Hennessey Unveils New Goliath 700 Silverado

Building a reputation for performance expertise over decades, Hennessey is known for record-breaking hypercars as well as its customizations of American icons. The latest based on the Chevrolet Silverado is the new Hennessey Goliath 700, which adds massive amounts of power to the truck’s 6.2-liter V8 engine thanks to supercharging and other upgrades. The highlight of the custom truck is its twin-screw supercharger, which uses air-to-water intercooling and Hennessey engine management calibration to increase the power of the 6.2-liter V8 by 66 percent, going from 420 horsepower to a massive 700. The torque goes from 460 to 611 lb/ft. However, other upgrades are present in the new Hennessey Goliath 700, including a BDS suspension upgrade and Multimatic DSSV shocks, and Hennessey design touches in carbon fiber, as well as badging, add a distinctive look that sets the truck apart. With a 4.2-second 0-60 time, the Goliath 700 accelerates faster than the stock Chevrolet Silverado ZR2 by 1.4 seconds, and customers can purchase the upgraded truck via Hennessey-authorized Chevrolet dealers at an MSRP of $139,950. With a limited production run of just 100 examples, the new Hennessey Goliath 700 Silverado ZR2 also enjoys a 3-year/36,000-mile limited warranty.
