I talked with a aerodynamic engeneering, and he is working in a new shell desigh, that according hin will be much more stable and quite more efficient than Morelli shape.
He told me it will have more than 50% laminar airflow on surface.
Just to remamber about laminar airflow, that it it's not all the air following the countorns, but a bit more difficult than that :
So, I wonder if it with wheels will got 0,09 or 0,08.
