This week James Allison (Technical Director, Mercedes-AMG Petronas Formula One Team) opened up on why the team fear they could trip up with the rule changes for 2021. Is it a bluff? Or perhaps an insight into mindset of a team so used to winning? Also this week, Carlos Sainz Jr said his first appearance in a Ferrari is "a day I will never forget". What did our own Jonathan Noble make of his first 100 laps in a Ferrari? And finally we hear from McLaren about how the majority of their 2021 chassis is brand new because of their move to Mercedes-Benz power. Production Director Piers Thynne told the McLaren website: "Whereas every other team will carry over most of its car from last year into this year, our switch to the Mercedes power unit means that's not the case for us. It's driven a huge amount of change and, essentially, we've been building a new car. The number of new parts on the MCL35M is about the same as when we built the MCL35."
