Enthusiasts of American muscle cars have reason to celebrate as whispers of a new Ford Shelby Mustang GT500 are gaining traction. A leaked document from the United Auto Workers (UAW) union, corroborated by a source close to the program, suggests that a 2026 model year GT500 is indeed in the works, promising to inject fresh adrenaline into the iconic Mustang lineup.
According to a memo from UAW Local 600, initially reported by the Mustang7G forum, Ford’s Dearborn Engine Plant is ramping up its operations. Around 300 new employees have been brought in to bolster engine production, primarily for models like the Bronco Sport SUV and Maverick pickup. However, the memo reveals a particularly exciting detail: a dedicated shift on the Niche Assembly line is slated to commence later this year to produce an engine, codenamed “Legend,” specifically for the 2026 Mustang Shelby GT500.

While Ford remains tight-lipped about future product plans, with spokesman Mike Levine declining to comment on the GT500 speculation, the UAW memo and insider confirmation provide compelling evidence that the high-performance Mustang variant is making a comeback. The “Legend” engine moniker is already sparking intrigue among automotive aficionados, hinting at potentially groundbreaking power and performance figures.
The previous generation Shelby GT500, a 2020 model, set a high bar with its supercharged 5.2-liter V8 engine delivering a staggering 760 horsepower. As reported by Edmunds, the demand for these models remains strong in the used car market, with prices ranging from $70,000 to upwards of $117,000 for 2020-2022 models. This robust resale value underscores the enduring appeal and desirability of the Shelby GT500.
The anticipation surrounding the 2026 Ford Shelby Mustang GT500 is already building. Car enthusiasts are eager to learn more about the “Legend” engine and the performance enhancements Ford has in store for this legendary nameplate. As details emerge, the promise of a new GT500 reaffirms Ford’s commitment to high-performance vehicles and the enduring legacy of the Mustang Shelby.
