GMC Sierra and Chevrolet Silverado are the same vehicle, they are manufactured in the same factory and use the same parts under the engine, putting them in a test together is basically putting two of the same truck in a test
uh.... when my locking diff locks in my chevy, that makes both rear wheels turn the same speed. should have no issue going up the hill, not sure how they screwed that one up.
***** Probably because they had all seasons on the rest of the trucks besides the tundra and the f-150. Shoulda ran the same type of tires on all of them. I drive a 2wd silverado w/ nitto highway terrain tires (lol) and I get around just fine in the snow and ice.
Connor Harrell the Ford and the gm were running the same Bridgestones. Unfortunately it is the locker in the gm itself that is the issue with this test. With the g80 it locks the rear end at 50/50, whereas with a limited slip the traction control can apply the brake to the wheel that is slipping forcing the power to go to wheel on dry pavement thus moving the Ford and Toyota to the top. That and those trucks weigh more and that also helps with the test.
Vanilla Bleach my good friend the test they are trying out here is not a true test of traction control in a real world situation.., these are all 4x4 trucks they are testing and this is clearly a 4x4 situation, so you simply hook 4x4.... when you learn to drive maybe then you can come back and we can continue this lovely civilised conversation on the difference between 2WD and 4WD... have a great day...
in lots of situations its better to not use 4WD until you need it, because if you get stuck in 4WD; your fucked meanwhile if you get stuck in 2WD you still have 4WD to bail you out.
The guys that performed this test don't know how to drive, or to use the vehicles the way they are designed. The GM trucks did not have a traction control system, just automatic locking rear ends. But they tried to drive the GM trucks like they had traction control. Traction control cuts engine power to stop wheel spin. In the GM trucks if the they had simply let off the gas a little after the wheel spin began, the trucks would have walked up the hill with ZERO problem. The fact is they didn't operate the vehicles the way their respective systems were designed to be used. If the truck doesn't have a traction control system to cut engine power, guess what? You have to do that with your own foot. They just mashed the gas pedal in each truck, they didn't use the proper tools, it would be like if a carpenter tried to build a house using only a hammer, no saw, no measuring tape, no level.. gee how would that house turn out?
+Chris Winings Good comment i totally agree' GM been using the G80 locker for a long time, if they would have let up the throttle while the locker is engaged the trucks would have no problem.
+Keith Bartlett Yeah at one point in the video you see the driver just lets off the gas as soon as the tire breaks loose, not even enough time to let the g80 lock. My g80 has saved me so many times.
Frater Mus Yes, I have a G80 in my S10. For the G80 to work it must go like this. > Rear tire spins in low traction conditions > Ease off throttle, at the same time the automatic locking differential engages > Now the tire with most traction has torque, so you crawl out In this video they were just fucking putting the throttle to the floor, as you can see in the video, the wheel that was on the High Traction suface was burning out because the dumbasses were just trying to gun it up the hill. you're supposed to let the locker engage and then crawl up the hill. How can the tire gain any traction if they are purposely spinning it?
thanks , now it makes sense. I'm curious to know also, why the bed is not soldered as a single piece to the cab. Torsional rigidity would surely get better. P.s. here these kind of vehicles are not on sale , except for some toyota hilux
For this particular test it really doesn't have a huge effect. What mostly matters is one tire has a lot more grip than the other and that's what this test surface layout does. It isolates the function of the traction systems, not the amount of traction.
atta shmeebs You and AIW BEC clearly missed the point and how this whole thing works. Tires makes zero difference in the test they are doing. Only 1 wheel was breaking loose, not both. If both back wheels had broke loose then yes, tires would make a difference but they didn't.
Gm offers the G80 rear differential for both the Silverado and the Sierra. I don't understand why they wouldn't use the G80 in this test. It would put all those trucks to shame.
KevinFish556 Not really. It's called the idiots Making the video don't know how a fucking mechanical locking rear diff works. If they habe feathered the throttle for a second, the locker would have let them creep right up the thing no problem. Chevy GMC and Nissan had different forms of lockers. The hosts didn't know how to use either. That's not the trucks fault. Lift one of those rear tires of the Ford off the ground eben an inch, and it's not moving at all. The trucks with lockers wouldn't have this problem. The locker doesn't engage when you floor the throttle like a dipshit, because that rear end would hook up so fast you'd either give yourself whiplash, or watch the rear axle going up hill without you. Also, if locking diffs are so "bad" as these guys claim... Then why does every serious off road vehicle, from hummers, to land rovers, to big Russian military 8x8s have them? Look it up if you don't believe me, because I AM right.
blackhawks youre absolutely right. they didnt know how to use the locker. If you look at gm when they test the gmc trucks with lockers, they allow the automatic diff lock to engage, pull back the throttle , then creep up the hill. This is an important point because even the car makers recognize the importance of pulling back throttle. in the video they say the computer pulls back the throttle in traction control..., but when driving the lockers they dont pull back the throttle. pull ing back the throttle should be done by the driver when driving a g80 locking diff in most situations with only 2wd engaged.
You need to get glasses man.. Ford never hit the pavement. Oh and INB4 hate, I do not own any kind of Pickups or Ford Cars, I just randomly clicked this video.
@296jayce you're right but lockers are only better in extreme off road situations you can't keep them engaged all the time and absolutely not to be used on road , but limited slip is for everyday driving.
