F1's current rules have gradually led to the closest grid in history, which means a minor upgrade can make the difference between scoring points and being out in Q1. Paired with tricky ground-effect cars and limitations on spending and aerodynamic testing, it has made the margin for error in the development process even smaller, with every update carefully considered and requiring total integration of every department involved.
The same is true for the team now called Visa Cash App Racing Bulls, which has been on both sides of that tight midfield over the past 18 months. Other than taking a power unit, gearbox and suspension from big brother Red Bull Racing, Racing Bulls builds everything in-house with over 500 people at its main headquarters in Faenza and another 200 at its Milton Keynes campus. That's where the five-step journey from aero idea to running on track starts.
