Current industry standards for leather content of an automotive leather interior vary depending on the manufacturer. Most automakers utilize a combination of leather and matching vinyl in their factory leather interiors.
Traditionally, automotive leather interiors were compiled from nearly 100% leather or 100% vinyl, mainly because the look, texture, and feel of vinyl did not match well with automotive-grade leather. But as vinyl production technology progressed, automotive vinyl started to look and feel like leather and could be reproduced with a fairly accurate leather-like grain.
New vinyl could now be paired with automotive-grade leather to make vehicle interiors more economical while offering a luxurious look and feel. Automobile manufacturers started utilizing vinyl in areas of an interior, or seat, that were not considered suitable to sit on or where passengers didn’t touch often.
This trend rose as automotive manufacturers realized a growing demand for affordable, premium model vehicles. Car companies began to add more vinyl to their leather interiors, typically starting with the rear bench, while some also added vinyl to the front seats. You can typically identify these interiors when a manufacturer advertises a vehicle as being equipped with “leather-appointed” or “leather-trimmed” seats.
