Getting used to No 4 wheel Drive Auto

all good. I'm from east coast of Canada where I learned to drive on freezing rain, black ice, snow, and just general crap. Spent time in north where usually too cold to get much snow. Time in snow belt of Ontario where 2 to 3 foot dumps were common. So from all that I learned that 4wd is best to get out of problem, not so much to dig into problem.

Now live in Oklahoma. Rare snow but ice can be common. Auto 4wd would be sweet for ice I think because shouldn't engage 4wd on pavement. But I still like this truck. Thinking when get to time for replacing SUV might trade for the new Rav4 awd. Looks awesome. Peppy fun car, great on gas, and awd.

 

For me, having 400 hp and 500 tq, and coming from a Tacoma which is pretty gutless, I use 4A anytime the road is wet. Just helps so much with keeping traction. Used it last night in fact on the way home from the Wife's firm Christmas Party. Was raining cats and dogs. I also use it any time I am hunting because the area I hunt is a mix of tarmac and fields. Just set it and forget it.

 

Traction control and good tires have been fine for me in several different trucks on wet pavement for over 20 years and I've never really understood other peoples' need for 4wd/awd in that scenario. I run into issues with spin when I am on cheap factory tires that perform poorly in rain or when I am down below the 5/32 range. Aside from that I have never felt the need for AWD. If I am just on damp pavement thinking "I wish I had more traction" it means I was driving too fast or need better or new tires.

 

Haha what a silly way to rationalize Toyota not including this modern feature on their brand new flagship truck.

My tires are fine. I've never been on damp pavement in 4A and thought "I wish I had less traction".

 

you sure like posting pics of your ford, lol, I can tell your super proud of it, which is cool.

I was damn close to buying one but then I had that fiasco we talked about so off the list it went.

 

I think Full time 4WD is a nice feature and I wish I'd have found an F series otherwise equipped as I wanted on the lot with it, but can live without it. I think Toyota made a mistake not offering it somewhere in the line.

I have never seen it as something I needed on wet pavement. I only wanted it because it would be nice on days when the plows are having trouble keeping up to not worry about switching back and fourth between dry and snowy stretches. My long bed reg cab Ranger was garbage on wet pavement and something like that would have been nice. But since then owning Crewcabs with other modern traction systems I just cannot look back on any scenario I've ever seen with damp pavement and remember thinking having both ends turning would help. Driving within the limits of the vehicle and the tires has always been good enough for me.

 

Well was really just trying to show the tires, but that's the picture I had handy. Merry Christmas.

 

you too!

 

Just to be super clear, the Sequoia also has ATRAC. Just like the Tundra, 4Runner, Tacoma, and LX/LC. From that quote, it seems like Auto Trader doesn’t know this.

Having now driven my LX for a few weeks, I don’t miss 2Hi. Might be nice for long trips on the highway, but if I had a 2G Sequoia, I’d probably leave it in 4Hi 95% of the time. Fuel economy is gonna be terrible either way, lol.

 

mass-hole is correct. Too much misinformation in this thread which is typical though for Yotas fulltime 4HI Torsen system. The 2019 Sequoia has:
* 2HI, so RWD with ABS based traction control.
* Fulltime 4HI with Torsen center diff, same as LC's, some 4Runners, Lexus GX and LX. Can stay in 4HI 24/7/365 on any surface, can swap back and forth from 2HI-4HI-2HI on the fly on any surface.
* 4LO, same as LC's, etc.
* CDL button that locks the Torsen tcase for permanent 50/50 split. CDL can be engaged on the fly, same as LC's, etc.

It's a robust system, literally millions upon millions of miles in the various Yota vehicles. LC's, etc are always in fulltime 4HI, no 2HI, so loaded, towing, all surfaces the Torsen tcase is doing its thing. We have two fulltime 4HI V8 4Runners and the Sequoia, combined 500k miles. No problems, slap 75W90 synthetic gear oil in and they do fine loaded, towing, offroading.

As for why it isn't offered in the 3G Tundra/Sequoia, t300 said Sweers was concerned the hybrid's torque could be a problem. I can see that somewhat, but the LC300 has a diesel with 516 torque. I saw a video with another Yota engineer, he said their marketing surveys showed most of their prospective customers don't want it or need it.

I think this is where confusion sets in. Fulltime AWD like a Subaru is not the same as a Sequoia with 2HI, fulltime 4HI with CDL, and 4LO.

