TECH WEEKLY: The unique McLaren design feature that seems to have affected Lando Norris more than Oscar Piastri

At a number of of the warmer races to date this yr McLaren has used a singular cockpit pre-cooling system.

It really works when the chemical components of dry ice are combined in a container, positioned within the automobile’s nostril, and the resultant emissions of the cooling vapour are pumped via the automobile for a number of minutes because it sits on the grid. The container is then eliminated earlier than the nostril is re-assembled prepared for the race.

Moreover, the underside of the McLaren seat and the ground beneath are coated in heat-deflecting gold foil.
