Engineering a convertible isn’t an easy task. Chopping the roof off a car adds all kinds of complications from big ones like chassis rigidity, to smaller ones, like keeping the cabin calm with the top down. For decades, that latter issue has been handled with some kind of wind deflector behind the front occupants. While some cars have had fancy power retractable ones, all too often they’re ugly, fiddly pieces of plastic that snap into place. Depending on how things go with a new patent, however, the days of these deflectors might be over for Porsche 911 and Boxster convertibles.
