The 21º Corona Rally México, the fourth round of the 2007 World Rally Championship season, took place between March 9–11 2007. The rally consisted of 20 special stages, of which five were super specials. The event was won by Citroën's Sébastien Loeb, followed by Ford drivers Marcus Grönholm and Mikko Hirvonen.

The drivers' championship leaders, Grönholm and Hirvonen, were the first drivers on road and lost time as they had to sweep the loose gravel. They were followed by Loeb, who was able to keep close to Subaru's Petter Solberg, who benefited from his better starting position during the first three stages. However, Solberg, in the new Subaru Impreza WRC 07, had to retire at the start of SS6 giving the lead to Loeb. After the first day, Ford identified and fixed a sensory fault in Grönholm's car. The problem had caused lack of engine power and troubled the Finn: "In the morning, I was sweeping. In the afternoon, I was sleeping". The second leg saw Grönholm quickly climb to second place, but Loeb continued setting top times and extended his lead to Grönholm from 43 to 60 seconds. Hirvonen, Chris Atkinson and Dani Sordo battled for the third place. Hirvonen was the fastest driver on the final day and secured the last podium position, ahead of Sordo, Atkinson, Manfred Stohl, Jari-Matti Latvala and Matthew Wilson. Loeb took the win 55.8 seconds clear of Grönholm.

The Corona Rally Mexico, formerly known as Rally America is a round of the FIA World Rally Championship. The rally entered the championship schedule in the 2004 season. The event's itinerary is based in the state of Guanajuato. The stages take place in the environs of cities of León, Silao, Irapuato and Guanajuato; rally headquarters being located at León.

In 2004, the Organising Committee won the Inmarsat Star of the Rally award for his first organized WRC rally. In 2008, the Organising Committee of the Corona Rally Mexico won the Abu Dhabi Spirit of the Rally award for the great work done in the organization of the WRC event.

Rally America, later known as Corona Rally Mexico and now Rally Guanajuato Mexico, was created in 1979 through a big spirit of co-operation by the two largest clubs in Mexico: Club Automovilístico Francés de México (CAF) and the Rally Automovil Club (RAC). Both clubs have a long history of sporting competition, so their collaboration was a big step forward for rallying in the country. It was originally hosted in the State of Mexico and ran continuously until 1985.

Marcus "Bosse" Grönholm (born February 5, 1968 in Kauniainen/Grankulla) is a Finnish former rally driver. Driving for Peugeot, he won the World Rally Championship in 2000 and 2002. After Peugeot withdrew from the World Rally Championship, Grönholm moved to Ford for the 2006 season and placed second in the drivers' world championship, losing the title to Sébastien Loeb by one point. The next year he again placed second, four points behind Loeb. He and his co-driver Timo Rautiainen retired from rallying after the 2007 season but returned to the championship in 2009 driving a private Subaru for a short period of time.

Grönholm also won the 2002 Race of Champions, taking home the Henri Toivonen Memorial Trophy and earning the title "Champion of Champions". At the 2006 Race of Champions, he formed team Finland with Heikki Kovalainen and the pair won the Nations' Cup.

Marcus' father, Ulf "Uffe" Grönholm, had been an active rally driver in the late 1970s to early 1980s, and with measurable success too, winding up twice Finnish champion. He was killed during a practice run for Hankiralli on February 25, 1981 in Kirkkonummi. Despite this connection, his son, only 13 years old at the time of his father's death, was latterly to refute any suggestion that it was Ulf, and not fellow rally-driving cousin (and occasional Peugeot factory squad team-mate at various points during the early 2000s), Sebastian Lindholm, who tempted him into following in his father's footsteps by also participating in the sport. In his teens Grönholm was fond of motocross as a recreational activity, but a serious knee injury forced a switch to boxing.

Henning Solberg (born 8 January 1973) is a Norwegian rally driver. Together with co-driver Ilka Minor, he currently competes in the World Rally Championship (WRC) with Stobart M-Sport Ford. Solberg is the older brother of the 2003 world champion Petter Solberg.

Henning Solberg was born in Spydeberg. Like his younger brother Petter, Henning started his career as a driver in bilcross (Norwegian low-budget rallycross similar to Swedish folkrace and Finnish jokamiehenluokka) and rallycross events, and switched completely to rallying in the mid 1990s. Between 1999 and 2003, he became the Norwegian Rally Champion for five years in a row.

After several events as a privateer in the WRC, Solberg got a contract with Bozian Racing for the 2004 season. At his first event with the Peugeot 206 WRC, the 2004 Swedish Rally, Solberg took his first WRC points by driving to sixth place. This remained his best result and only points-finish of the season.

For the 2005 season, Solberg was signed by the BP Ford World Rally Team, Ford's factory WRC team. He competed in seven rounds alongside Ford's main drivers Toni Gardemeister and Roman Kresta. His best result came at the Cyprus Rally, where he beat team-mates Gardemeister and Kresta to the fourth place. With nine points, Solberg finished 14th in the drivers' world championship.

Cato Menkerud (born August 23, 1973 in Lillehammer, Norway) is a rally co-driver. He started as a co-driver in 1992 for his father Helge Menkerud. In addition to Henning Solberg, he has co-driven for Petter Solberg, Birger Gundersen, Thomas Kolberg, Alexander Foss and Henrik Lundgaard. After the 2009 World Rally Championship season Menkerud split from Henning Solberg, and became the co-driver for Eyvind Brynildsen. In addition to being a co-driver he runs a gas station in Lillehammer, where he lives. He is married to Charlotte.
