Torsen AWD Vs Haldex AWD/XWD

[ds.raikkonen]

So nobody here knows about the T-2/T-3 type Torsen

The definite weapon, IMHO, would be a Jimmy with differential lock and proper tires. That will go through anything

Or maybe BX 4x4
That car was very light for it's size.
I think most variants were under 1000kg.

I raise you Lada Niva. Probably same weight as Jimmy, low gears, full time 4x4 with diff lock and many models come with off-road tyres that are more for a backhoe than a highway capable road car. The thing is downright UNSTOPPABLE.

According to wikipedia the Niva weight between 800 and 900kg, so yeah, that´s a winner.... at least for off-road use, because if the Jimmy is far from a comfortable car for road use, that Lada... but for off-road use I think there´s no other standard production car wich comes even close. Most of them lack diff lock, or their weight is around double of the Niva

I think that's a safe assumption.

Overall they are really good, much better than a Torsen type diff for track use where you might lift a wheel off a ripple strip or simply through cornering, especially an a FWD or 2WD car.

They also seemed to be a little more like a 1.5 way plate diff under braking but that might have been just my "seat of the pants dyno" perception.

I think that if you were to use one you'd use the optional higher friction surfaces to get it to lock up with a bit more quickly and positively.

You're spot on about the ripple strips. I've felt FWD cars surge over them due to the traction difference. Haldex clutches are best suited to counter this phenomenon. So are the Torsen diffs are better suited for torque distribution in AWD applications or is it just a myth?

My personal opinion is Torsen diffs are a compromise for semi track/road cars. They are good but definitely a compromise vs a plate or Salisbury type LSD.

Then again, living with a plate diff in a daily is less than ideal..

That's the reason why I believe the T-3 type Torsen is better than clutch type LSDs, albeit more expensive. That's why cars like A3/TT use Haldex type Quattro and A4 onwards use Torsen type.

It has always been my understanding that Audi's choice of Haldex vs Torsen was down to the engine being transverse or longitudinal and the associated packaging - transverse ('native' fwd) engined A3/Golf etc. used Haldex, whereas longitudunal ('native' rwd) engined A4 used Torsen.
