Does it actually defeat everything though? I tried this, granted several winters ago, and even with both turned off wheelspin was still limited in my 2012...couldn't get through the pile at the end of the driveway.

I'm still not convinced there's not something else besides TC and Stabilitrac in the mix...

I regularly see any of deep snow,  muddy field conditions, in loose sandy soil conditions and firm but slick and wet snow packed road conditions have always thought it works as advertised.  (It's not hard to get stabilitrac to re-engage if being aggressive with wheelspeed)

 

The time I get in trouble is remembering to put it in 4wd when I know I'm going to navigate a muddy field location, but forgetting to turn of the TC until it starts to bog down. :banghead:

 

 

What I've also encountered is torque management (with the Dmaxes) protecting the drivetrain in dry, excellent traction conditions.

Method hasn't changed.

 

Press and release will shut of TC -  and display a message saying so and turn on the "no TC' light

Then Press and hold, and Stabilitrac will shut off -- and display message saying so and turn of the "Stabilitrac off" light.

yep, I confirmed this last night. my 2015 allows me to disable both "features". I was on lightly slippery roads and was able to fishtail like normal with no nanny systems in my way.

I've done that with my 2012, it will still try to pull throttle out to limit wheelspin...even with both off, confirmed on the dash.

Yes. It says its off until the wheels spin then it powers down until you're really stuck! Pretty sure the only way to shut them off is to put it in 4 low.

really... now I will have to try that out to confirm. I only fishtailed around corners in town going less than 20 mph. So maybe it limits your wheels to a certain speed and I did not hit that limit.

plenty of snow here to play on now. Got 8" this past week with more coming tomorrow.

Mine will keep me from digging out the end of a driveway (think deep snow, very slow wheel spin).

The reason it's such a hot topic for me is that it left me hanging (literally) in at the end of a driveway halfway in the traffic lanes...wouldn't let me use the throttle to dig my way out. Didn't get any flashing lights, nothing other than deadened pedal and you could tell it was trying to keep me from spinning. That was 4hi...

My normal 50 minute commute took me over two hours tonight for an inch of nothing...I really wish my fellow man would LEARN TO DRIVE IN SNOW!

I am not sure if I would consider purposely slipping your torque Converter up to 70%, "protecting the drivetrain". It hurts your TC, but gives peace of mind to the General so they aren't warrantying busted DS's and spun splines. Again, offroading with these trucks is nearly impossible with these systems. Without ABS, you can bind your brakes on a muddy hill and it will pile up mud in front of your tires to stop you, with ABS, your wheels go rouge they wont lock up causing you to just roll down whatever surface your on. SC will cut your power if you start to kick out going up a muddy hill and with brakes that wont stop you because they wont lock, you are sliding back down that muddy hill backwards. Been there, scary. While aids save you on the highway, they try to kill you offroad.

That's not how torque management works.

I experimented a bit more this weekend in the snow. When turning off only traction control, I could not do a donut without the computer trying to correct for me.

 

Then I turned off the stabilitrack along with traction control and could do multiple donuts without stopping and the computer did not interfere at all. Rear wheel speed was 20-30 mph. I know the stabilitrack turns off at 35, I have watched the light. Keep in mind this was all in 2WD. I realized after the fact I should have tried it in 4WD. There's always the next storm.

 

also fun note: my almost 3 year old daughter was along for the ride and she said i was "turning around fast"

I too played around this weekend...Erie got 50 inches of snow.

Turning both off still nets me a reduced power/limited wheelspin scenario...I cannot completely disable the system...

I turned both systems off and was doing 2wd and 4wd donuts without trouble. I wasn’t really paying attention to the speedo, though.

      I have thought an EV might have some practical value in extending the life of the ICE members of ones fleet. Now....I'm convinced of it. I've been letting my better half access Raven (Mitsubishi Mirage) for her needs while Dizzy has been in the shop. Being the fuel freak I am and given the fact Raven is capable of over 60 mpg in clean air on a warm day I was taken back by the wife's ability to take a car that had used a half a tank of gas that to that point had returned a value of 57 mpg and return in with a decimating 51 mpg for that same tank in that same day in a 15 mile round trip of short hop errands and a stop in the drive through at Micky D's.  😱   Trust me on this. It would take the remainder of that tank driven on the highway to return that tank to just 54 mpg. This is not a Mitsubishi issue. This is an ICE issue that is magnified in vehicles capable of such high fuel economy values. On a percentage basis your 1500 does the same thing. Short hopping an ICE consumes a good deal more fuel and in doing so provides zero additional useable outputs. That entire volume of fuel is wasted in diluting the cylinder walls oil films, creating crankcase moisture and acid content and the resultant wear.    Enter the SLATE. All of that is avoided and the ICE's advantage in range and made useful at reduced wear for your ICE!   Kind'a cool.

      Back in the day people would buy cars based on performance. The charger posted does 0-60 in 3.3 seconds. And it’s fully loaded.  It has a decent warranty and will fit most anyone’s needs. Remember the original Hemi? 90 day warranty. 25K mini truck or that car? I’d go with the car. It wouldn’t fit my perimeter. If I could just talk my wife out of her Genesis. It would be perfect for her.

      Let's pivot this back. Someone said they wanted pictures.   Even better, there's already video. Pre-prod prototypes are already on the road and they're letting the press drive them.   JerryRigEverything did a good review. I really enjoy his content and EV adventures, so I was thrilled when he had the chance to review a Slate:

      The Charger EV was stillborn. Wrong car at the wrong price for Dodge's intended audience. Now at a good price with fire-sale discounts, and still not selling, it's still very much the wrong car. Again, Dodge's intended audience. I believe a lot of Stellantis' EV blunders were all under Tavares' regime at Stellantis...the board convinced him to move on. Neat car, just wasn't received on the level that would sustain mass production.   Dodge is headed in a better direction for its core business. I didn't think there was anything left to get excited about re: the Durango after its 15 year run, but they're just now releasing a 392 version that should price out in the low 40's. Nicely done. I'm not sure I would touch anything Stellantis makes with a 10' pole these days, but the Durango is still mostly parts designed like 3 parent companies ago so maybe it's still OK?
