Actual technical changes cannot be seen on this teaser, but one thing is clear and that is that Mercedes will keep their word. Last year there was doubt in the media whether Mercedes would start with a black livery in 2021 or whether they would go back to the traditional silver. Mercedes said then that they intend to continue their campaign against racism with the black livery.

Niki Lauda is not forgotten
Considering this picture, it must be a very strange color palette if the car is not predominantly black. Prominently present is the red star. Mercedes have already indicated that in honor of Niki Lauda it will always be there, but it is more prominent than last year, as can be seen just behind the head of the driver.
The red of main sponsor INEOS also returns on the airbox. On the photo, it seems to be a slightly brighter shade of red than last year and it also continues downwards. Given the larger share that INEOS now has in the team, it would not be surprising that the red color is more prominent this year.
