The 60-year-old will drive a brand-new Toksport Škoda Fabia RS Rally2 in the championship’s premier support category - 29 years after he won the Monaco-based fixture with a Ford Escort RS Cosworth in 1994.
Delecour was a frontrunning FIA World Rally Championship driver in the 1990s and early 2000s. He won four WRC events and drove for manufacturers including Ford, Peugeot and Mitsubishi.
The Frenchman still regularly competes today and next month’s fixture will mark his 23rd Monte-Carlo start.
