These systems can improve fuel economy by 3-5 percent, depending on the driving habits of the customer. For your shop, it is essential to understand what is different on these vehicles, and how those differences might change your diagnostic approach.

Customers soon began complaining about wind noise and chassis vibrations in ’60s-era cars. Back then, these complaints weren’t repairable because good NVH abatement technology had yet to be developed. Today, that is not the case.
