Here is a preliminary list of the 30 teams (17 Challenger/SOV cars, 13 Cruiser/MOV cars, and no grandfathered cars) from 6 countries entered in the American Solar Challenge next July. Cruisers are clearly even more popular than in the WSC. Surprisingly, given the WSC lineup, there are only four monohull Challenger cars in the ASC this year. The event is composed of:
- Fri 10 July to Mon 13 July: scrutineering/inspection of cars
- Tues 14 July to Thurs 16 July: Formula Sun Grand Prix (FSGP), a track event at Heartland Motorsports Park (Topeka, KS)
- Fri 17 July: display day at The Independence Square (Independence, MO)
- Sat 18 July to Sat 25 July: the main road race from Independence to Idaho, along this route
Below is my best understanding of the current team status, based on social media reports and the official list of teams. Regular attendees SIUE, Florida, and UT are missing in action this year, as are WSC stalwarts Blue Sky. In addition, sadly, Michigan, Bridger, USC, and KU have dropped out.
Teams are sorted in team number order and, as always, you can click the social media links, and click images to zoom. Currently, however, several photographs reflect old cars. My blog coverage of the event is using this tag, and you can also check out the official ASC social media at (click on the icons).
Symmetric challenger (Gato del Sol VI) – they will be back again, after doing well at FSGP 19.
Asymmetric challenger (new car: Nimbus) – they have said goodbye to Flux, and have built a new car.
Asymmetric challenger (new car: Nuna Phoenix) – these are the champions formerly known as Nuon. Since their Nuna X was destroyed at WSC 19, they are building a new car specifically for ASC, incorporating features such as a metal roll cage (pictures shown are of their 2015 and 2017 cars, Nuna 8 and Nuna 9). They have also temporarily switched from their usual number 3.
Four-seat cruiser (new car: Eliana) – the new car will have the suspension attached directly to a carbon fiber monocoque.
Symmetric challenger (SC7) – while a new SC8 is planned eventually, they will race the SC7 they sent to FSGP 19.
Two-seat cruiser (Aurora) – they are improving their car after having battery problems at FSGP 19.
Previously, Mich St came equal 15th at FSGP 17.
Monohull challenger (Black Mamba) – they have a unique asymmetric bullet car with glass-free single junction GaAs solar panels, which they raced at WSC 19. Sadly, they had a serious battery fire during that event (video here). They are a late addition to the ASC field. They are very far behind on compulsory ASC documentation, suggesting that they are in some degree of trouble.
Symmetric challenger (Mercury 6) – I believe that they are returning with their existing car.
Monohull challenger (new car: Brizo) – I understand that they are replacing the Argo that they raced before.
Four-seat cruiser (new car: MS XIV) – they are replacing their MS XII by a new four-seater, which they hope to unveil in April. They are proud of their design, which has a drag coefficient below 0.15. They decided not to have a car called MS XIII.
Monohull challenger (new car: Daybreak) – they are building a new car. They attended FSGP 19 as guests.
Asymmetric challenger (new car) – they are building a new car to replace Farasi.
Previously, W Mich came 7th at ASC 14; came 14th at FSGP 17; came 9th at ASC 18; and came 5th at FSGP 19. Their team number (30) is a temporary replacement for their usual number (786 – the sequence of digits for S-U-N on old phones), to recognize the 30th anniversary of the team’s first race in 1990.
Asymmetric challenger (new car: Ra XI) – it is great to see this team returning, after skipping 2018.
Previously, Principia came 17th at WSC 15; participated at WSC 17; came 5th at ASC 14; came 5th at FSGP 15; came 5th at ASC 16; came 13th at FSGP 17; came 2nd at FSGP 19; and came 6th at Abu Dhabi 15.
Previously, Minnesota came 4th in the WSC 13 Cruiser class; came 5th in the WSC 15 Cruiser class; participated in the WSC 17 Cruiser class; came 5th in the WSC 19 Cruiser class; came 2nd at ASC 14; came equal 10th at ASC 16; and came equal 2nd in the ASC 18 Cruiser class. Their team number (35) is derived from the Interstate 35 highway.

42 Missouri S&T
49 Georgia Tech
Monohull challenger (Endurance) – they raced this car at FSGP 19. It is quite narrow, at 1.25 m.
Previously, Ga Tech came 13th at FSGP 15; came 17th at FSGP 16; came 6th at FSGP 17; came 8th at ASC 18; and came 9th at FSGP 19. Their team number (49) is taken from STS-49, the maiden flight of the space shuttle Endeavour (which was the name of their first car).
Two-seat cruiser (new car: Esteban 10) – they are replacing the zippy little car they raced at ASC 18 and FSGP 19.
Previously, Esteban came 4th at ASC 14; came 2nd at FSGP 15; came equal 10th at ASC 16; came 3rd at FSGP 17; came 4th at ASC 18; and won FSGP 19. Their team number (55) is the year that Western Electric began to sell licenses for silicon PV technology.
Two-seat cruiser (Schulich Elysia) – they are the northernmost North American team. I understand that they are returning with the car that won the Cruiser class at FSGP 19. They are quite far behind on compulsory ASC documentation, suggesting that they are in some degree of trouble.
Asymmetric challenger (Arctan) – they seem to have been given Stanford’s 2015 car for FSGP 19 (where they failed scrutineering). They are very far behind on compulsory ASC documentation, suggesting that they are in some degree of trouble.
Cruiser (new team) – they planned on 3D printing the car body for their Cruiser, in spite of being advised against it. Progress on 3D printing was slow, with the first test prints only rolling off on 28 February. Berkeley (CalSol) gave them Gold Rush, a 3-wheel car from 2009. I’m not sure what they plan to do with it. They are also very far behind on compulsory ASC documentation, suggesting that they are in some degree of trouble. Their team number (77) is normally used by Toronto (Blue Sky).
Symmetric challenger (Eleos) – their car appears to be the one they began building for ASC 2018, based on the body moulds for CalSol’s Zephyr. It was still unfinished during FSGP 19.
Two-seat cruiser (new car: Apollo IX) – they have been building a new car for some time, but I haven’t seen a complete car yet.
Two-seat cruiser (new car: SunStang 2020) – they are building a new car for this event. The car uses Sunpower Maxeon Gen II monocrystalline silicon cells.
Two-seat cruiser – they failed scrutineering at FSGP 19. They are returning with the same car, which they claim is “a vehicle no one has seen before,” and are feeling very positive. This video provides more details.
Asymmetric challenger (Éclipse X.1) – they raced in Australia as number 92, finishing 2nd among North American teams.
Symmetric challenger (new team) – they appear to have gotten started by being given Poly Montreal’s Esteban 8. Their team number (616) is the telephone area code for Grand Rapids, Michigan.
Two-seat cruiser (new team) – they are making good progress on construction. This (Polish) video describes their project. They had originally hoped to race at WSC 19.
Asymmetric challenger (new car) – they will be returning with a whole new car – an asymmetric design this time.
