Tauranac left Brabham early in the 1972 season after Ecclestone changed the way the company was organised without consulting him. Ecclestone has since said "In retrospect, the relationship was never going to work", noting that "and I both take the view: 'Please be reasonable, do it my way'". The highlights of an aimless year, during which the team ran three different models, were pole position for Argentinian driver Carlos Reutemann at his home race at Buenos Aires and a victory in the non-championship Interlagos Grand Prix. For the 1973 season, Ecclestone promoted the young South African engineer Gordon Murray to chief designer and moved Herbie Blash from the Formula Two programme to become the Formula One team manager. Both would remain with the team for the next 15 years. For 1973, Murray produced the triangular cross-section BT42, with which Reutemann scored two podium finishes and finished seventh in the Drivers' Championship.
