'V' is a convention created by Baron Reinhard von Koenig-Fachsenfeld which shows up in his 1951 book, 'Aerodynamiks des Kraftfahrzeugs', covering his research at the FKFS, and Braunschweig Technical University, up to the beginning of WW-II
This value is an important component of dimensional analysis, used to 'steer' research.
