Mercedes gave its W13 automobile a maiden run-out at Silverstone again in February when the UK was being hit by Storm Eunice that had wind gusts reaching over 120 mph, inflicting quite a lot of journey networks to close down.
George Russell described the wind on the day as being “completely loopy”, however it additionally had the influence of that means Mercedes didn’t get a full image of simply how dangerous the porpoising drawback could be till the primary correct check in Barcelona.
Mercedes trackside engineering director Andrew Shovlin mentioned that whereas the crew had mentioned potential points with the return of floor impact, it had not “forecast the type of mechanism that was truly troubling us.”
“After we have been at Silverstone, it was the center of a storm, we have been in 70 mile an hour winds,” Shovlin advised Motorsport.com in an interview wanting again on Mercedes’ season to this point.
“You typically begin with a automobile fairly excessive for shakedowns and issues, simply to keep away from damaging it after which drop it later. And through that day, we did run the automobile at a traditional journey, and began to see the difficulty.
“But it surely was solely once we obtained to Barcelona that you would truly take a look at it correctly on an inexpensive circuit and begin to perceive what was occurring.”

Whilst Mercedes introduced updates to the automobile for the second check in Bahrain, the crew continued to wrestle with its automobile bouncing, one thing that continued nicely into the season and hindered its probabilities of competing with Purple Bull and Ferrari on the entrance of the pack.
Shovlin appeared again on pre-season testing and the chase for solutions as a “peculiar time” for Mercedes, calling porpoising “maybe probably the most difficult factor we have ever needed to get our enamel into.”
“However that progress was fairly progressive and fairly encouraging, every little thing we have been doing was was making an increasing number of sense,” Shovlin mentioned.
“What we hadn’t actually appreciated was that the issue was very very similar to the layers of an onion. You peel that one, you are all the time wanting on the similar factor, regardless of what number of layers you have been taking off. And we realised that there is a few mechanisms at play.
“The difficulty is that coping with that problem while going racing is much more emotional, much more tough, much more worrying than coping with it again within the manufacturing unit once we can discover issues in our personal time.
“The beginning of the yr was tough, coming from being a crew that can go to nearly each race for the final variety of years considering we might be pole and win it, realizing that at finest we have been in direction of the entrance of the midfield, was fairly a problem.
“However the actuality is there is a vital lag between the understanding within the manufacturing unit and the race automobile truly going quicker. And Barcelona was the primary time that we have been in a position to actually put any of that studying into apply on the monitor.”
The problems compelled Mercedes to reset a few of its technical considering. Shovlin mentioned that had it solely been specializing in the Bahrain season-opener or the early races, it will have “most likely gone down a way more experimental route”, however the crew as an alternative centered on looking for out a long-term repair for the issue.
“At that time, we, as engineers, have been taking a look at it from the view that we now have these laws for 4 years. And what’s going to actually damage the crew is just not whether or not we win in Bahrain, however whether or not or not we will develop inside these laws over the subsequent seasons.
“That was the factor that frightened us was: if we can not develop issues within the manufacturing unit, make them, deliver them to the monitor, see them work, then the very foreign money that we take care of, by way of efficiency turns into worthless.
“That, at occasions, was fairly terrifying.”
