On Day3 of today’s Mugello test, Ferrari appeared with a major update to their sidepodexhaust configuration. Although at this stage it’s not clear if this set up is Ferraris definitive exhaust solution going forwards, or merely another interim set up.
What’s clear is Ferrari continue to follow their own path for exhaust and cooling flow. With the main cooling outlets being via chimneys exiting from the flank of the sidepod, a solution popularly termed the “Acer ducts”, due to the presence of the sponsor’s logo on the launch spec bodywork. With the launch car the exhaust exited through the rear exit of the ducts, and latterly the exhaust was moved to prevent overheating rear tyres and the duct cut away to allow more inboard location of the exhausts tailpipe.
Now the “Acer” ducts are brought more inwards and the exhaust exits over the top of the duct, periscope style. This suggests the exhaust is not being aimed at the floor at all, simply along the centre of the top bodywork towards the beam wing and the winglet mounted atop it. This would be less effective at creating downforce, but would be less sensitive to throttle position and have less of an effect on the rear tyre temperatures.
The floor and top body mouldings appear to new and quite large sections. This also suggests that the bodywork is going to change. Often with interim bodywork the panels are smaller to allow different shaped sections to be added. However the black heat shield panel around the exhaust is removable and may allow a switch to a McLaren style open-topped duct exit.
The continued presence of the vortex generator near the mirrors suggests some downwash effect is still being created, although the current spec is not really making use of it.
I will update this post as the test develops
