Blessed with a third axle and a Hellephant engine tuned up to 1200 HP, this RAM TRX is now equipped to live its best life as a Hennessey MAMMOTH 6x6. The Hellephant-powered 6x6 production run, limited to three examples, has concluded but Hennessey is proud to continue offering 6x6 conversions for the still-ridiculous MAMMOTH 1000-upgraded RAM TRX. In this video, some of the Hennessey team loaded into this monolithic machine for a final shakedown on the Pennzoil Proving Ground. Hennessey MAMMOTH 6X6 Vehicle Page: Stay tuned!
