Known internally as the S650E, prototypes of a hybrid Mustang have been spotted in testing—including mules entering the Technology Prove-Out phase. Though details remain scarce, it’s unclear whether this will be a traditional hybrid or plug-in hybrid, or what powertrain it might use. Speculation points towards options ranging from the electrified EcoBoost engine—the same technology already used in the Ranger PHEV—to a hybridized V8 for purists craving that classic Mustang roar.
Ford has previously stated its ambition to add hybrid powertrain options to all models in the Blue Oval’s internal combustion engine lineup by 2030, and the Mustang naturally falls under this umbrella.
Ford CEO Jim Farley has hinted that while an all-electric Mustang is unlikely anytime soon, a “partially electrified” Mustang coupe could be a compelling performance car. Farley emphasizes the importance of maintaining the Mustang’s famously American character, sound, and feel, even as it evolves.
Challenges remain, particularly balancing the weight and complexity that hybrid systems can add and the need for exhilarating performance and traditional muscle car appeal. Yet industry insiders and fans alike are optimistic that an AWD hybrid Mustang with strong fuel economy and over 500 hp isn’t just wishful thinking.
For those waiting to see what comes after the current S650 Mustang generation, reports suggest a facelift in 2026 and a next-gen model in 2029 that could incorporate electrified variants.
Ford’s hybrid Mustang, once little more than a headline, now looks like one of the most anticipated announcements in muscle car territory. The blend of performance, efficiency, and heritage could well bring the Mustang firmly into the electrified future without losing its soul. The only question left: how much longer can Ford hold off?
