FSRA 2021 vehicle

The 2021 season was very challenging, and we successfully overcame the impact of the coronavirus pandemic. We qualified for three competitions: Austria, Hungary and Croatia. In Croatia we took 2nd place in the Cost and Manufacturing event, while in Hungary we finished 10th out of 30 teams in the static Business Plan Presentation event. The students worked hard, putting in as many as 90,000 working hours over the past season, which made these results and the car’s improvements possible. Alongside the combustion (C) car, the students also developed Road Arrow’s first electric (E) project in parallel. This was the last season in which the team built a car with an internal combustion engine. FSRA 2021 will always hold a special place in the team’s history!
