Commercial vehicles have one key difference from passenger cars. They are a tool to do work and are, therefore, specified and built with a certain application in mind, which is often referred to as the duty cycle. Maintenance of the commercial vehicle is necessary, yet downtime to fix the vehicle is highly undesirable. In many cases, a fleet will test a product for a year before they are confident that the product is ready for its fleet of vehicles. So, the material selection on commercial vehicles must include durability and maintenance as considerations.
