Main points:

Key weight saving features include:

  • Body panels: 35 percent
  • Chassis:30 percent
  • Powertrain: 10 percent
  • Interior: 20 percent
  • Electrical: 5 percent

Powertrain:

  • More than 50 percent new components Power of 675PS (666bhp) at 7,100rpm and maximum torque of 700Nm (516lb ft) at 5,500-6,500rpm.
  • Lightweight materials and enhancements within the powertrain save 6kg, while a bespoke crossover titanium exhaust saves a further 1.1kg.
  • New turbochargers with a machined-from-solid compressor wheel – rather than cast – maximising airflow into the combustion chambers.
  • The turbochargers now have electronic rather than pneumatic recirculation wastegates.
  • Fuel flow is increased due to a new fuel pump.
  • A new exhaust manifold channels air out of the combustion chambers faster, improving power and throttle response.

Drivetrain:

  • Optimised throttle response and gearshifts up to twice as fast as previously offered.
  • The newly developed Ignition Cut technology is a technique adopted from Formula 1™ which sees a momentary cut of the fuel spark on gearshift.

Dynamics:

  • A new steering rack is the fastest fitted to a McLaren model to date.
  • Bespoke suspension tuning, including the use of the uprights and wishbones from the McLaren P1.
