The Swede started the JWRC’s final leg with a sizeable lead in his Hankook-shod, GEM fuelled Ford Fiesta R2, which he preserved in both dry and then wet conditions. He finished 1min 47.5sec ahead of Michael Burri, with Yeray Lemes 2min 11.2sec behind in third.
Tidemand now holds a 42 point lead at the top of the standings with two rounds remaining in France and Spain.
“I started with a big advantage and really it was just a case of keeping up my concentration,” said Tidemand. “Saying that, I still managed to slide wide and clip a fence that really made me wake up a bit. I’ve been building my asphalt experience since Germany last year so it’s nice to win on this surface.”
Second marked Burri’s maiden JWRC podium, while Lemes delivered a determined recovery drive after a puncture on Friday ended his chances of victory.
Fourth went to Martin Koci while Jose Suarez, Tidemand’s closest championship challenger, was fifth. Suarez led early on but an accident and a time penalty dropped him down the order.
Marius Aasen was on course for a podium but a costly excursion in the final leg relegated him to 10th.
All 10 starters completed every stage of the three-day asphalt encounter, which included narrow and twisty vineyard roads in the Mosel region and demanding tracks on military land.
