The 1992 car, the Ligier JS37 seemed promising, a brand new design featuring the race-winning Renault V10 engine, but it proved to be only inconsistently competitive.

At the 1992 Belgian Grand Prix Comas was involved in a severe accident at the Blanchimont corner during Saturday qualifying.

Comas was not retained by Ligier for 1993; he instead signed with the small Larrousse team, running the LH93 chassis powered by Lamborghini V12s.

For the last race of the season in Australia, Comas relinquished his seat to make way for Jean-Denis Delétraz who brought more funding to the team.

At the 1994 San Marino Grand Prix due to a radio miscommunication Comas was released onto the track during the red flag after Senna had crashed, arriving at the Tamburello corner where he met the workers and vehicles, including an aid helicopter which had landed at the scene.

Having had to brake hard to avoid hitting either marshals, their vehicles, or the helicopter Comas declined to participate in the restart of the race, after witnessing medical staff treating the mortally-injured Senna.

Comas spent the 2004/2005 seasons with Masahiro Hasemi's privateer Hasemi Sport team, running non-factory Nissan 350Zs in GT500, including inheriting the team's only win (co-driving with Toshihiro Kaneishi) thus far, on the evening of 18 December 2004 at the "All-Star 200" exhibition race on California Speedway's combined oval/road course after the unofficial winners were penalized 60 seconds on their finishing time for a pit window infraction.

At the fifth race of the 2006 season at Sportsland SUGO, Comas was replaced by Seiji Ara due to ill health.
