Now Anyone Can Buy a Hennessey Goliath

Despite the inherent awesomeness of the Hennessey Goliath 6×6, the Texas tuner was never going to make more than 24. And with a $375,000 price tag, it seemed doomed to exclusivity. But Hennessey Performance Engineering announcing a possible power upgrade for the Goliath made us curious. With production so limited, why the boost? Turns out, the tuner wasn’t referring to the 6-wheeled version. Hennessey recently introduced the Goliath 500 and Goliath 700, two high-horsepower trucks based on the Chevrolet Silverado and GMC Sierra. And getting either one is going to be significantly easier than the 6-wheeler.

How the Hennessey Goliath 500 and 700 are both less and more extreme than the Goliath 6×6

Sadly, and inevitably, the Goliath 500/700 don’t have the 6×6’s extra axle. Also, the Goliath 6×6 builds off the Silverado Trail Boss Z71, making it even more off-road-capable. But, the 6×6 needed that specific truck as the donor. The two new Goliaths, on the other hand, can be built from any V8-equipped Silverado or Sierra.

Whether using the 5.3-liter or 6.2-liter V8, both Goliath builds boost performance through supercharging. Specifically, a 2.9-liter supercharger. Mounted on the 5.3-liter Goliath 500, it boosts power from 355 hp to 500 (hence the name). The Goliath 700 makes 700 hp with the same system, compared to the base V8’s 420 hp.

The Goliath 700 actually makes more power than the Goliath 6×6, which only came with 450 hp. And with that power, Hennessey states the truck can go from 0-60 in 4.3 seconds. According to Car and Driver, that’s faster than the Ford F-150 Raptor.

But Hennessey didn’t just stick a blower onto the V8 and call it day. The tuner also installs high-flow intercooling and air induction systems, as well as a crankcase ventilation system, to keep everything at the right temperature. The engine is also recalibrated by HPE and gets chromoly pushrods to keep up with the stress.

The rest of the Goliath 500/700 also gets some upgrades. The outside gets some identifying badging, and the headrests receive some Hennessey embroidering.

Goliath off-road Stage 1 and Stage 2 packages

Know how the Goliath 6×6 used a Silverado Trail Boss Z71 as the donor? The Goliath 500 and 700 can, as well. But even a base Silverado or Sierra can be turned into an off-road warrior with the option packages Hennessey offers for the Goliath.

The Stage 1 package adds new “GOLIATH” front and rear bumpers, with the front featuring new LED lights. The stock wheels and tires are replaced with 20” Hennessey wheels and 35” Toyo off-road tires. And finally, the truck is lifted by 3.5-4.5”, depending on the donor’s trim level.

The Stage 2 package goes even further. The tires now become 37” Toyos, lift shoots to 6”, and the suspension gets a full upgrade. And to help buyers get into their Goliaths, Hennessey also installs electronic fold-out steps.

Pricing and availability

Hennessey has not revealed pricing details for either the Goliath 500 or 700. The off-road packages’ pricing has also not been revealed.

However, Hennessey claims that the Goliath can be ordered from any Chevrolet or GMC dealer. In addition, all Goliath builds and parts come with a 3-year/36,000-mile warranty.

Hennessey Goliath 500 and 700 vs. the competition

The closest competition to the Goliath trucks actually comes from Hennessey itself. The tuner also offers the Raptor 600 Twin Turbo and the Ranger VelociRaptor, which are similar to the Goliaths. These trucks are meant for high-speed desert excursions, as opposed to something like the AEV Recruit, which is more for rock-crawling and overlanding. The Ram-based Recruit also gets no power upgrades.

Without knowing the Goliath’s pricing, value is difficult to compare. However, the base $45,000 VelociRaptor is smaller than the Goliath and significantly less powerful. With 360 hp, even with a lighter weight, it takes 4.9 seconds to hit 60.

The 600-hp Raptor Twin Turbo, on the other hand, needs only 4.2 seconds. Getting one requires adding $22,500—according to Digital Trends—on top of the base Raptor’s $53,000 MSRP. Meanwhile, a base Silverado WT starts $28,300 before options and the Custom Trail Boss with Z71 package at $39,500.
