Makes more sense to use sharing platform. Exora platform might have some limitations to span into D segment.

As for the engine, what we know so far its going to be the new version of E01 engine dubbed NE01.

No information weather its NA or turbocharged, although some reports the petronas engine comes with both.

Also, Proton have new engine on their own dubbed NFE. This have very little information. Rumors this is small engine, going to be use in GSC.

How come Proton owner know their 1.6NA consume like NA FC? I thought most proton kenot afford big car?
