Shiffrin once again showed her superiority. In the first run down the piste, she gained a lead of 0.83 seconds over the second place, the Swiss Camille Rast.
The margin of victory a few hours later: 1.55 faster than Rast and 1.71 ahead of third place, German-Swedish Emma Aicher.
"I don't ask any questions. Sometimes you just have to push," Shiffrin told Viaplay after her 68th slalom victory.
Shiffrin can add Courchevel to Levi, Gurgl and Copper Mountain as places where she has racked up new victories this winter. In total, they have reached 105 – more than anyone else in Alpine World Cup history.
"It's crazy. I appreciate it so much. You want to lock in this feeling," the American continues.
Swenn-Larsson sixth
Anna Swenn-Larsson and Sara Hector were fifth and seventh – within a hundredth of a second – in a close race. But Hector's journey came to an early halt. Swenn-Larsson's effort was a bit choppy, but she made it to the finish line and finished sixth.
Swenn-Larsson and Hector have long been ready for the Olympics, but they are also the only Swedish alpine skiers who have received the go-ahead.
Despite the success in Copper Mountain last time, the Swedish Olympic Committee failed Estelle Alphand when the Swedish Olympic squad was expanded with several active players on Tuesday.
Alphand is primarily competing for a place in giant slalom. There, the internal competition is milder than in slalom, where Swenn-Larsson and Hector hold two of the four places.
Alphand drove out
The Swedish-French sister reached the second run, but she straddled a stick early on.
Cornelia Öhlund is also in contention for the Olympics, but needs to show why she should be allowed to compete in Cortina. Öhlund was eleventh and 2.64 behind Shiffrin after the first run. She finished eleventh, 3.60 behind the American.
Hanna Aronsson Elfman doesn't make it. Placed 21st after the first run, she finished 22nd.
