Part of me feels sorry for Red Bull. After dominating Formula 1 for four years, it put its faith in Renault to deliver an engine that would enable it to continue fighting for wins and championships in the new 1.6-litre V6 turbocharged era. Unfortunately, the French manufacturer has failed.
The other part of me has little sympathy. It is insane that a company as successful as Red Bull has allowed a chain of events to unfold whereby less than six months before the start of next season it does not have an engine supplier and is facing the threat of extinction.
Renault is annoyed at the way it has been treated, although talks about a way forward between the two parties continue. Mercedes doesn't fancy stepping in, Ferrari has offered to help but only with a 2015-spec engine, while Honda has more pressing problems before it considers offering a supply.
