Semi-truck sized air horn.:)JK, yet sounds like fun.No go, would totally screw up the drag coefficient w/ some huge air horn on the body.
take the whole power train of the aptera and place it into a classic car while keeping the stock V8. Creating an overpowered hybrid.
Trunk liner and floor mats.
Hornblasters brand is best! I have a Shocker XL kit on my Civic... 150PSI.
It has four trumpets but maybe just one would fit under the hood of an Aptera.. then find a place for the tank and air compressor.
Put it inside...😬
