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

Italy Notables

• Kimi Raikkonen: The young Finn lost one grid position and 0.549 compared to teammate David Coulthard after his fastest time was removed. That played in the Scot's favour this round, although it still put Raikkonen ahead.

• Setting the Record Straight: Eddie Irvine's 5th position on the grid was the best qualifying position ever for a Jaguar driver.

• Trivia: Alex Yoong's difference to Mark Webber is bigger than the gap between 5th and 17th on the grid.

• Changes since Belgium: Jacques Villeneuve is now faster than Olivier Panis.
