Hennessey Bosses the Trails with 808-hp Chevy Goliath 6×6
Hennessey Performane has introduced a new boss of the trails, the Hennessey Goliath 6×6. Based on an all-new 2019 Chevrolet Silverado Trail Boxx Z71 pickup truck, the Goliath adds another axle and a lot more power. Plus a six-figure price tag.
The conversion truck is a 6×6 (three wheels on each side), with power pushing all three axles. The rear suspension system is upgraded to match the dual axles and an 8-inch (20-cm) lift kit has been added for higher clearance. The truck’s bed is, obviously, customized to match the extra axle and higher number of tires, while Hennessey-exclusive 20-inch wheels have been added to carry those BFG 37-inch off-road tires.
Several other touches, such as a rollbar upgrade, Hennessey-made front and rear bumpers, LED lighting, plus Goliath 6×6 and Hennessey graphics are also included on the truck.
The 6×6 chassis means there are six wheels being powered all at the same time on the Hennessey Goliath 6×6
Under the hood, Hennessey took the 6.2-liter eight-cylinder engine Chevrolet normally offers for the Silverado and boosted power with an HPE700 Supercharger. That 2.9-liter supercharger pushes 7 psi of air boosting into the engine, pushing power to 705 horsepower (526 kW) at 6,200 rpm and 675 pound-feet (915 Nm) of torque at 4,200 rpm. Hennessey expects that the upgrades will mean 0-60 mph (92 km/h) times of about 4.5 seconds despite the added weight on the truck.
The base price for the Goliath 6×6 will be US$375,000, which will include the price of the 2019 Chevrolet Silverado it’s based upon. That’s slightly cheaper than the Ford-based VelociRaptor 6×6 introduced a couple of years ago. A few upgrades, like an 808 bhp stroker motor add-on, Brembo brakes, and custom interior options will also be available. Production will be limited to 24 units, and the vehicle will be available for export.
Besides the extra axle, the rollbar, Hennessey graphics and logos, some interior elements on the Goliath 6×6 are also custom
Most engine boosting comes from Hennessey’s own in-house supercharger, the HPE700, made to fit the 6.2L V8 on the Goliath 6×6
