Volkswagen is making the all-electric ID. family even more sustainable – including the choice of materials for the interior. During the course of this year, the ID.3, ID.4, ID.5 and ID.7 will receive selected innovations that were first used in mass production in the ID. Buzz. As one example of this, VW uses Seaqual® yarn as a seat cover material. This is made from 10 per cent collected marine debris and 90 per cent recycled PES yarn. The CO2 emissions from production are almost one third lower than for conventional cover materials.
