Agree - lack of roof edge rain guttering isn’t specific to the 6r / 6c Polo. Pretty much no other cars - VW’s model range or cars produced by any other manufacturer - have these nowadays. I think the last car I had with roof edge rain guttering was a Vauxhall Nova GTE back in the early 1990’s.RUM4MO wrote: ↑Wed Sep 02, 2020 10:28 pm Veteran, my comments about rain channels was aimed at indicating that some cars do have water management measures built in and some of them also reduce wind noise, which is the real topic of this thread, in a world where all or nearly all new cars don't have any roof edge guttering, water will always end up flowing into the car, when you open a door, or open a window while water is present on the roof area of the car, any water management measures will at best only work when the car is parked on level ground. It is just lack of thought or lack of rain where car body designer live?
I’m assuming there are aerodynamic gains by not having these, and car designers will place more importance on aerodynamics and reduced drag than water rolling off the roof into the car through an open window.
