A new rumor suggests that the legendary Shelby GT500 Mustang is headed for production in the near future. The rumor can be traced back to a now-deleted post on the r/Mustang Reddit page that shows what looks to be a leaked United Auto Workers internal memo.

A document that appears to come from the UAW's Dearborn contingent is brimming with excitement over a new engine and where it will find a home.

A document purportedly from the United Auto Workers union claims the GT500 will return for 2026, packing an engine called 'Legend.'

A leaked memo from Ford's Dearborn Engine Plant says to expect a staffing increase this fall for the upcoming GT500's new mill.

While any purported document should be taken with a grain of salt, one recently surfaced on Reddit and was allegedly from UAW Local 600, which is based out of Dearborn, Michigan. Its members work at the Dearborn Engine Plant, Dearborn Stamping, and the Dearborn Truck Plant.
