Traditional high-performance engines are being surpassed by the race to develop superior e-battery systems for electric vehicles (EVs). This design simulation not only enables early risk mitigation, performance optimization, and cost reduction but also accelerates the part development.   For more insights into how Avient supports EV design and development, click here.

Government funding and support through various laws, tax credits, and development grants indicates that public EV charging equipment production will likely continue on a high growth trajectory. Automakers are also making significant investments, not only in the adoption of EVs but also in the development of a robust infrastructure that will support the millions of vehicles expected to be on the road within the next few years. As the demand for electric vehicle supply equipment (EVSE) rises, new options and charging station models are constantly being developed.

This provides ample time for brand owners and designers to create, develop, and introduce their products when the trends and their influences are expected to be prominent. ColorForward™ 2025 was issued in December 2023, providing ample time for brand owners and designers to create, develop, and introduce their products.  The goal of a ColorForward presentation is to inspire creativity, while informing brand owners and designers of upcoming trends that can help develop impactful aesthetics for next-gen product launches.
