Often at loggerheads on the track which has occasionally resulted in a war of words off it, for once the Red Bull pairing find themselves singing from the same hymn sheet when it comes to Mercedes.
The Brackley-based marque face an International Tribunal with regard to their use of a 2013 car in a tyre test with Pirelli at Barcelona's Circuit de Catalunya last month.
Mercedes have declared their innocence, insisting they were there at the request of Pirelli to test nothing but new tyres, predominantly for next season.
Pirelli, in turn, has stated Mercedes were not privy to any data or information produced from the test conducted from May 15-17, a few days after the Spanish Grand Prix.
Webber, though, feels there is no smoke without fire as any test always provides some meaningful insights, regardless of the circumstances.
"There's no beating around the bush, it's a nice scenario to go to the venue you have just competed at," said Webber.
"It's quite an attractive option to take your race drivers and get a feel for it.
"There is no reference point apparently (with regard to the tyres). That's how Pirelli do their tests.
"But you would assume the baseline is pretty close to what we are racing, so you're going to get a pretty good idea if something is moving in a good or negative fashion.
"You're not going to learn nothing as a driver.
"It's not probably as powerful for a driver as a normal test because then everything is more transparent, especially from a factory point of view.
"But you can also test some options from a car side. From a team perspective that's a lot more powerful than it is for the drivers."
Three-times champion Vettel was in full agreement with Webber as he said: "I don't know exactly the tyres they used, but I think you always learn when you are on the track.
"At some point you use tyres you have already used, or that you will use in the future, so in that regard every lap matters.
"We all know how important testing is in the winter. The quality of the testing is not the same because the conditions are different.
"The cars are very early in their development, so if you have the chance somewhere in the middle of the season to have a test, or three days, then it's a big help."
Mercedes employed race drivers Lewis Hamilton and Nico Rosberg for the test, yet despite the furore being the main talking point ahead of this weekend's Canadian Grand Prix, the former is staying single-minded.
"I'm not focused on it. I'm focused on trying to get myself ready for this grand prix," insisted Hamilton, a three-times winner of this race.
"As far as I'm concerned it's not a distraction for the team. The important people in the team are dealing with it in the appropriate way, and I'm just hungry to win."
