The AT&T Williams team would prepare for the fourth round of the 2010 Formula One season the Chinese Grand Prix, with the opening Friday practice session. The session would see Nico Hulkenberg leading team-mate Rubens Barrichello in a session that would see Nico fourteenth and Rubens sixteenth. The team would test a new front wing during the session which gave the team some positive results.

With their low positions in the times was the opening Friday practice a case of the Williams team struggling again or were they simply not looking for pace in the opening session.
