"It's a very good feeling after a difficult weekend for me," said the 23-year-old. "I showed some very good speed [on Friday] but unfortunately a strange choice of tyre compounds this morning knocked my confidence. But this year is all about learning and for my second time here I've gained some good experience. Now I'm looking forward to putting that into practice when I come back next year."
François Delecour, who was a late addition to the entry list for the event that he won 20 years ago, achieved his stated aim of a top six finish by claiming fifth place behind Breen, having overcome an assortment of problems with the Munaretto Sport Peugeot on day 1.
Julien Maurin took sixth place ahead of Andreas Aigner, who was the leading ERC Production Car Cup driver at the end of the race in his Yokohama-shod Stohl Racing Subaru Impreza R4 STI after winning an early battle for position with Renault's Germain Bonnefis thanks to an incorrect morning tyre choice by the Frenchman which dropped him to ninth by the end of the rally bit which still meant top points for Renault Sport Technologies in the ERC Production Car Cup for Team
Jean-Mathieu Leandri recovered from a late puncture to take eighth for Saintéloc Racing, which meant that he also picked up the honour of being the top Corsican driver home after Jean-Marc Manzagol had retired on stage nine. Behind Bonnefis, Jean-Michel Raoux completed the top ten in a Delta Peugeot.
Kornél Lukács was first home in the ERC two wheel drive championship after a puncture and an off wrecked long-time leader Pierre-Antoine Guglielmi's hopes. Molly Taylor secured the ERC Ladies' Trophy with a strong second-in-class, with Vasily Gryazin third.
Elsewhere, Antonín Tlusák was the GPD Mit Metal Racing Team's top finisher in 11th once place ahead of his team-mate Jaroslav Orsák, a result that hands the Czech squad a comfortable lead in the European Rally Championship for Teams.
Marco Tempestini was the leading Napoca Rally Academy driver home in 16th, but there was late disappointment for Daniel Oliveira who went off the road on the final stage when running in the top 10.
Former F1 driver Robert Kubica spent Saturday watching from the sidelines, after Citroën opted not to restart him after his mechanical failure on the first day of the Tour de Corse.
"It's a pity that we retired as I felt very good behind the wheel," he said as he watched the climax of the rally. "I was in the lead without having done any mistakes and I am satisfied with this and our tyre choices, which were very complicated with the changing weather conditions. I was here to learn and although the rally was short for me I've got more important experience."
