I was in motion when the rain started. Usually (on other cars) there is a turbulence at the back that makes the back window wet in a random fashion. Where as the rear window on the mercedes was completely dry.
Do you think the 85 w123 mercedes was designed with the knowledge about Hucho? The car was first produced in the mid 70's I believe.

We had a 300 TD in the family and it was Mercedes 'coming-out' car for aero.Their print media advertising went to special pains to illustrate all the wind tunnel development work which went into the production car.Right down to the non-fouling taillight lenses.
With the higher and longer boot,the trailing edge of the trunklid would prevent any splash or spray from the wake to migrate up and over to the backlight.
The transverse locked-vortex atop the trunklid would spin-dry the water out of the air before it could circulate back to the glass,leaving only the spinning air to lick the surface.
The water is 833X as dense as the air and it's inertia-momentum won't allow it the aerobatic freedom the air enjoys.It's simply benched on the sidelines .A good thing!
