With the workforce open to the truth that it has gone down the flawed path with the design of its 2023 F1 automotive, it’s inevitable that essentially the most visible of modifications would be the greatest proof of it doing issues otherwise.
However amid loads of chatter about ‘ideas’ in Formulation 1, Mercedes has been keen to stress that there’s a large distinction between a shift in how a automotive appears to be like and a correct philosophical step-change.
Earlier this 12 months, Mercedes trackside engineering chief Andrew Shovlin admitted that the workforce had been responsible of linking the phrase ‘idea’ to its sidepods an excessive amount of.
“Maybe we have adopted the phrase idea to imply sidepod,” he defined.
“This automotive is an evolution of the automotive that we had final 12 months, and a whole lot of that’s tied round the place we have the aspect impression construction. So now we’re taking a look at larger departures as a result of it is evident that this hasn’t given us the efficiency that we would like.
“Saying that, there’s different areas of the automotive that we all know we have to enhance as properly. It will be very misguided to suppose if we go and put a different-looking sidepod on it, all of that hole goes to fade.
“The truth is that the overwhelming majority of that hole goes to have to return from different efficiency areas.”

As work continues for the Imola modifications, Mercedes has now provided an attention-grabbing explainer to shed some gentle on precisely what it believes an idea change is and isn’t – with it being crystal clear that issues go far past the visible appears to be like of its minimalistic sidepods.
The place the traces have maybe been blurred is that the Mercedes zeropods weren’t the essential facet of the automotive idea. As a substitute, they had been only one ingredient of an holistic philosophical strategy about the place the workforce’s downforce was delivered.
One rival workforce mentioned that it additionally evaluated the zeropod concept as a result of it might see the great potential in peak downforce ranges that might be produced from having a bigger ground space uncovered – particularly if the automotive might run extraordinarily near the bottom.
Nonetheless, this outfit backed away from the thought because it believed it might be troublesome to realize such downforce ranges in the actual world due to flooring flexing, bumpy observe surfaces and the danger of porpoising – one thing Mercedes discovered to its value in 2022.
It’s how and the place an F1 automotive produces its downforce that seems to be central to ‘idea’ ideas, relatively than the form of the sidepod that we will all see.
On this respect, final 12 months Mercedes paid the worth for chasing peak downforce by operating the automotive as low to the bottom as doable – one thing that would not be delivered due to bouncing/porpoising.
This 12 months, the workforce has gone too far the opposite manner, chasing downforce with the automotive as excessive up as doable. It shortly discovered that it hit an aerodynamic efficiency ceiling – which is what has prompted the ‘idea’ shift.

As Mercedes has now defined: “Once we speak about aero, we’re not simply speaking concerning the form of the automotive and the bodywork.
“It’s additionally about how we use the automotive, how we management the automotive, how we evolve the steadiness and set-up to work with the aero bundle. As a result of these components additionally impression the aerodynamic efficiency on observe.”
And whereas some aerodynamic efficiency does come from visible components just like the wings (entrance and rear) plus the sidepods, the largest good points are discovered by how airflow is managed beneath the automotive and thru the diffuser.
So that’s the reason modifications in that space – just like the venturi tunnel designs, the place the automotive runs in relation to the bottom, its rake and its journey platform – are way more essential than altering the form of an engine cowl or sidepod.
Mercedes added: “When bodywork or aerodynamic upgrades are dropped at a automotive, is the workforce subsequently bringing a brand new ‘automotive idea’?
“Nicely, the reply is… no. And that’s as a result of a automotive is continually altering and evolving. It’s far more than what you see.
“We might begin with theories over the very best course. Every division has an concept of what’s required, and we convey these totally different points collectively. The goal: to get a automotive that the workforce can extract the utmost quantity of efficiency from.
“From that place to begin although, it’s a continually growing image. With each step of the design, check, and manufacture course of, we’re studying. Each lap accomplished on the observe allows us to construct our understanding and our improvement.
“The results of that course of is a automotive that mixes tons of, if not 1000’s, of concepts because it strikes from preliminary launch to crossing the end line in Abu Dhabi.”
And whereas there was loads of speak of the F1 grid falling into three idea teams – the Pink Bull-style downwash resolution, the Ferrari inwash resolution and the Mercedes zeropod – issues will not be fairly so simple as that.
Certainly, the true variations between the groups are way more to do with the course they absorb chasing the right set-up and aerodynamic platform.
As Mercedes mentioned: “‘Automobile idea’ subsequently is much less about what you see bodily on observe. It’s the speculation and understanding of what all the weather are to supply the quickest doable automotive. And that is all the time a shifting goal.
“We don’t merely begin off with an idea and that’s it. The sport is to study as a lot as doable, sooner, and in additional depth than our rivals.”
So, when Mercedes takes to the observe at Imola with its new sidepods, it’s going to mark not the ultimate reply to its change of idea however extra step one in the direction of what it hopes will ultimately be a race-winning automotive.
