front “diff” or not?

I have just been reading the post "Leaving in 4 wheel drive or not".
When the salesman was doing his "pitch" to me re the Outlander, he told me that the Outlander will go where my old Honda TRX would not go because it was "true 4WD", whereas the Honda was only 3 WD. I didn’t really ask for an explanation but assumed that the Honda had a front diff (delivering torque to the wheel with least resistance)whist the Outlander did not. Obviously it has a front gear housing but is it a differential or a straight bevel drive? Or, could be a limited slip diff but I doubt it!
Someone with a manual may be able to clarify.
If it is a straight bevel drive it would not be a good idea to leave it engaged when not needed.
The specs may vary from one model to another. Maybe the Outlander L450 is a "downmarket" model in an effort to reduce the price.
Any thoughts?
