I updated my previous post to include visualisations of the official results of the iLumen European Solar Challenge. However, a helpful commenter shared a link to the detailed lap data, so above and below is some further analysis on lap times. Colours are the same as in the previous charts. As always, click to zoom.
The chart at the top shows pit time (including recharging time) as almost-horizontal lines, and pit time is also visible as gaps in the chart below. The histograms show that Top Dutch (6), the two cars from Sonnenwagen Aachen (7 and 70), Istanbul Technical University (34), and the experienced drivers in BOSolarCar e.V. (11) were particularly good at driving consistent lap times.
Measured by median lap times, Stella Vita from Eindhoven (41), Covestro Photon from Aachen (7), SunRiser from Bochum (11), RED E from Twente (42), and BluePoint from Agoria (8) were the fastest cars.
