HEMI V8 Power Continues its Legacy in Ram Heavy Duty Lineup
As the automotive industry shifts gears, a powerful rumble echoes for fans of the legendary HEMI V8. The iconic 6.4-liter (392 cubic-inch) engine, nicknamed the “Big Gas Engine,” will continue to flex its muscle under the hood of the Ram 2500 and 3500 Heavy Duty trucks. The 6.4-liter HEMI V8 is a muscle-packed engine delivering an impressive 410 horsepower and 429 lb-ft of torque, making it the ideal companion for hauling heavy loads and tackling demanding jobs. Furthermore, the HEMI V8 incorporates smart technology like Variable Valve Timing (VVT) to optimize performance, while Fuel Saver Technology with cylinder deactivation helps improve efficiency during highway cruising.
The HEMI V8 prioritizes low-end torque for heavy-duty applications. Compared to its predecessor, the Apache, it boasts an intake manifold with a top-mounted throttle body designed for maximum power delivery between 3,600 and 5,000 rpm. Additionally, a lowered compression ratio (10.0:1) and redesigned pistons with oil jets and floating pins contribute to improved efficiency and heat management under heavy loads. While the HEMI V8 utilizes the same large valves (2.14-inch intake and 1.65-inch exhaust) as the Apache engine, its cylinder heads are crafted from high-grade T356 aluminum to withstand the extreme temperatures and stress encountered during heavy towing.
The 6.4-liter HEMI V8 in Ram 2500/3500 trucks prioritizes durability with a stainless-steel exhaust manifold and high-quality gaskets and fasteners. This ensures exceptional performance even under high temperatures encountered during heavy-duty tasks. Meeting Modern Standards: As Ram undergoes its 2025 mid-cycle refresh, the HEMI V8 receives updates to comply with the latest emission regulations. While these regulations differ for heavy-duty trucks compared to lighter vehicles, Ram has implemented necessary changes to ensure the engine remains compliant with evolving environmental standards.
