TECH WEEKLY: The unique McLaren design feature that seems to have affected Norris more than Piastri
Lando Norris has mentioned how this year's McLaren does not give him the same level of confidence as last year's, and a key design feature could be the reason.
At a few of the hotter races so far this year McLaren has used a unique cockpit pre-cooling device.
It works when the chemical ingredients of dry ice are mixed in a container, placed in the car’s nose, and the resultant emissions of the cooling vapour are pumped through the car for several minutes as it sits on the grid. The container is then removed before the nose is re-assembled ready for the race.
Furthermore, the underside of the McLaren seat and the floor beneath are coated in heat-deflecting gold foil.
