Powertrain & Engine Architecture
At the heart of this RAM 2500 is the 6.4-liter (391.59 cubic inches) HEMI V8 engine, designated as the ESA code. This engine is a naturally aspirated, overhead valve (OHV) design, known for its robust construction and relatively simple maintenance requirements. It utilizes a multi-port fuel injection system, delivering fuel directly into the intake ports. The 6.4L HEMI benefits from variable valve timing (VVT) technology, enhancing both power and fuel efficiency. The engine produces 410 horsepower at 5600 rpm and 429 lb-ft of torque at 4000 rpm. This power is channeled through a six-speed automatic transmission, specifically designed to handle the high torque output of the HEMI engine. The transmission features electronically controlled shifts and tow/haul mode for optimized performance when towing heavy loads.
Driving Characteristics
The 6.4 Hemi V8 paired with the six-speed automatic delivers a noticeably different driving experience compared to the lower-output 5.7L Hemi or the diesel options. Acceleration is brisk, especially considering the truck’s substantial weight. The automatic transmission provides smooth shifts, although it isn’t as quick or sporty as some newer transmissions. The gear ratios are tuned for towing and hauling, prioritizing low-end torque over outright speed. While the 5.7L Hemi requires more frequent downshifting when loaded, the 6.4L offers more readily available power, making highway passing and uphill climbs less strenuous. Compared to the Cummins diesel, the 6.4L is quieter and smoother, but lacks the diesel’s immense low-end torque and fuel efficiency.
Equipment & Trim Levels
The 2500 6.4 Hemi typically came standard with a well-equipped interior, including cloth upholstery, air conditioning, power windows and locks, and a basic infotainment system. Higher trim levels, such as the Laramie and Limited, added features like leather upholstery, heated and ventilated seats, a premium sound system, and advanced safety technologies. Optional extras included a navigation system, rear-seat entertainment, and various appearance packages. Crew Cab models, like the one discussed here, offered spacious seating for up to six passengers, making them a popular choice for families and work crews.
Chassis & Braking
The RAM 2500/3500 utilizes a robust chassis designed to withstand heavy loads. The suspension consists of an independent multi-link setup at both the front and rear, providing a relatively comfortable ride for a heavy-duty truck. Braking duties are handled by disc brakes on all four wheels, coupled with an Anti-lock Braking System (ABS) for enhanced safety. Hydraulic power steering provides responsive handling, although it can feel somewhat heavy at low speeds. The truck’s substantial weight and high center of gravity contribute to noticeable body roll during cornering.
Market Reception & Comparison
The 6.4 Hemi-equipped RAM 2500 received generally positive reviews from automotive critics. It was praised for its powerful engine, comfortable ride, and spacious interior. However, some reviewers noted its relatively low fuel economy compared to the diesel options. In terms of reliability, the 6.4 Hemi has proven to be a fairly dependable engine, although routine maintenance is crucial. Compared to the 5.7L Hemi, the 6.4L offered a significant performance upgrade, justifying the higher price tag for buyers who needed extra power. Against the Cummins diesel, the 6.4L represented a more affordable alternative, albeit with compromises in fuel economy and towing capacity.
Legacy
The 6.4 Hemi V8 has established itself as a reliable and capable engine in the heavy-duty truck market. While newer RAM models have introduced more advanced technologies and powertrains, the 2014-2018 2500/3500 with the 6.4 Hemi remains a popular choice in the used car market. Its robust construction and relatively simple design make it a relatively easy and affordable truck to maintain. These trucks continue to be sought after by buyers who need a powerful and dependable workhorse for towing, hauling, and everyday use. The engine’s longevity and readily available parts contribute to its continued appeal.
