120mpg way back in the day. Swoopy but not all that aero. But the small frontal area is tough to beat.

I'll see if I can find a pic...
They're supposed to be for crosswind stability,killing any chance for a yawing moment by forcing separation at the 'fang.'
They'd also kill crosswind bi-stable flow-induced flutter.

In this infographic they appear in the lower right as 'vortex traps'.

JACG:There were some mighty big Goodyears on Admiral Byrd’s Antarctic Snow Cruiser in 1939

It was an aircraft carrier. A little touch-up on the wheelwells and a boat tail is all it needs. It couldn't make 13mph.

I don't think height off the pavement is the biggest thing working against this rear diffuser, maybe a possible messy underbelly that I have not seen is.

Interesting '86 944 Turbo Widebody - Pelican Parts Technical BBS



Your take?

If you read some of the comments you get an idea of the debate over it.

Where it says PORSCHE on the side sure looks like a side skit to me.



The rocker panel does sitck out more in the one first posted, makes the door look like it's set back, not flush.

Another black 944

A lot less drag and weight on the stock car, I'll say that much.

I have an idea or two but want to see if it matches anyone else's ideas.
my guess is that the sub is seldom the traveling in a straight line, so straight forward Hydro Dynamics would not apply. There may be less turbulence/ noise while turning.

Agree. The fences fall short. You can see clear through the off-side wheel. And the diffuser only fills the middle two quarters of the rear.

Chris Runge is at it again:
