A Bowers and Wilkins audio system and fixed carbon fibre racing seats are included as an option.

Alcantara and Weir leather upholstery along with carbon fibre trim is standard. The interior is designed to be a blend of modern and race-inspired elements. The same tub underpins the Senna, Speedtail and the Elva sports cars. It also reduces the size of the pillars of the roof, improving visibility for the driver. Called the MonoCage II, the tub allows for dihedral doors with large cutouts for easier entry and exit. The carbon fibre tub used in the 720S' chassis is based on the similar principle of the MonoCage unit in the P1 but is 18 kg (40 lb) lighter than its predecessor. The 720S according to McLaren is 91% new as compared to its predecessor. The 720S is the first all-new car to be introduced by McLaren as a part of its new plan to launch 15 new cars into the market by 2022. 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.

It is the second all-new car in the McLaren Super Series, replacing the 650S beginning in May 2017. The McLaren 720S is a sports car designed and manufactured by British automobile manufacturer McLaren Automotive.
