The official FIA paperwork detailing the System 1 upgrades for the Spanish Grand Prix raised intrigue on Friday when Mercedes was proven to have introduced no adjustments to its automobile.
With the subsequent European part of the season kicking off as a part of a essential run of 5 races in six weeks, Mercedes had been anticipated to be on the entrance foot for Barcelona by way of adjustments.
Certainly, Mercedes workforce principal Toto Wolff had brazenly talked after the Canadian Grand Prix about there being new elements on board for this race.
“Directionally we appear to be including efficiency each weekend and we have now new stuff coming additionally, new elements coming in Barcelona that ought to assist us,” he mentioned. “So, I’d very a lot hope that we will proceed this constructive trajectory.”
As subsequently revealed by Motorsport.com, the principle aspect of this improve bundle for Spain was a brand new ground, which is among the most important efficiency parts of present F1 vehicles.
Usually, the arrival of recent elements could be formally notified to rival groups and the media on Friday morning, when the FIA publishes what’s formally referred to as ‘Automotive Presentation Submissions’.

This types a part of the requirement of Article 19.1 c) of F1’s Sporting Rules which states: “Every competitor should present a abstract doc to the Media Delegate itemizing the identify and temporary description of all main aerodynamic and bodywork parts and assemblies that haven’t been run at a earlier Competitors or TCC (testing of present vehicles) and are supposed to be run on the Competitors.”
So, the absence of the brand new ground on the Mercedes submission for Spain pointed to the German producer having maybe hit a snag and delayed the introduction of its new half.
That isn’t the case, nonetheless, with the workforce really going forward with its new ground.
So how might Mercedes introduce its new ground however not must notify the FIA of it? The solutions lie within the specifics of what Mercedes has modified with the ground, and what the principles demand.
The necessities of Article 19.1 relate solely to new ‘aerodynamic and bodywork’ parts – so in impact something that has modified form or been modified in a brand new approach.
The brand new ground that Mercedes has launched is definitely a change not in its profile, however purely in weight – as it’s merely a lighter model of what has been used up till now.
So, from an aerodynamic perspective, and from the perspective of the principles, it’s formally an identical. That is why the FIA didn’t have to be notified.
From Mercedes’ perspective, nonetheless, a weight-saving achieve in such a low space of the automobile ought to carry a efficiency uplift – particularly at an aero and car-dynamic essential monitor like Barcelona.
