The Swiss rider is a Big Air specialist, having picked up bronze at X Games and winning the Frostgun Invitational last week.
But he proved he can also cut it on a slopestyle course by posting a score of 91.75 on his first run in the finals that would eventually prove unbeatable.
His countryman Andri Ragettli was close behind but his final run score of 91.00 just not enough to put the 16-year-old on top while defending champion of the Vars course, American McRae Williams, rounded off the podium.
And after a packed contest schedule including a couple of big wins Ambühl is looking forward to a well-earned rest.
“I’m stoked that I landed my first run and that I could give the crowd a show. It’s nice to have so many people up here,” he said.
“I’m going home to rest for a couple of days. I’ve had around four competitions in ten days and it was pretty tough so I’m stoked to go back home.”
He won’t have much time to put his feet up however with the third round of the SFR Tour coming up on March 1st – the AFP World Tour Platinum event in La Clusaz.
And the race for the overall SFR Freestyle Tour title is also wide open now with the top two finishers at the first stop, Fabian Bosch and Oscar Wester, missing the contest in Vars – the former picked up an injury in practice.
Williams looked like he would be the man to beat in the finals after winning both the qualifying round and the semi-final heat but Ragettli was always right on his tail.
However, Ambühl put pressure on the rest of the field by laying down a huge run on his first attempt and crashes in the final round cost some of the major contenders as they tried to catch up.
In the women's competition Kelly Sildaru made it two wins out of two in the SFR Tour this season while Isaac Simhon topped the podium in the kids event.
