For solar-car teams, the iLumen European Solar Challenge (iESC) is open for early-bird registration for the race on September 18–20 this year (with discounts for registrations before 1 Feb). Details on the event blog, and registration info here.
My reports on the 2018 event are report 1, report 2, and report 3, and 2018 teams are listed here.
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.*

*: not everything.
Below is my personal world ranking of the top 21 Challenger-class solar car teams (revised with new data from an earlier list). It was produced entirely algorithmically by using linear regression on historical data to build mappings between WSC rankings and those of other races, and then applying those mappings to the results of four recent events (WSC 17, ASC 18, ESC 18, and Sasol 18). For example, this is the mapping between Sasol placings and WSC placings. It was used to map all Sasol 18 teams to expected WSC placings:
There is as yet insufficient data to rate Cruiser-class teams (apart from the actual WSC 17 results: 1 Eindhoven, 2 Bochum, 3 Arrow). But here is the table of Challengers:

Note that Cruiser teams like Eindhoven, Bochum, and Arrow are excluded from the list. The letter P marks cars that participated in WSC 17, but did not finish, and thus were not ranked at the time. It must also be said that Western Sydney, Eclipse, Esteban, and MIT should probably be ranked higher than they are here – the algorithm is not taking into account the dramatic improvement in ASC teams this year. However, good ESC and Sasol performance has bumped up Aachen, SER, Eco Solar Breizh, and South Africa’s new champion team, TUT.
Detailed results for the recent iLumen European Solar Challenge (iESC) have just been released. The two charts above (for Challengers) and below (for Cruisers) visualise the results. The “Total” bar on the left in each case is the sum of the other bars, which reflect points for the various sub-challenges. In the Challenger class:
In the Cruiser class:
See here for more information on the teams. Well done to everybody for coping so well with the terrible weather!
Update: And don’t forget to watch the great series of videos from Bochum.
The iLumen European Solar Challenge (iESC) in Belgium has just finished, under extremely wet conditions. Lap counts are shown below. Twente clocked up about 85% of the laps they did when they won in 2016. I will post about official results when they are released. However, Twente are clearly Challenger champions, while Lodz Solar Team has won the Cruiser class on points.
The iLumen European Solar Challenge (iESC) in Belgium has held the KO Chicane component of the event, under extremely wet conditions (see this!).
This component of iESC counts for 20% of final points. On mean times, Cruisers were 2.1 seconds faster in the Chicane than Challengers. The revised chart below (click to zoom) reflects the scoring (which, it must be said, has Bochum bringing home the bacon so far). Times shown are the best out of qualifying, semi-final, and final times. See also this excellent video.
Tomorrow is the big race. For fans at home interested in the weather, here is a webcam nearby, looking towards the Zolder racetrack. See also my iESC teams list and information page and the live timing board.
Another quick solar car racing update. Teams have been arriving for the iLumen European Solar Challenge (iESC) in Belgium, and my iESC teams list and information page has been updated with latest news.
Scrutineering and qualification for the Sasol Solar Challenge in South Africa is complete (see my Sasol teams list and information page). Online tracking will be here. The starting grid for this race is:
