I don't know if they do but they are definitely aware of it. With performance I meant both athletic and cognitive performance. I would even say the link between circadian rhythm and cognitive performance is much more obvious than with physical performance. E.g. car accidents peak at the circadian low, alertness moves in parallel with the circadian rhythm etc. I don't know anyone in particular from the racing team I'm afraid. Being the fantastic engineers that they are, they did a lot of work around optimising human performance (they were very secretive with specifics, this was one of the few concrete examples). At the time they had a team that tried to package some of this know-how into products/services and bring to market. I was working in employee health which was one of their target areas.
