Route
All the stages are located in the state of Guanajuato. Compared with the 2018 edition, the route of the 2019 edition was shorter. The Duarte — Derramadero stage was removed. Instead, the Mesa Cuata stage joined the itinerary.
The 2019 edition of Rally Mexico started with a curtailment of the opening stage due to an irreparable damaged jump. Andreas Mikkelsen took a short-lived lead on Friday morning, but the Norwegian lost his lead to Sébastien Ogier as they hit a rock and damaged the suspension. Teammate Dani Sordo also forced to retire from the day due to electrical issue. Jari-Matti Latvala was running in fourth before retiring with alternator failure. The other major retirement of the first leg was Teemu Suninen, who went off the road in his Fiesta. The young Finn retired from the rally in the end. It turned out that Ogier was a lucky man. Despite a front-left puncture, he still reduced his time loss to just twenty seconds as his teammate Esapekka Lappi went off the road and caused the red flag, which saved his rally-winning chances. However, Kris Meeke wasn't as fortunate, as he suffered a puncture on the following Otates stage, with damaged suspension, which dropped him from the lead down to fifth place. Eventually, Ogier net his fifth Mexico victory with a power stage victory, surpassed Thierry Neuville in the drivers' standings in second, narrowing to four points off the championship leader Ott Tänak, who finished second overall, with Elfyn Evans got his first podium finish of the season. The rally was not without controversy however. The damaged ramp was met with criticism, deeming it to be unnecessarily dangerous to both drivers and spectators, and allegations of cheating surfaced with Kris Meeke accusing Citroen of abusing red flag rules to give Ogier an unfair advantage; Meeke would later retract his statement in an apology.
