Today in the World Solar Challenge, the next nine Challenger class cars (above) arrived (as always, click to zoom). These cars were (in order) Arrow (team 30, Australia), EAFIT (team 5, Columbia), Western Sydney (team 13, Australia), NWU (team 17, South Africa), Blue Sky (team 77, Canada), UKZN (team 14, South Africa), Goko High School (team 25, Japan), Jönköping University (team 46, Sweden), and Nagoya (team 47, Japan). I believe that Goko High School may be the first high school team to complete 3,022 km on solar power inside of a week.
The first two cars in the Cruiser class also arrived. Kogakuin (team 88, Japan) took out line honours, but Eindhoven (team 40, Netherlands) carried a passenger all the way. I believe that this more than nullifies Kogakuin’s speed advantage. Eindhoven is also likely to collect more “practicality points” in the judging tomorrow.
Also arriving were the first of what I’ve been calling the B race teams, EcoPhoton (team 18, Malaysia, above). These cars spent some time on a trailer, and will therefore compete on the basis of how much of the 3,022 km they were able to travel under their own steam. EcoPhoton have done very well for a new team, particularly given the bad luck they had (a serious battery fire, requiring battery replacement and bodywork repair – see this day 6 wrap by MostDece). They were followed by Cambridge (team 12, UK), who are probably ahead on the km count.
Ardingly (team 43, UK, above), another high school team, also arrived. They are in the B race of the Cruiser class, so their km count may be exceeded by one or more other Cruisers in the B race. The Ardingly students have done very well to build a working Cruiser, and their genuine enthusiasm has earned the respect of the top teams. I hope that they will all continue on to successful university studies.
At some point Siam Technology College (team 22, Thailand) arrived, although I understand that they have formally withdrawn from the race. In the Adventure class, TAFE SA (team 42, Australia) arrived as well. There are only three Adventure class cars, and all three trailered at some point.
Finally, walking back to my hotel, I spotted HK IVE (team 33, Hong Kong) on a trailer. I think they arrived too late for a formal welcome.
Above is another race chart summarising timing data that has been released (and omitting obviously wrong data), while current car positions are shown below. Tomorrow morning we should see Bochum (team 11, Germany) and Sunswift (team 75, Australia) in the Cruiser class, as well as Principia (team 32, USA) and Kanazawa (team 51, Japan) in the Challenger class. I suspect that Minnesota (team 35, USA), Anadolu (team 36, Turkey) and KUST (team 82, Korea) will be forced to trailer by the noon time limit. Other cars – 9, 80, 26, 82, 15, and 7 in the Challenger class; 28, 45, 38, and 31 in the Cruiser class; and 20 and 34 in the Adventure class – have already trailered, and are in the B race. They will no doubt attempt to clock up additional km if possible. The race is not over until Chris Selwood sings!
Scientific Gems 
Another great overview. I will get more into the graph later. It looks like there are a few teams who almost have a straight line from start to finish. Interesting to see that Kokaguin could speed up the last day where Eindhoven were driving on the edge of an empty battery in fear that Stella Lux would shut down. Eindhoven have posted a vivid report of the last day and their battle against Kokaguin who have now become their friends. According to Eindhoven Kokaguin have built up enough to lead by around 8 minutes after correction for person-kms and that the practicality test will hopefully bring them the trophy.
With all Adventure class vehicles having trailered this may well have been the last WSC to offer this opportunity for cars not meeting the Challenger and Cruiser criteria.
I suspect Eindhoven will win, but we will probably not know for certain until Sunday.
And the Adventure class will perhaps be needed again if another major rule change is introduced, since several teams will come back in 2017 with the same car they ran this year.
I would not like to see the Adventure class dropped as it gives a chance for teams like Houston and Liberty to take part. I would, however, like to see teams prevented from entering the class more than once with the same car.
