If you ever wanted to see the massive Hennessey Performance Silverado Goliath 6x6 in action, this video should scratch that itch.
Pickup trucks are getting bigger and bigger in North America. What used to be a full-size pickup is now considered a mid-size. What was a heavy-duty pickup is now a full-size one. Heavy-duty pickups are now verging on commercial dump truck territory. So it’s only natural for Hennessey to take this pattern to its logical conclusion and build what might be the largest pickup truck you can legally drive on the road.
It’s called the Hennessey Goliath 6x6. It started life as a humble 2019 Chevrolet Silverado Trail Boss with the Z71 package and an extended cab, but then sprouted an extra axle and grew a 2.9-L supercharger on its 6.2-L EcoTec3 V8 engine.
Total horsepower is 705 hp, while torque is measured at 675 lb-ft.
But the real show is in the back, not the front. The bed has been extended to provide space for an entirely new driven axle, along with wheels, tires, suspension, and even brakes. An overall 8-inch lift provides space for the new 20-inch wheels and 37-inch BF Goodrich off-road tires, but even with the enormous rubber in the way you can still see where the chassis has been extended by a couple of feet.
A new front and rear bumper combine with new head and tail lights to give the Goliath a distinct look--if that wasn't already accomplished by the extra axle. Brembo brakes are an optional extra, as is a custom interior and a stroker motor that ups the power to 808 horses.
As you can see in the video, the Goliath is a massive beast, but it also seems surprisingly smooth cruising around Hennessey’s test track. Perhaps that’s to be expected given the enormous suspension and extended cab. No off-roading is performed, but we’re still convinced that this thing can crawl over whatever terrain it wants, including other cars.
Production is limited to 24 units with a few already having been delivered to eager customers. Sticker price is $375,000, but that also includes the cost of the original truck. This thing is already the size of a house, so it might as well cost the same too.
