Does anyone know if its possible to modify the AWD system so that it doesnt switch to RWD from 16mph or whatever that cutoff is? I find that a bit too low....

 

do you really make enough power to spin all 4 at 30mph? or even 20mph?...

 

Let me clearify...im talking about severe weather. snow and blackice. I want it to stay at 50:50 or 25:75 or at least raise that 16mph cutoff...

 

Hit the snow button... splits it 50/50 and make throttle less responsive so u wont spin to lose control.

 

only until 16mph. I want this at higher speeds. I dont know what infiniti was thinking by making the car RWD after 16mph. not that great in extreme conditions like we have in Canada. i am always slipping, thats WITH studded winter tires on. Its bad enough that I am thinking of selling the car and buying a 4matic c300.

 

You do realize that AWD will engage when tire slip is detected, regardless of speed, right? It's not like a light switch, either on or off. The Benz 4-matic system is a joke compared to the capabilities of Nissan's ATTESA system. Subaru's AWD on their automatics is a close second to the ATTESA system.

I dont know about that; I test drove a 4matic and a 3 series with X drive and they felt much stabler on the snow compared to my infiniti...
my car slips and just cuts off the power. Instead of engaging all 4 wheels. so you are stuck going no where. At high speeds, this is a major problem as your car is running on RWD and only becomes awd when slip is detected. thats just flawed because you can easily lose control of the car before your car tries to fix it. I believe theres another post regarding this by another user a while back.

 

hmm no. snow button = 50/50 all the time.

 

It sounds like you've got either a tire problem and/or you're driving too fast for conditions. The AWD is your X is more than capable of reacting to a slip situation quickly. The system samples wheel speed data 10+ times a second. All AWD systems act like the one in your X. They either operate entirely driving one axle until slip is detected or they run some sort of initial power split and vary it from there. I believe the system in your X is 5% FWD and 95% RWD until slip is detected. My wife's Outback operates in in 85% FWD and 15% RWD until slip is detected. When driving in snow and ice, the wheels are going to spin even with 4WD or AWD. My Subaru's spin the tires quite a bit in the snow, but that doesn't mean they're going to get stuck. Some slip has to occur in order for the system to engage. Without slip, you're not loosing traction. The system can't read into the future. It sounds like you're basically wanting is a true 4WD system which you're not going to find in anything but heavier duty truck or SUV. I would think someone would have to be pretty dumb to get an X stuck in the snow with snow tires. I've managed to drive my RWD through 5 Midwest winters on all season tires.

BMW's X-drive operates in 40/60 until slip is detected and can route power 100% to either axle. Your G can do the same. The advantage of the G's system is that is has RWD handling dynamics which is typically seen a good thing. The BMW is going to feel like an understeering FWD car in the dry.

 

It only goes up to a certain speed and I believe it is less than 20mph. After that, it reverts back to normal operation.

 

maybe its because my tires are brand new... I will monitor this and see how it goes :/

 

really? thats weird.
I usually use it on bad down pours on HWY speeds. where there are water puddles everywhere, and car feels 100times more solid and in line when its turned on.

also OP. what kind of tires are you running?


to compare Xdrive or 4matic to our Xs i think our Xs do as good or even better then 335x, or 535 xdrive I've driven plenty of times, and 4matic on c300. C300 just doesnt even feel powerful enough to lose its end to begin with, and C300s interior made me want to get out of the car after 30mins of driving. Too small, and no comfort zone. I'd rather baby a fast car, then be stuck in a uncomfortable, slow car. lol

 

i got studded altimax arctics...

 

yeah thats very true...benz didnt use the best material in the C class...looks pretty cheap...

 

3series over c300 anyday.
and since 335xi isn't worth the lease $. thats when u turn back to g37xs =]
