Webber emerges as major F1 force
It is quite a change for the man who, for the first seven years of his career, was known as F1's unluckiest driver, and who before Red Bull hit their stride last year only very rarely had a car capable of competing at the front.
This season was expected to continue where 2009 left off - with Webber's team-mate Sebastian Vettel as Red Bull's lead driver and Webber picking up the odd win here and there.
But that is not the way it has worked out.
Germany's rising star continues to drive superbly - he has scored three pole positions, won a race, and lost two more because of reliability problems.
But Webber is heading into this weekend's Turkish Grand Prix on the back of two dominant victories in Spain and Monaco, having crushed Vettel at two very different circuits.
And, although tied on points with his team-mate, Webber is leading the championship by virtue of having won more races.
Webber has never before won two races on the trot - and whenever he has beaten Vettel in the past, the younger man has generally gone straight out at the next race and reasserted what he assumes to be the natural order.
No wonder, then, that Vettel was left bemused, confused and not a little shocked by his team-mate's stunning performance in Monaco, that ultimate test of a grand prix driver - 0.4 seconds quicker in qualifying, and in another league in the race.
And that is not even the whole story. As Webber put it after Monaco, he should have three victories and Vettel none - Vettel only won in Malaysia after Webber misjudged his advantage on the run down to the first corner and left the door open wide enough for his team-mate to slip through into the lead.
So what has happened? What has turned Webber from a quick and aggressive but sometimes inconsistent driver into a man who now appears to have become a consistent front-runner? And can he maintain his form?
BBC Sport visited Webber earlier this week at his beautiful house in Buckinghamshire to film an interview with Eddie Jordan which will be broadcast on BBC One this weekend.
Playing in his expansive gardens with his beloved dogs - a Rhodesian ridgeback called Simba and a German short-haired pointer called Shadow - Webber remains the same likeable, matter-of-fact, no-nonsense Aussie sportsman he has always been.
These are two serious dogs, that you would in no way want to mess with.
And, resplendent in pale blue jeans and a flowery designer Italian shirt, Jordan was understandably wary of producer Sunil Patel's requests that he get down to some rough and tumble with them for the sake of some "great TV".
But, not without reason, he likened Webber to a "shadow", sneaking up unawares on his championship rivals.
Almost certainly that is what partly explains Vettel's shocked response to Webber's recent wins - it just didn't compute; it wasn't what was meant to be happening.
Webber, with the wisdom of a man who has seen too much to get carried away, says he is "keeping my feet on the deck - we know we've got some pretty stiff opposition".
For Webber the driver, though, there is no doubt things have changed this year.
First of all, he feels much more at home in the 2010 Red Bull than he did last year's car - he talked after setting his brilliant pole position in Monaco of finding "another gear in terms of confidence in the car".

From that stems the willingness drivers need to push the limits, knowing the car will not bite them back for their adventure, and the ability to know how far is too far.
Vettel, though, shares a very similar driving style to his team-mate, so it cannot just be that.
Webber is also displaying a calm, accepting approach - realising that he cannot win all the races, and that Vettel is too good to beat all the time, he is neither getting too down following his poorer races, nor too up following his two great wins.
It was a very nasty accident and a very serious injury and, although Webber played it down, there seems little doubt that it affected his driving last season.
Certainly, he was far from fit when he first drove the 2009 Red Bull in winter testing in February - he was still on crutches. And clearly the injury affected his mindset and physical preparation, however slightly, throughout last summer.
Webber had an operation over the winter to remove most of the metal-work holding his right leg together, leaving only the titanium rod that runs down his shin still in place, as his tibia was still not fully healed.
His leg retains a nasty-looking circumferential lump not far above his ankle, but that is actually just some excessive re-growth caused by a bone intensifier used after the accident to stimulate healing.
So, fundamentally, the injury is healed, or at least healed enough for him not to have it at the back of his mind any more.
These sound like small things, but they add up to a lot at the very highest level of F1, where so much success depends on a drivers' mentality.
For those outside Red Bull, the fact that Webber now appears to be able to challenge Vettel on an equal basis is good news.
With the fastest car on the grid, and their drivers finally one and two in the championship after a tricky start to the season, it could be a long summer ahead if there was no competition within the team.
As Webber knows only too well, though, the bubble could burst at any moment, and he is concentrating on that great sporting cliché - taking each event as it comes.
Or, as he puts it: "It's still very early. The points can change very quickly, as we saw with JB (Jenson Button). He was leading the championship, he's had a tough few races and now I'm leading it. I'm just focusing on the sessions and my job."
He adds: "We did a good job with the car and I did a good job in the cockpit. I'm keeping my head down.
"We've got to keep staying in the hunt, that's the main thing. We mustn't underestimate the competition, we know that. But we're up for it and looking forward to the challenge towards the front."
