The 2024 Ram 1500 Crew Cab RHO 3.0 SST HO 4×4 represents the high-performance pinnacle of the DT-generation Ram 1500 lineup, introduced with the 2024 facelift. Positioned as a direct competitor to performance-oriented full-size trucks like the Ford Raptor and Chevrolet Silverado ZR2, the RHO (Ram High Output) model delivers substantial power and off-road capability. Production began in 2024, building upon the established Ram 1500 platform known for its comfortable ride and robust construction. This variant specifically targets buyers seeking a blend of everyday usability and exhilarating performance, differentiating itself from the more fuel-efficient or work-focused trims within the 1500 range.

Powertrain & Engine Architecture
The heart of the Ram 1500 RHO is the Hurricane 3.0-liter inline-six engine, specifically the “SST HO” (Supercharged Straight-Six High Output) variant. This engine produces 540 horsepower at 5700 rpm and 707 Nm (521.46 lb-ft) of torque at 3500 rpm. It utilizes a twin-scroll turbocharger setup with an intercooler, coupled with direct fuel injection. The engine’s design prioritizes both power density and responsiveness. The Hurricane engine is a significant departure from traditional V8 engines, offering comparable or superior performance with improved efficiency. The engine is paired with the TorqueFlite 8-speed automatic transmission, optimized for both on-road comfort and off-road crawling. The transmission features a wide gear ratio spread, allowing for quick acceleration and efficient highway cruising.
Driving Characteristics
The RHO’s performance is markedly different from other 1500 trims. The 0-60 mph sprint takes just 4.6 seconds, a figure more akin to a sports car than a full-size pickup. The twin-turbocharged inline-six delivers strong, consistent power throughout the rev range, minimizing turbo lag. The 8-speed automatic transmission shifts smoothly and decisively, keeping the engine in its optimal power band. While the RHO is capable off-road, its increased weight and performance-tuned suspension result in a slightly firmer ride compared to standard 1500 models. The gear ratios are tuned for acceleration, meaning highway fuel economy suffers somewhat compared to lower-output versions.
Equipment & Trim Levels
The RHO trim comes standard with a comprehensive suite of features, including a premium interior with leather upholstery, heated and ventilated front seats, a large touchscreen infotainment system with navigation, and a premium sound system. Standard exterior features include unique styling cues, such as a distinctive hood, aggressive front fascia, and flared fenders. Optional extras include a panoramic sunroof, advanced driver-assistance systems (ADAS), and a bed-mounted spare tire carrier. The RHO is essentially a fully-loaded trim, with fewer standalone options available compared to lower trims.
Chassis & Braking
The RHO features a reinforced chassis and upgraded suspension components to handle the increased power and stress. The front suspension utilizes coil springs and a double wishbone setup with a transverse stabilizer bar, while the rear employs a solid axle with coil springs. Braking duties are handled by ventilated discs at all four corners, measuring 378×30 mm at the front and 375×22 mm at the rear. The RHO also includes an anti-lock braking system (ABS) and electronic stability control. The increased ride height (300 mm / 11.81 in) provides ample ground clearance for off-road adventures.
Market Reception & Comparison
The Ram 1500 RHO has been generally well-received by automotive critics, praised for its impressive performance and unique powertrain. However, its fuel economy (13.8 l/100 km combined) is significantly lower than that of other 1500 trims, particularly those equipped with the EcoDiesel engine. Compared to the Ford Raptor, the RHO offers a more refined interior and a more comfortable ride, while the Raptor excels in extreme off-road performance. Against the Chevrolet Silverado ZR2, the RHO provides a more powerful engine and a more luxurious interior.
Legacy
The Hurricane engine represents a significant step forward in truck engine technology, offering a compelling alternative to traditional V8s. While long-term reliability data is still emerging, the Hurricane engine is built with robust components and is expected to be durable. The RHO trim is likely to become a sought-after model on the used car market, appealing to buyers who prioritize performance and exclusivity. Its introduction has pushed competitors to innovate and offer more powerful and capable trucks, ultimately benefiting consumers.
