There is a surprise at Aston Martin as Germany’s Mike Krack joins as team principal.
Krack has little modern F1 experience, but worked with Sauber for eight years during the BMW era, having started his career with the Munich firm. He rose to be chief engineer. He left F1 with BMW in 2009 and worked with Sebastian Vettel in that era. After BMW quit in 2009 he did some jobs in Formula 3 before returning to BMW as chief engineer in DTM for two years before switching to Porsche as head of track engineering with the LMP1 programme.
He returned to BMW Motorsport in 2014 in senior engineering roles and eventually was named head of BMW Motorsport in March, although the company has little left now after its fixation on electric cars filtered through the system.
It will be interesting to see how he does, dealing with a team owner who is also a racing dad, and a team that is in a state of considerable flux at the moment.
