About the marque

Founded: 1950 – 1991
Country: France

Garage owner and amateur racer Henri Julien began building JH-series 500 cc cars in 1950, with Christian Vanderpleyn later turning the small Gonfaron operation into Automobiles Gonfaronnaises Sportives. From 1970 AGS progressed through Formule France and Renault, Formula Three and European Formula Renault into Formula Two, where Philippe Streiff won the category's final race in the JH19C. Formula 3000 JH20s preceded a remarkably ambitious Formula One entry in 1986. Despite two championship points and thirty-one distinct JH designs or evolutions through the JH27, chronic underfunding ended racing in 1991. The surviving organization became a driving school and historic-racing operation at Le Luc, revived under new ownership in 2019.
