The trio of Laura Trott, Joanna Rowsell and Dani King blasted around the polished boards to ear-splitting roars from another capacity crowd, smashing their own world record again with a time of three minutes 14.051 seconds.
Trott, at 20 years and 102 days, became the youngest gold medallist in women's events in cycling track at the Olympic Games, breaking the record of Australia's Anna Meares when she won the 500m time trial at Athens 2004.
Such was their searing pace that at one stage it looked as though the British team, unbeaten in 2012, might even reel in the U.S. trio of Sarah Hammer, Dotsie Bausch and Lauren Tamayo.
The Americans avoided that humiliation but still finished more than five seconds back in the 12-lap event.
"Words can't describe how I'm feeling right now. I'm so happy for us all. We came together tonight. We're such an amazing team. We couldn't have done it without each other. I'm just ecstatic," King told reporters.
"Words can't describe it. I've never been so happy in my life. They kept us going in that last kilometre. You couldn't even feel your legs, you were just driving forward."
Britain, who had also broken their own world record in the opening round, added the Olympic crown to the world title they already owned and took Britain's tally of golds on the track to four, with more to look forward to.
Former Beatle Paul McCartney joined in the celebrations, leading a stirring rendition of "Hey Jude" that reverberated around the iconic arena in east London.
In the bronze medal match Canada beat Australia.
The team pursuit event is one of four women's events making their debut at the London Velodrome along with the team sprint, keirin and omnium.
