The words multi-21 mean nothing to you unless you're an F1 fan.

In March 2013, they became immediately iconic, and to this day, Mark Weber's furious delivery of that phrase behind the podium at the Malaysian Grand Prix is one of the defining moments

from his spiky rivalry with teammate Sebastian Vettel during their time together at Red Bull.

Do not adjust your podcast player, you are hearing this right. Bring Back V10s has veered off

course into the V8 era for our latest episode as we revisit everything that went on around this race

early in the final season of normally aspirated engines in F1. I'm Glenn Freeman and joining me

for this special episode are two men who know the V8 era of F1 very well, Ed Straw and XF1

driver and now Sky Sports expert Karun Chanduck.

Karin, welcome to what I suppose we should call Bring Back V8s.

When you think of Malaysia 2013, dare I ask, what's the first thing that comes to mind?

I mean, it's got to be that moment in the cool down room, isn't it?

Weber slams, drinks bottle on the table and goes multi-21 step. You know, as you said at the top, that was a, you know, a phrase that none of us had heard of. And frankly, you know, I don't think anyone outside the sport would have, would even know what we're talking about,

as you rightly said. But it's become such an iconic part of Formula One rivalries at that moment.

So yeah, absolutely that cool-down room moment where we heard Mark say it for the first time.

And Ed, you'd been covering F1 for many years by this point, and you were in Malaysia that weekend. So what's your standout memory? Yeah, it comes from slightly before that. Again, the same topic. Mark Weber making his displeasure known. If you watch the finish of that, Vettel crosses the line, waving near the pit wall. Weber goes completely to the opposite side of the track, kind of just to say, I not celebrating with a pit wall, and then once he's finished, he just chops across the track right across the

bowels of Vettel to make his displeasure known. That always stands out in my mind because we were

following that race in the media centre without any kind of audio, so it was actually quite

difficult to know everything that had been transpiring. I was getting some messages from people who are actually watching the coverage from home. So I was starting to get a bit of an understanding of what was going on. But that was the thing that really hit me to say, oh, Mark Webber's really, really unhappy about this. And then of course, all the other stuff followed. Yeah, and we're going to spend plenty of time getting into that. Before we get

going, this is your last chance to get your questions in for our series finale episodes where

we'll be answering your questions about anything to do with the V10 era of F1 from 1989 to 2005,

as by the time our final regular episode of the series is released, we'll have already started recording

the Q&As. So now is your last chance. Let us know your questions using the hashtag bring back v10s on
