What are the most common material selection challenges for automotive interiors?

2 Safety and compliance

Another challenge for automotive interior materials is to meet the safety and compliance standards and regulations of different markets and regions. Materials need to comply with the requirements for flammability, toxicity, emission, recyclability, and biodegradability, among others. Designers need to be aware of the current and future legislation and certification processes, as well as the potential risks and liabilities of the materials. Some of the solutions to improve safety and compliance include using fire-retardant, low-VOC, bio-based, or recycled materials, or adopting innovative technologies such as smart sensors, airbags, or seatbelts.

3 Comfort and ergonomics

A third challenge for automotive interior materials is to provide comfort and ergonomics for the occupants. Materials need to offer adequate cushioning, support, ventilation, acoustics, and tactile feedback for the seats, armrests, headrests, steering wheel, dashboard, and other touchpoints. Designers need to consider the preferences and needs of different users, such as age, gender, height, weight, posture, health, or disability. Some of the solutions to enhance comfort and ergonomics include using adaptive, breathable, sound-absorbing, or textured materials, or incorporating features such as heating, cooling, massage, or lumbar support.

4 Aesthetics and identity

A fourth challenge for automotive interior materials is to create aesthetics and identity that reflect the brand, style, and personality of the vehicle and the owner. Materials need to convey the desired attributes, such as luxury, sportiness, elegance, or innovation, through their color, texture, pattern, finish, or shape. Designers need to balance the visual appeal and the functionality of the materials, as well as the coherence and harmony of the overall interior design. Some of the solutions to create aesthetics and identity include using natural, synthetic, or hybrid materials, or applying techniques such as embossing, stitching, or printing.

5 Cost and availability

A fifth challenge for automotive interior materials is to manage the cost and availability of the materials in relation to the demand and supply. Materials need to fit the budget and the quality expectations of the manufacturer and the customer, as well as the production and distribution processes. Designers need to evaluate the cost-benefit ratio and the return on investment of the materials, as well as the potential fluctuations and shortages of the materials. Some of the solutions to optimize cost and availability include using local, renewable, or alternative materials, or leveraging economies of scale, mass customization, or modular design.

6 Innovation and sustainability

A sixth challenge for automotive interior materials is to foster innovation and sustainability in the industry and the society. Materials need to offer new and improved functionalities, experiences, and values for the vehicle and the user, as well as reduce the environmental and social impacts of the vehicle lifecycle. Designers need to embrace the principles and practices of circular design, biomimicry, cradle-to-cradle, or design for disassembly, among others. Some of the solutions to drive innovation and sustainability include using smart, responsive, or biodegradable materials, or collaborating with multidisciplinary teams, stakeholders, or communities.
