The 4th generation 4Runners with 4WD came standard with a Torsen Limited-Slip Center Differential that could be locked. Although I haven't seen the Torsen LSC Differential mentioned as a feature in any of the leaked PDFs, I doubt that Toyota eliminated this feature. I agree with JB that it would be a strange move backwards, kinda like dropping the the V8 for a four banger. But then again Toyota did say the 4Runner would "return to it roots."
Yes back to its roots.
I betting that this thursday the debut will reveal...
No multi-mode 4WD transfer option at all.
Its either part time 2 speed transfer or full time 4WD with no option to use low with the center diff unlocked.
Probably the Limited will be the only version with the torsen center diff. This returns the Limited back to something more than a $4000 increase in price for just leather seats, larger wheels, dual zone a/c and some small stuff like auto headlights and lighted gauge needles. Back in 99 the price increase for the limited actually bought you something such as automatic climate control, multi-mode 4WD and larger flares. I never understood why Toyota put all the goodies on even an SR5 for the 4th gen, not much incentive to upgrade to the Limited.
The problem with the 5th gen for me is I cannot find a model I would actually buy right now. No version comes with the V8, which how can you downgrade after owning one. The Trail Edition...while the e-locker, hood scoop, crawl control, waterproof seats, and kdss are great...its required to get the sunroof and only has part time 4WD. The Limited is the only way to get the full time 4WD but comes with 20's, skirted bumpers, small flares and cannot be optioned with the TE's offroad goodies.
Well I will look forward to the refreshed version in 2013 and hope for the following...A TE with the 4.6L V8, no sunroof, multi-mode 4WD, control of the center diff lock via a button, projector headlamps and fogs, Leds all around.
Check my 2010 4Runner History page for more specs you may not have seen elsewhere, like the fact that you can get footwell lighting optionally though only up front.
