To be honest I still think the issue is too many chefs in the kitchen. I mean, they have an engineering, R&D, and technical director. How on earth do you differentiate their jobs?
You need one guy at the top deciding the concept, then how the guys below that work on that is a different issue. But when you have many chefs, then you have the real possibility of them not managing to find a consensus on the conceptual direction they should take, let alone a favorable outcome.
Bell is a decent TD. Costa maybe slightly less, but he’s not bad. Willis is… well… I wouldn’t call him the worst TD around, let’s leave it at that. But you almost need a dictator at the top who stamps his authority and forces the entire design team around a single concept.
With regards to the current car, I’m not too surprised it was strong at Monaco. I am somewhat surprised it went well in China however. It was always going to go well at a circuit where all the corners were short and sweet, or all the corners were smooth, flowing and fast.
Monaco has been strong for them since 2009 to be honest – they clearly have had good mechanical grip since 2009-2012. A large part of their problems with the W01-W03 has been their aerodynamics under yaw – basically the aerodynamics when the steering wheel isn’t straight, which has (again since 2010) lead to balance issues, with the car’s balance changing between entry, apex and exit. If you sorted one out you’d make the other two parts worse, etc etc.
