2002 saw Frentzen drive for the Arrows team. He scored points on two occasions and outpaced both the Jaguars who ran the same engine. But the team went bankrupt in August and Frentzen was released from his contract. Back with Sauber for 2003, after a one-off drive replacing Felipe Massa at the 2002 United States Grand Prix, Frentzen was evenly matched with his highly rated teammate Nick Heidfeld and scored a podium finish in the penultimate race of the year in the United States.