I had a 2007 f150 and it broke down a lot so i got a Silverado, but to my surprise it was even worse. Everything fell apart in only one year. This year I ended up getting a Toyota and so far it is still doing good.
I have no button, but a long maneuver to do so, but what's the point of it if I am going to turn it off? note also that in Prius when turning traction control off you lose ESP (stability control) too...
A lot of confusion here. First, there was confusion over what this test was for. It was not for which truck had the best 4WD. It was for which truck is the most capable in 2WD on a split mu surface. But what this test showed is not really which truck had the best limited slip or traction control. No, it was really which truck had a COMBINATION of the best limited slip or traction control AND most weight over the rear axle. As you can plainly see in the GM trucks, BOTH rear tires are spinning. You can have all the locking differentials and traction control you want. The tire WITH traction was spinning and that was not enough to move the truck up the hill. This test did not prove what they set out to prove. But the result actually is somewhat useful: it means the F-150, exactly as configured, would have the most capability up a hill in 2WD. In the real world, however, you'd already be in 4WD, so this is just kinda lame.
+kevin9c1 Yes, Kevin, exactly correct. They only used 4WD as a last resort. Maybe, to keep many of the naysayers and ignorant people at bay, they just should have used 2WD trucks to begin with.
+kevin9c1 With BOTH rear tires spinning, PROVES to me that the test was biased. The right/passenger side WOULD have moved the truck B/C it had traction. the limited slip is JUST THAT. The video was rigged plain and simple
+Tyann Huffman I don't know about biased in the human sense. But biased in the scientific sense, definitely. But your explanation is not right. You are saying if the right rear tire had traction, it would have moved the truck. Not true. Traction is not absolute, even though you may think of it that way. So, yes, that one tire did have the MOST traction (the other one basically had none). But that tire still did not have enough to push that truck up that grade. At that point, it's either a tire test or a comparison of how much weight is over the rear axle (the F150 probably had more). My point was, this really wasn't a traction control/limited slip test, at least not when the GM trucks are spinning the tire WITH traction.
Mike Levine was the main editor for PickupTrucks.com when this test was performed and is the voice you hear in this video. He was well known for joining in the childish comments on PUT.com and defending his position even when he was clearly in the wrong or clearly caught in the wrong. Oh and by 2011 he left PUT.com to become the head PR guy at Ford. When they tested the Sierra and Silverado, he didn't even attempt to ease into the throttle and let the tires grab. If you goose the throttle like they did here, you'll never get the truck to hook up in 2WD, even when the rear diff is locked.
hochhaul no shit. the chevy and sierra were the only ones transferring power hard to the other tire on the pavement, proving it could get out in 2 wheel drive with the locker...but still that is only 1 tire trying to push the whole truck up a steep grade....can't floorboard it like the others or it will break loose......the others struggled to get power to the tire on the pavement.....they've done exact same test like this with chevys before and it blew the competition away (and all of these in the video) but you gotta know how to drive it.....
Rexford L Limited slips have clutches so when extreme pressures are present it can slip slightly but more likely to wear out where mechanical differentials will never wear out but they are more likely to break because they do not have the slipping feature. I like both, but lockers are better. Remember, something always has to give, But believe me they can break, I exploded both systems before
This test doesn΄t represent real conditions as they say. On icy road and snow you engage the 4WD before you lose traction, not during the loss or after and you don΄t push the throttle to the redline. Nissan prefered rear WD open differential with electronic lock for less weight and higher top speed. When the driver engaged the 4WD, the diff locked and the car left without any problem. The offroad obstacle course represents real conditions and makes obvious which truck has the best 4WD.
I don't think ANY truck should EVER have an open diff! EVER!!! Most USELESS piece of shit differential, especially when you need traction the most! 1 wheel peel burnouts & getting stuck on rain wet hills, let alone snowy or icy! Just keeps spinning the wheel with the least amount of traction! Completely OPPOSITE what you need!!! The ONLY benefit to open diffs is they're cheaper and typically last longer due to taking the path of least resistance with torque (AKA the most slipping wheel)... But the other things you said... Lighter? Hardly! Couple of lbs, tops, not that they're concerned with that in trucks anyways. Higher top speed?! What are you smoking? A differential is just a way to divvy up torque based on given traction situations. An open would be no more faster than an LSD or locker. Also, again, it's a truck, & not even like an SRT Ram or an F150 Lightning, so top speed isn't even a factor. What did you have to eat to pull those "facts" out of your ass? Not trying to be rude, but seriously, that's a huge bunch of bull.
JoeIsCrazyWillman First of all, many people don't have the ability to discuss like a civilized person. Obviously, you have this disability... At first, what I said, were told to me by a BMW engineer and spare parts dealer. He owns an E46, so I think that he knows better than anyone the top speed of his car before and after changing diff. In theory, it should be the same, but the best way to determine it is by test driving the car. Some pick up drivers need the higher top speed, as they try to arrive as fast as possible to their destination, when they don't have cargo. I have nothing to prove to anybody, I know what happens... Secondly, the LSD diff has some extra components. Obviously, they have some weight. This weight might be negligible for a car to carry (it's not), but significant for a transmission to rotate. Simple test: Lift a car and a bike off the ground and find which ones wheel spins a lot easier. The more weight that is added, the more effort it needs to rotate it, meaning higher consumption... Finally, I will repeat what I said: Regardless if your car has an open or a LS diff, you will engage the AWD in slippery conditions. No burnouts,no spinning wheels... Take your time, study how the diffs work and what the extra components are. You need a lot more effort and progress to teach engineers their job, criticise people about their opinion, what they smoke and what they dump out of their asses...
