The main difference I have found between 4H and 4 auto is in what happens when decelerating. In 4H, the drive train is locked together allowing compression braking front and rear. 4 auto, only keeps the front engaged when tire spin is detected, meaning in a deceleration condition it shifts out of four wheel drive leaving only the back tires to take the full load of the engine compression braking. This will often result it the rear end sliding out and loss of vehicle control. My rule is to use 4 auto only in mixed road surface conditions and 4H on roads that are completely snow packed.
William Ward A breath of fresh air... Someone who understands the different purposes for the different modes. Auto for patchy/mixed conditions where you can't leave the t-case locked lest it bind up. 4Hi for consistently low-traction surfaces.
William Ward the vehicle should only ever engine brake when you tell it to by manually downshifting. This is why vehicles coast when you let off the gas and the tac drops down to say 600 rpm until you step on the gas again.
Steven Vanheel In an auto with a lockup torque converter, it won't drop to idle when cruising with the TC locked. Coasting is also not universal to all autos. Those designed for towing or performance tend to have more engine braking built in. Silverado diesel with the Allison is an example of a towing-focused transmission with very little free coasting and a heavy engine-braking bias.
Man, I never thought of that. Makes perfect sense. I was considering trading in my 4wd Tacoma for a truck with auto 4wd for mixed conditions, now I'm thinking it may be best to stick with the 4HI in the Tacoma.
William Ward It probably has more to do with the front and rear axles being locked together, which prevents too much or too little rotation in a variety of conditions, which greatly improves stability.
These father and son seems like best friends, so great to see. Two geeks doing what they love with who they love...so awesome!!!!
All season tires are garbage especially in winter conditions. Take it from a Canadian, that also builds tires for a tire manufacturer. Don't risk it, get winter tires.
yellowbe2003 on top of that, continental tires suck ass big time. Had those on my expedition and they were total junk!
Mr223wssm oh really, i believe it. They were probably alright in the summer on pavement though? But other than that.....👎😠
yellowbe2003 Depends on if studs are legal where you live. Most of the US, studs are illegal. The only benefit of true winter tires are that they accept studs or come with them.
Otherwise; they are terrible at high speeds, terrible on pavement, rot faster.
Proper all seasons often outperform studless snow tires. In areas where studs are illegal, you are better off with a quality all season rather than comprimising and getting snow tires.
Unless you are running Michelin LTX Defenders M/S - amazing tires and they do awesome in snow.
FCFordLord
Stop spewing BS, idiot. Regular Winter tires are all nearly anyone needs for winter/snow/ice driving.
Studs are not needed. And Winter tires _are_ better than all-season tires in winter driving conditions. It's the soft rubber and sipes, moron. Get educated.
Biggest issue I experienced with the auto setting on my 2011 Silverado was it felt like if you coasted around a corner in auto mode, the 4WD would disengage which would lead to it basically acting like a 2WD truck and plowing through the corner. In 4 high it definitely behaved better in that situation.
Wow, 70k plus now and all they give you is a 5.3? Sad times.
5.3 is most common option even in that truck.
you can get a 6.2 too
Don Leamon i wouldn't complain about the price because around 70k is the base price for a expedition
Ok, but I hope that for that price, GM has upped their quality/durability quadrant a bit, cause our last Denali XL (with a 6.0) was a turd and the Dmax I just traded in yesterday on a '16 Power Wagon ($46k, which is a lot more truck, at least mechanically) was also imploding. Ram will probably be the same way ;-)~
2017 zl1 camaro/2017 camaro fan noooo not true at all, if you spec it out it goes up to 70k + but base price is 50k or less.
I'm pretty sure that Andre's cold weather prep should just be a ton of vodka.
Tommy always has fun and keeps is fast pace!! Love it! Tommy rocks again!!
Thanks so much for this video. I had wondered about this in my 2015 Yukon SLT! You guys are the BEST!
Fun timing as we are getting snow right now in Va and it's the first snow since I purchased my 2013 sierra almost a year ago. Used auto for the first time last night. Never had a vehicle with that before or traction control.
