好輕。McLaren W1 嘅最輕乾重淨係得 1,399 kg。佢用咗全新嘅「McLaren Aerocell」碳纖維單體式底盤，雖然比 P1 長咗，但都保持到極輕嘅體重。呢個底盤嘅設計完全係為咗空氣動力學而服務，例如個地板係升起嘅，創造出地面效應通道，呢啲都係喺合法街車上好少見嘅設計。
It is very light. The McLaren W1 has a minimum dry weight of just 1,399 kg. It uses an all-new 'McLaren Aerocell' carbon fibre monocoque, which manages to be incredibly light despite being longer than the P1. The chassis is dictated entirely by aerodynamics, featuring raised floors to create ground effect tunnels, a design rarely seen on a road-legal car.
