Hennessey Goliath 700: GMC Sierra AT4 Gets a New Coastal Dune Look
Соцсети Hennessy Performance
Hennessey unveils a beige Coastal Dune version of its 700-hp Goliath package for the GMC Sierra AT4, a supercharged V8 rival to the Raptor R and TRX.
Hennessey has shown off a new example of the Goliath 700, built on the GMC Sierra AT4. The project actually debuted back on May 27, 2026, so the real news here isn’t the technical package but the truck’s new beige Coastal Dune paint.
Instead of the stock 420 bhp, the 6.2-liter V8 now produces 700 bhp — about 710 hp. Torque climbs from 460 lb-ft to 611 lb-ft. The gains come from a Twin-Screw supercharger, a liquid-to-air intercooler, a new ECU tune and a stainless-steel exhaust system. The pickup sprints to 60 mph in 4.2 seconds.
For off-road duty, the truck gets a BDS suspension with upper control arms, Multimatic DSSV dampers, 20-inch wheels and 35-inch tires. Steel bumpers are paired with underbody protection, a 40-inch LED light bar and auxiliary lights. Carbon fiber covers the hood and tailgate accents.
Inside, there are embroidered headrests, all-weather floor mats and a numbered plaque. Hennessey bench- and road-tests every vehicle and backs it with a limited warranty of three years or 36,000 miles.
The company positions the Goliath 700 as an alternative to the Ford F-150 Raptor R and Ram 1500 TRX. Still, it remains a modified Sierra rather than a separate factory GMC trim. Hennessey also doesn’t publish a fixed price for the build, inviting buyers to request a custom quote instead.
