There is something very romantic about the old idea of driving your classic Porsche 911 to the beach with a surfboard on the roof.
Porsches have, over the 50 years of the 911’s history, been fitted with some enormous inverted wings.
Today’s invention is therefore a surfboard which can be carried on your sportscar (laterally) but which acts as a detachable downforce wing, when the car is in motion.
