Mikkelsen, whose Skoda UK Motorsport mechanics had completed an extensive overhaul of his Fabia at midday service including fitting a replacement gearbox, driveshafts, propshaft and steering following a torque link bolt failure on stage 10, was on course for his first podium of 2011 had he not hit trouble.
“I've never been so disappointed on a rally as I am now,” said the 21-year-old, who eventually took sixth place by winning the event-closing special stage. “We were taking the same lines as before and driving at the same speed. Suddenly I could feel there was no air in the front-right tyre [even though] we hadn't hit anything.”
Peugeot France's Bryan Bouffier, who briefly led on Friday morning only to drop back with a puncture, began the final day in sixth overall but fought his way to fourth with a succession of impressive stage times. However, his challenge came unstuck when he crashed out on the final stage.
Pierre Campana set the second fastest time on Saturday's opening test in his Munaretto Peugeot. But after losing ground on the next stage with an intercom glitch, the Corsican elected to focus on preserving a strong finish on his home rally, rather than risk going off the road on his first appearance in the IRC in a Super 2000 car. However, a front-right puncture five kilometres into the final stage looked to have scuppered those hopes. But with Bouffier crashing, Campana was able to clinch a hugely impressive fourth.
Frenchman Julien Maurin overcame brake and tyre wear problems to secure his first IRC points aboard his M-Sport Ford Fiesta S2000 in a strong seventh overall. Brake problems also slowed Bruno Magalhaes on day two but the Peugeot Sport Portugal ace was able to improve his confidence behind the wheel as the event progressed to clinch a solid fifth.
Finn Toni Gardemeister, in a TGS Worldwide Skoda Fabia, scored points for the third event running in eighth, having spent much of the event experimenting with different set-up options. The Finn had to limp through the final stage with a broken gearbox.
Patrik Sandell took ninth on his IRC debut with Skoda Sweden with Corsican Jean-Mathieu Leandri fighting back from a front-right puncture on stage nine to clinch the final point in P10. Sandell, a favourite for a podium finish before the start, was never able to find an optimum set-up although his efforts weren't helped by a broken rear differential on Saturday morning. He also admitted to struggling to adapt to the tight and twisty Corsican stages. He started the final day in 11th but snatched two championship points.
Toshi Arai brought Subaru's R4-specification Impreza to the finish in 13th overall on its first competitive outing. Florian Gonon landed IRC Production Cup honours in his N4 Impreza with Corsican Pierre-Antoine Guglielmi winning the IRC 2WD Cup in a Clio R3.
Guy Wilks slid off the road from third overall on Saturday's second stage, where the Peugeot UK driver remained stranded. Saudi Arabian Yazeed Al Rajhi, in a Kronos Racing 207, finished an encouraging 14th on only his third asphalt rally.
The 2011 Intercontinental Rally Challenge now continues next month with the Prime Yalta Rally in Ukraine, which runs from 2-4 June.
