I just started in a new Automotive company and they are playing to build Zonal Ecu without Autosar.It is something like https://www.nxp.com/applications/automotive/software-defined-vehicle/automotive-zone-controller-:AUTOMOTIVE-ZONE-CONTROLLER
It looks like they never build SW for an Ecu until now.The reason they don't want to use Autosar is is because it is to expensive.
It is even possible to build an Ecu without Autosar now if you are not an OEM?It is possible I would say but the resources that you need are very very high.The route they plan to go is trying to find as many as possible open source libraries.....
