When motorsport demands more from materials, should engineers demand more from material knowledge?

Kasia Price, our Technical & Quality Director poses a few questions ahead of this year’s Motorsport Technology Expo.

Formula 1, and motorsport in general, has always been defined by engineers prepared to challenge accepted wisdom.

Every season pushes the boundaries a little further. Components are expected to become lighter, stronger and more durable while operating under higher temperatures, greater torque loads, increasing fatigue cycles and ever tighter manufacturing tolerances.

At the same time, engineers must satisfy increasingly demanding technical regulations, sustainability objectives and relentless commercial pressures.

Take a look at the evolution of F1 lap times from 1960 to 2020 and the time gap improvements are astonishing. And now consider the new challenges posed by F1’s new design regulations which bring a new engine formula and aerodynamics into the equation. It’s no longer just about speed but control.

The F1's new 2026 regulations explained.

In many respects, modern motorsport is now asking materials to perform in ways their original designers could never have envisaged. Yet while engineering ambition continues to evolve at remarkable speed, an equally important question is beginning to emerge.

As motorsport demands more from materials, should engineers now be demanding more from material knowledge?

Motorsport history provides countless examples of challenging norms and questioning the status quo. When John Barnard developed the McLaren MP4/1, aluminium, the accepted material of the era, could no longer deliver the stiffness required for his revolutionary chassis concept.

Rather than compromise the design, he challenged the material assumption itself, pioneering the carbon fibre monocoque that transformed Formula 1 engineering. It remains one of motorsport's clearest examples of how questioning accepted material thinking can unlock entirely new levels of performance.

You can explore the full development of his prototype experiments in the late 70s to the car’s debut at the Argentinian Grand Prix in 1981.

The McLaren that changed Formula 1 history

Engineering excellence begins with engineering curiosity

The most successful engineering organisations recognise that every breakthrough is temporary and that today's competitive advantage quickly becomes tomorrow's benchmark.

Progress depends upon continual learning, questioning accepted practice and having the confidence to challenge established thinking whenever new knowledge emerges. Every major engineering advance has followed that pattern.

Carbon fibre replaced aluminium because engineers questioned convention. Advances in metallurgy, remelting technologies, heat treatment, manufacturing consistency and production processes have all emerged because engineers continued asking whether better solutions already existed. Material selection deserves exactly the same mindset.

Many engineering specifications continue to perform exceptionally well, but they were developed using the material knowledge, manufacturing processes and engineering understanding available at the time.

As metallurgy continues to evolve, together with manufacturing technologies and increasingly sophisticated manufacturing routes, engineers have an opportunity to ask an increasingly important question.

If today's engineering knowledge is different, should today's material decisions also be different?

That isn't change for the sake of change. It's engineering curiosity supported by evidence, experience and technical understanding. There’s even a growing number of examples where material solutions, dare we say it, move from steel and aluminium to ground-breaking thermo-plastic material - XYcompDLFComposites developed by Green Tweed in its collaboration with Arrow McLaren.

Engineering specifications should never become engineering habits

Every engineering specification began life because someone challenged conventional thinking.

The irony is that the most successful innovations can eventually become the assumptions future engineers inherit - which is entirely understandable. Proven specifications reduce uncertainty, build confidence and establish consistency - but the real challenge is recognising when engineering knowledge has moved on.

More recently, even Formula 1's most successful teams have spoken openly about the value of questioning their own assumptions.

Oh God, how could we have been so dumb?

Reflecting on Mercedes' return to competitiveness in 2024, Technical Director James Allison described the team's breakthrough not as a "eureka" moment, but as an "Oh God, how could we have been so dumb?" realisation that the solution had been there all along - they simply hadn't recognised it sooner.

High-performance engineering demands curiosity, evidence and the confidence to revisit established thinking when new materials, manufacturing methods or metallurgical understanding create fresh opportunities.

The objective isn't to create unnecessary risk. It's to reduce it through better-informed engineering decisions.

Better engineering begins with better questions

Hillfoot has seen how engineering curiosity translates into measurable engineering outcomes.

In one particular project, a manufacturer producing a critical engine component approached the business using a long-established material specification that had consistently delivered reliable performance.

Rather than treating the specification as fixed, Hillfoot's metallurgical specialists stepped back and asked a much simpler question.

Would we make exactly the same engineering decision if we were designing this component today?

Reviewing the application, manufacturing route and performance requirements from first principles revealed an opportunity to recommend an alternative material solution that maintained the required engineering performance while reducing manufacturing costs.

The breakthrough didn't come from discovering a revolutionary new alloy. It came from challenging an established engineering assumption. Sometimes the greatest engineering gains aren't found by changing the component. They're found by changing the thinking behind it.

Better decisions begin earlier

By the time a material specification reaches procurement, many of the most important engineering decisions have already been made.

That's why earlier collaboration between design engineers, metallurgists, manufacturers and material specialists is becoming increasingly valuable.

It allows assumptions to be challenged before they become expensive, and enables alternative grades to be evaluated while design flexibility still exists. Importantly, it also creates opportunities to optimise manufacturing routes, improve consistency and reduce technical and commercial risk long before production begins.

This philosophy underpins our MetPlus engineering methodology, introducing metallurgical expertise at the earliest possible stage of the engineering process. Rather than simply supplying material against an existing specification, the objective is to help engineers make better-informed decisions before those specifications become fixed.

Motorsport's next competitive advantage may begin with a better question

Motorsport has always belonged to engineers prepared to question accepted wisdom. And a man who needs no introduction is Adrian Newey - dubbed the Einstein of Formula1 - who left Red Bull at the end of 2025.

His trailblazing career offers a simple lesson: innovation does not always depend on inventing something entirely new. It can come from applying existing technologies in a new way, interpreting regulations more sharply or rebalancing the compromises within a design until the whole car performs differently.

Innovation is not always about inventing something new. Sometimes it is about seeing more potential in what already exists.

Newey’s use of active suspension is a case in point. He did not invent the system, but he saw more in it than others did. By treating it as a platform-control tool rather than simply a suspension technology, he unlocked greater aerodynamic performance. The competitive advantage came from deeper understanding, integration and application - not ownership of the original idea.

Adrian Newey - innovator and trendsetter

If we were designing this component for the first time today, knowing everything we now know about materials, metallurgy and manufacturing... would we still make exactly the same engineering decisions?

Join the discussion and meet the Hillfoot team.

That is precisely the conversation Kasia Price and her fellow panellists will be exploring at the Motorsport Technology Expo UK taking place at the Farnborough International Exhibition and Conference Centre on 15-16 September 2026.

If you're an engineer, designer or manufacturer responsible for components that operate at the limits of performance, this isn't simply another technical discussion.

It's an opportunity to challenge assumptions, exchange ideas with fellow specialists and explore how advances in material knowledge can translate into better engineering decisions.
