For the fifth year running, Atlas F1 is going to keep an eye on the battle between teammates throughout the season with a simple measurement: we compare the qualifying times of each driver against his teammate's result. After every Grand Prix, we will show how teammates have fared up against each other, and where they are overall since the beginning of the season. At the end of the season, the World Champion of Qualifying Differentials will be elected - the driver who beat his teammate by the most seconds. Only those who participate in at least 15 of the 17 rounds are eligible for the coveted crown; and for those who made the efforts and participated in all 17 races, the best and worst result will be scrapped.

With eleven qualifying sessions completed for 2002, the differentials are once again on a roll! Let's see which drivers deserve bragging rights.

France Notables

• Exclusions: The Arrows pair was excluded from this edition of Qualifying Differentials since both drivers made no effort to qualify. Likewise, the Jordan pair is excluded since Giancarlo Fisichella did not participate in qualifying due to bruises from his morning crash.

• Yoong/Webber: Just to iterate how big the gap is between the Minardi teammates - it's noteworthy that the difference between Juan Pablo Montoya's pole time and Allan McNish's 17th time is smaller than the difference between the qualifying times of Mark Webber and Alex Yoong...

• Setting the Record Straight: This was the best qualifying result for Kimi Raikkonen (fourth) and Alex Yoong (19th) - although the latter was still effectively last...

• The excuses: Pedro de la Rosa had to deal with two car failures during the session.

• Changes since Britain: None.
