The all-new 2021 Ram 1500 TRX Hennessey Mammoth will deliver insane performance. If you find Ram TRX with its 702HP engine “too weak,” then this is the answer. The 6.2-liter Hemi will be replaced for a larger 7.0-liter powertrain that will produce 1,200 horsepower. It is a 6×6 model, but not the first one. Whatsoever, we already saw VelociRaptor 6×6 and Goliath 6×6 variants.
However, Hennessey states that the Mammoth 6×6 is the most powerful vehicle the brand has ever made in its 29-year history. Beside six wheels and astonishing performance, Hennessey will work on improving the exterior design. Thanks to that, expect to see visual improvements and more unique features. However, the price is far from affordable, and the manufacturer will build only three copies.

Changes and Upgrades
In terms of upgrades, the new 2021 Ram 1500 Hennessey Mammoth will get a lot of it. Of course, an extra set of wheels is the highlight. However, the truck will also get a bed conversion and a beefier suspension. Hennessey will deliver redesigned bumpers and improved LED headlights.
There is an elephant decal on the door that represents the “Hellephant” engine under the hood. On the inside, the Mammoth variant comes with a bespoke interior, but Hennessey still didn’t provide all of the details. Knowing the price of the arriving truck, the cabin should be full of luxury and modern high-tech features.

2021 Hennessey Mammoth Gets a 1200HP Powertrain
This is undoubtedly the highlight of the upcoming 2021 Ram 1500 Hennessey Mammoth 6×6 truck. If the TRX version with 702 hp eats Ford F-150 Raptor for breakfast, imagine what this model can do. Under the hood, the Mammoth variant won’t use a 6.2-liter V8 as the TRX model. Instead, a larger 7.0-liter Hellephant engine is available. This displacement is capable of producing 1200 horsepower. That is a serious amount of horses, and even Hennessey said it is the most powerful model ever built by the company.
The level of torque is not available at the moment. However, we expect a serious amount of torque. New Ram 1500 TRX will offer 702 hp and 650 lb-ft of torque. This model will sprint from 0 to 60 mph in just 4.5 seconds. The top speed is rated at 118 mph. We are scared to see performance figures for the Hennessey Mammoth truck. However, the manufacturer will release more details in the coming weeks.

2021 Ram 1500 Hennessey Mammoth Price and Release Date
The orders for the 2021 Ram 1500 Hennessey Mammoth will open this Friday. According to Hennessey, it is the most expensive and the most exclusive truck ever made. This truck is priced at mind-whooping $500,000. Yes, you read that well. Moreover, Hennessey will sell its Mammoth 6×6 truck in only three examples. Regular Ram 1500 TRX starts at $71,500.
However, the Mammoth variant provides 1200 horsepower, and it comes with a 6×6 driving configuration. We can’t wait to see this beast on the roads as everything about this truck is just crazy. We’ve seen VelociRaptor 6×6 and Goliath 6×6 trucks, but Mammoth 6×6 is something completely new and different, in our opinion.