I agree with the manual trans comment, however the Frontier is not in the same class. They should have a test between ALL of the smaller pickups though.
Except this test was shit. The idea behind traction is to finesse the throttle, not gun it until you get to the top. Mike Levine (now the head of PR at Ford) gunned it instead of backing off the throttle and letting the locked diff do the work. A locked diff in 2WD doesn't do any good if you roast the tires right off the bat. And an overly aggressive traction control is a pain in the ass in the winter.
Limited slip is no different than an open diff it makes no difference, I bet a lock right would make a difference, it locks up both back wheels for full posi.
Skeefoo Panama that can't be more fucking wrong. Limited slip sends power to the wheel with the MOST amount of traction unlike a open diff which sends power to the wheel with the LEAST amount of traction, a lsd will usually send power back and forth to get you to keep moving, while an open diff will just continue to spin the slipping wheel until it redlines
+mikebing1230 OK Bing, You need to see the Power Trax no slip locker video on here, Limited slip is not positive traction, it is hardly any better than an open diff, only 1 wheel spins with Limited slip. Limited Slip IS NOT positive traction.
Because Limited Slip is almost no better than an open diff, as far as your ass getting stuck, It may make a slight difference, it may transfer power to both wheels, on and off, but a LSD is NOT posi traction, and WILL get you stuck. It's only slightly better than open diff, Still you will need a locker for a real rear posi trac axle.
@Tungsten23 It's based on a difference in RPM between the two tires. At 100RPM difference the flyweights on the cam open and the paw grabs the engagement mechanism. It can engage in forward or reverse, but not past 20mph. The clunk that is heard is the paw engaging on the mechanism.
Wow, Just wow. Trucks like these are very necessary for hauling loads, and normal people that aren't "hillbillies" drive them. If we didn't have these trucks, we wouldn't be able to complete many jobs and tow/haul heavy loads.
The traction control in my 2011 F150 is amazing. With the stock goodyear SRA, same as in this video, driving on snow and ice feels like I'm driving on dry pavement. No slipping or sliding at all which is suprising since these tires are complete garbage.I don't even need to use 4x4 unless going uphill.
Right, understood. I live in Colorado so driving in snow is not new. From my experience though when you hit ice 4wd or 2wd your going to slide a bit no matter what. About the 4wd system going off at high rate of speed I just wish more people new that. Many drivers think they can go fast in 4wd then they spin out at a turn.
Day after a day, starting from the Land Cruiser, though Fortuner, passing by Camry and Prius then Tundra, etc... I discover that Toyota (vs other car manufacturers) may be not the funniest to drive, neither the most fuel efficient nor the most powerful, lastly not nearly as comfortable, but it has one strong point, Reliability and Capabilities, they are well but not over engineered. Cheers for Toyota, Thumbs up for Lexus for dominating both worlds.
the issue with the import pickup manufacturers, their highest capacity pickups are only 1/2 ton.. you can get heavy duty class 3 and even class 4 pickups from the big 3..
Most pick-ups are part-time or selectable 4wd, meaning that on top of 4wd high and 4wd Low, they also come with a 2wd setting and sometimes even an AWD setting. however, on the truck without an awd setting, it is strongly recommend that drive in 2wd in which driving on road to prevent excessive wear.
@PsychoDemon5 it doesnt matter...it depends on what the companies offer. they are testing what the vehicles come with. if you put the ford's locking system in every truck and the same tires on all of them, most likely they will all get up with little difficulty. they are testing the actual trucks and what they do the way they come.
did they think about taking the Type,Brand, and performance level of tire on the truck into effect? if they put the same type,brand, and performance level tire on each of the trucks im sure the outcome would have been different.
...And the same types of differentials. The point of this test, though, is to show what the manufacturers offer given certain trim levels, even though it would be nice to know the exact specs of each truck.
so did the rear diff's fail to lock on both the gm vechicles causing them to use 4wd, or did the rears engage and they still had to use 4wd? it sure looks like testers were trying keep them from locking in the suspiciously limited video of the gm vehicles. i have a hard time believing that a truck with a locked rear end couldn't make it up the hill in 2wd. makes me question this whole shoot out.
I'm not positive, but I think it's so that with heavy loads the bed can flex slightly without effecting the rest of the body. I have heard that some of the ford unibody trucks made in the early 60's had problems when hauling heavy loads. The door gaps would flex so much that the doors would pop open while driving. That is probably why today's unibodies are usually meant for pretty light hauling.
what also makes a big difference is the type of tires and the type of LSD that is utilized. try a truetrac in the chevy instead of the gov lock and see what happens.
I find it only safe to assume If it's a test of the preformance of the STOCK truck the way it come's when you pick it up, Then No their should not be the same tire placed on the truck. This video is pointed to a dealer ship pick up turn key and go.
i can't post the link. so search: Mega Test Dodge Ram vs. Ford 350 vs. GM. first thing in the test shows how a 2wd with a locked rear end can get up a slick surface better than a 4wd with open diffs
Agreed i drive 94 ford F150 and i live in the Minnesota. In snow I cant make it through the trail my dads Chevy makes in 2wd with his Chevy which has locking differential when im in 4wd. my truck has open rear and limited slip front.
