Sauber strangely decided to take a few steps back in evolution and reverted back to the European rear wing version combined with the enlarged engine cover’s shark fin at Singapore alongside with the Spanish rear wing spec . Founding out that the older parts are better than new must really make a F1 team nervous and frustrated .
At Singapore Sauber reverted back to the Spanish wing spec with the old inner section and back to the Bahraini spec at Interlagos and Marina Bay .

Like all teams so Sauber brought a special very low downforce rear wing for Monza with single vented endplates , keeping also its F-duct system to gain extra speed at straights .
Inspired by Renault , Sauber changed completely the inner front wing section and made also the wing profiles more wavy .
The C29 exhausts of periscope style blow up and inwards ( hot emissions in red ) while under them there is also a hot air outlet to help car cooling ( hot air exit in orange ) .
At very hot conditions Sauber had the option to use gills around the exhaust bodywork .
The Canadian low downforce rear wing with the double vented endplates was brought back to use at Spa .
