Sauber have announced that Heinz-Harald Frentzen will race in the US Grand Prix  alongside Nick Heidfeld. Frentzen will replace Felipe Massa, who received a penalty at Monza which would have moved him back ten places on the qualifying grid.

Peter Sauber said, "Heinz-Harald made a very strong impression at Silverstone. He adapted quickly to the C21 as well as to the seating position, which is only a compromise for him at this late stage.  This decision puts us in a strong position to defend our place in the Constructors' Championship."

Heinz-Harald Frentzen commented, "The test in Silverstone made it clear to me that the C21 is an excellent race car. I was able to familiarise myself with its handling as well as with the electronic systems. The seating position is still a compromise, and we will try to improve it further prior to the US Grand Prix. I'm very happy that I can drive a race for Sauber at this early stage, and I will give my utmost to support the team in its battle against very strong competitors."

Sauber recently announced that Heinz-Harald Frentzen would return to the team to drive for them in 2003.
