A recent study from Forbes has shown the average spend to win a championship in Formula 1, and it has shown the average expenses of Mercedes in the past five title-winning seasons have been over £400 million or $500 million.
The study has revealed the cost of winning championships in the past decade has increased exponentially. In 2009, when Red Bull developed its first title-winning car for 2010, the budget was as 'little' as £156.9 million ($206.7 million), but the last title-winning Mercedes car, the W09 in 2018, cost £320.6 million to develop ($422.3 million).
However, these costs don't include the development of an engine, which is a massive expense for Mercedes. If you add those costs to the total bill for the Silver Arrows, the average cost of developing a title-winning car for the Germans has been over £400 million or $500 million.
Should Mercedes win the title yet again this season, for the sixth consecutive season, the total spend will be well over £2.5 billion, or $3.5 billion. It will be a record, though, in terms of most titles in a row.
