Helmut Marko has identified what Red Bull must do next season to prevent its car from becoming “unbalanced”, as the RB20 was known for doing.

To the Austrian, the team needs to find a “wider working window” for the RB21 to operate in than its predecessor was afforded.

Unbeknownst to Red Bull at the time, it was developing an increasingly small operating frame into its cars for it to properly work within, something that team principal Christian Horner said was first detected at the 2023 United States Grand Prix.

It proved to be a fatal flaw last year, with the Milton Keynes squad failing to retain the F1 constructors’ championship, falling behind McLaren and Ferrari over the course of the campaign.

“This car needs a wider working window so that it doesn’t immediately become unbalanced when there are slight temperature fluctuations or minor technical changes,” Marko wrote in his column for Speedweek.

“That’s exactly what our engineers are working on.”
