The JH23 proved to be a good car for the small French team, in only their second full season in Formula One.

The car managed to qualify for all 16 races including 12th at Monaco, and 10th in Canada where before retiring with suspension failure on lap 41, it was only the power of the Honda V6 turbo in Nelson Piquet's ill-handling Lotus 100T that kept Streiff from passing the reigning World Champion for 4th place.

The season got off to a tragic start as Streiff was seriously injured in a pre-season testing crash at the Jacarepaguá circuit in Brazil.

Italian Gabriele Tarquini took over from Streiff and had a good season, the highlight being a 6th place in Mexico.

Three JH23 chassis were built, two are still owned by AGS and the other is on display at the Lohéac Automobile Museum.
