It’s a bit of a stretch calling Appalachian State University / Sunergy (click: ) a new solar car team. Having rebuilt the shell of an old car donated by PrISUm, they first hit the American solar car scene at FSGP 2015 (where they failed scrutineering), ASC 2016 (where they came 6th), and FSGP 2017 (where they came a satisfying 2nd). But this year they did become a new team (in the Cruiser class), with their first car built from scratch, ROSE.
The Cruiser class is, in some ways, a tougher race than the Challenger class, but it’s an easier sell (to sponsors and to the general public). For example, I’m a big fan of Nuon’s beautiful and efficient Nuna 9S (the Stradivarius of solar cars), but you can’t really point to it and say “this is the future of transportation.” It’s far too cramped for that – more like an elegant mathematical proof or a work of art than like a practical vehicle. However, “the future of transportation” would be a feasible label for Cruisers like Eindhoven’s Stella Lux or Bochum’s SunRiser – so it’s not surprising that many solar car teams want to emulate those two pioneers.
The Stradivarius of solar cars, from Dutch champions Nuon, is nevertheless a little cramped (picture credit)
AppState did the right thing by attending ASC 2018, although their car had apparently not even been turned on before the race. Because of electrical problems, they did not manage to drive the entire distance – but they obtained good experience, and they know what to fix now. We can expect to see a greatly improved version of their car at the 2019 Bridgestone World Solar Challenge. Good luck, y’all!
AppState’s multi-stage path to the BWSC is a good model for other intending Cruiser class teams to follow. And with a drag coefficient of 0.17, they have not made the mistake of neglecting aerodynamics – because, in the Cruiser class, efficiency still rules.
ATN Solar Car Team (click: ) is a new Australian Cruiser-class solar car team. They are attempting something I have never seen done before – design and construction of a solar car by a team distributed across a continent. According to the initial press release:
I will be very interested to see if they can make this work and which virtual team tools and techniques they will use to do so. So far, ATN Solar Car Team has produced a number of quite different design concepts. The video below shows one of the more interesting ones, and has produced many admiring comments:
Note: Independently of this effort, the experienced Team Arrow will continue as a Cruiser-class team based in Brisbane (also associated with QUT).
Top Dutch Solar Racing (click: ) is a new solar car team sponsored by the northern (“top”) region of the Netherlands: the provinces Groningen, Friesland, and Drenthe (see topdutch.com). This is a region with a long history and a strong environmental focus (see montage above).
The team is associated with the Hanze University of Applied Sciences, the University of Groningen, the NHL Stenden University of Applied Sciences, and local high schools. They are building a Challenger-class car for the 2019 Bridgestone World Solar Challenge. Although I wasn’t aware of it at the time, they had observers at the 2017 event, so they know what they are up against. They will be joining three other teams from the Netherlands (Nuon, Twente, and the Cruiser-class team from Eindhoven), which means that, for the first time, an all-Dutch podium becomes a possibility.
Team manager Jeroen Brattinga explains the project in this (Dutch) video. They have also been driving a test chassis around for some time.

The 48 teams listed below (26 Challengers, 21 Cruisers, and 1 Adventure car) have expressed interest in the 2019 Bridgestone World Solar Challenge next October (social media links have not all been checked – some might no longer work):

It’s a common joke that engineers fix everything with duct tape. I’m happy to say that there’s no truth in that whatsoever.*
