One thing that is sometimes overlooked about this season is that Mercedes were so dominant early on that they stopped developing the car and moved their focus onto developing the 2021 car. The expectation was that Red Bull, who were continuing to work on their 2020 car, would start to close the gap as the season progressed. And that's what happened.
Here's a quote from back in early October:
"We have not been making any improvements to the car for a long time," team boss Wolff is quoted by Speed Week.
"We have given it a lot of thought, because you cannot afford to prematurely end the development of the current car every season. But we have decided to focus entirely on 2021 and 2022."
In the meantime, Dr Helmet Marko says Red Bull's 2020 development is still "fully" in action, with the result that Max Verstappen was closer to the pace at the Nurburgring.
Wolff admits the "balance of power" could therefore change before the end of the season.
"We have seen a couple of times that we had a very good start to the season and also a strong middle section, and then our opponents catch up at the end," he said. "That is because they continue to develop."
