Mercedes says the W13 wouldn’t have passed FIA’s bouncing test in Baku

Mercedes’ Technical Director Mike Elliott says he is not sure what will happen to the cars who don’t pass the FIA’s bouncing test, but adds that Mercedes was within allowed limits at Silverstone.

The FIA’s ‘anti-porpoising’ Technical Directive will begin to be enforced at the Belgian Grand Prix.

Mike Elliott says Mercedes’ car is now within limits of the maximum allowed level of vertical oscillations, according to the FIA’s Aerodynamic Oscillation Metric (AOM).

“Going back over a few races using that metric, Baku is one we wouldn’t have passed,” Elliott explained.

“But if you look at where we were at Silverstone, we wouldn’t have even triggered the metric.

“It is going to be interesting to see how it is applied and how it is used through the season, because none of us wants to be bouncing. We’re not trying to develop into that position.”

Red Bull team boss Christian Horner has suggested that the cars that do not pass the FIA’s test should not be allowed to run, but Elliot is not sure this is the right way to proceed.

“The question becomes, if you are exceeding the metric, can you actually fix it during a race weekend?

“I don’t think any of us want to see cars not taking parts and cars thrown out, because they’re not able to get on top of those issues.

“I think time will tell whether that metric can be done in the right way, or whether that can sort of push things in the right way without ending up damaging the show.

“We’ll see what happens. I’m sure the FIA are conscious of it.”

While Mercedes has seemingly solved their bouncing issue, Elliott says the phenomenon could re-emerge at the Hungaroring.

“Certainly the last few circuits where we have seen quite a lot of bouncing, I think it is just because the circuits are quite bumpy and with very stiff cars.

“I think when you look forward to say Budapest, it might be challenging for teams for the same reason.

“But at the same time, I think we’re all getting on top of our issues. We’re understanding those issues and developing the cars.

“So hopefully, we can sort of move away from that,” the Briton concluded.
