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.
