LESS THAN a year since American tuner Hennessey first announced it will be building a 6×6 beast based on the 2019 Chevrolet Silverado, the company has rolled out its first production Hennessey Goliath 6×6.

Plenty was done by Hennessey to turn a standard Silverado Z71 into the aptly named 6×6 pick-up truck. Aside from the new custom truck bed that stretches over the additional rear axle, the Goliath towers high on an eight-inch lift kit and rides on 20-inch wheels wrapped in BFG off-road tyres.

Despite its increased girth, this particular Goliath, which is earmarked for the “owner of the largest potato farm in Wisconsin”, only comes with Hennessey’s ‘450bhp engine upgrade’, which consists of a cold air intake and stainless steel exhaust fitted to the original Silverado’s 420bhp (313kW) 6.2-litre LS V8.

Being the same tuner that gave the world the Ford F-150-based 800bhp (597kW) Hennessey VelociRaptor 6×6 and the 1000bhp (746kW) Exorcist Camaro, there are higher power tuning options available, including a supercharger and stroker engine kit to raise power to 597kW.

Other upgrade options Hennessey offers includes the fitment of Brembo brakes, as well as a custom interior upgrade.

Hennessey will only build 24 examples of the Goliath and will export to buyers in international markets, with prices starting at an equally large USD$375,000 before options; though that price does include the Silverado donor truck.
