1969 was the first year for fixed wind wings on 911 and 912 Porsche passenger coupe’ models.
This highly visible component, among others, makes it easier to determine if the car is a 1969 or later model.
Hinged, movable wind wings go all the way back to the earliest Porsches. They were a great way to push a lot of air into the passenger compartment at speed.
But they also pushed in a lot of wind noise when they were fully opened. On rainy days the wind noise was often wet wind noise.
Even partially opened, wind “whistle” was a bother to many.
If wind wing noise at either “high roar” or “low whistle” positions weren’t enough, some movable wind wings would leak if the rubber seals around them were worn, cracked or otherwise damaged.
If part of the small movable handle was accidentally damaged or broken off completely, a roll of duct tape might have been a nice thing to have in the garage.
In 1969, no more wind wing noise problem. Porsche eliminated all these real and potential problems by sealing the wind wing entirely on all Coupe’ models, as you can see in the photos below.
No more wind wing noise problem.
For reasons presently unknown to me, the movable 1969 and later Targa wind wings were retained.
I haven’t looked into this because I’ve never owned a Targa. But if someone has, please enlighten me via my Facebook page (Mike-Newlons-Books-About-Classic-Cars-on-Todays-US-Highways/) or my web site at http://www.highwaytripbooks.com.
As you can see from the photo below, of the interior right side, the absence of the old curved metal frame and wind wing “turn and lock” knob in earlier models gave the 1969 and later coupe’ interiors a much cleaner look, too.
But what about interior ventilation with the new fixed wind wings?
Come back soon and find out!
