Hennessey Unleashes ‘GOLIATH 700’ Supercharged Silverado ZR2

SEALY, TEXAS — Hennessey has revealed the GOLIATH 700 ZR2, a 700-horsepower supercharged upgrade package for the 2026 Chevrolet Silverado ZR2. A twin-screw supercharger with air-to-water intercooling and Hennessey engine management calibration lifts the 6.2L V8 from 420 to 700 bhp at 5,500 rpm and torque from 460 to 611 lb-ft at 4,200 rpm, cutting the 0-60 mph sprint from 5.6 seconds to 4.2. Chassis upgrades include a BDS suspension system with upper control arms and Multimatic DSSV shocks, plus 20-inch Hennessey off-road wheels wrapped in 35-inch tires and a stainless cat-back exhaust. The exterior gets exposed carbon fiber bodywork including a functional vented hood applique, steel front and rear bumpers, LED lighting, and Goliath badging. Hennessey says the truck pairs extreme power and capability with everyday usability and comfort, targeting buyers who want presence on the highway and confidence off-road. Production is limited to 100 serialized units at $139,950 MSRP, sold exclusively through Hennessey-authorized Chevrolet dealers and backed by a 3-year/36,000-mile limited warranty.
