The Hennessey GOLIATH 700 GMC Sierra AT4 blends premium refinement with serious off-road performance, creating a truck engineered for drivers who want luxury without sacrificing capability.

Built around GMC’s upscale AT4 platform, the GOLIATH 700 upgrade adds a high-performance supercharger system to the 6.2L V8, delivering 700 horsepower along with stronger acceleration, sharper throttle response, and unmistakable Hennessey attitude.

In this video, we take a closer look at what separates the GOLIATH 700 AT4 from everything else on the road—from its aggressive stance and off-road capability to the elevated interior and commanding presence that define the Sierra platform. The result is a truck equally comfortable pulling up to a high-end resort, crossing rough terrain, or stretching its legs on an open Texas highway.

Like every Hennessey build, the GOLIATH 700 is engineered to deliver real-world performance with factory-level drivability and durability. It’s luxury off-road performance without compromise—built for customers who expect more from their truck in every environment.
