Everything about the appearance of the Ferrari F138 screams 'CFD' (computational fluid dynamics), which is how all the aerodynamic surfaces of F1 cars are designed now. CFD incorporates a virtual, in-computer wind-tunnel as part of the program, itself created from empirical data collected from actual wind-tunnel testing and correlated into useful formulae over many years. Different CFD programs produce interestingly different results, and the prototype shapes are verified in full-scale, real-time wind-tunnels. Ferrari was getting inconsistent data from its own wind-tunnel during development of this design, and has shut it down for upgrades. Ferrari development is currently working to get consistant, repeatable test data from testing in a borrowed wind-tunnel facility (Toyota's)
All the explanation in the world doesn't make it any less ug-lee!
