Dear PP,
a DRC suspension has never been installed within the Factory in Ingolstadt and as the RS 5 production moved to IN the needed plant additions (tools etc.) will be done during the summer break.
Pre-production cars (like the press cars) were made in small quantity and therefore passed the delay. Production will start off- and the Market introduction volume will be made without the sport suspension plus.
As you can see on the TT-RS the "base" suspension is very good and some customers prefere the regular suspension over the Sport plus version. (TT-RS magnetic ride) Same with the RS 5.
