John Hennessey is a man known for his penchant towards automotive excess. His Texas-based tuning company Hennessey Performance Engineering is known for cranking out some seriously ludicrous machines, ranging from 6×6-converted pickup trucks to a 300+ MPH capable hypercar. Now though, the company has just pulled the wraps off of one what can really only be defined as the ultimate family hauler. This is the Hennessey Mammoth 1000 SUV, or what you might call a Ram 1500 TRX turned three-row SUV. And yes, it does make over 1,000 horsepower.
When building a crazy vehicle, it makes sense to start with something that is already a bit out there. Considering the Ram 1500 TRX is a 702 horsepower off-road weapon, we’re apt to believe Hennessey Performance Engineering nailed that step. That said, this is just the latest chapter in their Hennessey Mammoth lineup. Power output on this particular machine is rated at 1,012 horsepower and 969 lb-ft of torque, which will allow for a 0-60 mph time of just 3.2 seconds. Underpinning that power is Hennessey Performance Engineering’s own Mammoth Off-Road package, which includes a 2.5-inch lift and leveling kit, custom bumpers front and rear with integrated LED lighting, 20-inch Hennessey 10-spoke wheels, and 35-inch off-road tires.
The Hennessey Mammoth 1000 SUV is slated to feature seven seats, thanks to the second row captain’s chairs and folding third row bench seat. In order to accomplish this, the tuning shop has had to dramatically rework the chassis of the TRX, which is likely why they only have plans to build 20 examples. Would it have been easier to start with a Durango Hellcat? Almost certainly. That said, this thing looks seriously cool.
The Hennessey Mammoth 1000 SUV is currently slated to arrive with an MSRP of $375,000. That is certainly a lot of cash, but we’re sure Hennessey Performance Engineering already has more than 20 people who are interested in getting their hands on one of these things. For that reason, it makes one wonder why Ram is so hesitant to drop an SUV of their own. Regardless, we’re sure this thing is going to be quite the do-it-all 4×4. Now if only John decided this was the place he wanted to stick that Hellephant V8 that he has lying around.
