Results of the ASC 2022 Road Race

Wrapping up the American Solar Challenge, the chart above shows the final official distances. The chart places optional “loops” driven at the end of each stage, even mid-stage loops. At the bottom of each bar is the final placing, with a star marking MOV (Cruiser) cars. The notation “(Tr)” identifies cars that trailered or were deemed to have trailered.

Below is a logarithmic visualisation of the MOV (Cruiser) scoring. The final score (last bar in each group) is the product (visually, the sum, since the chart uses logarithms) of seven factors:

• The distance driven d (in miles)
• The distance driven with penalties d’ (in miles)
• The average number of people p in the car
• The reciprocal of the total external energy usage E (in kWh)
• The practicality score P (out of 100)
• The speed derating T (1/70.86 = 0.014 for AppState)
• In grey, the reciprocal h of 171,780 (the longest distance driven, times 100)

This is equivalent to the way that the scores are broken down officially (since C = d’/1717.8 and D = d×p).

The final score for AppState is 1/4.2 = 0.24, as in the official results. Esteban (Poly Montreal) achieved the highest score through low total external energy usage, but was demoted to third place after missing a turnoff early in the race, which prompted this retrospective modification to regulation 12.11.C:

“Any team leaving the tour route must rejoin the route at the same intersection where they left the route or they will be considered to have trailered from their last completed route step before going off route. Their Load On Trailer Time will be the time that they went off route.”

PrISUm (Iowa State University) was forced to withdraw early on due to electrical issues, so scores 4th in the MOV (Cruiser) class.

Challenges in the ASC 2022 Road Race

True to the name, there have been some challenges in the American Solar Challenge now taking place. On the first stage, Esteban (Poly Montreal) missed a turnoff, prompting this modification to regulation 12.11.C:

“Any team leaving the tour route must rejoin the route at the same intersection where they left the route or they will be considered to have trailered from their last completed route step before going off route. Their Load On Trailer Time will be the time that they went off route.”

PrISUm (Iowa State University) was forced to withdraw early on due to electrical issues

“Unfortunately things did no go as planned for PrISUm. Due to safety concerns for both the car and our team, we did not want to drive the car any farther. It is unfortunate that there was an electrical issue, which is hard to quickly and safely fix on race. We are very proud of our team performance at FSGP, compared to the last couple of years. Thank you to everyone for all of your support and following us throughout our journey.”

“On our 2nd loop in the city of Casper, our topshell detached from the vehicle; no injuries. The damage from this incident to the vehicle is not minor, but we worked very hard to get it back on the road! Thank you to all who helped!

Solar panels replaced, topshell corner redone in carbon fiber wet layup, tightened security attachments, lights picked up, stronger canopy, MPPTs repaired and even two flat tires all under 24h our convoy made it to time at stagepoint #2 in Lander, Wyoming just minutes from closing! The vehicle is in shape, today we are driving to Montpellier, Idaho.”

Illini (University of Illinois) had a narrow miss on the same stage:

“Today on our way to Lander, the team and Brizo faced a very near collision. As the convoy was waiting to turn left along the route, a semi lost control and tried to swerve around a pickup in front. The semi crashed a few feet from Brizo and the pickup truck landed mere inches from our chase car. Thankfully the entire team and Brizo were unharmed. However due to lost time, we had to trailer part of the second stage. Tonight we arrived in Lander and are ready for the rest of the American Solar Challenge.”

Official times for the first two stages are summarised in the chart below. The chart places optional “loops” driven at the end of each stage, even mid-stage loops. MIT leads the SOV/Challenger class, followed by Principia and Kentucky. The MOV/Cruiser scoring system is more complex, and only distances are shown here. However, Minnesota does appear to be ahead.

Latest news had most solar cars arriving at the Montpelier, Idaho checkpoint (including AppState and, I believe, Berkeley):
