Renault and Peugeot would produce mid-sized cars, leaving the small car market for Panhard and Simca, which would produce two and four door versions of the A.F.G. (Aluminium Français Grégoire), a radical front-wheel drive aluminium based car designed by Jean-Albert Grégoire. Matters did not work out quite as intended by the Plan. Louis Renault, accused of collaboration, had lost control of his company and died under suspicious circumstances in October 1944, and his business came under the control of well-connected Resistance veteran Pierre Lefaucheux who ignored the Pons Plan. Lefauchex went ahead with a small car that had been well advanced during the war, which emerged in 1948 as the Renault 4CV. That left Peugeot with the middle-sized cars, while Simca, located far from Paris to the west of the country and owned by a foreign company, was also able to escape the model planning of the civil servant. That left Panhard to produce the A.F.G. (Aluminium Français Grégoire) which was later rebranded as the Panhard Dyna X. Citroën used the duration of the plan to further develop the Citroën 2CV that had been started in the 1930s. It was launched in 1948. Although the larger auto-makers did not entirely follow its strictures, by the time Paul-Marie Pons left his job in November 1946, the vehicle market had been carved up in a way that clearly retained features of the Pons Plan:  The winners were clearly the big four French automakers that dominated the French auto-market in the 1950s and 1960s: Citroën, Renault, Peugeot and Simca. Panhard, which had concluded the 1930s as the producer of large stylish expensive cars, was reinvented as a volume maker of small cars with aluminium bodies. Aluminium producers had geared up to support aircraft makers who, following the outbreak of peace, were no longer supported by an insatiable demand for fighter planes. In the late 1940s aluminium was therefore available and relatively inexpensive, while the sheet steel which most automakers needed for their car bodies was in desperately short supply. Nevertheless, the Panhard Dyna was not a simple model to produce, nor indeed to maintain, and Panhard lacked the strong dealership and service network across the country that supported the big four auto-makers. In 1949, Panhard produced 4,834 passenger cars, which was no mean achievement under the circumstances, but still derisory when set against the 63,920 cars produced that year by Renault and the 49,424 by Citroën.
