After four seasons in Formula 1, the start of a new decade gave AGS reasons for hope. The new headquarters at Circuit du Var had been completed and the team moved in over the off-season, finally abandoning the tin shack of the true “garagiste” days. Cyril de Rouvre reshuffled the administrative staff. He appointed Hugues de Chaunac, founder of the multi-disciplinary ORECA racing team, to be the new Technical Director, relegating Henri Julien further to consultant level. In addition, late in the 1989 season, Michel Costa had decided that his move to Coloni had been a mistake, and he returned to AGS to be put in charge of designing an all-new car for the upcoming year. Both drivers Gabriele Tarquini and Yannick Dalmas stayed on for another year. Costa’s new creation JH25 was not ready for the start of the season, so AGS started the year with the JH24, given a few minor modifications but not enough to be officially designated a “B” specification. The JH24 was used in three first races of the season. The car was now painted in an all-black livery with the yellow logo of French fashion designer Ted Lapidus.
The new JH25 car appeared only for Monaco GP, fourth race of the season. While the car was also completely revised aerodynamically – with lower sidepods containing a revised cooling system – compared to the JH24, most mechanical components, including the 6-speed longitudinal gearbox and the engine were carried over from previous cars. Both drivers, Tarquini and Dalmas, managed to succeed pre-qualifying 4 times each during the season’s 16 Grand Prix, but the car only made it to the finish on 3 occasions. The best result was a 9th place finish for Dalmas at the Spanish GP.
