Hennessey’s 2020 GMC Sierra And Chevy Silverado Goliath Will Obliterate A Civic Type R In 0-60 MPH Sprint

The 2020 GMC Sierra and Chevrolet Silverado are the latest pickup trucks to be transformed by Hennessey Performance with the Texas tuner announcing it has started production of its Goliath upgrade package for the duo, first unveiled in February.

The Goliath 700 Supercharged upgrade is available for models with the 6.2-liter V8 engine and adds a 2.9-liter supercharger running six pounds of boost. Complementing the supercharger is a high-flow intercooling system, high-flow air induction system, custom camshaft, Chromoly hardened pushrods, a crankcase ventilation system, and engine management calibration that sees the GMC Sierra and Chevrolet Silverado lifted to 700 hp at 6,300 rpm, resulting in a 0-60 mph (96 km/h) time of just 4.3 seconds.

That’s pretty fast nearly matching the BMW M2 Competition’s 4.2 second run, while leaving hot hatches like Honda’s popular Civic Type R in their dust (5.4 sec).

It’s not just straight-line performance that Hennessey has focused on with its Goliath package as a plethora of parts have been designed to improve the off-roading credentials of the pickups. This includes a new front bumper, new LED lights at the front, 20-inch Hennessey 10-spoke wheels finished in black, 35-inch Toyo off-road tires, and an available 6-inch lift kit for certain trim levels. Hennessey and Goliath graphics are also available.

Hennessey has also worked in the cabins of the Sierra and Silverado, designing embroidered headrests and a serial-numbered dash plaque. There is also a special engine plaque.

Customers who want the engine modifications, as well as the new interior trimmings, will need to part ways with $29,950 while those who opt for the available off-road package will need to cough up an additional $18,950. Other optional upgrades include a complete diamond-stitched interior ($5,950), ram air hood ($5,950), stainless steel catback exhaust ($2,750), retractable electronic bed cover ($4,450), and upgraded electronic fold-out steps for $3,450. Hennessey will produce just 100 Goliath Sierra and Silverado models per year.
