*Please note: In this video I have incorrectly mentioned that Torque is distributed/split based on wheel resistance. In reality, in an open differential Torque is split evenly 50%-50% to each axle regardless of wheel resistance. However, Power is split based on wheel resistance in an open differential, not Torque. Power = Torque x Angular Velocity. Therefore, in an open differential, if a wheel is in the air and freely spinning, the other wheel which isn't rotating isn't transmitting any Power (as Angular Velocity = 0, but Torque is still present). Watch out for a future video which further clarifies this.

Great video, mate ! This is the most comprehensive panorama of the topic I've ever seen. As a follow-up, you might want to cover the gearing system in the wheel hubs of Unimogs and Hummers. My first offroad fun was in 1974 in Ethiopia driving a Gaz, a robust Russian military jeep: side-valve engine, 3 forward gears, part-time 4WD with high and low ratios, + freewheeling hubs. I had incredible adventures especially in the Danakil Desert.

I have never driven any 4 wheeled vehicle, yet this video is informative and very easy to understand for me, you have explained it perfectly with animated diagrams and real sample drives!! well done and thank you!!

Hi, very well made video, although I noticed a mistake on 3:30 minute mark about open diffs. It will be easier to explain if I just directly quote from CarThrottle website. "Open differentials are the most basic form of a differential. The purpose is to allow for different speeds between the two wheels, while torque split is held constant at 50/50. A common misconception with open differentials is that when one wheel is lifted, 100 per cent of the torque is sent to it. This is not true, however the amount of torque sent to the wheel with traction is very low because the amount of torque required to spin a wheel is also low. Remember, both wheels always receive equal torque, but if one has no resistance (eg. if it’s in the air), the amount of torque sent to the drive axle as a result is very low." So, open diff will always split the torque 50/50, even if one wheel is off the ground. We just get the illusion that 100% of the torque is going to one wheel because it is spinning but in reality diff is still applying the same ammount of torque to the non-spinning wheel (It is still trying to turn it). There is also a mistake in the video about locked rear diff. I will quote again: "Locked differentials are on the opposite side of the spectrum versus open diffs. The purpose is for wheel speed to remain constant between the two wheels, and the major benefit here is that torque will go to the wheel with traction, up to 100 per cent at a single wheel." That means that when the rear diff is locked, torque is not split 50/50 (that's open diff), but it varies up to 100% on one wheel. For example if one wheel is in the air, wheel on the ground will get 100% of the torque. Or if one wheel is on the ice and other on pavement, the wheel on the ice will get lets say 23% of the torque while wheel on the pavement will get the remaining 77%. Engineering Explained goes really in depth on this topic, I recommend watching some of his videos about this. This one is good: kzread.info/dash/bejne/kXyDw5Kagr2_oNo.html&ab_channel=EngineeringExplained

Your explanation is more true, but a bit harder to understand for someone who hasn't had a more higher class in physics. I get however what NJS is talking about. That way it's easier to understand for me (as a noob) what's happening. It would've been better if he didn't use the phrase 'torque', but more something like 'movement or momentum'. However, thinking about that, it could also be interpreted wrong. The video's from engineer explained go waaaay more in depth and use all the correct terms and calculations, but are harder to convert to driving in the real world. NJS covers way more topics in the same time that Engineering explained used to talk only about diffs.

I am new to 4wd and this is the 2nd video ive watched about 4wd systems, and it doesnt make much sense. This comment that i am replying to might be a little more comolicated then the video, but aeast it makes sense. This video was saying that open diffs have a big flaw, and closed diffs have a big flaw which dosent nake much sense, since cars are to old to have big problems like that. How it was explained makes it sound like a really ineffective design, almost like a new technology, which it's not. With that being said, is it really that bad to go on grippy surfaces in 4wd if torque is applied differently and the wheels are spinning at different speeds if its a locked diff? Am i missing something or what?
