From the Spanish Grand Prix, the car ran with higher cockpit sides after Wendlinger suffered severe injuries in a side-on accident during qualifying at the Monaco Grand Prix which left him in a coma. Higher cockpit sides were later made mandatory for all cars in the 1996 season, and were still in use up to 2017, when they were integrated with the "halo" system.
The C13 raced with Broker as main title sponsor until the 1994 French Grand Prix, when Tissot replaced them on the car.
The C13 was replaced for the 1995 season by the Sauber C14.
