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 in two back-to-back sessions, 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 charts and several observations, it's time to see who's hot and who's not...

With twelve double qualifying sessions completed for 2004, the differentials are once again on a roll! Let's see which drivers deserve bragging rights.

Germany Notables

• Antonio Pizzonia Despite the German Grand Prix being Antonio Pizzonia's first qualifying in what one might consider a top team, the Brazilian did not in fact better or match his best grid position to date - eighth in the 2003 Austrian Grand Prix.

• Changes Since Britain: Fernando Alonso is now faster than Renault teammate Jarno Trulli in the overal differentials for the second session.
