The internal material of the new steering wheel is also made of aluminium alloy. A non-alloy aluminium would not be sufficiently durable and, with the force applied during driving, would result in the deformation of the steering wheel. There are many options for the lining: natural materials such as suede; Alcantara (a synthetic microfiber that is rather expensive, especially because it is a registered trademark); synthetic products such as PVC (more resistant to chemical and atmospheric agents) and coated polyurethane, which offer a huge variety of choices and are the most widely used nowadays. The choice of patterns is also broad and includes imitation carbon, for example.
