Last summer, Ford unveiled the GT ’67 Heritage Edition at the Monterey Car Week, paying homage to their 24 Hours of Le Mans win in 1967.

The supercar sports a Race Red finish on the outside, contrasted by white stripes that run across its length.

Other details are the special graphics on the hood and doors, 20-inch forged aluminum rims and an exposed carbon fiber package to further distinguish it from the rest of the second-gen GT family.

One of the clients that took delivery of the Ford GT Heritage Edition is John Hennessey. The owner of Hennessey Performance hasn’t messed around with the exotic model so far, but he has subjected it to one special test.

The Ford GT was strapped to a dyno in an attempt to find out just how powerful it is. And the video that follows below answers this exact question.

Officially, the twin-turbo 3.5-liter EcoBoost V6 churns out 647 hp (656 PS / 482 kW) and 550 lb-ft (745 Nm) of torque at the crank – the same as the non-Heritage Edition GT. Under full throttle, the new GT accelerates to 60 mph (96 km/h) in less than 3 seconds, and goes up to a top speed of 216 mph (348 km/h). So, let’s see just how much power that V6 produces in the real world, as per Hennessey’s dyno run.
