Since its founding in 1991, the Sealy, Texas-based automotive tuning house Hennessey Performance (HPE) has modified and optimized more than 10,000 high-performance sports cars, trucks, and SUVs from brands that range from Porsche and Ferrari to Jeep and GMC. For its latest release, HPE has tackled the new 2019 Chevrolet Silverado Trail Boss.

The most obvious addition to this bespoke vehicle is evident in its name; the Hennessey Goliath 6X6 adds a second rear axle for a grand total of six drive chain-connected wheels. An absolute beast of a truck, it’s two feet longer than the standard Chevrolet Silverado Trail Boss and rests on massive 20-inch tires.

With a supercharged 6.2-liter V8 engine that can produce 705 horsepower and 675 foot-pounds of torque, the Hennessey Goliath 6X6 offers virtually endless off-road capabilities. And it’s also quick on the road, going from 0 to 60 miles per hour in approximately 4 seconds.
