In 1997, Trulli made his debut in Formula One with Minardi. After 7 races he replaced the injured Olivier Panis at Prost and impressed immediately, finishing fourth in Germany and even leading in Austria, looking set to finish second until his engine blew. He stayed at the Prost team for the next two seasons and eventually scored his first podium in wet conditions at the 1999 European Grand Prix. However, this was a rare highlight in a race few of the main front-runners finished, and the poor performance of the Prost team convinced him that a switch to Jordan would bring improved results.
