While the Cybertruck’s styling certainly lends itself to a sharply inclined tonneau cover, the aesthetics of arguably every other vehicle on the market do not, and this is why aerodynamic canopies or bed covers have not taken off in popularity.
To get around the problem (and ultimately maximize aerodynamic efficiency), Ford’s design retracts both the tonneau cover and the tonneau cover’s rail supports, creating a clean look when the tonneau cover is stowed. In addition, the supports include fins to further enhance slipperiness and aesthetics when the tonneau cover is deployed.
Another thing that sets this design apart from that of the Cybertruck – or pretty much any tonneau cover – is that it features an access window for stowing cargo easily/carrying taller items. Naturally, the tailgate opens independently, but there’s yet another trick this design employs, and it’s the best one so far.
