2021 marks the introduction of Formula One's budget cap, and the bigger teams in particular are having some trouble not exceeding it.

Christian Horner calls it a 'huge challenge' to meet the budget cap.
Formula 1 wants to become more sustainable, and to achieve that it has to make some serious cuts. This year there is a limit of $145 million, and that limit will be lowered to $135 million the next two years. For the smaller teams this is an advantage rather than a disadvantage, but the big teams have to be creative.
