Gaston Juchet's interest in drawing begun when he was a boarder at the Lycée Louis-le-Grand in Paris.
[1] In 1958,[3] after his military service, he joined Renault's research and development department as an aerodynamics engineer.
[1][2] In 1975, Robert Opron took the direction of Renault Styling,[6] and Juchet was made one of his assistants along with Jacques Nocher.
[7] When Opron left the company in 1984, Juchet became again chief designer until he was replaced by Patrick le Quément in 1987.
[1][2] Juchet introduced modern methods of prototyping (UNISURF) and Computer Aided Design (CAD) in the Renault design and favoured synergies with Italian experts such as Marcello Gandini, Giorgetto Giugiaro and Sergio Coggiola and with the chief designer of American Motors (then a company associated with Renault), Dick Teague.
