The second edition of the revived Desafío Ruta 40 will have a triple-digit grid in Argentina as 29 FIA cars, 54 FIM bikes and quads, 17 Open teams, and 15 Desafío Ansenuza navigation-based competitors take the stage.
Nasser Al-Attiyah will seek to defend his 2023 win as one of nine Ultimate entries. Every entrant is a T1+ regulation car, all the big three of Toyota, Prodrive, or Mini.
Conversely, Mitch Guthrie is not entered in Challenger, meaning the class will see a new winner with Rokas Baciuška headlining the twelve. Nicolás Cavigliasso, set to overtake the absent Austin Jones for second in points, hopes to close the World Rally-Raid Championship gap to Baciuška at his home event.
Ricardo Ramilo was the highest finishing W2RC driver in SSV at the 2023 edition and hopes to do the same among the seven.
Eleven bikes comprise RallyGP as full-timers Hero MotoSports and Monster Energy Honda Rally Team finally have more company, with two of Pierer Mobility Group’s W2RC marques GasGas and Husqvarna set to return led by reigning champion Luciano Benavides; the two brands have not appeared in the series since the season-opening Dakar Rally in January. His brother Kevin would have represented KTM in Argentina but got hurt while training in early May. Besides their usual duo of Ross Branch and Sebastian Bühler, Hero has added José Ignacio Cornejo to their roster; the team will also make their début in Rally2 with new test rider Ramiro Barco Oliva.
Rally2’s Michael Docherty will also sit out the race with injury. Romain Dumontier and Bradley Cox are separated by just three points in the class standings while Konrad Dąbrowski is breathing down their necks, eleven points back. Twenty-two bikes are in the category for Argentina.
Three riders make up Rally3.
The Quads, still reeling from their exclusion from the 2025 Dakar Rally, will once again have the highest turnout of the season as South America comes out swinging with seventeen riders led by their Argentina compatriot and Dakar winner Manuel Andújar.
The race runs on 1–7 June.
