Johannes Hösflot Kläbo of the last leg was able to parade to the gold without losing his temper.
It was Norway's twelfth straight relay gold in the WC.
Kläbo is now up to nine and touched Björn Dählie.
- Norway could have had a second and third team that fought for the medals, say the commentators on NRK.
Already after one kilometer, Norway's starter Hans Christer Holund put in a powerful jerk at the bottom of the uphill and was then able to drill solo.
He replaced the second leg's Pål Golberg with a 25-second lead to the big bunch where Sweden's Johan Häggström was seventh.
- It was extra nice to be able to deliver today.
There were probably four, five others who could have taken my distance, says Holund to NRK.
Norway had an abundance of riders to pick from.
On the second leg, Jens Burman, received a verbal warning for obstruction, was up for a while and pulled before Iivo Niskanen pedaled away for Finland.
Jens Burman shifted fourth and was with France, Switzerland and Canada chasing Finland 38-39 seconds ahead of the silver spot.
William Poromaa stayed with the group he went out with and replaced Calle Halfvarsson just over half a minute after Finland's Niko Anttola
