The art of the steal: Why copying is a technical necessity at McLaren

In the quiet, clinical corridors of the McLaren Technology Centre, the race for the next millisecond never truly stops.

While the public focus remains fixed on the gladiatorial battles on track, a more cerebral, shadow-filled war is being waged behind computer monitors and within wind tunnels.

It is a world where photography is a weapon and a Formula 1 rival’s breakthrough is simply a blueprint for the rest of the grid.

McLaren Chief Designer Rob Marshall recently provided a rare, unvarnished look into this culture of mimicry, explaining that the pursuit of performance often requires looking outward just as much as looking inward.

In a sport where being unique is a secondary goal to being fast, the line between inspiration and imitation is razor-thin.

The anatomy of analysis

The process of deconstructing a rival's car is far more rigorous than simple observation. It involves a systematic filtration system that determines what is worth pursuing and what is physically impossible to integrate.

According to Marshall, the team leaves no stone unturned when a competitor finds a new way to manipulate the air.

“We look at everything; some things are closed off to use quite quickly when you look at the regulations, but others remain open,” Marshall confirmed.

This initial triage is only the beginning. The technical limitations of a car’s existing bones often dictate how much of a rival’s genius can actually be stolen.

“Others are kind of limited by architectural changes you may have made, or what you do with the engine, but ultimately, we analyse everything," Marshall continued.

"Some things go as far as being wind-tunnel, or CFD tested, and others are kind of thought experiments we do to see whether it would be good or bad for us.

“But the bottom line is that we look at pretty much everything the opposition does up and down the grid and try to assess whether those things would work on our car.”

Debunking the myth of originality

There is a long-standing romanticism in the paddock that suggests a car must be a cohesive, original thought to be successful. Engineers often claim that parts are so interconnected that you cannot simply "bolt on" a piece of a rival's aerodynamic kit.

Marshall, however, is quick to challenge that conventional wisdom.

“There is a common phrase in F1 that copying stuff doesn’t work, what works on one car won’t work on another, but that’s not necessarily true,” he noted.

To prove his point, he pointed back to 2009, when Brawn GP’s controversial double diffuser revolutionized the sport overnight, forcing the entire field into a frantic game of catch-up.

“The double diffuser worked on one car, and everyone copied it, so copying is just a part of F1,” he said.

The intellectual property trap

However, Marshall warns that a "photocopy" approach is rarely enough. The real challenge isn't just seeing what a rival has done, but reverse-engineering the "why" behind it.

Without that deeper understanding, a copied part is a dead end for future development.

“There is one thing in copying others, actually trying to understand what is going on, what the other team is trying to achieve, and that’s where the real trick of it is, because you can copy someone but don’t have their understanding,” Marshall explained.

The goal for the McLaren design team is to bridge that gap. If they can replicate the logic, they can replicate – and eventually exceed – the performance.

“If you research it properly, hopefully, you will develop the same sort of background IP, so it is a nod to the other teams," Marshall added.

In the end, Marshall views the technical arms race as a mix of high-level physics and human instinct.

“It’s just a part of F1, some things you think of yourself, and you’re proud of those, then the stuff you copy, and other things you just develop or invent in the bath, and no-one wants to copy that,” he concluded.

While some might see copying as unsporting, in the eyes of a chief designer, it is a survival mechanism.

In the relentless pursuit of the podium, pride is a luxury, and understanding the brilliance of your enemy is the surest way to beat them.
