Running 4A all the time?

[Boxer4]

Besides gas mileage, is there any known issues with running 4A in Normal mode all the time? Thanks

I wouldn’t in the summer because there’s no point. But if you live in a climate that gets snow, in winter i would set in 4A and leave it.

Just more wear & tear on the transfer case clutches.

I live in north central Wisconsin and I have 4A on my Expedition and I have never ever turned it on. I’ll use the 4H if I need a bit of help getting unfloundered in the snow.

In the few new Fords that I've driven with 4A, I avoid running it. I hate the way I can feel it slam the transfer case into gear when it starts to slip. If I know it's slick out I just throw it in 4H and run that way.

Definitely northern wisconsin winters

I used to put my old silverado half ton in 4A all the time in the rain. It made pulling out in traffic and getting off the line in the wet much quicker and confident in a pickup with a light back end. I haven't had a 4A in a long time, but I'd imagine it would be the same. 2wd most of the time, and when you need it, it'd lock in the front just when you'd slip a bit. Then it's back to 2wd.

To each their own, but it's a great feature to not ever take advantage of. I loved 4A in my F-150, particularly on wet days.

4A is one of the reasons in getting a Bronco over a 4runner. My xterrra is part time 4WD and my first 4x4 vehicle, but that RWD by default thing killed me as someone who learned to drive in CO winters with FWD instead. Based on my knowledge you'd only ever engage it when you know the roads could be sketchy, which happens constantly in the mountains here, but if I know the roads are mostly fine I wouldn't use it

I found it interesting that the Sport mode set it to 4A

I use 4A in my pickup when roads alternate between snow covered and partially snow covered. Other than that, I like to make the decision as to whether it is 2wd or 4wd.

I run my F-150 in A4 from October to April (snow/ice) and during the summer in the rain as it likes to get tail happy in the wet.

Of course it does... it helps to keep putting traction down when you're givin' 'er the beans.

For really aggressive, dynamic driving, that's when you want AWD as well...

These systems aren't necessarily about wet conditions... it's about slippery conditions... and something is "slippery" whenever the force being applied exceeds the available friction/traction.

Want to keep accelerating and clawing your way through corners to overcome understeer from a RWD vehicle? Enable AWD.

The Sport 4A mode definitely has a “ heavier “ feel while driving.
Normal 2h ( 2 door Sas ) feels more nimble and responsive.

The best part about this is the drastically different driving style necessary to maximize the potential of AWD over RWD when driving anything over six tenths.

I digress though, it's not as if even 2% of drivers on the road could actively identify the different braking and throttle methodologies necessary for AWD/RWD driving.

There are 2 pedals for a reason, because you have 2 feet. Good enough for the DMV, good enough for 98% of drivers on planet Earth.
