Hi,

LSD is not permanent thing on any vehicle.

I'm pretty sure your other posts have done a good job of keeping us all
up to date on your increasing displeasure at FHI in general and the new
Imprezas specifically. How many more disappointing details on Subaru
cars will be required for you to just give up completely and leave?

Actually VDC is a much better system than any LSD.

Hi,

What does that supposed to mean?
Hi,

Look into how LSD works, then you'll understand.

I think I do: it prevents wheel spin in situations when 2
front wheels lost traction and 1 of the rear wheels completely
or fully lost traction. With LSD the other rear wheel will still
get partially powered and on the new Subarus you'd have a
wheelspin.

The rear LSD distributes torque between the two rear wheels
independently of what's going on with the front wheels.

Am I missing something?
Is there some magical way that VDC would apply brakes
in such a way that the power will be delivered to the
wheels that have remaining grip?

This is, in fact, the point of VDC and has been around in various
forms for more than a decade. VDC monitors the ABS sensors and can
apply the brake of a spinning wheel to allow torque to reach the other
wheel. VDC does other things, as well, but this is how it can
electronically "lock" a differential.

This is certainly a more complicated traction solution than a purely-
mechanical LSD and you can argue that it is comparatively less reliable.
But it has a considerable weight advantage. Eventually, it should also
cost less, once it becomes more commonly available.

You mean _considerably_ less reliable?

No, I do not mean "considerably."

I don't mean as in "a nuclear blast takes out all the electronics" but
as
in the oldie Outback vs Vulva cros country video with the vulva
spinning the rear wheels ever so slightly on a modest muddy uphill
and after being graced with a trailer?
I'm sure that Vulva in the video had VDC among other things: did not
help a squat
to keep that pig going though.

I've never heard of a "Vulva cross country."

Quote:

Does it work?

Yes, it works. Think of it in conceptual terms. An open differential
loses traction when one wheel breaks free and all of the power is
directed to it. It's simply a by-product of the way a traditional
differential functions. If you can return resistance to that wheel,
whether by regaining traction or applying its brake, then power *will*
return to the other wheel. VDC is scheme for accomplishing this.
Furthermore, it can be applied to *all* of the wheels, not just the
rear.

Going back to reliability, more complex systems are generally more prone
to failure than less complex ones. But it's rarely that simple. If
your LSD breaks, you can't drive the car. It's busted. If VDC breaks,
it merely turns itself off and you can keep driving.

You show great ignorance of the VDC system if you think it is only a $3

chip. It is actually a very sophisticated 'total' vehicle application. VDC
controls the engine, transmission, differentials, and brake system and has
components in each of these systems. It also includes accelerometers that
allow the VDC system to determine what forces are acting on the vehicle, and
in which direction. Along with the steering wheel sensor, the VDC system is
able to determine if the vehicle is going in the direction the driver
intends (or doesn't intend) for it to go. A simple visit to the Subaru
website, or review of any Subaru service manual or technical manual will
reveal to you how much more than a '$3 chip" the system really is.

What's to stop somebody installing a LSD on their car after they purchase it
and if it's really so great a necessity why not just do this? Any chances a
LSD could throw off the proper functioning of VDC?

I have a sudden jolt of creativity.
Don't you know I don't give shit about political correctness?
I expect some respect from FHI for the intelligence of their
clientele (and prospective clientele) and since I'm not getting
any I feel I'm entitled to 'WHINE' (loudly).

No, but every single Merc owner I'm aware of has had problems of one sort
or
another with their vehicles. Parts are needlessly expensive, the
engineering is needlessly complex, and you end up forking out huge dollars
primarily for the symbol on the front of your car.

If VDC were superior then it would be on the higher-end rally cars. It's
not, both ways. (This is something which the OP is sitting there agog
about
I'm sure wondering why you guys are defending VDC..)

Not so. If the rally drivers need something like VDC, they would have it.
Besides, Launch Control (which they DO have) is a similar principle.
