i'm a mainer and currently own a 2006 V8 4runner (full-time 4WD) which is indispensable during the winter... i'm VERY interested to know what the reality is with the new 4runners' (lack of?) center differential (SR5 and Trail Edition) and if the 4WD can be used on-road... i've literally been waiting to buy the Trail Edition, but if it's going to be less sure-footed than my current 4Runner from December - April (yeah, that's almost half the year) i don't think i'll getting a new Toyota.

Here's another Toyota press release:
"SR5 and Trail 4x4 models have a two-speed lever-operated, part-time system with neutral position, while the 4Runner Limited is equipped with full-time, four-wheel-drive with a locking center differential and employs a three-mode, center console-mounted switch. The new 4Runner is also equipped with a stronger rear differential over the previous model, thanks to a gear ring that has increased in size from 7.87 to 8.18 inches.
To enhance grip, the A-TRAC system is now standard equipment on all 4x4 models. The system can distribute driving force to any one wheel in contact with the ground, making terrain irregularities and slippery patches transparent to the driver. An electronic-locking rear differential is standard on the Trail grade. Axles house 3.73 gears, or 4.56:1 with the 2.7-liter engine and the differential housings have improved seals for better resistance to mud and water.
Toyota’s Crawl Control (CRAWL) feature is standard on the Trail grade. CRAWL is an adjustable electro-mechanical system that can be tuned to match the terrain by selecting any of five speed levels. The system maintains an appropriate speed that keeps the vehicle under control and minimizes the load on drivetrain and suspension components. The CRAWL feature helps make traversing difficult terrain easier and safer. With the transfer case shifted into low range, Crawl Control regulates engine speed and output (along with braking force), to propel the vehicle forward or in reverse at one of the five low-speed settings. This allows the driver to maintain focus while steering over very rough level ground or steep grades, without having to also modulate the throttle, or brake, pedals.
The Trail grade also features a Multi-Terrain Select system which allows the 4x4 operator to dial in wheel slip control to match the terrain. In loose terrain such as mud and sand, more-than-normal wheel slip is permitted, allowing wheel-spin to work in the vehicle’s favor. On bumpy moguls, or solid rock, wheel slip is minimized and the system acts more like a limited slip. The Mogul setting is for any extremely uneven terrain, such as V-ditches, slopes, and ridges, uphill or down."

Sometimes manufacturer brochures are wrong and sometimes the "official" information contradicts itself. Press releases are notorious for getting things screwed up too.
I'm curious to see what the story is here.
Yup, I understand that. I, too, am curious to see what the story is here. But from what I've seen, in the Canadian market all trim lines get the Torsen center diff, while in the US only the Limited trim gets the Torsen center diff.
I hope that I'm wrong and your editor is right. But I'd really like to see some clarification from Toyota.

Poutine, Nanaimo bars, standard heated seats and Timmys....
Canadians get all the good stuff.
But my guess is that Toyota didn't screw up the specs you listed or the press release though.

That's my guess as well. Darnit. A Trail Edition with heated seats and a lockable Torsen center diff might be right up my alley.

I'm right there with you Steve. Here in New England, I won't buy a car without heated seats.
#2383 of 2493 Well, it has been confirmed
Sep 30, 2009 (3:33 am)
The 2010 4Runner SR5 and Trail Edition do NOT have a Torsen center differential. They have the VF2A transfer case. In other words, it is a part-time 4WD system that is not suitable for use on the road. Offroad only.
This is a major step backwards for the 4Runner.

Don't be so quick..!!
The shop manuals still show a "Torsen" type diff'l, perhaps a "clone" design (patent has run out..??) and not allowed use the "Torsen" name.

As of 2010 the 4runner can be ordered with a simple transfer case, PART-TIME 4WD, or with the Torsen, FULL-TIME R/AWD or PART-TIME selectable mode.
"...But..., frankly my dear, I don't give a damn!..."
Can someone tell me, PLEASE tell me, why full-time AWD/4WD is so all-fired desireable..??
IMMHO an IDEAL AWD system would be predominantly RWD and only couple drive torque to the front if the rear wheels begine to slip/spin. But in NO case should the front wheels be "driven", leading or lagging, with the brakes applied, in a tight turn, a low speed accelerating turn, or if should VSC activation be required.
The only full-time AWD that comes even close to that is the Acura SH-AWD system.
Think about it, if your vehicle has TC/TRAC, Traction Control, of what use is full-time AWD/4WD...?? Unless you have turned it off then the instant wheelspin/slip is detected TC will INSTANTLY moderately brake the slipping wheel(s) and just as INSTANTLY dethrottle the engine.
Yes, you could now turn TC off, but I would just as soon be in the TRUE 4runner and switch to a LOCKED center diff'l/transfer for teh duration of travel on the slippery surface.
