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

Austria Notables

• Barrichello: with everything that happened last weekend, one important fact slipped by everyone's attention, and we're here to rectify that. Rubens Barrichello's pole position in Austria was the fifth of his career, but it was also the first time the Brazilian took pole in dry conditions - all previous four were attained in rain or quickly-changing dry/wet track.

• Setting the Record Straight: Austria was the best ever qualifying result for Nick Heidfeld (5th), Felipe Massa (7th), Enrique Bernoldi (12th) and Allan McNish (14th).

• The excuses: Both Juan Pablo Montoya and Jarno Trulli had to use their spare car.

• Changes since Spain: None.
