Speaking to guests after #AustralianGP Quali, Lawrence Stroll revealed part of the reason for AMR's pace & why LS was a little slower than FA, but much closer today
The bulged sidepods are driven by exhaust vibrations to ease boundary later build up over and the car

Boundary layer is a phenomena where there's a layer of air stuck to the car. Over long surfaces it builds up & upsets the aero.
AMR tech director Dan Fallows discovered at Red Bull, during the exhaust blown diffuser era, that vibrating the bodywork reduces this. As used on planes

So, the large sidepod flanks are built internally, to be vibrated by the exhausts, not using the exhast gasses, just their movement
The large flanks to the sidepods each house a large internal volume called the 'Resonant Tank'. This shakes the waterslide tunnel and the underfloor

FA has run this and found better aero performance, despite the vibration.
LS can't tun the RTs due to his pre-season fractures, as the vibration from the resonance may delay their healing. Thus, he's lacked a little speed to FA's car with the Resonance Tanks.

Such is the success the Spaniard has had with the tanks, the team are calling them Fernando's RTs.
But Lance ran just one tank in qualifying today. So Lance could finally have a FA RT in his car today on the 1st April...! 😉
