Hennessey Performance announced that the 2021 Ram TRX will be the basis for the Sealy, Texas aftermarket specialist’s most powerful, exclusive, and expensive pickup truck ever—the “Mammoth” 6×6.
With a 702-horsepower supercharged 6.2-liter HEMI V8, the stock TRX is already the most powerful production half-ton pickup on the market. Naturally, Hennessey is replacing that stock engine with Mopar’s even more massive 7.0-liter Hellphant V8 and tuning the engine to produce over 1,200 hp.
The Mammoth 6×6 will also get a fully-upgraded off-road suspension, front and rear bumpers with LED lights, a bespoke branded interior, and what appears to be an intimidating elephant decal on the passenger door. We’d imagine that the TRX’s eight-speed automatic transmission will be bolstered as well. Only three examples will be produced for an eye-watering $500,000 each.
So far, the these details and the image above are all that have been released, but more info will likely arrive when pre-orders open up on September 4 at 12:00 p.m. CT.
The Mammoth 6×6 follows Hennessey’s Ford F-150 Raptor-based “VelociRaptor” 6X6 and Chevrolet Silverado Trail Boss Z71-based “Goliath” 6X6. While neither pack anywhere close to 1,200-horses, Hennessey’s “Resurrection” Camaro and Corvette ZR1 build are just two of the custom muscle cars offered with that outrageous output.
