Interesting Aerodynamic Cars (Mike Vetter's ETV, also Avion)

Trailer/tow vehicle gap doesn't get much better than this:


Just A Car Guy: I haven't seen anything this cool in a while

But the soap box derby racer would be faster backwards.

I wonder how hard that trailer kissed that car?

In pitch roll or yaw?

I think it's a ball-and-socket arrangement.

[Frank Lee]

Pitch, mainly. Can't imagine cresting any sort of hill without things going crunch back there. Maybe there's no trunk lid and the nose of the trailer is narrow so it's OK when straight. Just no fancy maneuvers and no challenging terrain.

Check out the underside--even the control arms are faired:



Three-position spoiler (parked, Eco, Performance):

Porsche's press release says the base Turbo has Cd 0.22 and the Turbo S Cd 0.25. I haven't seen either in person, so I'm not sure what the differences are between them. The Chicago Auto Show website says the Taycan will be on display, so I'll see it there.

It's a Curtis-Wright.

This reminds me of my Clark-Cortez, only more extreme:

Nothing says raw power like half the engine sticking through the hood.

The shell is a decent aerodynamic shape, and the wheels are as good as unfaired wheels can be - but the rollcage and engine are distinctly poor drag.

The exhaust location is interesting, and useful, though.
