Ford’s One‑Off Mustang V-10 Roars to Life on the Dyno, Delivering 510 HP at the Wheels
Ford revived a rare one-off New Edge Mustang prototype that used a purpose-built 5.8-liter V-10 grafted onto a 4.6-liter V8. After years in storage, Ford’s heritage team fired it up in 2026 and put it on a dyno, delivering about 510 horsepower at the wheels (well over 550 hp at the crank) with a raw, mechanical roar. The project highlights the people and stories behind preservation rather than pursuing a production car.
