The floor and footwell of the W1 are positioned higher than those of the P1, modifying airflow beneath the car. The active aerodynamics system has been updated, with the rear wing controlled by electric motors. The wing can raise, lower, and rotate, functioning as both a
downforce aid and an
air brake while also incorporating a
DRS mode. The W1's cooling system is structured to manage
thermal loads, particularly in high-performance driving conditions. It incorporates three separate water-glycol circuits, each operating at different temperatures: • A high-temperature circuit with four
radiators for engine cooling. • A low-temperature circuit for charge cooling. • A dedicated hybrid cooling circuit for the
E-module, battery, charger, and
DC/DC converter. A total of 10
heat exchangers are included to manage general cooling needs, including
HVAC and oil cooling. The W1 features an eight-speed
dual-clutch transmission (DCT) designed to handle high
torque levels. A
hydraulic E-differential determines the torque split between the rear wheels,
enhancing mid-corner traction. The W1's E-module contributes up to and is mounted beside the transmission. It features: • A battery designed for rapid power delivery. • Active aero stemming from multiple downforce controls using the spoiler and front bumper. • Second-generation
dielectric immersion cooling for effective thermal management. • Onboard charging capability, allowing the battery to be replenished to 80% in 22 minutes. • McLaren’s Active Long Tail Rear Wing, providing multiple modes of downforce. The W1 incorporates
ground-effect aerodynamics, including an underbody that enhances airflow and downforce, drawing influence from the
McLaren Formula 1 Team's engineering, and active aerodynamic elements, including an adjustable front
splitter and rear wing. Internal
wind tunnel tests verify that the W1 has a maximum total downforce of . ==References==