If there is a pavement, you use 4 auto to keep it from binding, if there is a slick surface you use 4hi. It just locks the transfer case
I kind of wish they'd do what they do in the Duramax Colorado, in making the locking transfer case via a separate button on the dash. Unless you are 100% in snow, mud or sand 4 HI is kind of worthless and will damage the vehicle if used on solid pavement. 4 Auto is quite good anyway.
Scott Wilkins you get it in the Canyon.
Can you explain 4 Auto more?
Alisha it is a rear wheel drive biased system that. When it detects slipping it sends power to the front.
Alisha it's like All wheel drive
Love the suburban. There is a company in Florida called Duraburb Inc that swaps the duramax into any suburban making it completely "turnkey" I wish the duramax was an option from the dealer like the diesels were in the past but glad duraburb is making it happen. Good video guys!
Kyle Riegle reminds me of the old Ford excursions with the 7.3l diesel.
Kyle Riegle the suburban is one of the least reliable vehicles made... And I like Chevy.
Generic Name I grew up w the suburban and still have an 07 they're great and very rarely have problems in our experience. they are reliable up to 200k from having them since the early 80s
Kyle Riegle you'd think that would be a factory option...hell it was before right
Mel Laknanurak they make a 2500 now if you go to their fleet vehicle site
I believe the intent of the 4-auto mode is for patchy icy roads. Normally, it's driving in 2wd, but shifts to 4wd when it detects slippage. Personally, I like to select either 2wd or 4wd myself instead of having a computer pop it in and out whenever it feels like it.
It costs over 70,000 dollars and it doesn't even come with 4 low. But at least it comes with the nifty secret compartment!
You get a 4 low range if you order the upgraded trailer tow package.
Or request g80 option automatic locking diff
my 2010 has all 4x4 modes
Excellent video. I learned quite a bit.....I especially have learned through the comment sections from individuals who have knowledge and experience, thanks to all!
I love these kinds of videos, great job boys
+Emeka Ossai Thanks!
Good job guys. I assumed Auto mode would be most useful for pavement on days when the snow or ice are patchy.
I love these videos!! great job men.
Great video. Good to know the auto setting works well. Gm recommends 4H in ice/snow as I will most likely go to
I'm 55 and I'm on my 16th car. I've had Buicks Oldsmobiles and Chevys, Fords, Dodges and a Plymouth, a few Hondas, a couple of Volvos, and a Benz. There was a twenty year period where I wouldn't have considered another GM product but in the past year I've had the opportunity to drive four new GMs, a Buick LaCrosse, a Caddy CTS, a Chevy Silverado and a GMC Canyon. I'm extremely impressed with GM's current crop of cars. All performed incredibly and each one was precise and extremely solid. Solid counts allot for me. I'm glad to see that GM is back not just in sales but in quality. They're a legitimate player again.
You guys showed my dream car
excellent vid. lets see more like this when available
Great test! Thanks! 🇺🇸
At the end he said my favorite feature of the all new silverado😂
Hi guys, greetings from Costa Rica, Central America. Excellent video. I have a 1998 Yukon with Autotrac and it helps very much in wet asphalt and/or tight turns. To be honest, it's not like a permanent four wheel drive system because it's a reaction system, but works well. The problem with the permanent four wheel drive is that you can't lock the center differential in 4 high, you must have it in 4low, the only exception that I know is the Lada Niva that has 4high, 4high lock, 4low, 4low lock, it's perfect.
Cool video! I love the Conti Cross Contact as an SUV/light offroad tire but here in Austria it does NOT qualify as a snow tire and I would NEVER use it in real Winter conditions. I have Bridgestone Blizzak winter tires mounted from Nov-April (the mandatory months for snow tires here). The Conti is rated "M+S" but does not have the snowflake symbol. Real winter tires have these tiny teeth grooves.
I'm so thankful that I live in Phoenix!!
Great review!
Great vid guys!
Tommy, tut tut. No shame in calling Roman your dad. He seems like a great dad :)
Fun video, thanks guys!
Nice and here before 300k subscribers!!!!
Congratulations
The DWS 06 is a really good all season. Does great in snow.
Great video!
