For the team's debut season in 1988, Mario Tolentino designed the ER188 chassis, to be powered by a normally-aspirated 3.5-litre Cosworth DFZ engine.

1987 Formula 3000 champion Stefano Modena and long-time Brun sportscar stalwart Oscar Larrauri were signed to drive.

A freak qualifying session at the opening race of the season in the United States saw Moreno start 16th on the grid and he eventually finished 13th.

The capable Brazilian qualified again in San Marino and came close on other occasions, but as Brun lost enthusiasm, the EuroBruns fell further and further away from the grid.

In 2021, Moreno claimed that the team purposely did not want to qualify for races so as not to spend funds they did not have on extra tyres and engine rebuilds, stating that the team gave him race-marked tyres to qualify on and the Judd engines went as long as four events without rebuilds.
