Here is a further update on the 51 teams (27 Challengers, 23 Cruisers, and 1 Adventure car) aiming for the 2019 Bridgestone World Solar Challenge in Australia this coming October. Many teams are busy with construction, and below is my best understanding of the current team status (it does not yet reflect the to-be-published official list of teams). A few things have changed since my last list, and I have added some pictures and corrected some errors.
Meanwhile, 25 teams – Bridger, Calgary, CalSol (1st in 2017), Esteban (3rd in 2017), Florida, Ga Tech, Illini, Illinois St, Kentucky, Mich St, Missouri S&T, NCSU, NJIT, Northwestern, Principia, PrISUm, Purdue, Rutgers, SIUE, UBC, UPRM, UT, UVA, W Mich, and Waterloo, including 1 WSC team – are preparing to attend FSGP 2019 in America this July.
Recent BWSC news is that JU Solar Team have a body, that Eindhoven have a bottom shell, that Top Dutch and CalSol also have shells, and that Bochum have clarified their plans.
In addition, on 24–25 May, the Albi Eco Race will have Bochum competing against Ardingly and several French cars (see my report on the 2018 event).

Thank you for the update, Tony!
It looks like many designs are converging again.
Of course we are all curious to see if the top teams are coming up with innovations to stay the top teams. Will Tokai go for an MJ array this time? Is Michigan after breaking the curse of 3rd now ready for the final step? Will Nuna X still be a catamaran? What has the Belgian team up their sleeve? What sleek design will Kogakuin bring this time? Will Western Sydney continue their move up? What will the teams do that are returning after skipping one or more BWSC’s?
In the Cruiser class I hope we will see more competition than last year.
I am gradually warming up for the reveals, speculations and of course the race.

Those are all very good questions, and I’ve been asking them myself.
I am a Polytech Solar Team (Russia) member, we will not participate at WSC, and we don’t design a cruiser car. Perhaps we will go to ASC 2020 with a challenger, but we are not sure yet.
I’m sorry, I must have misunderstood something on your social media. I have edited the list. It’s a pity that you won’t make it to Australia, but perhaps 2021?