Great video. I have a Suburban LTZ 2015 . Greetings from Germany
Recently rented one of these while in Jackson Hole after a snow storm. The roads were 70% covered in ice and packed snow. I started driving it in 4 auto but soon changed to 4H because it always felt like the auto was a second late on switching power to the front. I could feel the front end binding on a few turns which didnt bother me since it was a rental but even if this was my own vehicle I would have been fine with the occasional bind over the butt puckering feeling of a 3 ton vehicle full of people I love getting sideways on unfamiliar roads. The truck itself is unbelievably nice though. So much room. So many gadgets and tech. So comfortable and quiet yet powerful and really handsome at all angles. We drove down a road that had about 6-8" of fresh snow on it and in 4H the truck never skipped a beat. If I had 70k burning a hole in my pocket and needed to move a family of 5 or 6 and all our gear this would definitely be the truck for me.
This storm was nasty. Wish I still had my 4x4 Jeep, but had to make do with the Miata on Blizzaks. Had that sliding sideways issue you had going uphill, but never got stuck in 10" of snow.
The ending made me feel like I was watching a kid's show lol
My 08 ltz is a beast in the snow.
Nice test
I have a 2011 Ram 1500 Big Horn and prefer the auto 4WD because I can get up inclines when stopped at a stop sign. In 4 high both tires tend to slip and I get nowhere. I don't have the standard axles, not the limited slip or posi. Interesting subject as I think a lot of people are battling more snow this year than the previous three or four years. I would love to see you do this again in a pickup, especially a new Ram.
That is one of the reasons I bought a Silverado--got to love that auto-locking rear axle.
Keep the suburban videos coming! Ike gauntlet please !!!
F-150 KING OF TRUCKS how eo you know? dont answer me because is a chevy
King of king ❤❤❤❤❤ I love the truck
can you guys do a real awd vs 4wd comparison? You have the perfect opportunity in the Tahoe vs Escalade or Suburban vs Escalade ESV. Same platforms, similar drivetrains, similar all season tires, different drive system and computer calibration.
I want this for snowkiting trips
Andre is SUCH a good actor!! Hahahaha I meant to mention in the last one seriously😂😂😂
The Suburban with better weight balance is awesome in snow. My year 2000 model has 4-Low.
it is definitely crazy out. I live on long island and theres about a 3 ft tall snow drift on my driveway right now and its not even close to over. Crazy storm is everywhere.
That one or two days in the winter when we get to play like this make owning a tahoe/suburban worth it year round
Beautiful.Greetings from Fiji. Wish we have snow to test e'm beast.
can you guys get the new z71 tahoe add see how it does off road? it looks like they removed the front chin and gave it better off road tires so can you guys do it
+2017 zl1 camaro/2017 camaro fan We will try.
The Fast Lane Truck ok
My AWD Ridgeline and AWD Acura TL, BOTH WITH SNOW TIRES, get me through the Canadian ice and snow with ease....real SNOW tires are a must if you are serious about getting around in winter conditions.
cool video and lovy chevy
Boy that sure does look like a nice truck suv whatever u want to call them. My brother used to have a 1987 suburban with the 350 motor and 4 speed auto. Was very fun in the snow for sure. But me I will just keep my good old f250 4+4 obs
I was blown away by the gas mileage. I bought my new 2017 LT home with 78 miles on the odometer. Then my wife and I went on a shakedown cruise up and down a steep mountain grade, some city driving, and some highway cruising. 150 mile trip total. Door to door fuel mileage was 21.0, and that is on an engine with almost no break-in miles. And we're talking about a 3-ton vehicle. Amazing!
Andre is Funny, I like his Russian snow hat. I want one. That being said. Suburban is cool but only problem is you can't get the new ones with a diesel and a stripped down version with out the power windows, power door locks, cruise and A/C and you can't get Barn doors in the rear. I remember when you could get a plain jane Suburban with out all the power features and when a rear seat was an option.
I loved the suburban 👌
Same tires on my Navigator. I haven't used them in the winter. I didn't think they'd do this well.
nice video
The big boy handled it pretty well, when he wasn't relying on only two of his wheels!
Would be interesting to put on a set of high end snow tires and do the same test.
Pretty sure All Seasons are not winter tires.
great video, thank you. use winter tires in winter next time.
I noticed that the 4wd knob did not have a 4-Low selection. What's going on there?
+Michael Miller Yes, different 4x4 system in the Suburban.
The Fast Lane Truck is it possible to get a suburban or a Tahoe with 4-low anymore?
I believe thats a z71 option.
