AAT (United States) - AllCarIndex

Advanced Automotive Technologies (AAT) was a U.S. specialty coachbuilder and prototype studio based in Rochester Hills, Michigan. Founded in 1988 by former GM designer Steve Pasteiner, it operated as a low-volume constructor of custom bodies and concept cars while offering contract design and prototyping services. AAT was best known for the 1953/2003 Commemorative Edition Corvette, a limited-production conversion launched in the early 2000s on the C5 Corvette platform. Conceived by Pasteiner in collaboration with designer Bill Miller, the conversion replaced exterior panels with new composites that evoked the 1953 C1 while retaining modern mechanicals; AAT emphasized that the transformation used factory mounting points and required no structural changes. Contemporary reports and auction records cited production targets in the low hundreds and documented completed cars, including 50th Anniversary–themed examples. The firm also developed a Nomad-inspired “Commemorative Edition Wagon” concept and undertook one-off projects. While AAT remained active as a design/prototype shop beyond the 2000s.
