After leaving Ford, Delecour was hired by Peugeot to head their campaign for the French Rally Championship, driving the Peugeot 306 kit-car. He finished third in the championship in both 1996 and 1997, winning several events outright along the way. Moreover, he also contested some of the asphalt rounds of the World Championship, where the Peugeot was fast enough to be a contender for outright victory. He finished fourth on both the 1996 and 1997 Tour de Corse. Subsequently he was involved in the early years of the Peugeot 206 WRC project, which saw him return to the World Championship for the 1999 season. He did not win any events, but scored consistent top-ten finishes, including second place in Corsica and San Remo, the latter marred by acrimony between Delecour and team-mate Gilles Panizzi, who went on to win the event.