@FreeSkier155 Well you are right, but if you are going up a hill during winter and there are cars behind, the last thing you want to do is have to stop and pop the truck in 4x4 to make it up a hill. It could cause an accident from your truck sliding backwards if you stop too quickly from panic or begin to slip back before you can get it in 4x4. This test shows which truck would be most reliable in this scenario, which is just one of many.
Was it the same driver for each vehicle? I have seen many many occasions where switching to a driver that knows how to maneuver these situation makes a truck that looks useless go to gold
The Titan would have cam first if it's e -locker was engaged, and the silverado did the second best as you can clearly see the tire on the ashfault spinning (it just wasn't as heavy)
If you look closely, the GMC and the chevys tires lock up almost immediately. Because there is equal power going to both tires on different surfaces, the rear end starts to go sideways. This is why a lot of drifters use an E-locker or a stout LSD. An LSD just makes more sense for this kind of test. It distributes the power accordingly to how much grip each tire has rather than just locking them at the same speed. The outcome may have been different if both tires were on the slick surface.
If you live in conditions for a 4X4 you are not going to drive in the snow or iced roads in 2 wheel drive. I understand testing the Traction Control but that is why they have 4 wheel drive so the Traction Control doesn't have to work so hard. Maybe if they re did the test where you drive through a wet patch requiring Traction Control to activate. Or does anyone have an explanation for this type of test?
At 2:21 you can see the Chevy truck's rear wheel on asphalt. It's spinning like crazy, so the wheel with traction is getting plenty of power. It's just that that one tire could not get the truck up the hill. Seems to me more like a tire or weight problem, than a traction control problem.
my 1996 k2500 suburban with a g80 would walk right up that. how is a limited slip better than complete 50/50 power. ive used limited slip before and found that it takes a lot of wheel spin where my g80 takes a little and once locked stays that way until i completely let off the accelerator.
@finonm7 same here i have a 2009 f150 and it does have a traction off button button it still engages when i spin the tires just delayed a bit longer which sucks ass
Sierra is made by GMC, (General Motors Corporation), which is in great partnership with Chevrolet, therefore they make very similar models of 2 different makes. Almost like Ford and Mazda, but yes. They particularly the same trucks, just some different exterior features.
I would think the gmc/chevy with the locking diff would do as well as the TC on the tundra and ford no? as soon as they hit the slip RPM the locker would engage and the tire on the pavement would propel the vehicle to the top.
My 2017 Sierra Denali pickup slides out of control in 4WD in any type of snowy conditions and doesn't handle much better in the rain. I just saw I have traction control and now I am not sure if it was off or on. Now it's summer and I can't try it out both ways. However, it almost killed me spinning out of control. GMC service can't duplicate the problem and says it appear to be working OK. GMC customer service sucks. Thoughts or suggestions? This truck is going to kill me, someone else, or all of us.
That's only with a helical diff, with a mechanical or viscous LSD the wheel with traction will always get some power, even if the other wheel is off the ground. The other way to get around this with a helical diff is to gently apply the brakes, this keeps some strain in the wheel off the ground and allows power to be transferred to the wheel with grip.
GMC Sierra and Chevrolet Silverado are the same vehicle, they are manufactured in the same factory and use the same parts under the engine, putting them in a test together is basically putting two of the same truck in a test
Aric Castro is true is the same truck
just body works and prices
Yeah and neither one of em could make it lol
Aric Castro they are the same but yet some people will still say they are different
They just change the logos
@@splitrim509 because the test was rigged. Take that to the bank.
I remember watching this when I was a little kid
SAMEEEEEEEEEEEEEE
uh.... when my locking diff locks in my chevy, that makes both rear wheels turn the same speed. should have no issue going up the hill, not sure how they screwed that one up.
Exactly my thoughts. My Tahoe does extremely well with the G80 and about 10k worth of weight.
***** Probably because they had all seasons on the rest of the trucks besides the tundra and the f-150. Shoulda ran the same type of tires on all of them. I drive a 2wd silverado w/ nitto highway terrain tires (lol) and I get around just fine in the snow and ice.

a locked diff is a locked diff, the wheels should be turning at the same speed.
Exactly
Why would you have 4 wheel drive and not use it under these conditions?
EXACTLY.., what the heck good is this test..?? if you buy a 4x4 you use the 4x4..!! well at least I do...
hootizzz it's testing traction control dumbass not how well the 4x4 works
ubb4me Because like the video explains in the very beginning, most trucks have rwd.
Vanilla Bleach my good friend the test they are trying out here is not a true test of traction control in a real world situation.., these are all 4x4 trucks they are testing and this is clearly a 4x4 situation, so you simply hook 4x4.... when you learn to drive maybe then you can come back and we can continue this lovely civilised conversation on the difference between 2WD and 4WD... have a great day...

also in the states, most of your trucks are autos, use manuals much better :)
Is the proper operation of the G80 is to first let it spin to lock up, then proceed at lower throttle?
Frater Mus Yes, I have a G80 in my S10. For the G80 to work it must go like this.
