[s-cars] future of awd

[Taka Mizutani]

Scott-
One thing- until the Haldex engineers install a cooling system for the
Haldex, it's a liability at the track. The V70R forum is full of people who
have tracked their cars and experienced Haldex overheating and shutdown. The
car goes to FWD only when that happens, without any real warning.

I would not track any car with Haldex for that reason alone, until someone
figures out how to cool the system down so that it does not overheat.

Note that this doesn't happen on the street, but in the extreme environment
of track days and experienced drivers pushing the car to its limits,
probably with R compound tires and race pads. (most likely so, considering
the same guys heat their calipers to the point that the grey paint becomes
burnt orange)
