Hennessey has revealed the new GOLIATH 700 ZR2, a 700-horsepower supercharged upgrade to the 2026 Chevrolet Silverado ZR2 with 611 pound-feet of torque and off-road capability enhancements. The Texas-based creator of high-performance cars, trucks, and SUVs has reengineered and supercharged the flagship 6.2-liter V8-powered Silverado ZR2, resulting in 0-60 mph in just 4.2 seconds, compared to the 5.6-seconds of the stock truck.
Performance Upgrades of the GOLIATH 700 ZR2
The Hennessey GOLIATH 700 ZR2 features a twin-screw supercharger with air-to-water intercooling and Hennessey engine management calibration. Upgrades to the 6.2-liter V-8 powertrain boost output by 66%—700 bhp at 5,500 rpm versus 420 bhp stock—while torque climbs to 611 pound-feet at 4,200 rpm (460 pound-feet stock).
Capability is also enhanced with extensive chassis and suspension enhancements, including a BDS suspension upgrade and integrated Multimatic DSSV shocks, improving control, stability and driver confidence both on pavement and off the beaten path. The truck is visually differentiated with unique Hennessey carbon-fiber bodywork enhancements and badging.
“The Hennessey GOLIATH 700 ZR2 is designed for customers who want extreme power and capability without compromising on usability and comfort,” said Alex Roys, president of Hennessey. “We deliver performance dominance and heaps of presence by combining powertrain and chassis upgrades with comprehensive exterior and interior styling enhancements. We’ve created a truck with purpose that feels just as confident on the highway as it does tackling challenging terrain.”
Style & Functionality Upgrades
Visually, the GOLIATH 700 ZR2 is distinguished by a series of carbon-fiber enhancements, most notably, the Hennessey team replaces the factory ZR2 hood applique with a functional carbon-fiber hood vent that enhances airflow and improves engine-bay cooling. Hennessey Goliath steel front and rear bumpers, 20-inch Hennessey off-road wheels, 35-inch off-road tires and integrated LED lighting further reinforce the truck’s aggressive stance and purpose-built capability.
Hennessey claims the newest creation delivers the style, presence and muscle that finally gives Chevrolet buyers a factory-backed alternative to the Ford Raptor R and Ram TRX. Priced at $139,950 MSRP and available now through Hennessey-authorized Chevrolet dealers, each of the 100-unit limited run GOLIATH 700 ZR2 trucks is backed by a 3-year/36,000-mile limited warranty.
