For the 1990 season, the team used the CG901 chassis, designed by Adrian Newey and powered by a Judd V8 engine. There was an aerodynamic issue to do with the Southampton wind tunnel, causing the team to struggle: the first six races of the year saw both Capelli and Gugelmin fail to qualify in Brazil and Mexico, while Gugelmin also missed out in Monaco and Canada. Newey was fired as a result, but not before making changes to the car which would result in a remarkable turnaround at the French Grand Prix. There, Capelli and Gugelmin qualified seventh and tenth respectively, before running first and second for much of the race, largely due to the team's decision not to pit for tyres. Gugelmin eventually retired with an engine failure, but Capelli continued to lead from Alain Prost in the Ferrari until three laps from home, when a misfire forced him to let the Frenchman past; second place was still a popular result.
