Despite the lack of enthusiasm caused by the poor results achieved in the previous season, EuroBrun Racing, led by Swiss businessman Walter Brun, continued to develop its car in preparation for the 1990 season. At the head of the project remained the capable technical director George Ryton, who, starting this season, was joined by newly recruited Dutch engineer Kees Van der Grint. The few modifications made to the previous season’s car led to the creation of the EuroBrun ER189B.

In reality, the ER189B was intended to be a transitional car, pending the arrival of the new ER190, which, according to the team’s plans, was to be developed with the help of substantial funding from a generous Saudi sponsor. The project even included the use of a brand-new 3.5-liter V12 engine developed by Neotech in Austria. Unfortunately, the sudden withdrawal of the sponsor left Brun without the necessary funds to carry out the new project, and the ER190 remained on paper, never seeing the light of day. Disappointed and frustrated, Ryton left the team to join Tyrrell, leaving the ER189B as the only car available for the entire season, still equipped with the underperforming Judd EV V8 engine.

For the 1990 World Championship, the Swiss team, racing under an Italian license and based in Senago near Milan, managed to put two cars on the grid, entrusted to Brazilian driver Roberto Moreno and Italian rookie Claudio Langes. Despite the modifications and the work carried out, especially on the suspension, results continued to be in line with those of the previous season, that is to say, dismal.

The chronic lack of funds and the harsh reality of pre-qualifying did the rest, and neither driver was ever able to make it into the official qualifying sessions, except at the beginning of the season when Moreno managed a thirteenth-place finish in Phoenix, the first race of the 1990 championship, and a twenty-fourth place on the grid followed by a race retirement on Sunday during the third round at Imola.

After suffering the humiliation of an endless series of eliminations in Friday’s pre-qualifying sessions, at the end of the European season and before the costly trips to Japan and Australia, Walter Brun finally threw in the towel and withdrew his team from the championship. The financial burden of competing in Formula 1 also proved fatal for Brun Motorsport, which would go bankrupt and shut down in 1992.
