Earliest central tire inflators--I believe.

That's simply not true.

I own one.

Took it to a Porsche Club Drivers Skills event. Skid pad, accident avoidance, autocross, etc.

Tried to get it to misbehave. Couldn't.

My guess is that since you sit in the rear, engine in the front, it's actually a very good weight distribution. Total contact patches front and rear seem to be about the same. Very neutral handling....and a hoot to drive.

close, they keep positive pressure on the differentials to prevent water entering the axles

Seems plausible but why the limb to the (presumably) valve stem?



Kinda random:

Remote tire inflators. Decrease pressure for soft sand, increase for traveling on hard surfaces.

Advance to the 26:00 mark.

Fascinating stuff and thanks for that find it on the video. It seems like maybe you're both correct it definitely raises and lowers the tire pressures, but the video also claims to "pressurize the axle."

Before I watched that part of the video, and once it was suggested that it was for tire pressure, I was thinking perhaps they could compensate for heavier loads (and where those loads were placed) by raising and lowering the pressure, but it appears to have raised and lowered them all simultaneously.

Under ideal circumstances the axles are only a couple feet below the surface of the water where they wouldn't see that much pressure beyond normal. Any deeper and you're swimming to shore and water in the differential would be your last concern. Later models did indeed use the differential housing as part of the pressure pathway reducing much of the exposed plumbing and accomplishes both tasks.

Stopped in traffic yesterday on the 101 S in Santa Barbara. It could have been a whole lot worse...
