The folks at Hennessey Performance Engineering never rest. The company has just added a second 6×6 truck to its portfolio of bonkers, extreme off-road vehicles, and this one is based on the 2019 Chevrolet Silverado Trail Boss.
“We are very excited to offer our new Goliath 6×6 alongside our Velociraptor 6×6, truck,” says Hennessey Performance Founder and CEO John Hennessey. “These are very exclusive and unique vehicles that make a huge statement anywhere our clients go – whether its Rodeo drive or the sand dunes of the Sahara Desert.”
Like the Ford F-150 Raptor-based Velociraptor 6×6 before it, the new Goliath 6×6 rocks three driven axles for maximum off-road traction, with a custom box to accommodate all four rear wheels. The rear suspension has been completely redesigned around the truck’s extra axle, and it rolls on a set of six 20-inch Hennessey wheels with 37-inch BFGoodrich off-road tires. The truck sits higher than the standard 2019 Chevrolet Silverado Trail Boss on which its based, too, with a Hennessey eight-inch lift kit installed.
Of course, Hennessey Performance is never one to leave a factory vehicle’s powerplant untouched, and the all-new Goliath 6×6 is no different. The truck’s 6.2-liter V8 EcoTec3 L86 engine is fitted with a 2.9-liter supercharger system in this application, providing 7 psi of boost for peak output figures of 705 horsepower and 675 lb-ft of torque. Spent gases are expelled through a beautiful custom stainless-steel exhaust system.
Hennessey Performance says that even with the added weight of the extra axle and larger box, 0-to-60-mph times in the mid-4-second range are expected. That’s quicker than a lot of 80s supercars.
Unfortunately, all that performance doesn’t come cheap; the Hennessey Performance Goliath 6×6 will start at a whopping $375k, including the cost of the factory 2019 Chevrolet Silverado Trail Boss donor, and additional upgrades can push the price up even further. For example, the Goliath will offer a Brembo brake upgrade, custom interior, and even an optional stroker motor upgrade that pushes peak output up to 808 horsepower – the same as a 2018 Dodge Challenger SRT Demon on pump gas. In addition, supplies are limited, as Hennessey only plans to build 24 examples of the bad-ass 6×6 truck.
But really, no need to rush; at nearly $400k a pop, we don’t suspect the new Hennessey Goliath 6×6 is about to sell out all that soon.
