Hi Hankypanky...This Ferrari is indeed electric powered( good that you saw this),strong competition for the US Tesla. The rear window panels are for solar energy and removable, the parts at side are for the downforce of the rear. Is this placement perfect for the aerodynamics? I'm not sure, but this was a fast (+- 1 min.) concept sketch to explore a new shape for a future electric Ferrari. Render was much longer then 1 min. thanks to comment !
