Neerpasch had arranged the sale of Rosche's M12/13 engine to Talbot, but Rosche and Neerpasch's successor, Dieter Stappert, successfully protested to their board that such an undertaking deserved full works commitment, particularly as the fact that M12/13 was derived from a production road car engine meant that potential success could be extremely valuable to BMW from a marketing and sales point of view.
Neerpasch arranxara a venda do motor M12/13 a Rosche a Talbot, pero Rosche e sucesor de Neerpasch, Dieter Stappert, protestou con éxito ao seu consello de que tal empresa merecía o compromiso cun equipo oficial, sobre todo polo feito de que o M12/13 era derivado dun motor de coche de estrada de produción, o que significaba que o éxito potencial podería ser moi valioso para BMW desde o punto de vista de mercadotecnia e vendas.
