The McLaren P1

The Mclaren P1's design is guided entirely by around aerodynamics, which is no surprise because McLaren's core competency is aerodynamics. Drawing from their F1 heritage, McLaren has fit an active rear wing that can extent up to 12" on track and 5" on the road. The pitch angle is also actively changing, hitting a maximum angle of 29 degrees. A smooth underbody is essential to creating stick-to-the-pavement suction but McLaren increased their downforce by placing a pair of flaps mounted in front of the wheels change that their angle (from 0-60 degrees) to boost downforce at the front. Not only do they increase downforce but both active aero-pieces function as air-brakes as well. In all, the P1 generates a total of 1,323 pounds of downforce (5x more than the McLaren MP4-12C) yet still produces a drag coefficient of a typical sports car (0.34).
