Italian Solar Challenge Results

Above are official lap counts (in two stints) for the recent Italian Solar Challenge at the Imola Circuit near Bologna.

Bochum reported electrical problems with their SunRiser, and did not race, although they had successfully completed a qualifying lap (both Bochum cars had driven all the way to Italy). The local Italian team had even more serious electrical problems.

According to the regulations, for the Challenger class, there should be added to the scores above:

  • 2 laps for the fastest lap during the race (Aachen gets this, with a time of 4:09.236 in the first stint, i.e. 70.9 km/h for the lap)
  • 4 laps for the pole position in the qualifications (Aachen gets this too)

Consequently, Aachen’s lap score should, I understand, be adjusted up to 95.

Update: it seems that the organisers have decided to retroactively merge the two classes. Rankings are therefore:

  1. Aachen
  2. Bochum
  3. Solaris
  4. Solis-EV

Italian Solar Challenge now on

The Italian Solar Challenge is now on at the Imola Circuit near Bologna. A calendar for the event is shown above. Further details and team social media links can be found on my annotated teams list. See also the race social media at

The start grid is shown below, courtest of team Sonnenwagen Aachen, who also have a livestream here. It seems that I was wrong in the pictures above; Aachen are racing only the three-wheel Covestro Photon. Bochum reports electrical problems with their SunRiser, which they expect to race only a few laps.
