I found at this link:
the following, halfway down the page:
* Honda calls their all-wheel-drive system "Real Time 4-Wheel Drive."
According to Honda, "When there is insufficient traction at the front
wheels, the 'Real Time' 4WD system automatically uses dual hydraulic pumps
to transfer power to the rear wheels. There is no need for driver
intervention. The greater the degree of front-wheel slippage, the more
torque is directed to the rear wheels." *
AWD is a form of 4WD. Generally when people refer to a system as AWD they
are talking about a full time four wheel drive system or an automatically
engaged on-demand sytem that does not require driver intervention to
activate the 4WD. Often when people say 4WD, they are talking about a part
time system that requires manual engagement of the front drive axles. But
there are so many variations and shadings it is hard to make any definitive
statement about exactly what is an AWD system as opposed to the more general
4WD system. You might want to look at
Subarus have used several different AWD systems. Some have used a center
differential to allow for difference in the speed of the front and rear
axles. At least in recent year all of the Subaru systems can be
characterized as full time 4WD.
You did not mention what vintage CRV you own. The current Honda CRV System
is also a type of AWD. See
The current Honda system, although not the same as any particualr Subaru
system is most certainly modern and all wheel drive.
It seems to me that people who buy Subarus often have a "my 4WD car is
better than your 4WD car" attitude. I've never experienced the joy of
driving a Subaru, so I don't know if it is true or not. I have owned several
different AWD vehicles, but the ones I owned used the electronic clutch
method for allowing slippage between the front and rear wheels - essentially
an on demand type of system, sort of like what the CRV has - the four wheel
drive is essentially only active when there is slip between the front and
rear wheel. The Subaru system (at least for most current models) is always
engaged to some extent. Maybe this is useful in cold climates where you see
a lot of snow, but where I live the difference is trivial (or non-existent).
I think you don't need to care whether your AWD is better than your friend's
AWD. When theu say my AWD is better than your 4WD just smile and nod. I know
several years back Subaru ran TV ads that were designed to "prove" their 4WD
was better than the CRV 4WD in use at that time, but like a lot of ads, it
was mostly marketing BS that had little real world application.
I purposely didn't get the CrossTour because I thought it was ugly
looking and the starting price is 30,000 without AWD. I think thats a
lot since the Pilot started at around 27,000. I wanted a lot of
comfort features without paying 6-7k more than what I already spent.
The price I spent on my CRV with all the options I got was just about
29k and I thought that was a little more than I wanted to spend.
Just an observation here. 26 years in the army I have been in a
number of Jeeps and other 4WD vehicles. My wife and I have twin Jeep
Grand Cherokees (4WD,) which we now drive in the Sierra Nevada. We
also now own a 2010 Honda Pilot Touring (AWD.) We have had both
vehicles on severe slopes, on highway 1, up to a ranch, on dirt roads,
and if you know highway 1, on the coast of California, you know.
Anyway, I have placed the Jeep in "all-time" 4WD (meaning that there
is some slippage, so the tires don't get scrubbed) and only one time,
in severe snow, in the Sierra, in "part-time" 4WD, meaning that the
tires (final drives) are locked and they all pull together. The
difference is very obvious. We've had only two trips, on the same
route, in the Honda and I have to say that we have never noticed when
it went into AWD (if it has ever gone into AWD!) So the Honda is a
generation ahead, and we much prefer it, on this trip. But (and there
is always a but) we have not driven it in the snow, and to be
truthful, I have not dared, not knowing what the AWD will do. If it
kicks in will I be crosswise on a narrow mountain road, with a hundred
foot drop off? So for the last year (the only year that we owned it)
I picked the Jeep, in the snow, with the 4WD that I know. I get to
pick the gear, the 4WD position, and I know what I am getting. Maybe
the Honda AWD is better, in the snow. I don't know. I am actually
afraid to try it. The road that I am on, US 50, from Sacramento to
South Lake Tahoe is absolutely notorious for killing motorists in the
winter. So there you go. I have both types of vehicles and I don't
I haven't had any issues in snow with any of the AWD cars I've had. Subarus,
Hyundai's and BMWs have all performed quite well. Course your definition of
snow is probably different than mine. I haven't tried any of them in
waist-high drifts. I live in the NE part of the US so I haven't really
driven in more than a foot of snow.
