I don't think I would take the front bracings as any sort of definitive evidence that it is I6. Both the 328 and 335 have them and I think we are pretty sure it won't be a 4 cylinder. All it means to me is that whatever engine they are using will fit in the same engine bay and it is easier to leave the front support brace bars (or whatever they are called) the same rather than re-engineering them.
