The chart above shows 2017 team composition for the Eindhoven and Bochum solar car teams (divided by study major, not team responsibility). Not surprisingly, electrical and mechanical engineering students are the core of both teams (about half in each case) Yet there is also considerable diversity, because the business side of a solar car team requires other skills too. The Bochum team also includes a media unit, which explains the large “other” category (one of the team photographers is a biology student, for example).
The chart was constructed by parsing web pages, which may have introduced errors (also, I guessed a bit with the German words). But the main point stands – solar car teams require a diverse set of skills.

The extensive solar car coverage on this blog is now over (until the next race). Back to ordinary science coverage now…
Based on the official results, the chart below (click to zoom) shows the final scores for the WSC Cruiser class. Each team has three coloured bars: first the number of person-kilometres, which should be large (black icons show occupied seats and white icons empty seats), then the energy usage, which should be small (number of charges, which is 6 in each case, times battery capacity), and finally the overall efficiency score, which should be large again (it is the ratio of those first two numbers). The rule for the efficiency score bar is: first bar divided by second bar, then scale so that the largest result is 80%. The scaled practicality scores out of 20 (grey bars) are then added. Eindhoven is the clear winner, with Bochum second.
The chart below (click to zoom) shows the raw practicality scores for all Cruisers (finishing, non-finishing, and non-starting).
Nuna9, the car from Nuon Solar Team
It has been my tradition to hand out “Gem Awards” after major solar car races. This WSC, the “Faster Than Lightning” gem again goes to Nuon Solar Team, the undefeated Challenger champions.

Stella Vie, the car from Solar Team Eindhoven
The “Solar Family Car” gem again goes to Solar Team Eindhoven. They completely dominated the Cruiser class.

Western Sydney Solar Team
The “Solar Car Family” gems go to Western Sydney Solar Team, for the way that they welcomed international teams passing through Sydney. Western Sydney Solar Team are, of course, also Australian champions in the Challenger class.

The chart below (click to zoom) shows the current state of play for the WSC Cruiser class, using data from the official website (although it seems to me that there are some roundoff errors in those numbers). Each team has three coloured bars: first the number of person-kilometres (black icons show occupied seats and white icons empty seats), then the energy usage (number of charges, which is 1, times battery capacity), and finally the overall score (which is the ratio of those two numbers). The black number in the final bar shows the ranking. All bars are scaled to a percentage of the maximum. It can be seen that Eindhoven has a solid lead (and they will display their own performance in detail here).
This updated table shows the 35 (out of 42) cars in the World Solar Challenge which have been spotted on the track or on the road as at 20:40 on Wed, Oct 4 (Darwin time). There are links to photos and to team social media. The third column of the table shows the car class (or, for Cruisers, the number of seats). For more detailed information about the teams, see my annotated teams list.
