There have been lots of rumours in recent days that all is not well with the aerodynamics of the new Renault F1 car. It is always hard to judge these things at this time of year but the car was not quick in the recent test in Portugal, and Spanish newspapers are reporting that Fernando Alonso is not very happy. Thus it is interesting to note that yesterday Renault showed up at the Kemble airfield near Cirencester, where teams are able to do aerodynamic mapping work, running up and down the 6500ft runway. Normally these uncomplicated events involve just one F1 truck but yesterday Renault had five on site.

One can only wonder why.
