Matton’s interest in motorsport developed during his childhood in Huy, where he followed the Rallye du Condroz annually. In 1986, shortly after obtaining his driving license, he made his competitive debut at the same event driving an Opel Ascona. While pursuing a degree in business administration, he continued to engage with the sport, eventually founding his first racing-related business in 1990.
In 1990, Matton established Prorace, a company specializing in the preparation and rental of racing vehicles. The firm achieved early success in national championships, supporting Janusz Kulig to a runner-up finish in the Polish two-wheel drive championship and Eddy Van den Hoorn to a title in the Dutch Group N championship. By 1996, Prorace began its association with the Citroën brand through the Citroën challenge, fielding drivers Frédéric Beco, Davy Vanneste, and Thierry Bragard.
Matton transitioned into team management roles between 1997 and 2001 with the Belgian outfit Future World. There, he managed Subaru Impreza WRC programs for drivers Bruno Thiry and Renaud Vereydt. The team eventually functioned as a local branch of Toyota Team Europe (TTE) for championships across Belgium, the Netherlands, and Poland.
In 2001, Matton joined Kronos Racing as Team Manager, overseeing the WRC programs of Simon Jean-Joseph and Kris Princen in Peugeot 206 WRC machinery. This experience led to his first appointment at Citroën Sport at the end of 2002, where he initially served as Logistics Manager. He rose through the ranks to become WRC Coordinator and eventually Team Manager under Guy Fréquelin.
During this first spell at Citroën, Matton also acted as customer racing manager. In this capacity, he monitored the development of young drivers, including Dani Sordo and Kris Meeke. Under his supervision, Sordo and Meeke finished first and third respectively in the 2005 Junior World Rally Championship (JWRC) driving Citroën C2 Super 1600s.
In 2008, Matton departed Citroën to found MY Racing. Although independent, the company maintained a commercial relationship with Citroën by distributing racing parts in Western Europe and organizing the Citroën Racing Trophy until 2013. During this period, he also managed the racing program for Saudi driver Yazeed Al-Rajhi in the Middle East.
Matton returned to Citroën Racing as Team Principal on January 5, 2012, succeeding Olivier Quesnel. His primary mandate from Citroën CEO Frédéric Banzet was to manage the team’s transition following the retirement of Sébastien Loeb from full-time competition.
The 2013 season served as a transitional period. Matton secured a partnership with Abu Dhabi Racing and managed a driver lineup consisting of Mikko Hirvonen, Dani Sordo, and Khalid Al-Qassimi. While Loeb competed in only four rallies that year, Matton utilized the time to oversee the development of the Citroën C-Elysée for a move into circuit racing. By 2014, Matton was managing dual factory programs in the WRC and the WTCC. The touring car squad featured a lineup of Loeb, Yvan Muller, José María López, and Ma Qing Hua.
In early 2018, Matton left Citroën to become the FIA Rally Director. In this role, he was responsible for overhauling the rally pyramid and supervising the FIA Rally Star detection program. His tenure saw the WRC commit to a hybrid power era through agreements with manufacturers and the series promoter. Additionally, Matton negotiated an agreement between the FIA and ASO to establish the first FIA World Rally-Raid Championship, which launched in 2022. He resigned from the FIA on December 22, 2021, and was succeeded by Andrew Wheatley in March 2022.
As a driver, Matton’s competitive career was sporadic, though he campaigned a variety of notable machinery including the Opel Manta 400, Ford Sierra Cosworth, and Ford Escort Cosworth. He was frequently accompanied by prominent Belgian co-drivers such as Luc Manset, Stéphane Prévot, and Jean-Marc Fortin. His highest competitive achievement occurred in 2013 at the Rallye du Condroz, where he finished third overall in a Citroën Xsara WRC, partnered by co-driver Daniel Elena.
Following his departure from the FIA in 2022, Matton returned to Belgium to lead MY Vintage, a division of his company focused on classic racing vehicles. He also established MY Gallery, a specialized department providing trading and advisory services for investors in collectible racing cars.
In 2017, Matton faced a two-year probation period following a failed doping test. This occurred shortly before his transition from team management at Citroën to his regulatory role at the FIA.
