A close look at the absolutely insane
The Hennessey Performance MAMMOTH 1000 is what you would consider a super truck. Starting with a 2021 RAM TRX, Hennessey Performance then upgrades the engine and brings the power all the way up to 1,000 horsepower from 702 hp. Now, the MAMMOTH 1000 is more than just a power upgrade and also features modifications to its exterior and interior. There are a lot of options to pick from and thankfully Hennessey Performance has uploaded a new video that gives us a good walkaround of the brutal American super truck with the Stage 1 Off-Road package. Click play on the video up above to learn more about the MAMMOTH 1000 and what Hennessey is capable of.
