The 2025 Ford Mustang GTD is unlike anything that’s ever worn the Mustang badge. With an MSRP of $300K, it’s not just the most expensive Mustang ever—it’s also the most technically advanced. Under the hood? A supercharged 5.2L V8 pumping out 815 HP and 664 lb-ft of torque. But power is just the beginning. A rear-mounted 8-speed dual-clutch transaxle, semi-active suspension, carbon fiber body panels, and an active rear wing push this beast closer to supercar territory than any pony car before it.
