Texas tuner, Hennessey (HPE), has taken the already capable Chevrolet Silverado ZR2 and turned it into something far more extreme, unveiling the new Goliath 700 ZR2 – a supercharged, off-road-focused pickup pushing out an impressive 700hp (522kW).

For Australian buyers, Hennessey vehicles are available locally through KPM Motorsport, the brand’s exclusive Australian partner and authorised builder. The South Australian outfit currently offers a limited range of Hennessey-enhanced vehicles, spanning models such as the Ford Mustang, Ranger VelociRaptor, Chevrolet Camaro 2SS and ZL1, Dodge Challenger Hellcat and Demon, and Jeep Trackhawk.

At the heart of the Goliath 700 upgrade is a heavily reworked version of the Silverado’s 6.2-litre V8. Thanks to a twin-screw supercharger with air-to-water intercooling and Hennessey’s own engine management calibration, output jumps by 66 per cent, from 420bhp (313kW) to 700bhp (522kW) at 5500rpm. Torque also sees a healthy increase, climbing from 460lb-ft (624Nm) to 611lb-ft (828Nm) at 4200rpm.

The performance gains are just as dramatic as the numbers suggest. Hennessey claims a 0 to 60mph (0 to 97km/h) sprint of just 4.2 seconds, a significant improvement over the stock truck’s 5.6-second run, putting it firmly into high-performance territory for a full-size off-roader. Hennessey has also focused heavily on improving off-road capability and overall drivability. A BDS suspension upgrade paired with integrated Multimatic DSSV shocks enhances stability and control both on-road and when tackling rough terrain.

Visually, the truck separates itself clearly from the standard ZR2. Carbon-fibre plays a major role, highlighted by a functional hood vent that replaces the factory applique to improve airflow and engine cooling. Steel front and rear bumpers, 20-inch off-road wheels, 35-inch tyres, and integrated LED lighting complete the aggressive, purpose-built look.

“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.”

Hennessey positions the Goliath 700 as a serious alternative to factory-backed high-performance trucks like the Ford Raptor R and Ram TRX, offering Chevrolet fans a similarly extreme option with both power and presence.

Production will be limited to just 100 units, each priced from $139,950 USD (approximately $210,000 AUD).
