Hi lux Invincible limited slip diff and 4x4 workings
Discussion
Considering buying a new 2015 Toyota Hi lux Invincible. I want something that has good off-road capability. I note the Invincible has rear limited slip diff where the other models have a manually selected rear diff. I would have thought the manually selected would be better. Any comments? Does the invincible have automatic 4wd or is it selectable? Any other comments about the Invincible 4wd workings and performance would be a help.
Is a manual locking diff "better" than a limited-slip? Well, that depends for what.
A limited-slip diff will be of benefit on tarmac, and will keep the two wheels within a certain percentage of speed of each other.
A manual locker will be of absolutely zero benefit on tarmac, and will lock the two wheels absolutely to each other off-road.
A limited-slip should still get you out of a situation where one rear is just spinning uselessly in mud or mid-air.

How hard are you planning on using it, off-road, that the difference between LSD and a manual locker is even remotely likely to make a difference?What tyres are you thinking of putting on it? Big chunky (lousy on-road) rubber will make a bigger difference even in less challenging conditions, and will stop you needing either until you get into conditions that you'd be WELL stuck on road rubber.

I was thinking General Grabber AT, ok on the road and reasonable off road. I didn't have a locking rear diff on my TDV8 RR and the traction control was always chattering away in soft mud even with the general grabbers fitted. Just want to get a better idea of how the Invincible system works to make an informed decision. Unfortunately showroom salesman not up to the tek spec, other than continually saying its good.What tyres are you thinking of putting on it?

Which is just telling you that at least one tyre's slipping a bit.With a locked centre diff and a locked rear diff, you'd need at least three tyres to be contributing absolutely nothing before forward motion ceases.
With an LSD on the back, make that at least two doing nothing, and a third doing next-to-nothing.
With a locked centre and a totally open rear, you only need one each end to be doing nothing and you're stationary.
With all three diffs open, any one tyre can lose all motion.
L322 Rangie has open axle diffs, and a Torsen LSD centre, then electronics to do the rest.

Yes tried new RR with locking rear diff option and much less fan fare in the slippy stuff.With a locked centre diff and a locked rear diff, you'd need at least three tyres to be contributing absolutely nothing before forward motion ceases.

When is this happening? I thought it was 18 months away.
Next year!! There are spy shots of pre production trucks on the net ,mine has the manual locker useful off road others have a tame (not much preload) LSD better on road than off but as others have said its all about the tyres but if you're a serious off roader you can buy an arb locker along with better under body protection and lifting the front.The main advantage of a selectable manual locking diff over an LSD off road is that you can lock the diff before you lose traction which in theory should help you maintain momentum. The LSD only starts to lock the diff when one of the wheels starts spinning.
I would prefer to be able to lock the diff before I got stuck rather than after

In my experience of hard core off road use a full locking diff does better than an LSD (Limited slip diff). Friends of mine have noticed the same and also upgraded their diffs from LSD to full locking.
But a locking diff cannot be used on the road though, which is where most "normal" people want the extra traction, for safety, like driving in snow or in bad weather.
Traction control, I've never used it, but apparently isn't close to 100% effective yet. There's some decent experiments recorded on Youtube which show traction control to be really lousy, slow, and not living up to its claims.
