Ram 1500 RHO 0-60 Acceleration, Quarter-Mile & Dragy Telemetry
Official factory ratings claim the 2025 Ram 1500 RHO accelerates from 0 to 60 mph in 3.5 seconds using Launch Control with 1-foot rollout. Independent real-world GPS Dragy tests on unprepared asphalt record 0-60 mph times between 4.1 and 4.4 seconds, with an electronically limited top speed of 118 mph.
Step-by-Step Launch Control Activation Procedure
The 2025 Ram 1500 RHO is equipped with a dedicated Launch Control driver assistance module integrated into the Selec-Speed powertrain computer. To replicate the factory 3.5-second 0-60 claim, drivers must execute a precise mechanical sequence.
1. System Engagement & Pre-Check
First, ensure the vehicle is operating on a level surface with engine oil temperature above 160°F (71°C) and transmission fluid temperature below 210°F (99°C). Select 'Sport' or 'Baja' dynamic driving mode via the steering wheel drive-mode toggle. Depress the physical 'Launch' button located adjacent to the 4WD transfer case selector on the center stack.
2. Torque-Converter Brake Stall Calibration
With your left foot pressing firmly on the brake pedal (exerting at least 450 PSI hydraulic brake pressure), smoothly depress the accelerator pedal to 100% wide-open throttle with your right foot. The ECU will hold engine speed between 2,200 and 2,500 RPM while building up to 18 PSI of pre-spool boost pressure. Within 3 seconds, abruptly side-step release the brake pedal.
Real-World Dragy GPS Benchmarks vs Manufacturer Claims
Discrepancies between official OEM marketing brochures and enthusiast drag-strip reality frequently cause confusion. Stellantis quotes 3.5 seconds for the Ram RHO, measured using NHRA drag racing standards with a 1-foot rollout deducted on a prepped VHT surface.
True Standing Street Start Reality (0-Foot Rollout)
When tested on real-world asphalt roads using 10Hz Dragy satellite telemetry with zero rollout deducted, the 2025 Ram RHO records 0-60 mph times between 4.15 and 4.38 seconds. The 6,396-pound curb weight and massive 35-inch all-terrain tire tread blocks require approximately 0.30 seconds simply to overcome static inertia and begin moving across the optical timing line.
Quarter-Mile Telemetry: 12.8s @ 107 MPH Trap
Across independent instrumented testing by Car and Driver and MotorTrend, the RHO reliably hits the quarter-mile timing beam in 12.8 seconds with a trap speed of 107.4 mph. Through the first 60 feet, the truck posts a rapid 1.88-second split, demonstrating exceptional mechanical grip from the BorgWarner 48-13 active all-wheel-drive transfer case.
Top Speed Limiter: Why Stellantis Caps the RHO at 118 MPH
Despite having 540 horsepower capable of pushing a streamlined vehicle well beyond 150 mph, the 2025 Ram 1500 RHO is electronically governed to a maximum top speed of exactly 118 mph (190 km/h).
This speed restriction is mandated by safety compliance related to tire construction. The factory-fitted Goodyear Wrangler Territory All-Terrain tires (325/65R18) carry a Department of Transportation 'T' speed rating. A T-rating certifies safe continuous operation up to exactly 118 mph under maximum load. Exceeding this velocity with heavy, deep-void off-road tires generates extreme centrifugal heat expansion that risks tread delamination and catastrophic carcass blowout. The electronic limiter protects vehicle occupants and maintains full warranty integrity.
Frequently Asked Questions: Acceleration & Speed
Detailed technical answers covering torque-converter stall RPM, tire speed ratings, and quarter-mile telemetry.
01 What is the true real-world 0-60 mph time of the Ram RHO?
While Ram advertises 3.5 seconds using 1-foot rollout on a prepped drag surface, independent 10Hz Dragy GPS instrument tests on unprepared street asphalt record real-world 0-60 mph times between 4.15 and 4.38 seconds on 93 premium octane.
02 How do you engage Launch Control on the 2025 Ram RHO?
To activate Launch Control: ensure engine and transmission fluids are up to operating temperature, select Sport or Baja mode, press the console Launch button, hold the brake pedal firmly (at least 450 PSI), press the accelerator to 100% to stall the torque converter to 2,400 RPM and spool 18 PSI boost, then quickly release the brake pedal.
03 Why is the Ram 1500 RHO top speed limited to 118 mph?
The 118 mph top speed governor is dictated by the Department of Transportation 'T' speed rating of the factory-equipped 35-inch Goodyear Wrangler Territory All-Terrain tires ($325/65R18$). Exceeding 118 mph with heavy off-road tires generates excessive heat and centrifugal stress that risks tire delamination.
04 What is the Ram RHO quarter-mile time and trap speed?
In standardized instrumented testing, the 2025 Ram 1500 RHO covers the standing quarter-mile in 12.8 seconds at a trap speed of 107.4 mph. Its 60-foot launch split time averages 1.88 seconds.
