General Motors announced today that GM Design chief Ed Welburn will retire effective July 1, 2016. His retirement will mark the end of an impressive 44-year career at GM, with the last 11 years serving as GM’s head designer.

Welburn’s career has led him to oversee some of GM’s most monumental designs of recent, including the 2010 Chevrolet Camaro and seventh-generation Corvette Stingray. He’s credited to spearheading GM’s transition back to focusing on design as a product differentiator during the company’s restructuring process over the last decade.

GM has already confirmed Michael Simcoe as Welburn’s replacement. Simcoe has spent the last 33-years at GM, most recently serving as vice president of design for GM’s international operations. He began his career at GM Holden in Australia and has had a lead role in many of GM’s global designs, including the recent Buick Avenir Concept.
