Hennessey unveils 1,000hp Mammoth

Texas tuning house turns up the wick on Ram's 702hp 1500 TRX

Hennessey has revealed its take on the Ram 1500 TRX, which has been christened the Mammoth thanks to its preposterous 1,000hp output. The supercharged V8 pick-up, which in standard tune already produces 702hp, has been given a host of upgraded hardware both under the bonnet and around the chassis as well. The result is the most potent pick-up to come out of Hennessey’s Texas workshop, with a claimed 0-60mph time of 3.2 seconds.

The tuner says its pick-up is also capable of an 11.4-second quarter mile sprint, where it crosses the line at 120mph. Not bad for something that weighs 2.8-tonnes and is shaped like a breeze block. To achieve its monumental – or mammoth – four-figure output and 969lb ft of torque, the team fitted a 2.65-litre supercharger to the 6.2 V8, with pulley upgrades, stainless-steel headers and a freer-flowing exhaust. Mods have also been made to the fuel injection and intake system, and it’s all optimised with an in-house ECU calibration.

Elsewhere, Hennessey has applied its tough off-road stage 1 pack to the TRX. It provides a 2.5-inch lift (or 63.5mm) kit for the suspension, 10-spoke alloy wheels with off-road tyres, as well a new front bumper sporting LED lights. Out back, there’s a retractable electronic bed cover, and passengers can access the higher pick-up via electronic fold-out steps. Naturally, there’s a bull bar on the front end and intakes on the bonnet. The finished product looks ideal for an enraged visit to the US Capitol.

Those wanting one will have to move quickly because Hennessey is set to produce only 200. Obviously, it’s for Americans – being the most American thing ever – but there's nothing to stop you privately importing one, aside from the usual red tape. And as Monday's MS-RT Ranger showed, the popularity of pick-ups in the UK shows no sign of dropping off. The temptation of owning one with SF90 Stradale-rivalling power might be too much for some…
