A new BMW brake pad package shows the appearance of a new model - “M550dX”. This new F10 model could feature the long rumored tri-turbo diesel engine. According to Scott26 (quoted below), it’s going to be an all new engine and will be available on all BMW models in the upper segments by next year.
It’s not an F10 M5 with a diesel motor as some claim, but will be a stand-alone F10 model like the M5 (maybe with M badge?). It will have its own look with a specific aerodynamic kit.
