Teams using the engine supplied by Supertec are not very happy with the performance of the engine. The new Mecachrome engine supplied by Supertec seems to be underpowered compared to Ferrari, Mercedes, Honda and even Ford.

Supertec managing director Bruno Michel stated however: "I've never had any formal complaints, and they have no reasons to complain. We wanted a new engine that was reliable but had more performance than last year and a potential for development. We have that."

Although Williams driver Ralf Schumacher is not so sure: "We are certainly not being helped by the engine. You only have to see what the others are doing to realise how much behind we are."
