The car was somewhat quick and competitive at the start of the season but suffered from persistent understeer, but by the time Germany came around a newly designed rear wing had been fitted and the car became even more competitive; it was almost as quick as the Williams-Honda but not as reliable; Gerhard Berger was qualifying inside the top 3 on every race in the season from the next race in Hungary afterwards. Berger scored two victories in the F1/87, the Japanese and Australian Grand Prix, as well as taking three pole positions. The car demonstrated flashes of its potential early in the season with Alboreto for a short time leading the San Marino Grand Prix. However, reliability issues were a major concern. From the Hungarian Grand Prix onwards, Ferrari looked to have a car that was as quick as any of their rivals. Berger challenged Mansell for the lead at the Hungarian Grand Prix before being forced to retire. The Austrian also nearly won the Portuguese Grand Prix before spinning and handing McLaren's Alain Prost his record 28th Grand Prix win (where Berger admitted it was a result of worrying too much about Prost who consequently stated that he believed that Alboreto would not have made the same mistake), and the Mexican Grand Prix which he was leading before reliability issues forced him out once again.
