Trends and needs in the automotive industry are always changing and evolving. They require constant R&D and often adaptation / commercialization of new technologies.  Better gas mileage, extended range for EVs, and faster acceleration are heavily dependent on weight savings from advanced materials that were once limited to high performance race cars or the aerospace & defence sector.  New paint aesthetics that are more robust than ever before have been developed to meet the demand for cars that look more modern and can be kept on the road longer.  Even the foam used for seating and sound isolation continues to be refined to offer a more comfortable and quieter ride.
