The McLaren P1 is an insanely clever beast on the road! The way the air moves over the car and creates down force is absurd. The aerodynamics of the car itself create more down force than the weight of the actual car. The rear wing has to retract when it hits speeds of 150 MPH to prevent that down force from crushing the suspension!
