American tuner Hennessey now comes out with its own six-wheeled version of the all-new Chevrolet Silverado, nicknamed Hennessey Goliath 6×6.

The car began life as a Trail Boss Z71 model, but now it’s gained a third axle with an additional pair of wheels (all six run on automatic transmission), which means it also has a new suspension system as well. Hennessey says it lifted the truck by eight inches to help it course through anything that stands in its way.

You’ll find more upgrades upon closer inspection. Among them is the 6.2-liter V8 engine (same as the base vehicle) with a 2.9-liter supercharger. That’s if you want to boost the Silverado’s horsepower to 705 at 6,200 rpm and 675 pound-feet of torque at 4,200 rpm.

Outside, you’ll find that Hennessey created a grille specific to this model. In addition, there’s also a roll bar in the bed. Also, you’ll find BF Goodrich 37-inch off-road tires for the 20-inch wheels. However, there’s no information yet on whether the company did some tinkering in the interior, too.

Planning to get your hands on the Hennessey Goliath? Bear in mind that it’s not going to be easy. Production of the custom car is underway, to be sure. However, Hennessey is only making 24 examples worldwide, costing $375,000 apiece. Optionals include Brembo brakes on all three axles, a custom-designed interior, and an upgraded V8 engine. That’ll bump the horsepower to 808 if you’re mad for speed.

The best part about all this is that Hennessey’s latest handiwork is actually approved by Chevrolet, which means customers will be able to order the vehicle at participating Chevrolet dealers knowing that Chevrolet itself gave the go-ahead.
