Both drivers returned to start and Jordan switched to works Honda engines which were already being supplied to rival team BAR after Mugen left the sport at the end of 2000. This led to a battle for the right to use the Honda engines in the long term. Frentzen was released from the team in mid-season, a series of disagreements with team boss Eddie Jordan a possible explanation. Jordan himself has said that he dropped Frentzen to bring in Takuma Sato for 2002, an attempt to satisfy Honda. Frentzen was replaced by test driver Ricardo Zonta at the German Grand Prix, but from thereafter Jean Alesi, in the final stages of his Formula One career, took the seat. Amidst all the turmoil, Trulli finished in the points four times, and the team finished 5th in the Constructors' Championship for the fifth time, ahead of rivals BAR.
