Brown is a very bright CEO. Toyota is proven time and time again as a formidable manufacturer. It would be amazing to see Toyota making it's return into F1.

It would be pretty amazing to see Toyota back on the grid along with the addition of Audi and Ford! We'd have a proper engine constructor battle going.

It seems to me this might be just a data sharing program, as to what I learned from the WEC community on reddit. McLaren used to use Toyota's wind tunnel which I think is in Cologne. McLaren might not be using that wind tunnel anymore and in return they take Rio as a reserve driver to still have some data shared between the two manufacturers.
