Carbon Monocoque

The MonoCage II tub: lighter, stiffer, shared across McLaren's Super Series and beyond.

The carbon fibre tub used in the 720S' chassis is based on the similar principle of the MonoCage unit in the P1 but is 40 lb lighter than its predecessor. Called the MonoCage II, the tub allows for dihedral doors with large cutouts for easier entry and exit. It also reduces the size of the pillars of the roof, improving visibility for the driver. The same tub underpins the Senna, Speedtail and the Elva sports cars.

Lore & Background

The 720S was launched at the Geneva Motor Show on 7 March 2017 and is built on a modified carbon monocoque, which is lighter and stiffer than the previous model, the 650S.

The MonoCage II tub is used in the 720S, Senna, Speedtail, and Elva. The 720S Spider uses a modified version called the Monocage II-S, which loses the spine running from front to rear and uses traditional dihedral doors.
