Italian Solar Challenge Results

Posted on September 30, 2022 by Tony

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:

Aachen
Bochum
Solaris
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

Update

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.

Italian Solar Challenge 2022

Posted on August 25, 2022 by Tony

Following the iLumen European Solar Challenge in Belgium will be the Italian Solar Challenge, from 25 to 30 September at the Autodromo Enzo e Dino Ferrari near Bologna. Here is a list of 5 teams from 4 countries (3 Challenger teams and 2 Cruiser teams) intending to race in this event. See also the race social media at

The ISC permits up to 6 m² solar panels in both Challenger and Cruiser classes. Detailed regulations can be found on the ISC website.

9 Onda Solare

Four-seat cruiser (Emilia 4 LT) – they won the American Solar Challenge (Cruiser class) in 2018, and they have written up their design process here, but they have since made substantial improvements to the vehicle, including to the aerodynamics, suspension, battery, and solar panels. There is also an unusual open tail.

Previously, Onda came 10^th at WSC 13; participated in the WSC 19 Cruiser class; won the ASC 18 Cruiser class; came 10^th at Abu Dhabi 15; came 6^th at iESC 16; won the iESC 21 Cruiser class; and came 2^nd in the iESC 22 Cruiser class. Their team number (9) is taken from the SS 9, the highway through Bologna, which was once the Roman Via Aemilia (hence also the name of their vehicle).
