Mercedes' technical director revealed the team was anxious over lost performance from last year. It remains to be seen if they have done enough to recover from the minor regulation changes.
Speaking at the launch of Mercedes' 2021 challenger at the team base in Brackley, Allison said:
"We feel utterly excited about what's in front of us but equally anxious because so much has changed in these regulations at a detailed level that does really punish the car from a performance point of view."
"Have we done enough to recover back that performance better than our competitors? None of know and yet we know we really care about it and so the anxiety is quite high this year."
Mercedes are favorites at the start of the season
Mercedes held a distinct advantage in 2020 with a faster car than the entire grid. Lewis Hamilton coasted to his seventh world title while Mercedes won their seventh consecutive title since 2014.
The cars remain similar to last year. Teams were allowed to make limited changes to their contenders, which ensures that no team makes gigantic leaps in performance. This makes Mercedes favorite for the title this season.
