It's not even close.
Ford didn't exactly pull any punches when it came to the second-generation Ford GT supercar.
It's a machine that was built with a singular purpose: to commemorate Ford's historic 1966 win at the 24 Hours of Le Mans with a class victory at the very same race, exactly five decades later. Producing a car capable of such a feat meant throwing everything but the kitchen sink at it: a lightweight carbon-fiber monocoque, the most advanced aerodynamics Ford has managed to-date, and a race-honed twin-turbocharged EcoBoost V6. Who needs eight cylinders when you've got boost?
The Ford GT is, simply put, no slouch. But neither is Ken Block's mega-powerful Hoonicorn RTR Mustang.
In case you're not acquainted, the Hoonicorn RTR is a 1965 Ford Mustang notchback with a gargantuan 6.65-liter Roush Yates racing V8 under the hood, fed by a pair of turbochargers and a methanol-injection system. The result is a colossal total of 1,400 horsepower, sent to all four wheels through a six-speed sequential transmission. The car made its debut at the 2014 SEMA Show in Las Vegas, alongside the debut of the film in which it first starred: Gymkhana 7.
Granted, at its debut, the Hoonicorn was naturally aspirated, having just 845 horsepower to its name. The extra power didn't come until a few years later, as Block was getting ready to film Climbkhana. But both figures are appreciably greater than 647, which is the horsepower the Ford GT left the factory with.
The cars are about dead even in the weight department, while the GT obviously has the advantage with regard to shifting speed and number of forward gears - not to mention gearing. Of course, neither is anything close to a purpose-built drag racing machine, but the Hoonicorn has already left its mark, dispatching cars like the McLaren Senna, the "world's fastest donk," a heavily modified Audi RS3, and others in weeks past. Not too bad for what is effectively a short-geared stunt car.
