Disappointed with the Dallara 190, designer Tolentino was replaced by Nigel Cowperthwaite in for the design of the 191, and the team's Ford Cosworth engines were replaced by new Judd V10s. De Cesaris also needed replacing, as he had signed to drive for the brand new Jordan team. Finn Jyrki Järvilehto, otherwise known as JJ Lehto, was signed and quickly gained BMS Scuderia Italia their first points since 1989, earning a third-place finish at the San Marino Grand Prix. Pirro followed this with sixth place at the Monaco Grand Prix and his first point for the team. However, Lehto failed to finish more than half of the races during the year and Pirro struggled to prequalify for several races (but only in the first half of the season due to the 1990 disaster), and so the two were ranked twelfth and eighteenth respectively in the Drivers' Championship. Dallara once again earned eighth in the Constructors' Championship.