Michael Miller 4-Low available with Heavy duty trailering package. Got it in my suburban.
I am pretty sure that means there is no 4-low for this vehicle. But, I could be wrong.
That was awesome! :) :)
Just bought one of these. Except I got the LT with no options. It's amazing what the mid trim level comes with as standard. Everything I want and nothing I didn't need. It's perfect. And it was 20 grand less than this one they tested here. A bargain!
Nice video guys. Tommy looks a lot like Roman. 😊
I would love to see you guys compare 4WD and 4WD with locking differential in the snow.
Well some suberbans yukons have a rear locker built in and most people don't even know
Hey TFL - do you think you could do a snow and ice comparison test between all season tires, all terrain tires (BFG KO2's, Duratracs or similar) and dedicated winter tires (Nokian LT2 maybe for trucks?). Would be cool to see how they perform on say a figure of eight course and some braking and accelleration tests on snow :)
Driving in snow I only use 4hi in my Silverado, I put it in auto when I come to an intersection where I am turning. Using auto all the time wears out to 4wd system because it's constantly shifting in and out.
Those tires look lethal for that kind of weather :S Getting going is one thing, but stopping again is another matter! Would have thought that people living in areas that get regular snow had a set of proper snow tires for winter use?
Most manufactures put tires on that are just good enough to get you off the lot when you buy the vehicle. Those Conti's are actually a step up.
Same here in Norway, but we only run the OEM tires for summer use, and buy a second set of rims and tires for winter use :) The difference between all season tires, or even mud+snow rated off road tires, and proper winter tires is much larger than most people think.
Edit: I run Nokian Hakka 8 studded tires on my truck, and Hakka 7's on my girlfriends Miata. Studded tires are another huge leap above even proper friction tires, but of course they aren't legal everywhere. Had Nokian Hakka R SUV's on my previous truck, those were pretty good but for a heavy vehicle there really is no substitute for studded tires :)
Viking84 I have those same tires on my Toyota Highlander with the 4cyl and 4wd. They are all season and are very good on the road when it's not snowing. Plus i never get stuck with them in the snow, btw I live in Massachusetts
I'm guessing some of the difference depends on how often you have to drive on snow. Where I live we have ice and snow on the roads for 3 to 4 months of the year. We therefore drive the same distances (and speeds for the most part) in all conditions - so it's not about getting stuck, but about being able to safely do 50mph on snow covered back roads every day of the year :)
If you only get snow once or twice a year you can just drive slowly (or not at all) that day and you will be fine ;) After the first snow fall this year I tested my truck on the tires I use during summer, M+S rated General Grabber AT2's. They are snow flake rated, but they were completely useless on anything but fresh deep snow. Ice was down right dangerous. I didn't get stuck, but I couldn't do more than 20 mph without needing a loooooooong time to stop again, not to mention the poor handling in corners.
The key to using one set of tires is looking at snow flake rated tires ONLY. And even those are dangerous sometimes.
I currently run BFG Urban Terrain T/A, which is a new snow flake rated light-AT tire and they are absolutely fantastic. I have direct comparison with winter tires and these BFGs are only marginally worse, if at all.
The all-weather industry has progressed a lot, there is no denial. Take a look at tire test from Germany, for example (AutoBild magazine). Some of the all-weathr tires are unbelievably good.
4 wheel lock (high) isn't as safe as all-wheel-drive (not locked) for driving except for when you are in deep snow at low speeds, are stuck, or off-road. Locking the axles together is less stable but offers more grip when you really need it.
I got well and truly stuck in snow on Utah Rt-12 in a Mercury Mountaineer rental with AWD and no 4x4 option. It was admittedly older and the computer power transfer was far less sophisticated. I'm with Andre. I'd use 4x4 high.
More suburban please!!!!!
Put some sand bag in the back to weight it down it help my rav4 awd from sliding my 03 Tundra limited love the snow never got stuck on me once I use 4hi didn’t even have to use 4low in a foot of snow was sliding a little but keep on moving
Tommy! Can you do a video testing the rubicon tires on the snow?
So many people who cannot afford these are compliant but here’s a fun fact Chevrolet sells more fully loaded LTZ suburban than any other trim so obviously it’s a appropriate price. I see tons of them picking up kids everyday people have the money and want to spend it on something big.
guys you should use winter tires really
please make more videos like this
what kind of transfer case does suburban use? clutch type or the traditional gear type?
wondering how fast will the "auto" switch between 2wd and 4wd, and if it will work when the speed is more than 60mph?
school has a snow day... said NO one in Texas ever!
seriously! that seems to be a raw deal to me... maybe... oh wait not maybe... I know you're tougher in Montana that they are in Cali.... ;-)
Jackal's Outdoor Channel we get snow here. usually only a couple of days, other two weeks are ice.
Thankfully only a day of snow this season
Jackal's Outdoor Channel, actually we get more snow days than you would think. Due to the fact that no one down here preps their vehicles for the cold months, if any sleet or snow hits the ground they cancel school. Happens every few years.
Jackal's Outdoor Channel obviously, you’ve never lived in the Texas panhandle!
Jackal's Outdoor Channel ii
What about the full time AWD in the yukon denali's with no selector switch at all ? I would like to see a test of that system.
Currently shopping for snow worthy a vehicle to replace my Jeep Grand Cherokee. I live in rural northern Illinois and the plows can’t keep up. Considering a Tahoe, so this is close. 😁
I wish they still made a 3/4 ton suburban with the 8.1
you can get the suburban with a 6.0 vortech in l or m vin code, but you have to buy through fleet services at the dealer. the government does buy these with duramax option. you can also buy the 3500 van with a duramax, but no alison, ive seen them at the gov fleet resale dealer in sacramento cal. the suburban is more of a hybrid 2500-3500.
I'm confused,you can get a 40k Silverado with the 5.3 and an 8 speed transmission but you only get a 6 speed in a 70k Suburban? That doesn't really add up for me.
RaceARoni Im guessing because the Silverado customers are mainly using it to tow stuff while suburban customers are towing people. To be honest Im with you, 30k extra and it should have a 6.6L in it!
either you can afford or you can’t . there’s no for excuses .
That's sticker . Da hell u wanna pay sticker
Having tried 4x4 high and 4x4 low over at Tahoe I can say that driving a z71 silverado is awesome. Please don't even compare to small car's AWD;) I like them too though:)
Tommy, you misspoke at the end. That secret compartment is not in the Silverado, but in the Suburban that you were sitting in.
Tommy and Andre make a great team
U know that automatically engaging 4x4 can be nice but I have seen transfer cases that have exploded because of it so I prefer to just engage it when I think I may need it
This is just speculation, but I'm guessing the transition was so seamless in 4wd auto because the computer likely was already in 4wd from the start. A lot of systems will engage the 4wd at launch regardless of slippage.
As the truck ages 4 auto starts to become a little rough so I don’t use it anymore. I can hear stuff clunking every time it engages lol
I prefer to have snow tires on 4x4 or AWD vehicles on snow or icy roads. Mine have snow tires on and have no problem getting up the hill or icy roads or even bring it to stop in the short distance compare to all season tires. Getting to stop the vehicle is the main key on snow or icy roads vs how fast it goes from stop on snow or icy roads.
The cubby is a good place to put an ipod or large jump drive (128 or 256 gb) . That stereo will play Wav files, too.3
The Fast Lane Truck You should have snow tires instead of those all season tires on it I have had 4WD Suburbans through 3ft snow drifts.
Why on Earth are suburbans so expensive?? Aren't they basically a sliverado with extra seats and a camper shell?
Because people are stupid enough to keep paying the higher prices so automakers keep throwing higher prices on vehicles year after year. If people plain stopped buying they'd stop with the ridiculous price gouging.
William Todd, sad but totally agree.
No they are much more then a Silverado with a shell. Different frame and underpinnings, different suspension, far different interiors. Yes they are expensive, but much different from the trucks.
@@phillcolborne p
@@phillcolborne You are wrong about the frames being different. I agree with the other points.
I would like to see what the difference would be in acceleration if you change your car tires to Nokia Hakkapeliitta series tires
I'm surprised no one found WALDO!
He's right there with Andre.
Can you get a z71 and test it off road?
Fun video, makes boring facts fun
3 degrees? That's sad. We had -42. And we didn't have school. But Star valley Wyoming did. And they had -54.
I'd say again, tires are everything.
