It's no surprise MCL suddenly got 1 huge undercut. Their cockpit is very backwards like RB, & the inlet very forward > a lot of space
& now they moved the sidepods inboard systems to the fat bib storage space (blue), like RB & others, & moved the bottom SIS from sidepod to floor.
Last year they stuffed all that electronic stuff in the sidepods in order to have that ultra thin bib etc... and put the cooling system very forward to have small pods...
MCL made some similar baseline choices as RB, but they exploited them differently & less extremely in '22.
But it remains to be seen whether they replaced their twin air-air intercoolers with a smaller engine mounted air-to water one to gain extra sidepod room
