Do you think Ferrari is using common mirrors just for the sponsor? It could have any sense?
No, with the way the mirrors are angled they simply didn’t find the ducted ones useful. They could just make the sponsor smaller...
The mirror rules are significantly more restrictive this year - the centre of the mirror face has to be in a very specific place (which is why they're all more outboard). The mirror housing is also in a much smaller volume - between 60mm of the mirror face extending forwards and 15mm of the mirror face heading backwards, and within 15mm around the perimeter of the mirror.
Perhaps they don't see any advantage to the vented design within the new restrictions.
Again the actual rules are stupidly long and restrictive.
14.3 Rear view mirrors :
14.3.1 A mirror is defined to be the assembly of a reflective surface, its housing, and mountings which connect them to the sprung part of the car. Mirrors must remain immobile in relation to the
2019 F1 Technical Regulations 69/111 05 December 2018

sprung part of the car. Mirrors should be virtually removed for all legality aspects of Article 3 to be satisfied.
14.3.2 All cars must have two mirrors mounted so that the driver has visibility to the rear and both sides of the car.
14.3.3 The reflective surface of each mirror must be a rectangle which is 150mm wide and 50mm high (+2mm/-0mm for both dimensions), with a radius no greater than 10mm applied to each corner. Non-planar mirrors are permitted provided that their reflective surface can project onto a rectangle of the dimensions specified in this Article.
14.3.4 To ensure rear visibility, the centre point of the reflective surface mirror must lie between 575mm and 700mm forward of plane C-C, between 500mm and 550mm from the car centre plane and between 640mm and 680mm above the reference plane.
14.3.5 The mirror housing must:
a. In front view, be no more than 15mm from the reflective part of the mirror at any point
b. In plan view, be no more than 15mm from the reflective surface in the rearward direction, or 60mm from the reflective surface in the forward direction, at any point, these dimensions being measured in the direction of the car centre line.
c. Not obstruct any part of the reflective surface, either towards the driver or in the rearward direction.
14.3.6 There must be no more than two mountings connecting the mirror housing to the bodywork.
a. A maximum of one mounting may connect the mirror housing to the survival cell. Such a mirror mounting must:
- Lie between two vertical lateral planes, 15mm behind and 50mm forward of the inner edge of the mirror’s reflective surface
- Lie between two horizontal planes, one 550mm above the reference plane, and one passing through the lower edge of the mirror’s reflective surface
- Lie inboard of a vertical longitudinal plane passing though the innermost point of the mirror’s reflective surface
- Form no more than a single section when intersected by any longitudinal vertical or horizontal plane
b. Any other mirror mounting must lie in its entirety between two vertical longitudinal planes which pass through the innermost and outermost point of the mirror housing, and when viewed from above must not protrude more forward than the mirror housing or more than 50mm rearward than the diagonal line defined in Article 3.5.5 (d). Furthermore, any intersection of each such mirror mounting with a vertical lateral plane must:
- Form a single section
- Be no more than 50mm high or 10mm wide
- Lie between 550mm above the reference plane and 40mm below the centre point of the mirror’s reflective surface.
14.3.7 Teams will be required on request to supply the FIA with CAD data with regard to the visibility of their mirror arrangement, and the FIA will retain the right to modify the dimensions in Article 14.3
