wwest which drive system is better the one on the Highlander now or the new one on the Venza, Sienna etc.? As for DFI yes I think that is the wavy of the future in engines but due to Toyota's problems of late I don't expect to see that for a couple of years (I may be wrong). Anyway I was thinking on the lines of if the 2011 well have memory seats, 6 speed auto, HID's etc...

The current HL, as did the previous RX, uses three "simple" open differentials. All four wheels are driven as long as all four have roughly equal, high or low, roadbed traction. Should one wheel slip then TC, Traction Control, braking is used to "restrain" that wheel in order to simulate traction and thereby maintain engine torque at a high enough level for the non-slipping, tractive, wheels to get/keep you moving.
When TC activates in this manner the engine also gets dethrottled instantly.
The new system "PRO-ACTIVELY" couples a variable (condition dependent) level of engine torque to the rear any time you accelerate from a low speed, below ~25MPH, to a higher speed, or need extra torque to start moving, towing, hill, etc.
Regretably if/when that doesn't work the system reverts to TC braking and full engine DETHROTTLING.
But progress is progress.
6 speed auto, yes, memory seats, HID, there's always Ebay.
Toyota has a vested interest in not "stealing" Lexus Rx sales.

Thanks wwest that was a very informative and easy to understand explanation. It does sound like a bit of a wash between the two systems.Though the new system make have a slight edge. I am use to a 2004 Subaru Forester XT which works very well but at 57 I really like the quiet and smooth ride of the Highlander Limited. Also we have driven Toyota's since 1981 and my wife would like to see me get back to a Toyota. We still have the 2001 Avalon XLS and she well not give that up for anything. If the 2011 has the 6 speed I think I may have to wait.

Were I to purchase one of the new F/awd systems it would immediately get a switch wherein the rear clutch could be manually engaged in times of need.

What is the story with the Highlander Hybrid rear wheel, does it send power there normally?
The way I see it, wait until 2011 HL specs come out before doing anything.

It is my understanding that the F/awd HH and RXh will NORMALLY power the rear wheels only during acceleration. Other than that I don't know.

I was told by one salesman that there is a slight redesign for the 2011 highlander and another salesman told me that there will be no styling changes.
I am in the market for a new vehicle but I don't want to spend 49k on a vehicle that may be redesigned and available within a month or so.

For some, adoption of the F/awd system might be considered a "slight redesign".
No visual difference, except underside.

for a first (partial) look of the 2011 Highlander, the reveal may come the Moscow Auto Show on August 25th in three weeks. Reportedly the US version will be virtually the same. Refer to this link:http://www.autoblog.com/2010/08/06/first-look-2011-toyota-highlander-to-lau- nch-at-moscow-motor-sho/
