The model, codenamed P14, will achieve 0-124mph in 7.8sec and a standing quarter mile in 10.3sec, according to the Woking-based firm.
McLaren also claims the new exhaust system creates a clean, crisp note to “match the extreme performance of the engine, with the further option of a sports exhaust”.
McLaren SuperSeries vehicle line director Haydn Baker said: “Power, torque and throttle response are all significantly enhanced compared to the first-gen Super Series, yet with fuel efficiency and emissions also notably improved.”
McLaren has already confirmed the car will get a new active chassis control system as well as having major aerodynamic gains.
It will also use a new monocoque Monocage II, which employs a T-bar-shaped roof structure that allows for the extended dihedral doors, along with a wider entrance and lower sills for better access, similiar to the company’s iconic F1 road car.
