The J.D. Power U.S. Manufacturer Website Evaluation Study is a semi-annual study that measures customer satisfaction with automotive manufacturer websites while shopping for a new vehicle by examining five key measures (order of importance): visual appeal; navigation; speed; vehicle research; and research tools.

The U.S. Manufacturer Website Evaluation Study, initially released in 1999, is based on responses from 11,181 new-vehicle shoppers who indicated they will be in the market for a new vehicle within the next 12 months. The study was fielded in October-November 2025.
