Based on a Chevy Silverado Trail Boss and powered by a 6.2L V8 engine fitted with a 2.9L supercharger, the Goliath from Hennessey is a 6X6 custom monstrosity. It got an 8-inch lift over the factory model as well as a custom interior, custom bumpers and rollbar, LED lighting, & it rides on six 20” Hennessey wheels. An upgraded stainless steel exhaust cranks the horsepower up to 705 with 675 lb. ft. of torque, for when too much is never enough.
