What is unique about the aerodynamic design of the McLaren W1?

The McLaren W1 is only the second road-legal car to use "ground effect" aerodynamics. In 'Race Mode', the car lowers, and the active front splitter and the 'McLaren Active Long Tail' rear wing deploy. This rear wing extends backwards by 300mm, and its angle is adjusted by four electric motors, generating a staggering 1,000 kg of downforce.

McLaren W1 係史上第二款合法街車用上「地面效應」技術。當佢進入「Race Mode」時，車身高度會降低，頭泵把嘅主動式翼片同車尾嘅「McLaren Active Long Tail」主動式長尾翼就會展開。呢個尾翼可以向後延伸 300mm，並透過 4 個摩打調整角度，產生高達 1,000 kg 嘅驚人下壓力。
