The Superbird was also made for NASCAR, and RWD. The Ford Focus's, the Neons, and the Civics I see with giant wings are FWD. The wings server no functional purpose.
Also, the Wing cars wings were so big, so the trunk could open. However, the big spoilers I'm talking about are attached to the trunk.
I hate to keep advocating for the sport compacts but I want to just make a few more points;
* The dealers couldn't give away the Superbirds and Daytona Chargers when they were new. I keep seeing feature stories on these cars where the dealers made their wives drive them until the complaining became unbearable or they sat on lots for a year or more until the dealer basically gave them away to get rid or them or they removed the wings and nose cones to turn them back into standard models. Those cars pretty much equate to the winged and ground effect bedeck cars of today. It's just that tastes have changed and that kind of stuff is popular now where it wasn't in the 60's and 70's.
* Yes the Superbird wing was designed for NASCAR racing. The wings you see on sport compacts were orignally designed for SCCA, World Touring Car or World Rally racing vehicles which many of the popular sport compacts compete in. These are every bit as serious a racing series as NASCAR. Granted they have little or no function at legal road speeds but neither does the Superbird wing or Go-wing on a Cuda or Challenger. They are there as a styling image enhancer.
* I was in high school at the peak of the muscle car boom in the late 60's (graduated in 71). There were many more 6cyl/2bblv8 A-body, B-body and brand x cars in the parking lot with chrome reverse wheels, glass paks, jacked up rear ends than there was true muscle cars. I don't see that time has changed at all. There are those that had the money to get the real thing and those that took what they had and tried to build an image, same holds true today.
