Agile Off-road test of traction with roller test gear- no traction control????

So, when you lock everything up, it's good- but it appears that there is little to no electronic traction control. Zip. Nada.

In standard high or even in high with center lock, with a single tire on each axle spinning, it won't go.

So this means to me that at least in something like snow/ice, it isn't going to be great. Get slow, and lock things up, sure, good. But I think I'm going to leave it in the garage tomorrow for the drive up I70 to Vail, and the nod goes to the JKL.

100% what I would want on a truck like this.

It drive great in the snow, I just ran up Snow and ice covered Alpine loop, stay in high on trip out and test low on way back, never locked up the center or the locker. Now a Jeep Rubicon 4xe I pulled out of snow bank did not do so hot, Snow and Ice It more about the tires.

Agree with @Dokatd I do not want electronic intervention, you have the tools which what he pointing out to deal with all situations.

Brake traction control has been discussed here. The Grenadier has ETC but the consensus from earlier testing is that it would benefit from improved calibration.

The problem with I70 ski traffic is you go from dry, level roads, to highly pitched up and down with ice and snow- and from stop&go to 90mph. And while you can lock it all up and get moving, you’d have to stop to get out of low and locked.

I ‘m just surprised that there seems to be NO electronic intervention.

I will agree with you that the diff lock situation requiring low range is just stupid. Snow or ice you want open front and locked rear if you're slipping any amount.

All that said, I have driven I70 a ton in snow and Ice. Last time was in a Ram Duely with a goose neck trailer and a 9000lb Unimog's on the back. It's not that bad of a road in reality.

The pass from Ouray to Silverton when it's shut down is a fun road. I snuck through it in my Defender90 back in the 90's. Sooooo much fun!!!

I would like to see the exact same scenarios tested with the stock tire size. If those are 285/75 17” tires that’s over a 5% difference in circumference and I wonder if it is enough to cause calibration issues with the traction control system? The traction control system uses more than just wheel speed differences to trigger the system but also looks a torque load, throttle position and I’m sure some other parameters as well. If nothing else, it would prove tire size doesn’t play a factor but I have a hunch it may but I’m willing to be wrong.

You can lock the center diff in high. You don't need to low. And yes I am being nick picky but I'm in that type of mood tonight.

Yep, you certainly can. And yep you certainly are.

I know it very well I lived in Denver in 90's and used to ski 70 day a year rolling up to Beaver Creek, Vail and Breckenridge mostly from downtown Denver, fun going through the tunnel, all the crazies on Floyd hill and in between in a storm, back then I drove Pathfinder 4x4. Back then you had to go out and lock the front hub, which never wanted to do in winter.

Looks to me like ETC isn’t working at all in Agile’s test. TFL did their slip test when Adam visited and while it was a bit slow, it worked well:

ETC has worked fine for me on unplowed mix of snow/ice going uphill to where we live with the center diff unlocked. ESC lamp flashing at times and didn’t get stuck plowing through. I’ve only been to Vail once in the snow many years ago, so don’t quite remember how it was, but expect the Grenadier would be fine.

 

[MileHigh]

Thanks for reposting that TFL video. I remember when it came out. I think the question on that would be is that the owl video they specifically kept the throttle fairly low, because they didn’t want to over toque the ability of the slider. In this TFL video they use a bit more throttle. I think the question would be is if the stability control is finally kicking in, or is the wheel on the spinner generating enough torque/traction to pull.

My guess is that it’s a bit of both, but definitely the traction control seems to finally be kicking in. One way or the other it’s getting enough traction to move.

 

[TahoeGren]

Yeah, that or something to do with the oversized tires like @C-Mack said.
On hard packed snow and ice, unless you’re on uneven surfaces, tires play a more important role.

Yep that why on my X5 even with it fancy Traction Control along re-biased AWD, 18 month back I chose Michelin Climate 2 a winter oriented All Season tire, strong snow tire, over the BMW OEM Pirelli's which were terrible in snow and ice but OEM is better in Summer conditions. These tire really helped when running around on Sabbatical in Colorado last February and also heading up to Purgatory and Telluride before I picked up the Grenadier.


One thing It is always fun watching Tyre Review on how various tire handle snow and ice. His current All Terrain Tires test was with Ford Raptor ,He did not have K03, only K02, not he did dry testing of K03 earlier on his truck. - BFGoodrich All Terrain TA KO2 (due to Size availability), the Falken Wildpeak A/T4W, the Kumho Road Venture AT52, the Nitto Recon Grappler AT and the Toyo Open Country AT III in the dry, wet, off-road (dirt) and snow -

While taking almost 4 hours each way from home to Vail (120miles), and running into freezing fog and some light snow, the roads ended up being in pretty good shape and I didn't get a chance to really test the IG very much. I had hoped to drive around and test thins out while my kids skiied, but I ended up not having enough time. I thought we were going to get snow here in Denver, but it looks like we won't get much.
