I find 4wd is much safer as far as staying on the road in winter.


That is the false sense of security that 4wd gives people. 4wd is only better going from a stop for traction, not moving a traffic or highway speeds. It is harder to gain control if you lose control of a 4wd vehicle than a 2wd vehicle.

4WD works at any speed, if it is in "4-Hi." A lot of mid-90s Chevys let you put it on. In heavy rain, or snow, it really helps. Just dont ever slam on the brakes, and dont go more than 70.. your tires are barely holding on, in rain. 2WD or 4WD but 4WD helps.

As to 4WD in snow, for the average few inches and driving around the neighborhood after an overnight snow, 4WD makes it like it is not even there. In an SUV, you can drive over ice potholes, curbs.. parking is ridiculously easy.. 4WD is wonderment.

I speak from firsthand experience, so you may say "4wd isnt as good as...." .. Yes it is.

I use 4WD at speeds a LOT higher than 20Mph VERY frequently in the winter.

The rear diff has limited-slip, the front is open.

Unless it's locking diffs, it's not 4WD.

It is still called 4x4 dude. Very few SUV's and pick-ups have locking fronts from the factory.

Since you are such a fan of posting links and articles, here's one for you on the topic:

Quote:
Only few vehicles in the US are offered stock with front and rear differential locks: Dodge Powerwagon, Hummer H2 + H3, Jeep Wrangler Rubicon, Mercedes G500.

On some models a rear differential lock is optional: Porsche Cayenne, VW Touareg, some Mitsubishi, some Toyota.
Other terms used for differential locks are: locker, diff locks, diff lockers, differential lockers

By your logic, both of your vehicles are 1x4 since they are only one-wheel peel most likely.

4x4 and 2x4 are named as such by the number of drive wheels. If I put on 4x4, both my front wheels have POWER going to them, they are DRIVEN wheels.

Just like on a 2WD car, even with an open diff, both wheels have POWER, what happens of course that if one wheel gets on a slippery surface, that wheel ends up with all the power because of how a differential operates.

MANY vehicles touted as 4x4 don't have any sort of locker or limited slip on EITHER drive axle. So again, {removed insult towards member} they would be 2x4, since really, on a slippery surface, only two wheels are going to be spinning.

Luckily, the rest of the world doesn't use your logic and having two drive axles with four powered wheels, even if those wheels are attached to open differentials still means the vehicle is called a 4x4.

Vehicle makers have different variations they call AWD and 4wd they are NOT created equal.

I think these comments back and forth are comparing apples and oranges.

That all being said I love my pair of manual transmission Subaru's AWD with nice torque split (40F/60R on Legacy) and 50/50 on WRX ,LSD on rear and no electronics.

What I've always heard, and just confirmed with a bit of research, is that if the vehicle has a center differential, there will never be any tire slip and you can even use 4WD on dry pavement in that vehicle.

If there is no center differential, 4WD will induce tire slip in turns.

Far from any discussion about Hummers for pages.

Thanks for the notify!
