 G.D.M 

• Motor racing is a family affair for the De Mévius clan. Guillaume and his brother Ghislain are following in their father's footsteps. Grégoire has competed in eight Dakar rallies (best result: 8th) and co-founded Overdrive Racing with Jean-Marc Fortin. His second son cut his teeth in rallying in Belgium before securing a drive with Citroën for the 2019 WRC2.
• The native of Namur competed in his first Dakar in 2022 with the Red Bull Off-Road Junior team, which ran the lightweight OT3 prototypes developed by Overdrive. He eventually retired from the rally, but scored a category stage victory. He then took charge of the OT3 project, renamed G Rally Team OT3, with the G standing for the initials of the De Mévius boys. Guillaume competed in his second Dakar in 2023, wearing two hats as manager and driver, sponsored by Nasser Al Attiyah. Leading the T3 category for two days, he finished in an impressive third place.
• The Red Bull programme saw its first talents emerge, including him. He entered the Ultimate category and competed in his first Dakar in 2024. He won stage 1, becoming the first Belgian to win a special stage since Stéphane Henrard in 2003. He finished 2nd overall and confirmed his status as one of the new faces of world rally-raid racing.
• Contacted by several constructors, Guillaume chose Mini for the 2025 edition, impressed by the brand's long-term vision and the three-year contract it offered, as well as by the support provided by X-raid. Mathieu Baumel joined him in the adventure, and they secured a stage victory in their first Dakar together. Problems encountered with the Mini JCW Rally 3.0i prevented them from aiming higher in the general classification (21st).
• Guillaume planned to compete in the 2026 Dakar Rally with Baumel, and he remained fully committed to this plan despite Mathieu's accident, which resulted in the amputation of one of his legs. The Belgian immediately supported him in his intention to return to competition and drove alongside his former navigator, Xavier Panseri, during the Frenchman's rehabilitation.
