The revised infographic above shows solar car teams that are likely to be entering in the World Solar Challenge this October, with my estimate of reported current progress (on a red–amber–green scale), taking into account recent social media updates (the team list has been updated also).
Many teams are obviously working hard behind the scenes, so that the assessment here is overly pessimistic in most cases. Also, one of the factors used by the rating script is recent Twitter activity, so that there is a slight bias against teams without Twitter accounts. Still, the infographic gives some idea of team progress.
In other news, the new BWSC FAQ addresses, inter alia, the confusing (and, in my view, misguided) regulation 2.2.4.
