First day of what is supposed to be a three day test at Monza, in preparation for the Italian Grand Prix on 9 September. However, with rain arriving towards the end of the afternoon and more forecast for the next two days, it seems quite likely that running will be extended to include Friday.

The  main  item  on  the  Red  Bull  Racing  agenda  was  aero  work,  both  general  and Monza-specific. The original plan had not included a tyre comparison, but the threat of rain meant that Mark Webber did in fact try both types of Bridgestone Potenza dry weather  tyres.  The  morning  was  trouble  free,  but  an  electrical  failure  led  to some loss of track time in the afternoon.

Mark Webber continues at the wheel today.
