Hennessey Mammoth 6x6 Ram TRX Truck

Hennessey is no stranger to over-the-top builds, with 15 of their Ford VelociRaptor and Chevrolet Goliath 6x6 trucks leaving their Texas facilities over the last three years. Ram just announced their Hellcat-powered TRX truck, and Hennessey already has a 6x6 in the works for a very limited run of three trucks — with a 1,200 horsepower Mopar Hellephant crate motor. This means the Mammoth will be the most powerful and expensive truck Hennessey has ever offered, and for them, that's a real feat. Along with the Hellephant motor and extra axle, a bespoke interior, full suite of suspension upgrades, and new front and rear bumpers with LED lighting will be included, along with the base Ram TRX, for $500,000. Orders open on September 3, 2021.
