Overview
- Facundo Chapur took the victory at Autódromo Oscar Cabalén on Sunday, May 31, overtaking pole-sitter Otto Fritzler at the start and holding the lead to the flag.
- Otto Fritzler finished second and Juan Tomás Catalán Magni was third in a final that ran without safety-car interruptions and featured few passing moves.
- José Manuel Urcera moved into the championship lead with 184.5 points while Chapur climbed from ninth to sixth with 156.5 points and secured the season win required to qualify for the Copa de Oro.
- The result highlighted changing competitive dynamics as Mercedes scored a notable podium through Fritzler and Torino used a longer rear wing that teams said affected performance balance.