> Rear tire spins in low traction conditions
> Ease off throttle, at the same time the automatic locking differential engages
> Now the tire with most traction has torque, so you crawl out
In this video they were just fucking putting the throttle to the floor, as you can see in the video, the wheel that was on the High Traction suface was burning out because the dumbasses were just trying to gun it up the hill. you're supposed to let the locker engage and then crawl up the hill. How can the tire gain any traction if they are purposely spinning it?
but why test a Silverado AND a sierra.....
Nissan just stop trying lmao.
the titans aren't bad i got a 2013 and it a amazing truck had no problems with it unlike the chevy and dodge we had
***** they have been doing horrible on tests
i like mine best truck i had yet and its mint in the snow
give it a year or 2 and it will be a rust bucket like every vehicle in the snow
o well it rusts then it rusts every vehicle does
I miss the old days.
thanks , now it makes sense. I'm curious to know also, why the bed is not soldered as a single piece to the cab.
Torsional rigidity would surely get better.
P.s. here these kind of vehicles are not on sale , except for some toyota hilux
this really comes down to what tyres each truck has on
Which is totally the manufacturer's choice.
I was thinking the same thing... I believe tires make a hell of a difference. Funny when people go offroading with bald or hwy tires.
For this particular test it really doesn't have a huge effect. What mostly matters is one tire has a lot more grip than the other and that's what this test surface layout does. It isolates the function of the traction systems, not the amount of traction.
the only way for this test to be fair would be for all of the trucks to have the exact same tires.
atta shmeebs You and AIW BEC clearly missed the point and how this whole thing works. Tires makes zero difference in the test they are doing. Only 1 wheel was breaking loose, not both. If both back wheels had broke loose then yes, tires would make a difference but they didn't.
Why test both GMC & Chevy trucks? Their both the same.
Gm offers the G80 rear differential for both the Silverado and the Sierra. I don't understand why they wouldn't use the G80 in this test. It would put all those trucks to shame.
I am not picking one brand over another, but seems more like a tire test than a truck test.
You guys must update this test with new trucks from 2016
2017 Ford Raptor
i don't even get this shit, if i'm driving any of these trucks in snow and ice i'll have it in 4 high
stupid test
But what if your transfer case blows out hm? What will you do then
So Ford beat GMC at their own testing facility... nice
Gm. **
KevinFish556 Not really. It's called the idiots Making the video don't know how a fucking mechanical locking rear diff works.

I don't get it, the ford had half of its tire on the pavement, where the rest had the full tire on the tiles. Hardly seems like a fair test...
when exactly did this happen?
watch the video ethan. Ford #1
+Focus On the Focus I watched it. never did it touch the pavement
oh ya nvm. Ford #1
You need to get glasses man.. Ford never hit the pavement.
Oh and INB4 hate, I do not own any kind of Pickups or Ford Cars, I just randomly clicked this video.

I had a 2007 f150 and it broke down a lot so i got a Silverado, but to my surprise it was even worse. Everything fell apart in only one year. This year I ended up getting a Toyota and so far it is still doing good.
i hate traction control. its aways hurt me more than its helped
Especially in my Prius, hell engages even when I floor it on a dry asphalt surface...
Tareq Arar on some Toyota models there's a button to turn it off.
Tareq Arar almost all*
Most vehicles are that way
I have no button, but a long maneuver to do so, but what's the point of it if I am going to turn it off?
note also that in Prius when turning traction control off you lose ESP (stability control) too...
A lot of confusion here. First, there was confusion over what this test was for. It was not for which truck had the best 4WD. It was for which truck is the most capable in 2WD on a split mu surface. But what this test showed is not really which truck had the best limited slip or traction control. No, it was really which truck had a COMBINATION of the best limited slip or traction control AND most weight over the rear axle. As you can plainly see in the GM trucks, BOTH rear tires are spinning. You can have all the locking differentials and traction control you want. The tire WITH traction was spinning and that was not enough to move the truck up the hill. This test did not prove what they set out to prove. But the result actually is somewhat useful: it means the F-150, exactly as configured, would have the most capability up a hill in 2WD. In the real world, however, you'd already be in 4WD, so this is just kinda lame.
+kevin9c1 Yes, Kevin, exactly correct. They only used 4WD as a last resort. Maybe, to keep many of the naysayers and ignorant people at bay, they just should have used 2WD trucks to begin with.
+kevin9c1 With BOTH rear tires spinning, PROVES to me that the test was biased. The right/passenger side WOULD have moved the truck B/C it had traction. the limited slip is JUST THAT. The video was rigged plain and simple
+Tyann Huffman I don't know about biased in the human sense. But biased in the scientific sense, definitely. But your explanation is not right. You are saying if the right rear tire had traction, it would have moved the truck. Not true. Traction is not absolute, even though you may think of it that way. So, yes, that one tire did have the MOST traction (the other one basically had none). But that tire still did not have enough to push that truck up that grade. At that point, it's either a tire test or a comparison of how much weight is over the rear axle (the F150 probably had more). My point was, this really wasn't a traction control/limited slip test, at least not when the GM trucks are spinning the tire WITH traction.
Ya it was totally biased, it was even located at the GM proving grounds hahaha.
Mike Levine was the main editor for PickupTrucks.com when this test was performed and is the voice you hear in this video. He was well known for joining in the childish comments on PUT.com and defending his position even when he was clearly in the wrong or clearly caught in the wrong. Oh and by 2011 he left PUT.com to become the head PR guy at Ford.
