Hennessey's monster 1,032 hp Ram pickup can hit 200 mph
Hennessey has revealed the Maximus, a supercharged Ram 1500 Rumble Bee SRT tuned to 1,032 hp and 1,283 Nm, with an estimated 200 mph top speed that the truck can only reach once its own rear wing has been unbolted
Hennessey Performance has taken its scalpel to the Ram 1500 Rumble Bee SRT, the factory truck's 777 hp supercharged Hellcat V8 already a serious starting point, and built the Maximus around it. Hennessey names the Ram SRT-10, its own Venom 650R Viper and three decades of its own tuning work as the inspiration, the same shop that recently sent a 2,031 hp hypercar down the road with a manual gearbox, and says the goal was simple: “pushing a pickup into territory few thought possible.”
What actually changes under the bodywork
The Maximus keeps the Rumble Bee's supercharged 6.2-litre Hellcat V8 but adds a higher-flow supercharger and revised engine calibration, lifting output to 1,032 hp (770 kW) and 947 lb-ft (1,283 Nm) of torque, a gain of 255 hp and 267 lb-ft over the standard truck. Hennessey has not detailed every mechanical change beyond the supercharger and tuning work, so treat the full parts list as unconfirmed until the truck reaches production.
Three seconds to 60, and a catch on the top end
Hennessey quotes a 0 to 60 mph time of 3.0 seconds and a quarter mile in 10.9 seconds, figures that would embarrass plenty of sports cars regardless of the extra weight and height of a pickup bed. The claimed 200 mph top speed is more conditional: reaching it reportedly requires removing the truck's own rear wing first, which says something about how much drag the rest of the body still generates even after Hennessey's changes.
The body kit and cabin
Visually, the Maximus gets a VenomAero body kit with a front splitter, side skirts and the rear wing in question, plus carbon fibre trim, a lowered air suspension, 22-inch wheels, a hard tonneau cover and Maximus-specific graphics and badging. Inside, Hennessey fits what it calls an elevated cabin, with leather and Alcantara upholstery and branded floor mats, backed by a 3-year, 36,000-mile warranty.
Price and timing remain open questions
Hennessey has not published a price or confirmed production numbers, describing the Maximus only as “coming soon” for 2027. Industry estimates point to a low six-figure price, likely upward of $150,000, based on where Hennessey positioned its previous Ram TRX Mammoth, with production reportedly expected to start before spring 2027 and customer deliveries following that summer. Treat both the price and the delivery window as informed guesses rather than confirmed figures until Hennessey says otherwise.
AutoNext Take
A 1,032 hp pickup truck that can out-accelerate most sports cars to 60 mph is exactly the kind of unhinged excess Hennessey has built its name on, and the underlying Rumble Bee SRT was already a genuinely serious machine before anyone added a supercharger upgrade. The 200 mph claim is the part worth watching rather than taking at face value: needing to physically remove the rear wing to get there is an honest admission that the rest of the body is still working against it at speed, and Hennessey has not yet backed the number with an independently verified run.
None of that undercuts what this actually is. Whether it lands at $150,000 or considerably more, a three-second pickup truck with a warranty is a strange and slightly wonderful thing to be able to buy from a factory-backed programme rather than a backyard build, from the same company that just proved with its own naturally aspirated Blackbird that it knows when to dial the madness back, too.
