European Solar Challenge 2018


Circuit Zolder seen from above (imagery: Landsat, solar car photo: Bochum, chart: Scientific Gems). Sunset/sunrise and the phase of the moon are correct for the date.

The 14 teams listed below (from 12 countries, racing 17 cars, including 10 Challengers and 7 Cruisers) have registered for the 24 hour iLumen European Solar Challenge, to be held once again at Circuit Zolder (Belgium) on September 19 to 23. Results from 2016 are here, the current regulations are here (6 m2 panels are allowed, as is night-time external charging), and the programme for this year is below (overlaid with a recent weather forecast). The 24 hour track race starts at 13:00 on the 22nd, with sunset at 19:37 that evening and sunrise at 07:26 the next morning, and with the race continuing until 13:00 on the 23rd.

Teams are listed on this page by team number. See also the official iESC social media at     (click on the symbols) and the live KO Chicane results for Friday.


Scoring for the iESC this year is 50% based on the number of laps completed, and 50% based on five other criteria. The “regularity test” for consistency of speed is new (and I don’t quite see the point of it). The “safety challenge” is apparently a simulated emergency (and will be good practice for the WSC).

This team came 2nd in the WSC 2013 Cruiser class. They came 3rd in the WSC 2015 Cruiser class. They came 2nd in the WSC 2017 Cruiser class.