When they tested the Sierra and Silverado, he didn't even attempt to ease into the throttle and let the tires grab. If you goose the throttle like they did here, you'll never get the truck to hook up in 2WD, even when the rear diff is locked.
hochhaul no shit. the chevy and sierra were the only ones transferring power hard to the other tire on the pavement, proving it could get out in 2 wheel drive with the locker...but still that is only 1 tire trying to push the whole truck up a steep grade....can't floorboard it like the others or it will break loose......the others struggled to get power to the tire on the pavement.....they've done exact same test like this with chevys before and it blew the competition away (and all of these in the video) but you gotta know how to drive it.....
@Jimpank90 This is not testing off road ability, but how well the TCS works. If you switch to 4WD the Traction Control is not needed.
one thing to consider in this test is your tires each brand and tread design performs differently to.
how am i here?
wheres here
from what ive found fords limited slips are the most reliable.
the most reliable limited slip will be a Torsen type differential.. since it's just gears, there's nothing to wear out..
Rexford L Limited slips have clutches so when extreme pressures are present it can slip slightly but more likely to wear out where mechanical differentials will never wear out but they are more likely to break because they do not have the slipping feature. I like both, but lockers are better. Remember, something always has to give, But believe me they can break, I exploded both systems before
@@54ord, not all limited slip diff's use clutches. The (Eaton) Detroit Truetrac uses worm gears in place of clutches.
This test doesn΄t represent real conditions as they say. On icy road and snow you engage the 4WD before you lose traction, not during the loss or after and you don΄t push the throttle to the redline. Nissan prefered rear WD open differential with electronic lock for less weight and higher top speed. When the driver engaged the 4WD, the diff locked and the car left without any problem. The offroad obstacle course represents real conditions and makes obvious which truck has the best 4WD.
I don't think ANY truck should EVER have an open diff! EVER!!! Most USELESS piece of shit differential, especially when you need traction the most! 1 wheel peel burnouts & getting stuck on rain wet hills, let alone snowy or icy! Just keeps spinning the wheel with the least amount of traction! Completely OPPOSITE what you need!!! The ONLY benefit to open diffs is they're cheaper and typically last longer due to taking the path of least resistance with torque (AKA the most slipping wheel)... But the other things you said... Lighter? Hardly! Couple of lbs, tops, not that they're concerned with that in trucks anyways. Higher top speed?! What are you smoking? A differential is just a way to divvy up torque based on given traction situations. An open would be no more faster than an LSD or locker. Also, again, it's a truck, & not even like an SRT Ram or an F150 Lightning, so top speed isn't even a factor. What did you have to eat to pull those "facts" out of your ass? Not trying to be rude, but seriously, that's a huge bunch of bull.
JoeIsCrazyWillman First of all, many people don't have the ability to discuss like a civilized person. Obviously, you have this disability...
At first, what I said, were told to me by a BMW engineer and spare parts dealer. He owns an E46, so I think that he knows better than anyone the top speed of his car before and after changing diff. In theory, it should be the same, but the best way to determine it is by test driving the car. Some pick up drivers need the higher top speed, as they try to arrive as fast as possible to their destination, when they don't have cargo. I have nothing to prove to anybody, I know what happens...
Secondly, the LSD diff has some extra components. Obviously, they have some weight. This weight might be negligible for a car to carry (it's not), but significant for a transmission to rotate. Simple test: Lift a car and a bike off the ground and find which ones wheel spins a lot easier. The more weight that is added, the more effort it needs to rotate it, meaning higher consumption...
Finally, I will repeat what I said: Regardless if your car has an open or a LS diff, you will engage the AWD in slippery conditions. No burnouts,no spinning wheels...
Take your time, study how the diffs work and what the extra components are. You need a lot more effort and progress to teach engineers their job, criticise people about their opinion, what they smoke and what they dump out of their asses...
I agree with the manual trans comment, however the Frontier is not in the same class. They should have a test between ALL of the smaller pickups though.
Is it possible to re-test on the 2015 models
Haha my friend has a 2wd Nissan Titan! Sucks for him!
Graded a truck on "not having to engage 4WD" on a 4WD test.... great idea
its a traction control test not a 4x4 test
Except this test was shit. The idea behind traction is to finesse the throttle, not gun it until you get to the top. Mike Levine (now the head of PR at Ford) gunned it instead of backing off the throttle and letting the locked diff do the work. A locked diff in 2WD doesn't do any good if you roast the tires right off the bat. And an overly aggressive traction control is a pain in the ass in the winter.
for a bunch of truck with "limited slip diffs" how come they only were spinning one wheel???
Limited slip is no different than an open diff it makes no difference, I bet a lock right would make a difference, it locks up both back wheels for full posi.
Skeefoo Panama that can't be more fucking wrong. Limited slip sends power to the wheel with the MOST amount of traction unlike a open diff which sends power to the wheel with the LEAST amount of traction, a lsd will usually send power back and forth to get you to keep moving, while an open diff will just continue to spin the slipping wheel until it redlines
+mikebing1230
OK Bing, You need to see the Power Trax no slip locker video on here, Limited slip is not positive traction, it is hardly any better than an open diff, only 1 wheel spins with Limited slip. Limited Slip IS NOT positive traction.
