The Brawn GP F1 story seems quite incredible in the modern era - that a brand new team could win the world title in its first year. In reality, the very fast Brawn cars were largely developed when it was part of the Honda F1 team.
Honda pulled out of F1 at the end of the 2008 season, with Ross Brawn and Nick Fry inheriting the team and set about making the most of the new engineering regulations. They were fortunate that the new Mercedes power unit dimensions weren't too different from the previous Honda setup, so they were able to adapt quickly to this otherwise major change.
They knew at pre-season testing that they had built a monster, recording lap times some two seconds faster than their nearest rival. Jensen Button took full advantage of this cars pace and won the F1 World Championship in 2009, helped by winning six of the the first seven races.
Mercedes appeared to "love this so much they bought the company" - acquiring Brawn GP in 2010 and reshaping it to become the powerhouse constructor in F1, winning every constructor title in the last eight years.
