The 2 phrases have usually been interchangeable when utilized by groups and drivers this yr, however Vowles says they aren’t the identical and are generated otherwise.
Mercedes appeared to have go on high of its porpoising problem with the W13 on the Spanish Grand Prix, however Vowles says the issues are very a lot circuit particular, with the smoothness of the floor taking part in a key position.
The difficulty of bouncing was exacerbated by the bumpy Baku monitor floor, which brought on excessive discomfort for the drivers, and particularly Hamilton. The seven-time F1 world champion had a distinct set-up in comparison with his teammate, together with another rear suspension.
“There may be positively a monitor by monitor ingredient and it’s a operate of how clean the tarmac is and the format of the circuit,” Vowles mentioned in a Mercedes video.
“I’d say Baku actually of the circuits we’ve had to date is on the more severe finish of it and conversely Barcelona in all probability on the higher finish of it.
“So, these two circuits positively will spotlight the strengths and weaknesses of the package deal. But it surely’s additionally value placing a little bit little bit of time into explaining porpoising, bouncing, bottoming – three phrases probably being spoken rather a lot with a little bit little bit of affiliation of being the identical factor however they aren’t fairly.”

Vowles famous that, because the Spanish GP indicated, the group has made progress on controlling porpoising. However in so doing, and thus with the ability to run the automotive decrease, bouncing has develop into a problem.
“We positively suffered porpoising within the earlier races and in Barcelona we didn’t,” he mentioned. “And we’ve made an amazing quantity of effort on our package deal to make it possible for we tried our greatest to resolve it, and I’m assured we’ve made a step.
“In Barcelona the automotive was secure, sturdy and we might decrease it and that’s the important thing, we managed to create a package deal had been aerodynamically we had been in a position to work with it much more, we might work with set-up and we might drop the vehicles when it comes to journey top producing efficiency.
“Come now to Monaco and to Baku, what that sadly uncovered is a second problem that was being masked by the primary. I’m assured we’ve made a step ahead when it comes to porpoising, however we very clearly have bouncing, and to the surface it seems to be virtually an identical, however there’s a delicate distinction between the 2.”
Vowles mentioned the bouncing is solely a operate of the automotive hanging the monitor: “What is occurring now could be that the automotive is decrease, because of fixing the primary problem, however now hitting the deck fairly laborious, and that’s creating the bouncing that you just see in the meanwhile.
“Once more, you attempt to extract efficiency by working the automotive low however the issue may be very totally different and the bumpier the monitor the extra the enter is clearly having an impact, which is what we noticed in Baku.
“I feel what’s clear is that we nonetheless have a protracted journey in entrance of us to study every little thing we have to, to be preventing on the entrance however maybe extra importantly you will notice efficiency variation monitor on monitor as we go ahead. Canada for positive will probably be very totally different to Silverstone when it comes to how our automotive performs.”
Vowles conceded that the group made life too tough for its drivers in Baku, whereas confirming Hamilton will probably be match and prepared for this weekend’s race in Canada, regardless of Toto Wolff expressing considerations on Sunday night time.
“I’m happy to report that Lewis is right here this morning [at the Mercedes factory], I spent a couple of hours with him and he’s okay, he will probably be again within the automotive in Montreal,” Vowles mentioned.
“He’s an elite athlete that may push the bounds of endurance of himself and the automotive and that’s what F1 drivers do, that’s what makes them distinctive.
“On this event, although we pushed the package deal and our drivers too far, we’re placing them into vital discomfort and we merely can’t do this once more.
“Our drivers aren’t the one ones struggling, you will notice within the media quite a few feedback from quite a few drivers who’re equally in discomfort and ache. And now we have a accountability now to make it possible for this doesn’t keep on.”

The group was mystified by Hamilton’s “chilly seat” remark in Baku, however having talked to his driver Vowles mentioned it was a bodily relatively than mechanical problem.
“What occurred is, nothing actually had modified within the automotive, it simply seems to be like after the quantity of pummelling his again had taken from the bouncing, he basically had a numbness that set in and it seems to be just like the chilly was a response to that.
“There wasn’t something colder within the automotive, it was only a response to the quantity of endurance and ache he had been via within the race.”
