Seven-metre-long truck is Hennessey’s biggest pick-up yet and driven by an uprated 6.2-litre supercharged Hellcat V8
American performance engineering firm Hennessey has revealed its largest vehicle yet: a six-wheeled truck with more than 1000bhp.
The Hennessey Mammoth 1000 6×6, based on the Ram TRX, is 7190mm long, 2133mm tall and 2235mm wide.
Under the bonnet sits a 6.2-litre supercharged Hellcat V8 engine from the donor Ram, but it has been uprated from the standard engine to produce 1012bhp – an increase of more than 300bhp.
Autocar has contacted Hennessey for detailed performance figures.
A 319lb ft increase over the Ram’s standard torque figure means the Mammoth produces 969lb ft.
On top of its huge power increase, the Mammoth gains an off-road kit with Bilstein suspension and locking rear axles.
Six 20in wheels are fitted with 37in off-road tyres. The addition of a third axle extends the model’s length by 1219mm. It’s also equipped with more rugged-looking front and rear bumpers and LED lights.
John Hennessey, the firm’s founder and CEO, said: “Everything we do at Hennessey Performance is turned up to 11, but the Mammoth 1000 6×6 is definitely turned up to 12.
“Everything on the Mammoth 6×6 is bigger, badder and more imposing – plus, it’s still super-fast, while being a total powerhouse off road. It’s the undisputed king of the road.”
Prices for the Hennessey Mammoth 1000 6×6 start from $449,950 (£344,297), including the cost of the base Ram TRX. Just 12 cars will be built each year.
The Mammoth is Hennessey’s third and most powerful six-wheel pick-up model. It follows the Ford Ranger-based VelociRaptor 6×6, which produced 600bhp, and the Goliath 6×6 Silverado, which is based on the Chevrolet Silverado and produced 800bhp.
