When a standard TRX won't do, Hennessey steps in with the insane Mammoth.

The 2022 Mammoth TRX by Hennessey Performance is a truly wild creation. In order for this truck to happen, Hennessey had to look at the already powerful RAM 1500 TRX and say: "This needs to be better and more powerful." Then again, that is exactly what Hennessey has been doing for years. After upgrading the TRX with a slew of modifications and upgrades, the Mammoth TRX was born. Packing up to 1,012 horsepower and 969 lb-ft of torque, the Mammoth TRX can sprint from 0 to 60 mph in just 3.2 seconds. That kind of acceleration allows the Mammoth TRX to not only line up against many supercars but also dominate them. And while orders for the 2021 Mammoth TRX have been closed, Hennessey Performance has announced that reservations for the 2022 model are now open.
