Goliath 6x6 Is an 800 HP Chevy Silverado Monster Truck

As you probably know, the current generation Silverado truck came out in 2018. Perhaps inspired by the legendary Mercedes-AMG G 63 6x6 and its insane price, Hennessey set out to create an American version of the six-wheeled Gelandewagen.

By 2019, it had turned a regular Silverado Trail Boss Z71 into a monster by adding a third axle. The bodywork had been massively extended and customized, partly with the help of the Goliath package, which you can fit onto any regular Silverado.

One small thing that's changed since the last time we saw it is power. Hennessey started with the 6.2-liter V8 making 450 horsepower. By bolting a 2.9-liter supercharger, they're able to get it to 700 hp immediately. But the version in this video has a little over 800 ponies. With this kind of power, the Goliath 6x6 is supposedly able to do 60 mph (97 kph) in about 4 seconds.

We really love the exhaust on this thing. It doesn't sound like a supercharged Camaro or Corvette. There's more meat on the bone, a deeper burble, plus it doesn't rev like crazy (to be expected on such a heavy truck).

There’s a full new rear suspension setup to cope with the modifications, as well as specialist 35-inch tires and a roll-bar upgrade. It's not cheap, though. Only 24 of these are ever going to be built at a price of at least $375,000 each.

If you just want the power, you can buy the supercharger system alone for $30,000 or upgrade your suspension for $20,000. What kind of person can even afford a vehicle like that? Well, according to Hennessey, the first 6x6 buyer was a fellow by the name of Bob Berard, owner of the largest potato farm in the state of Wisconsin. Hood hustle, Bob!
