I sometimes wish they wouldn't divulge so much information. Other manufacturers are going to benefit from this knowledge. But I also understand why they would show so much - they are confident in their technology and don't think it's so easy to copy.
Watching the documentary it's evident that covid-19 delaying the season and changing the regulations had a huge impact on their championship bid. Also for those who said that Red Bull Honda didn't win on merit in 70th Anniversary race, the documentary showed that they were categorically wrong. The power unit was turned up that weekend with a brand new unit coupled with Max's decision to start on the hard compound. The documentary also highlighted the nature in which Honda participates in F1, leaves and comes back to advance knowledge in power unit technology and innovation for the purposes of applying them to their road going products. My sources from Honda continue to say that hybrid power trains won't be replaced with electric vehicles outright, and that bio fuel hybrids are here to stay.
