Great Britain have completed the trifecta - men's team pursuit world champions, world record holders and now Olympic gold medallists.
After Australia made an early challenge in their London Games gold-medal ride-off on Friday, the British were too strong and broke the world mark again as they successfully defended their Olympic title.
Geraint Thomas, Ed Clancy, Peter Kennaugh and Steven Burke became the first squad to go under three minutes and 52 seconds, clocking 3:51.659.
The British broke their own world mark set in qualifying on Thursday with 3:52.499.
Australians Jack Bobridge, Glenn O'Shea, Rohan Dennis and Michael Hepburn again had to settle for second behind the British with 3:54.581.
The British were again simply way too good for the rest of the competition.
But the Australians were also slower than at the April world titles, when they rode 3:53.401 to finish only .106 of a second behind the British.
Omnium rider Glenn O'Shea again fell off the pace and the Australians opted not to use teenager Alex Edmondson in any of the three team pursuit rounds.
The good news for the Australian cycling team is they have at least bettered their dismal showing at the Beijing Olympics, where Anna Meares' sprint silver medal was their only podium finish.
Meares and Kaarle McCulloch won the team sprint bronze on day one of the Games track program.
It was Great Britain's third cycling gold medal at their home games.
After a disappointing start in the men's road race last weekend, they have now hit top gear and are on target to emulate their eight cycling gold medals at the Beijing Games.
