Talked to Weathertech earlier to ask if the front and back row of the nice fit liners they have would support the refresh 2021 Model S. The website notes a do not fit but the product team let me know that what they are shipping now does fit and sent me a couple of their quality approval photos. The front seats are the same in the new S, but the back seat is slightly different - and these seem to fit well. Ordered some and definitely better than the other regular rubber WT mats branded with Tesla on their site for now.