Because Limited Slip is almost no better than an open diff, as far as your ass getting stuck, It may make a slight difference, it may transfer power to both wheels, on and off, but a LSD is NOT posi traction, and WILL get you stuck.
It's only slightly better than open diff,
Still you will need a locker for a real rear posi trac axle.
Skeefoo Panama never said limited slip is a locking diff, limited slip is positraction. But Posi isn't the same as a locker.
@Tungsten23 It's based on a difference in RPM between the two tires. At 100RPM difference the flyweights on the cam open and the paw grabs the engagement mechanism. It can engage in forward or reverse, but not past 20mph. The clunk that is heard is the paw engaging on the mechanism.
Did you think about tires? Seems like they used stock tires on each truck, could make a huge difference in the traction control tests....
There's sure a lot of butthurt in these comments. The fervor is almost religious.
+Dave Smith Amen to that. lol pun intended
+Dave Smith Oh my. The hurt.
Truck people are a different breed of car people.
"HIEEEEELBILLY! YEEEH-HA-HAW!"
The automobile for trump supporters
Wow, Just wow. Trucks like these are very necessary for hauling loads, and normal people that aren't "hillbillies" drive them. If we didn't have these trucks, we wouldn't be able to complete many jobs and tow/haul heavy loads.
Traction control at worth shit if you don't have good tires
The traction control in my 2011 F150 is amazing. With the stock goodyear SRA, same as in this video, driving on snow and ice feels like I'm driving on dry pavement. No slipping or sliding at all which is suprising since these tires are complete garbage.I don't even need to use 4x4 unless going uphill.
Right, understood. I live in Colorado so driving in snow is not new. From my experience though when you hit ice 4wd or 2wd your going to slide a bit no matter what. About the 4wd system going off at high rate of speed I just wish more people new that. Many drivers think they can go fast in 4wd then they spin out at a turn.
Day after a day, starting from the Land Cruiser, though Fortuner, passing by Camry and Prius then Tundra, etc... I discover that Toyota (vs other car manufacturers) may be not the funniest to drive, neither the most fuel efficient nor the most powerful, lastly not nearly as comfortable, but it has one strong point, Reliability and Capabilities, they are well but not over engineered. Cheers for Toyota, Thumbs up for Lexus for dominating both worlds.
the issue with the import pickup manufacturers, their highest capacity pickups are only 1/2 ton.. you can get heavy duty class 3 and even class 4 pickups from the big 3..
Why did I even give the Titan a chance. What a waste of time I spent test driving those pos. Very happy with my Tundra. Made in Texas by Texans

I had Ford 150. But Toyota Thundra is way better than Ford. I can clearly feel the difference.
Ali M Ford f150 is alternative to tundra, other than that Toyota all day every day.
The Nissan Pro-4x model there did have a locking diff... You just have to be in 4wd to engage it.
limited slip should do better because it would send power to the wheel with most traction right?
These comments are cancer
toyotaaaaa
This driver is shittier than me, and I'm 14
Most pick-ups are part-time or selectable 4wd, meaning that on top of 4wd high and 4wd Low, they also come with a 2wd setting and sometimes even an AWD setting. however, on the truck without an awd setting, it is strongly recommend that drive in 2wd in which driving on road to prevent excessive wear.
@PsychoDemon5 it doesnt matter...it depends on what the companies offer. they are testing what the vehicles come with. if you put the ford's locking system in every truck and the same tires on all of them, most likely they will all get up with little difficulty. they are testing the actual trucks and what they do the way they come.
did they think about taking the Type,Brand, and performance level of tire on the truck into effect? if they put the same type,brand, and performance level tire on each of the trucks im sure the outcome would have been different.
How about getting a Titan that actually has the VDC "vehicle dynamic control" for your unbiased test.
...And the same types of differentials. The point of this test, though, is to show what the manufacturers offer given certain trim levels, even though it would be nice to know the exact specs of each truck.
Why didn't they engage the rear locker in the Nissan? Can you not engage it unless you are in 4wd?
so did the rear diff's fail to lock on both the gm vechicles causing them to use 4wd, or did the rears engage and they still had to use 4wd? it sure looks like testers were trying keep them from locking in the suspiciously limited video of the gm vehicles. i have a hard time believing that a truck with a locked rear end couldn't make it up the hill in 2wd. makes me question this whole shoot out.
I'm not positive, but I think it's so that with heavy loads the bed can flex slightly without effecting the rest of the body. I have heard that some of the ford unibody trucks made in the early 60's had problems when hauling heavy loads. The door gaps would flex so much that the doors would pop open while driving. That is probably why today's unibodies are usually meant for pretty light hauling.
You guys should make this test again with the new models, and do SUV's too cuz all the videos out there on favor Subaru
We need this kind of update, for this year’s pickups
Where is this test track? Id like to visit someday.
what also makes a big difference is the type of tires and the type of LSD that is utilized. try a truetrac in the chevy instead of the gov lock and see what happens.
Just patiently waiting for an updated test
I find it only safe to assume If it's a test of the preformance of the STOCK truck the way it come's when you pick it up, Then No their should not be the same tire placed on the truck. This video is pointed to a dealer ship pick up turn key and go.
I wonder what type of tire they are using for these vehicle tests. the right tire can make a HUGE difference.
