Not sure if it's been mentioned anywhere but from next season Racing Point will become the 'works' Aston Martin team. Not massively shocked as Lawrence Stroll bought them out but media have made a big deal of it.
During the BBC coverage they got an input from an engineer, I don't know what discipline, saying tha he had been involved in a project involving copying designs. They took as many photos from as many angles as possible and then ran what I think was a commercial package, and finished up with a copy that was exactly the same as the original.
So Racing Point may well have an exact copy of last year's Mercedes without Mercedes not being involved in an way.
