It’s just the rear wing of a McLaren car but there is so much engineering in here! It can contract and expand according to the driver needs, the speed of the car and the external conditions (weather and road ones). It is not amazing just from the mechanical side of view but also from the sensors and electronics that are controlling it. And on top of all of those, the rear carbon fiber diffuser together with the polygonal shape exhaust are making a beautiful combination that worth the admiration! Yeah, more engineering porn here!
So much engineering here
