The bottom 6 teams in the 2005 Constructors' Championship and Super Aguri were entitled to run a third car in free practice on Friday.

The teams (also known as Constructors) were Renault, McLaren, Ferrari, Toyota, Williams, Honda, Red Bull, BMW Sauber, MF1, Toro Rosso and Super Aguri.

Renault and Fernando Alonso had so far won the majority of the races, including victory in the preceding Canadian Grand Prix.

Massa, Jenson Button, Ralf Schumacher and David Coulthard had achieved third place podium finishes.

[3] Michael Schumacher and Felipe Massa earned Ferrari a front row lockout, ahead of Giancarlo Fisichella and Rubens Barrichello.

Nico Rosberg was penalised for ignoring a signal during the qualification session, requiring him to get his car weighed at the FIA garage.

After that, the order stayed the same at the front, the only action being a battle at the back between David Coulthard, Nico Rosberg, and Vitantonio Liuzzi.

Rosberg lost out and was the only finishing driver not to score in the race, with Liuzzi gaining Toro Rosso's first ever point.
