For several years now, Atlas F1 kept an eye on the battle between teammates with a simple measurement: comparing the qualifying times of each driver against his teammate's. The new qualifying format has made the comparison somewhat difficult - potentially, every driver could be running with a different fuel load. Moreover, with only one lap each, small errors could divert the results of any comparison significantly. But, we believe that over an entire season all these factors even out and the overall qualifying differentials between teammates remains the best tool to compare the natural capabilities of the drivers. So, with a few new charts and several observations - it's time to see who's hot and who's not...

With sixteen qualifying sessions completed for 2003, the differentials are once again on a roll! Let's see which drivers deserve bragging rights.

Canada Notables

• Friday the 13th! Friday's qualfying, held at extremely volatile weather conditions, won't be included in this year's Qualifying Differentials. The Friday differentials graph below is included merely to show just how big some of the gaps between teammates were. Therefore, the average friday graph is the same as the one after Monaco, and because of this there are no friday-saturday average graphs in this edition.

• Setting the Record Straight: Jos Verstappen gave Minardi their best grid position since 1999, when Marc Gene qualified 15th at the Nurburgring for the European Grand Prix.
