I’m guessing that Mclaren will also be without an S-Duct this season... It’s interesting that it has been the only team without one now for a few seasons.

The S-duct exploits a loop hole in the regulations. No holes are allowed through the cockpit or the structural part of the nose, so the ducting from bottom to top passes between where the nose cone meets/attaches to the bulk head
Because of the way McLaren house the suspension, very high-up with the hydraulics on the outside of the bulk head it prevents them from running an S-duct as there is no room for the ducting to pass
They must believe their suspension set-up bring them a bigger gain than the S-duct would as it’s been that way for 4 or 5 years
Can you think of any substantial gains which the higher mounted suspension brings, relative to the lower ones?
The transmission is reinforced where the suspension is mounted, which adds bulk and takes up space. That space takes away aero performance because the area you open up if you move the suspension up higher is right in front of the diffuser. The more air you can channel to go over the diffuser, the higher the pressure in that region, and you get a greater pressure differential from the underside of the diffuser.
