Perforated Volkswagen Jetta - photo

Somebody had a lot of excess time on their hands to strip all of the plastic out and perforate the body and it looks like much of the structure as well.
I wonder what it weighs now?

How well does that work in rain and snow? Asking for a friend...

How many HP would that add? ;)

It wouldn't actually add any HP. The weight reduction would increase the HP to weight ratio, the weight reduction would also show a slight increase of fuel economy as long as the speed was kept below the point of creating wind turbulence due to the wind passing through the holes. Above a certain speed the turbulence would cancel out any fuel savings from the lighter vehicle and the fuel consumption would be more than had the car been left alone

Saved me the trouble, and stated it better than I could have. ;)

You will find that when there are a lot of small holes they will pack up and pretty much not be effective at high speeds. The only areas where they will be effective is the lowest pressure areas usually at the back. So the amount of air through them will be dictated by the amount of air that will flow out the few holes in the back that have the lowest air pressure due to drag turbulence.
I do a lot of work with pipes in loudspeaker boxes. It is sometimes amazing how these things react depending on the air speed.

The noise must be outrageous when driving. Can you change spark plugs and add fluids without popping the hood too?
