Monaghan: We can implement a couple more small new features.

      Paul Monaghan, chief engineer of Red Bull Racing, believes the team has recently been able to make gains primarily thanks to the right approach to upgrading the car as a whole, and this should not be directly linked to any particular technical novelties that appeared on the RB21 during the season.

      The team has taken a comprehensive approach aimed at making the chassis more balanced, which allowed Max Verstappen to take several wins in the autumn races starting with the Italian Grand Prix. Among other things, for the Monza round Red Bull prepared an upgraded floor, the effectiveness of which was immediately confirmed on track.

      Paul Monaghan: "I think a lot of factors came together. A lot of work has been done; it began at the very first races of the season because we were trying to make the car better. We thought we had figured out what went wrong, but it took a few more steps before we really sorted it out.

      Overall, the approach was comprehensive, and by the time we got to Monza the car was much better, but I wouldn't say that was achieved thanks to any one specific solution, a couple of set‑up tweaks or adjustments to bodywork geometry.

      Many different steps were taken, and they were done in the right order. Although perhaps we were frustrated that it all happened rather late, but that's life. I should remind you that in Silverstone we were on pole with the rear wing intended for Monza. How else could we have proved its effectiveness?"

      At almost every round except the United States Grand Prix the team introduced various upgrades, albeit differing in scale and significance. In that respect Red Bull Racing's approach differs from McLaren's policy, since the MCL39 has hardly changed since the summer.

      "Probably we can introduce one or two more small upgrades if we decide they work for us, but now they will be of that nature," Monaghan added.
