If the Hennessey->ke1863 tuned-Ford F-150->ke423 VelociRaptor 500 isn't powerful enough for you, then you're in luck. Somehow, Hennessey shares the same sentiments and have thus decided to give their mountain of a truck its own big brother.

In this video, we are given the first look at the new tuned-up 6.2-liter V8 Raptor that is reported to produce over 605 horsepower and 622 lb/ft of torque. Those figures, if you didn't know, are a jump over the VelociRaptor 500's output of 501 horsepower and 520 lb/ft of torque and should lead to a significant decrease in time for the 0-60mph sprint. If you don't remember, the VelociRaptor 500 completed the 0-60mph sprint in 5.6 seconds leading us to believe the new Raptor will complete the sprint in just over 5 seconds.

In addition to the more powerful engine, Hennessey Performance also gave this beast of a truck a twin-turbo system with matching intercoolers and a stainless-steel exhaust that clearly doesn't need any explanation as to why it was put there. Hennessey also added an upgraded fuel system and boost controller because, well, with that much added power, the truck needs a little help in the respiratory department.

You want steel-breaking, mountain-crumbling power? This 6.2-liter Ford V8 VelociRaptor is just what the doctor of destruction ordered, even though we cannot possibly think of a reason why anyone would need such a speedy mountain of a truck.
