Loix's career in motor sport began in karting at the age of 15. In 1990, he bought his first rally car, a Lancia Delta group N, though he soon progressed to a Mitsubishi Galant Group N. 1993 saw a big step forward in Loix's career as he became part of the Marlboro World Championship Team driving an Opel Astra and he became the Belgian F2-champion. Nicknamed Fast Freddy by his fans, he made the switch to four wheel drive in 1996 with a Toyota Celica GT-Four and completed 3 World Rally Championship events and a further 6 in 1997. This period saw continuing sponsorship with Marlboro and a switch to the new Toyota Corolla WRC. He took the lead in the 1997 Sanremo Rally but mechanical problems brought an end to his charge for victory. Loix and his co-driver, Sven Smeets, moved to Mitsubishiin 1999 and campaigned a Mitsubishi Lancer Evolution VI. His first year with Mitsubishi proved to be a difficult one with Loix being injured in a horrific accident during the Safari Rally. Despite the setback, Loix fought back and achieved 4 fourth places. . In 2001, and after several successful seasons, the Mitsubishi Lancer, being a Group A car, found itself outdated and incapable of competing on the same level as the new WRC cars that the other teams were running. Loix signed a two-year contract with Hyundai at the start of 2002. This was a difficult season in the Hyundai Accent WRC and his best result was 6th place on the Rally Australia. Due to funding cutbacks in 2003, the team couldn't develop the car further and Hyundai retired from the WRC following 2003's Rally Australia. A drive for Peugeot in the last rally of the 2003 calendar, the RAC Rally in Great Britain, not only saw him replace the by then ailing 2001 World Rally ChampionRichard Burns, it also saw him finish in 6th place overall in that year's rally. In the 2004 season, Loix completed only 5 WRC events, all for the factory Peugeot team again, in a Peugeot 307 WRC before retiring from the WRC later that season after the 2004 Rally Catalunya. Since 2007 Loix has been competing in the FIA Intercontinental Rally Challenge with Peugeot Sport Belgium, driving a Peugeot 207 S2000. Loix is currently the most successful driver in IRC with a total of seven wins, including a hat trick in 2010.
