The German quartet of Franziska Preuss, Andrea Henkel, Franziska Hildebrand and Laura Dahlmeier missed just three targets between them on their way to recording a winning time of 1:06:27.8.
The Germans' run of three wins in five races stretches back to their triumph in January last season at Antholz.
Henkel and Dahlmeier did not miss a single target as the latter eased to victory in the final leg, finishing 23.3 seconds ahead of second-placed Ukraine, who won the first women's relay of the season in Hochfilzen.
Julia Dzhmya endured a difficult first leg - failing to hit three targets - but Vita Semerenko, Valj Semerenko and Olena Pidhrushna missed once between them to hold off Norway by 0.5 seconds.
In contrast the Norwegian team Tiril Eckhoff, Fanny Welle-Strand Horn, Synnoeve Solemdal and Tora Berger struggled with their shooting, accumulating ten missed targets in total.
Switzerland held the lead after the first leg through a flawless display from Selina Gasparin but subsequently fell away to finish 13th.
