The RAM 1500 RHO is already fast and fierce out of the box. Hennessey said, “Hold my beer.” The result is the Hennessey Mammoth 700, lifted, lit, and revved to over 700 horsepower—ready to make Baja your backyard.
This is where Texas comes in. Hennessey Performance install package on RHO Hennessey Mammoth 700, which with increased charging pressure, stainless sports exhaust and reprogrammed ECU raises the power to over 700 hp (over ~522 kW). Each instance dyno-checked and taken for a test drive of up to 500 miles (~800 km), then they hand it to you with 3-year/36,000-mile warranty and serial number in the engine compartment. This is tuning with papers, not just Instagram with LED strips.
From terrain to terrain: elevated, armored, illuminated
Hennessey doesn't just rev the engine. The package brings 3-inch (7.6 cm) total lift with front and rear leveling kits, Hennessey front and rear bumper with sensors included and lighting – front 32-inch LED light bar with additional round and corner LEDs. Below is custom underbody protector, and on the side electric escalators, which save your knees from everyday getting in. Wheels? 20-inch Hennessey wheels with 37-inch SUVs; to slow down the pace are available 6-piston performance brakes with steel braided pipes and high-temperature tiles.
Accelerations that are not (yet) mentioned in the prospectus
Hennessey is not currently releasing an official 0–60 mph or terminal velocities for Mammoth 700The workshop is about "over 700 horsepower", but there are no stopwatch numbers - and rightly so, until the measuring equipment arrives. Working hypothesis (based on +160 hp vs. series): expect accelerations deep in the range 4 seconds up to 60 mph. However, this is theory, not a fact; real numbers will depend on the surface, tires (35 vs. 37 inches), weather and – ultimately – the driver’s right foot. For reference: stock RHO 4.4–4.6 seconds.
Competitors and Context: Raptor, TRX, and American Rodeo
RAM emphasizes that RHO has more standard horsepower than a Ford RaptorHennessey and Mammoth 700 raises the bar even higher and makes the RHO a “mini-TRX” in terms of power, but with better fuel economy and lower weight than its predecessor TRX (702 hp)For V8 nostalgics, maybe the “big-bad” RAM will come back someday; until then, it’s Mammoth 700 quite possibly the closest thing to a TRX you can buy today.
Price and orders
Serial RHO in the USA it starts at 69.995 $; Hennessey Mammoth 700 it is available for order. The tuner rarely publishes official price lists; specialized media mention around 70,000 $ for myself Mammoth 700 package (without vehicle), which simply means that the final price of the set generally exceeds six numbersIn Europe, you also have to consider taxes, homologations and logistics.
Hennessey Mammoth 700 is exactly what the name promises: a mammoth among pickups, built from a workshop in Sealy, Texas, and from RAM 1500 RHO make a truck that you can drive next to also Raptor starts scratching his head. We like that the tuner didn't slip into a caricature: the lift is 3 inches, not a ladder to the clouds; the lights are functional, not just “disco”; guarantee and dyno certificate It is the seriousness that separates show car from a machine that lasts. Numbers? The serial RHO is already breaking milestones (4.4–4.6 seconds up to 60 mph), so Mammoth's "over 700 hp"package - carefully put - Fast on paper and even faster in the desert. Prices? Six figures, as befits an ego tripBut honestly: if you're looking for a pickup that takes the kids to school in the morning and easily devours the dunes in the afternoon, this is one of the most engaging, entertaining and – in typical Hennessey style – completely exaggerated ways to do this.
