Good presentation.....allow me a quick question.....so the ( partial AWD system like on Sienna) system is basically always in front-wheel-drive mode and the extra-2 back wheels kick in when needed....OK. Is there a common problem we can check for, if the dash warning comes on? Reason for asking....my son-in-law has this car and the dashboard warning came on, on his 2016 Sienna.... about an AWD problem ( one warning says "Traction Control Off",....the other is "Check AWD system"...and the CEL light came on, too). Is there a "typical" , first-round check that we can do, that may find the cause? Car was never towed .
I noticed even the E Awd puts down power to the rear first then does a front power fill when in dry conditions. Really helps the car squat while letting the nose rotate. Impressive system for a SUV this size
How much better is the torque vectoring awd vs torque control? Is it worthbit to jump to higher rav 4 models to get the torque vectoring awd for snowy conditions?
The new hybrid Sienna uses the same system as the Highlander Hybrid. The previous generation V6 AWD Sienna likely used the same system as the lower trim Highlander AWD systems (no torque vectoring).
Question to Toyota if there is any software update to solve below issues with i-AWD? czcams.com/video/oIaqkuVuXtg/video.htmlsi=wEkGZhMdQPJriUNy czcams.com/video/BhxCJH4-uxQ/video.htmlsi=FIzNzIjYYsYcPhdy
I got a 3.5 inch lifted Toyota Sienna XLE AWD. AWD systems are still inferior to Grandpa's old 1940s 4wd solid front and rear axles with shifters and hub locks. Just cant improve much on hard metal gears, axles, and transfer case perfection from Dana 60s and New Process...and equally important.....ground clearance for off road. Or overlanding. These high tech lady systems just do the driving for the soccer moms and suits heading to the office.
The AWD is total JUNK!!! Just now got stuck in the snow an all I got to spin is the front tires!!! Not even the back breaks worked. Its 2018 25k miles on it!!
I'd be fine going with your take if I hadn't driven all these cars and shot video of me driving in the snow. Yes, any car can get stuck in some situations but overall, Toyota's AWD makes driving in varied conditions safer and more reliable (from my experience). The thing is, especially if you live in a region with snow is, what tires do you have? That's a big deal that most people ignore.
@@WhatdrivesUs yes tires sucks. They problem is this is a Hybrid an no down hill button like they have in the platinum which everyone says good stuff so I think I will trade for the platinum an get away from Hybrid.... I was wrong to say the awd is junk its the Hybrid thing N tires....thank you
I have a 2013 Sienna AWD. I got stuck this winter and the AWD didn't engage to get me out. Finally had to chain up the fronts with diamond chains and pulled right out. The only time I see it working is when you're starting out on dry pavement and you're turning (like pulling into traffic). The rear axle kicks in and you're good. I was hoping to learn more about the Sienna system here, but it was omitted from the discussion.
Yes, I did (russell here). And it won't surprise anyone to hear that they are not interested in leading in this product category and are waiting to make a profitable car they think will sell in large quantities. I get it's not the answer we want but it's also legitimate from their perspective. I'm not saying anyone has to agree with this but you have to respect it as an answer. I have again, this last week, expressed the idea that, like during the time of the Prius, they could help lead this change over to BEVs but they resist that while acknowledging yes, during hybrids they were a leader. Toyota feels they are doing their part in partially electrifying their fleet so more people can drive more cleanly with their vehicles and, they have a point here. This position of theirs on EVs is entirely consistent with the way they have viewed them for as long as I have been in this field. I am obviously paraphrasing. I have no intentions to put words in Toyota's mouth. Personally, I think there are three reasons people harp on Toyota about electrification. 1-They're the largest 2-They led with hybrid Prius 3-(and maybe this one is just me) I think people really want a company with the reputation Toyota for reliability and affordability to build a BEV
@@WhatdrivesUs Russell, thanks for the great video. Really explained the systems well. It seems to me that Toyota has been developing all the BEV pieces -electric accessories, batteries, AWD systems, - on the hybrids. When it is time to release a BEV, they will have all the engineering in place, just add more battery. The Prius Plugin gets like 75 to 100 mpg in typical use. In terms of gas use, compared to an ICE, it's practically a BEV.
Now with the RAV4 Prime out soon and it’s limited availability due to lithium battery shortages I’m betting Toyota’s commitment to Fuel Cell is a long term chess move.
I got it in my ‘21 Highlander. With snow tires it’s real good.
With the second AWD system described, why are there two dog clutches? This seems redundant as one ought to be sufficient whether to turn the axle.
Awd malfunction 2wd engaged how to fix
Hey Russell , if I were to email Tom in regards to a question I have about a Camry AWD system that I am researching, how would I reach him? Thanks

Hello help me..what position need stay the floor handle shitt for regul drive I moved but I didn't n remember where it's before
How come on my 2020 Toyota highlander limited awd, the torque vectoring only works on sport mode when at high speed but not in normal mode?
Why e-four is keeping slipping when 3 wheels are on roller tester? The power seems is not delivered to the wheel which has traction.
What does a Toyota Sienna AWD use?
The new hybrid Sienna uses the same system as the Highlander Hybrid. The previous generation V6 AWD Sienna likely used the same system as the lower trim Highlander AWD systems (no torque vectoring).
@@TheEmpoleon123456789 ..Thank you
Top brother in awd
Can we turn off AWD ( if we don’t need) in highlander XLE gas 2022 to save gas
its already off. these part time awd only turn on when you slip
Have this guys heard about "Sienna"? Not a single word about it , table does not show it either.
Can he please tell us why it cost $750.00 - $ 900.00 to just service the AWD front and rear tranny with new transmission fluid !!!
Rav4 2017 bro
I wonder if any of the torque vectoring tech was co-developed with Mazda.
Toyota and Subaru work together. Mazda no,no,no!
I get it better now
Is that Billy Connelly?

My 2018 RAV-4 AWD worked so good, that it was unusable. Most hopeless system in snow that I had ever owned.
Really? Ive seen some videos where it seems to do pretty good. What model rav 4 do you have?
Facts it’s terrible
@@lilpeppa117G wow. I'm considering 2024 rav 4 vs subaru outback.
@@lilpeppa117G
Fact is that if you can't be specific about why it's terrible means that it functions just fine 😉

You comparing apples to peaches! Total different technology 4WD vs AWD.
Plenty of soccer moms out there just raising their families who just need something that works
mmmh ...??....just thinking the subaru awd is the real deal...period!

@@tomkruger3496 we traded it in for a XC90 Volvo OMG sooooo much better ride!!!!
@@tomkruger3496 you need better tires then! If you put chains on your tires and you got out. It's caused by bad tires.
did you ask any of the Toyota people why they are ignoring BEVs when it has been obvious for years that EVs are the future?
^ This!
