2026 Ford Shelby GT500: The Last Great V8 Muscle Car?

A new Ford Shelby Mustang GT500 is on the way for the 2026 model year, according to a leaked UAW memo obtained by the Detroit Free Press. The document, first posted on the Mustang7G forum, reveals that Ford’s Dearborn Engine Plant is preparing to produce an all-new “Legend” engine, fueling speculation about what could be the last pure V8 Shelby GT500.

What’s happening

• The UAW memo confirms that Ford’s Dearborn Engine Plant will build the Legend engine for the next GT500 (Detroit Free Press)
• Ford recently hired 300 additional workers to support increased engine production, including for the Mustang GT500.
• The 2026 Shelby GT500 will succeed the 2020 model, which featured a supercharged 5.2L V8 producing 760 horsepower.

Why it matters

With the industry shifting toward electric performance cars, this GT500 could be the last gas-powered Shelby. The Dodge Charger Daytona EV is already moving muscle cars into an electrified era, and Ford’s own Mustang Mach-E GT signals change. If the Legend engine is truly pure internal combustion, this GT500 could be a collector’s dream.

If this is truly the final non-electrified Shelby GT500, expect massive demand from collectors and enthusiasts looking to own a piece of Mustang history. Whether it’s a full-throttle farewell or the beginning of a hybrid evolution, the Legend engine is set to redefine the future of muscle cars—one last time.
