over being choosy about the path you choose. I have light truck tires on the 2011 WK2. They are a bit heavier and it drives like a truck with heavier tired with more weight creating more ventricular force. If it's just your jeep you should be fine but knowing what terrain is under the snow is always helpful.

I've had 3 Subarus with only on being the original 1990 legacy which did well with Front wheel drive. The AWD Subarus have a completely different type of system that have since been leased out to Audi and Volvo. Those cars really do well in almost anything but large rocks. Again that is about choosing the right path through a set of trails.

In the Sand of the KSA they were very much in favor of Toyota Land Cruisers and Isuzu Troopers that had most of the niceties removed but these vehicles did very well in sandy, dust filled areas. In North Africa the Toyota pick up trucks were a common sight with heavy machine gun mounted for use from the bed they were called technicals and while light weight, when filled with a bunch of guys with RPGs and Kalishnakovs these could be a bit intimidating as they showed up fast and could leave fast as well. Even with modernized track vehicles or strykers it can be hard to keep up with these old rigged outToyota pick ups with balloon Safari styled tires. Luckily they usually fled immediately if helicopters wherein route or the armored vehicles were prepared for their arrival. Still one had to marvel at how they kept these Toyotas running in harsh dusty conditions over time.

Not saying I agree the V6 can't power QDII, but am saying that's allegedly why Jeep doesn't offer that combination.
