With injuries to regular team-mates Thomas Lamparter and Alex Baumann, Hefti began this season on the European Cup circuit however he's showed few signs of rustiness.
The 34-year-old took two-man victory at the last World Cup round in Winterberg before finishing second in the same competition in La Plagne on Saturday.
And if that form wasn't enough to show that the Swiss three-time Olympic bronze medallist was back with a bang he underlined it with a four-man victory on Sunday.
The foundations for the win were laid with a hugely-impressive first run of 58.86 seconds and with a solid second effort of 59.06 they were able to hold off Russia's Alexsandr Zubkov.
Zubkov won the last four-man World Cup round at Winterberg but he had to settle for second in France, his time of 1.58.01, 0.09 seconds outside Hefti who clocked 1.57.92.
There was a second Russian presence on the podium in the shape of Alexander Kasjanov who took third place in a time of 1.58.18, 0.17 seconds shy of his compatriots.
British driver John James Jackson bagged his third consecutive eighth-place World Cup finish having ended in the same position in the two-man event a day previously and in the four-man at Winterberg last time out.