Can you do the 2013 trucks they all say the have upgraded theyre systems
Hard to believe it's 2020 already
2:27 - 2:38 Did you hit that certain RPM? I was under the impression that a locker is better than LSD........
The type of tire plays the biggest role in traction. Were you using the same tire on each Truck?
i can't post the link. so search: Mega Test Dodge Ram vs. Ford 350 vs. GM. first thing in the test shows how a 2wd with a locked rear end can get up a slick surface better than a 4wd with open diffs
@alldayandnight09 All tests they performed are done using stock tires, unless they specify a reason not to use them.
why'd they put the Chevy's to the wood? Heck turn TC off or apply power slowly. basically slip, lock, go if you don't try to do a burnout
It’s sad that you need traction control to do anything
@FreeSkier155 thats the whole point of this traction test, how well can the vehicle traction is without putting it in 4WD.
I think you just hit the nail on the head, my friend.
Agreed i drive 94 ford F150 and i live in the Minnesota. In snow I cant make it through the trail my dads Chevy makes in 2wd with his Chevy which has locking differential when im in 4wd. my truck has open rear and limited slip front.
@FreeSkier155 Well you are right, but if you are going up a hill during winter and there are cars behind, the last thing you want to do is have to stop and pop the truck in 4x4 to make it up a hill. It could cause an accident from your truck sliding backwards if you stop too quickly from panic or begin to slip back before you can get it in 4x4. This test shows which truck would be most reliable in this scenario, which is just one of many.
Was it the same driver for each vehicle? I have seen many many occasions where switching to a driver that knows how to maneuver these situation makes a truck that looks useless go to gold
@sokodad fair enough, I'm not a fan of chevy/gm, i like a more sophisticated look if that's the right word?
To see how well the rear differentials work on their own. 2WD gives better gas mileage than 4WD, so it's nice to know what a truck can do with it.
You really have to take in consideration, are they using the same tires on all trucks? are all the tires air pressure the same?
The Titan would have cam first if it's e -locker was engaged, and the silverado did the second best as you can clearly see the tire on the ashfault spinning (it just wasn't as heavy)
If you look closely, the GMC and the chevys tires lock up almost immediately. Because there is equal power going to both tires on different surfaces, the rear end starts to go sideways. This is why a lot of drifters use an E-locker or a stout LSD. An LSD just makes more sense for this kind of test. It distributes the power accordingly to how much grip each tire has rather than just locking them at the same speed. The outcome may have been different if both tires were on the slick surface.
Hang on, did the G80 not engage on the GM turcks?
I like that they keep it fair in that all the trucks were equipped with off road packages except for the Ford but it sill managed without it
If you live in conditions for a 4X4 you are not going to drive in the snow or iced roads in 2 wheel drive. I understand testing the Traction Control but that is why they have 4 wheel drive so the Traction Control doesn't have to work so hard. Maybe if they re did the test where you drive through a wet patch requiring Traction Control to activate. Or does anyone have an explanation for this type of test?
At 2:21 you can see the Chevy truck's rear wheel on asphalt. It's spinning like crazy, so the wheel with traction is getting plenty of power. It's just that that one tire could not get the truck up the hill. Seems to me more like a tire or weight problem, than a traction control problem.
I have 2011 Silverado z71 4x4 never had major problems
Mechanical diffs lockers are trickier to use, but its more reliable and effective. GMs G80 has proved that since the beggining!
at certain points they are or can be built for racing
many of these new systems only engage lockers or lsd's when in 4wd...open diffs in 2wd this test as stated was purely to test traction control in 2wd
@PlottingMax because all of those arent available in the US.
my 1996 k2500 suburban with a g80 would walk right up that. how is a limited slip better than complete 50/50 power. ive used limited slip before and found that it takes a lot of wheel spin where my g80 takes a little and once locked stays that way until i completely let off the accelerator.
How are you gonna make the wheels the exact same size?
@possiblymeish not entirely true, some of the big three use plants there but its not solely outsourced
@finonm7 same here i have a 2009 f150 and it does have a traction off button button it still engages when i spin the tires just delayed a bit longer which sucks ass
i was thinking the same. sure looked like they were trying to keep the rear from locking.
Sierra is made by GMC, (General Motors Corporation), which is in great partnership with Chevrolet, therefore they make very similar models of 2 different makes. Almost like Ford and Mazda, but yes. They particularly the same trucks, just some different exterior features.
@The415guy So you mean trucks should be fixed or repaired daily?
I would think the gmc/chevy with the locking diff would do as well as the TC on the tundra and ford no? as soon as they hit the slip RPM the locker would engage and the tire on the pavement would propel the vehicle to the top.
My 2017 Sierra Denali pickup slides out of control in 4WD in any type of snowy conditions and doesn't handle much better in the rain. I just saw I have traction control and now I am not sure if it was off or on. Now it's summer and I can't try it out both ways. However, it almost killed me spinning out of control. GMC service can't duplicate the problem and says it appear to be working OK. GMC customer service sucks. Thoughts or suggestions? This truck is going to kill me, someone else, or all of us.
That's only with a helical diff, with a mechanical or viscous LSD the wheel with traction will always get some power, even if the other wheel is off the ground. The other way to get around this with a helical diff is to gently apply the brakes, this keeps some strain in the wheel off the ground and allows power to be transferred to the wheel with grip.
