Hennessey’s GOLIATH Supercharged GMC Sierra Gets 700HP

Oh boy, Hennessey have done it again. This time, the Texas tuners have taken a 2020 GMC Sierra, with a 6.2-liter V8, and added a 2.9-liter supercharger. The resulting GOLIATH has a giant 700 horsepower at 6300 rpm, which will make 0-60 in just 4.3 seconds!

The GOLIATH isn’t just faster, it’s also got a custom HPE crankshaft, hardened pushrods, chassis dyno ECU tune, and a 200-mile road tune. Hennessey have also added some of their cool cosmetic features, like a numbered engine and dash plaque, embroidered headrests, and exterior badging.

There will only be 100 of these made, with the price (including the donor truck) coming in at $105,000. Alternatively, you could bring your own 2020 GMC Sierra, and the supercharger kit would only cost you $29,950.

If the standard GOLIATH features aren’t enough for you, they’ve also got an off-road package. If you pony up the additional $18,950, it will get you a six-inch lift, 20-inch HPE Wheels, 35-inch Toyo Tires and custom GOLIATH front bumper with LED lighting. Which honestly, the offroad kit seems obligatory, with the Hennessey lifestyle representing the “go big or go home” mentality, you wouldn’t want the least big and beefy 700 hp Sierra.

Each GOLIATH 700 comes with a 3 year / 36,000-mile warranty for all of the upgrades from Hennessey. If you’re looking to pick one up, they can be ordered directly from Hennessey, or from any GMC dealer.
