Hennessey Unveils Ram TRX SUV

Hennessey Performance, the Texas-based high-performance vehicle builder, has unveiled a new model for 2021: the Hennessey Mammoth 1000 SUV.

Boasting 1,012 hp from its supercharged 6.2-liter V8 and capable of 0-60 mph in 3.2 seconds, the new SUV can seat seven adults in comfort and will be a limited edition with just 20 models being produced.

Based on the new Ram TRX, the enhancement by Hennessey Performance sees bespoke bodywork extend the roofline to meet a new C-pillar that sits above the rear taillights. The conversion incorporates a rear-side window and adds a rear screen while retaining luggage space behind the third row of seats.

“I have a big family with five kids and have always enjoyed owing big, powerful SUV’s. In 2012 we converted the first-generation Ford Raptor into our VelociRaptor SUV – I still own one today and love it,” said John Hennessey, company founder and CEO. “Now, we are excited to offer something very similar, but with a lot more horsepower using the new Ram TRX truck as our base vehicle. Creating this king of SUVs offers our customers the ultimate combination of space, power and exclusivity.”

The complete, turnkey, vehicle is built upon the 2021 Ram 1500 TRX. Alongside the all-new bodywork, the Hennessey engineers upgrade the supercharger system alongside new HPE engine calibration. This sees power output jump 310 hp to 1,012 hp, while torque is boosted by 319 lb-ft to 969 lb-ft of torque.

The SUV variant also benefits from Hennessey’s Mammoth Off Road package, which includes a 2.5-inch lift, custom front bumper with LED lights, 20-inch Hennessey 10-spoke wheels, 35-inch off-road tires and a front suspension leveling kit.
