Christian Taylor, Laura Muir, and Hyvin Kiyeng post world leads as Warholm and Duplantis miss WRs
Triple jump king produces another winning leap in the last round as British middle-distance star sprints to victory at ISTAF meeting in Berlin.
Double Olympic triple jump champion Taylor left it late to produce the best leap of 2020 while Muir surged clear to clock the fastest 1500m of the year so far.
There was also a world lead performance in the women's 3000m steeplechase as Kenya's Hyvin Kiyeng took victory in 9:06.14.
Johannes Vetter won the javelin although the home crowd did not see him throw beyond 90 metres as he did last weekend in Poland, while Germany's long jump while champion Malaika Mihambo was beaten by Ukraine's Maryna Bekh-Romanchuk.
Warholm comes up just short once more
The two-time reigning world champion was just nine-hundredths of a second outside Young's mark three weeks ago in Stockholm, hitting the last hurdle on his way to a new European record.
There were no obvious setbacks today after the Norwegian blasted out of the blocks in lane seven.
From the halfway point, it was clear that his only opponent was the clock.
As it was, he crossed the line in a meeting record of 47.08s just three-tenths outside his target.
Afterwards he told broadcasters ARD, "I was really tired as usual [at the end] but I love running on this track and it's very fast and I felt like I got a really good lap so I'm really happy with my race today.
"I'm coming closer and closer and this year I'm running very low 47s and had a race under 47 seconds. It's been a very good season and when you do consistently good times, records can come."
Warholm has given up beer since winning the 2018 European Championships in Berlin, and revealed that water would be his celebratory drink this evening.
He added, "In Norway, my Oktoberfest is cancelled because of coronavirus. I'm going to stick with water and get ready for next season, hopefully the Olympics and everything. I've got to play it serious."
Laura Muir produced another commanding display in the 1500m, clocking the fastest time in the world this year.
Britain's European champion was already clear of her rivals when the last pacemaker dropped out with over a lap to go, and she kept the hammer down to win in 3:57.51.
Fellow Briton Laura Weightman took second place in a new personal best of 4:00.09.
Christian Taylor pulled out another sixth-round special to take the triple jump.
The two-time Olympic gold medallist and four-time world champion was in second place after five rounds with former European champion Max Hess leading on 17.17m.
But the American, just as he had in Ostrava last week, then produced a new world-leading leap of 2020.
He jumped 17.57m, 11cm further than his previous best this season, to return to winning ways after a below-par showing in Samorin on Friday.
This was his first ISTAF Berlin competition and one he called afterwards a "bucket list dream".
"Since 2009 I always said if I get the chance to compete here, it will be a dream come true. In 2018 I came to support my fiancee (Austrian hurdler Beate Schrott). I cried because it meant so much to me.
"This is what we need to do - put on a show. We need to entertain. And in the end the crowd was really happy.
"The history... Jesse Owens is so special to me. Yesterday it was his birthday. The history and the city, the people know so much about athletics, they are so welcoming. I train in Vienna, I was in the US until June. But when it got worse with Covid, it was good to train in Europe. And then my preparation got much better.
"I knew that a world lead was possible today. I only needed competitions. I did not get the head-to-heads that I normally get. Now I will spend one month in Vienna and Innsbruck and the lakes and take some time off. On October 1st we will start with the preparation for 2021."
Taylor said he would not compete indoors in that preparation for 2021 when he will bid for a hat-trick of Olympic titles in Tokyo.
Mondo Duplantis had something of a scare on his way to victory in the pole vault.
Sweden's pole vault world record holder failed on his first attempt at 5.82m and passed on the height when Piotr Lisek went over at the first time of asking.
He then failed with his first attempt at 5.91m to leave him on the brink of his first defeat of the year.
But he got it right when he needed to and took victory before three unsuccessful attempts at 6.15m, one centimetre higher than Sergei Bubka's outdoor world record going back to 1994.
Stahl's best was 65.89m with the Lithuanian throwing 66.09m in round three before underlining his victory with a final-round effort of 66.72m.
After his mammoth 97.76m throw in Chorzow, Poland last weekend, big things were expected of Johannes Vetter on home soil in the javelin.
The 27-year-old could not quite deliver this time, but his second-round effort of 87.26m was more than good enough for victory.
Afterwards he said, "If the atmosphere had not been as good as this, I would not have been able to throw 87 metres again. The supporters totally helped me with that.
"The last couple of weeks were very hard, both physically as well as mentally. I absolutely wanted to keep the excitement real and not lay back after my success.
"I am very satisfied with the 87m throw, because the practice throws did not go as planned. My fourth successive victory at ISTAF, that is absolutely amazing!"
There was disappointment for the home fans as world champion Malaika Mihambo suffered defeat in the long jump.
Her best jump of 6.77m was not quite enough as Maryna Bekh-Romanchuk came out on top with a 6.87m jump in round three.
Ta Lou's fellow Ivorian Arthur Cisse took the men's event in a season's best 10.10s.