 

I didnt say it was identical. It is not, since it has 2 Hi, which is exactly what is said. But it does have full-time 4wd, and that full time 4wd utilized a locking torsen differential starting in 2005, just like the Land Cruiser. Prior to 2005 it still had a differential, it was just a locking open diff.

So what we have here is the full-time case I want, as well as a 2wd case that you want for your MPG's and apparently for increased towing capacity. It's been there in a Toyota for 22 years now.

Straight from the 2022 Sequoia Brochure:




And the best part is people have swapped these t-cases into Tundras.

It is simple to understand.

 

Did your trucks have >400 ft-lbs at 2000 rpm and a 4.7:1 first gear with 3.73's in the axle?

 

I am not sure why you would miss 2hi unless you wanted to get sideways on a dirt road or a snowy parking lot.

I feel like my lexus GX gets respectable mpg for what it is. Its not like they do considerably worse than a 4Runner despite the V8 and full-time 4wd. its a couple 10ths of am MPG according to fuelly. I really dont think it causes that much drag.

 

I am a big 4A fan, but I also have never felt the need in solely wet conditions.

And yes, I have driven many high powered trucks, even before the days of traction control.

 

Umm…I drive a Powerboost with 570 pounds of torque, 3.73 rear and that first gear ratio exclusively in 2wd when it is raining. I in fact just drove it in rain in 2wd to the local track and am typing this in the driver’s seat before i get out to warm up for my sprints. It has rained here all week and I have not even remotely thought about my 4wd switch. This thing has enough power that it is rated about the same as the Challenger RT I just got rid of 0-60 and I’ve been puttering around in the rain in 2wd problem free since March.

 

It almost never rains here, so i cant comment specifically on that, but snow for sure. my 2014 F150 will light up 35's no problem even on dry pavement if I am trying to turn out from a side road and get up to speed. Since almost all of our two lane roads here are 55-65 mph its a common occurrence for me(no lighting them up but accelerating briskly while also turning). I have to really feather the throttle.

 

I didn't know you could get 3.73 gears with the PB, sure you don't have 3.55's?

 

My truck does not spin on dry or wet pavement unless I turn off the traction aids and/or consciously try to make it spin. I can think of a handful of times I got a good chirp in the last few months gunning it hard to get going from a side street across a couple lanes of traffic onto a main road. Driving normally in a way not intended to cause a loss of traction I cannot say that it has happened.

 

All PB's have 3.73's. Probably to give the electric motor a little more twist at the tire.

 

I just tried to build one on Ford's website. When you select 3.73s it automatically deselected the PB. I don't think you can even get 3.73s with the regular 3.5 EB except for the Tremor.

 

It’s a popular request from the family any time there is snow on the ground.

 

axle L6

 

Hmm. Wonder why the website is not letting that be selected. Possible it changed for '23 though I guess.

 

Maybe my perspective is not the same as others. I owned a long bed rwd 3000 pound reg cab compact truck without traction control for 5 Winters (That sucked balls) and drove a 6 speed V8 challenger around in rain for 5 years so it might just not feel like as heavy of a lift for me to get a 6000 pound crewcab on 20s to behave itself in some Water after all that.

 

I want to say I read somewhere 3.73 was actually the only powerboost option in 2021 but I can’t find it now, I’d have to dig out that year’s order guide.

 

Have not read the whole thread. At this point in my life I will remain old school. As I posted before I like the system how it is. Auto 4wd is unnecessary IMO, but I grew up in the north driving RWD sedans every winter. Made it where I was going everytime.
Hell a FWD only vehicle will do just about as well in the snow as a 4WD will. Drive accordingly to the conditions

 

There's so much to like about the 2G Sequoia SR5 4WD. The tight turning circle, about the same as a 4Runner at 39 ft. Just does everything well in Colorado in snow, sand, mud.

 

Slightly off topic - but just watched the TFL review of the 2023 Sequoia Pro showing full time 4hi / 4Auto / Torsen lockable center diff didn’t make it to the new gen Sequoia making the 4wd system now identical to the new Tundra.

 

I heard the powerboost batteries may be problematic. Powerboost seems great on paper, but so do all these new generation drivetrains. Longevity worries me. I don't have a bunch of budget to be fooling around.

 

I was big on the 23 sequoia until I saw the 22gal tank as the only option.

eat it Toyota. A 22gal tank belongs in a Camry, not a 6500lb suv
