We have heard of the many creations that come out of the great factory of Hennessey Performance in the state of Texas. Combining the power of forced induction and superior off road performance, the mad scientists at Hennessey Performance have created the best of both worlds into one beast. Since 2017, the American company Hennessey Performance has been responsible for two 6x6 truck giants: the Ford VelociRaptor 6×6 and the Chevrolet Silverado Goliath 6×6. Our focus here is on the latter beast, which is based on the Chevrolet Silverado Trail Boss Z71. Hennessey only produced 24 examples of the Goliath 6x6, making it a rare behemoth to own. It is basically a Silverado on steroids with new and upgraded everything. The example shown here is a 2019 Chevrolet Silverado Hennessey Goliath 6x6 with serial number 02 and only 9,000 miles on its clock.

Exterior and Interior

A machine like the Chevrolet Hennessey Goliath 6x6 deserves a look to match its personality underneath the skin. Riding high above the ground, the gloss black exterior of our subject is accented by Silver Hennessey badging displayed around the custom 6x6 truck bed that has been made to fit the extra rear axle. Additional lettering graphics shows the ‘Goliath 6x6’ script with a hint of red. The truck rides high on a 8” Lift Kit with the help of an upgraded suspension and King Off-Road Racking Shocks. The truck is fitted with custom front and rear bumpers that feature built-in radar. Should the six-wheeled Hennessey Goliath not be impressive enough, it also has 20-inch Hennessey wheels armored with 37" BF Goodrich Mud Terrain T/A tires. Thanks to the Ride Right Suspension system, the truck's height can be electronically controlled with a remote. As you climb into the well-equipped black interior of this 2019 Chevrolet Silverado Hennessey Goliath 6x6, you can find the plaque that displays its significant serial number on the roof. The dash is packed with toggle switches, knobs, and buttons, while a touchscreen sits above. This cabin features a few wood accents and a sunroof that adds to the overall experience inside.

Engine

The Silverado’s stock 6.2-liter V-8 engine has received the HPE700 Supercharged upgrade for the Hennessey Goliath 6x6 model, with a 2.9-liter supercharger system producing seven psi of boost. 705 hp and 675 lb-ft torque are sent to the wheels via a 10-speed automatic transmission. According to Hennessey Performance, this behemoth is capable of a 0-60 mph time in the mid-4-second range despite the extra weight.
