The future of vehicle design follows a clear principle: less effort, greater impact. Frugal design is becoming the guiding philosophy and plastics its most important enabler. Few other materials combine design freedom, functional integration, and resource efficiency so consistently.

Reduction as a new design philosophy

Frugal design makes optimal use of every material property. At the same time, components take on multiple functions. Through the use of plastics, load-bearing structure, surface, acoustics, fastening systems, and design can be integrated into a single element – often in one production step. The result: fewer parts, less assembly, less weight.

That reduction has become a core principle in major design departments. Audi illustrated this approach with its Concept C, presented in 2025. “Radical simplicity is at the heart of our approach. We achieve clarity by reducing everything to the essentials,” said Massimo Frascella, Chief Creative Officer of Audi, during the presentation in Milan.

Here, reduction is not a limitation but a design principle enabled by innovative materials.

Form follows material

In modern vehicle design, everything begins with the material. Plastics expand the possibilities for both design and function: organic body surfaces, flowing transitions, and integrated lighting and sensor areas emerge directly from the material itself.

New polymer-based lightweight structures now achieve densities below 1.0 g/cm³ – so light that individual body components can float on water.

Thinner, stronger structures and flexible geometries are reshaping the fundamental logic of vehicle architecture: cars become flatter, more fluid and almost sculpted from a single piece.

The interior becomes a surface

Plastics are also redefining the limits of what is possible inside vehicles. Modern polycarbonates enable seamless 3D displays, touch surfaces and ambient lighting within a single moulded component.

Displays, controls and lighting are moving away from traditional device-based concepts. The interior becomes a calm, intuitive and multisensory surface where technology is integrated into the material itself.

Studies show that clearly designed, context-sensitive vehicle interfaces in automated driving scenarios can enhance trust, orientation and comfort by actively involving users and reducing uncertainty.

When material thinks

Frugal design is followed by another qualitative leap: intelligent materiality.

Plastics are no longer limited to providing form and reducing weight. They are becoming adaptive, interactive and connected.

Surfaces can integrate lighting, sensors and acoustics directly into the material. Components can indicate status, respond to use or be adjusted through software.

These “smart materials” – materials with sensing and actuation capabilities – are increasingly being researched for future mobility applications.

Circularity becomes a design criterion

Sustainability is becoming part of vehicle form itself, not just a question of material selection.

New recycling technologies enable high-performance plastics to be reused multiple times and incorporated into new designs without loss of quality.

Market analyses forecast strong growth for recycled and bio-based plastics in automotive manufacturing through 2035.

BMW is advancing this approach through its Additive Manufacturing Campus, where production waste and obsolete 3D-printed components are processed into new material.

“The use of reclaimed powder and end-of-life 3D-printed parts is a key element of a functioning and efficient circular economy,” says Paul Victor Osswald, Project Manager for Advanced Plastics Development at BMW Group.

The future of mobility is lightweight and multifunctional

The vehicles of the future will be reduced, lightweight, multifunctional and sustainable. Their design will integrate multiple functions into holistic concepts while emphasising the relationship between driver and automobile.

Plastics are a key material in this transformation – they integrate, shape and make this new vehicle logic visible.
