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

San Marino Notables

• Setting the Record Straight: the San Marino Grand Prix was Minardi's Justin Wilson's best qualifying position thus far (18th), while Jaguar's Antonio Pizzonia equalled his previous best (15th).

• Going Down! Looking at the averages of both Friday and Saturday, it now emerges that Michael Schumacher, David Coulthard, Jacques Villeneuve and Nick Heidfeld perform better than their teammate on Saturday but not on Friday. Furthermore, on average more drivers perform worse on Saturday than on friday - most likely because of the difference in fuel loads.

The Elevator

We've decided to also keep track of the position changes between Friday and Saturday. We're not yet sure if it means anything, but we'll keep an eye on the results for the time being...
