2021 Ram 3500: A Detailed Overview

The 2021 Ram 3500 stands as a titan in the heavy-duty pickup truck segment, engineered for those who demand uncompromising capability and robust performance. Whether tackling demanding worksites, towing substantial loads, or simply seeking an exceptionally capable and comfortable hauler, the Ram 3500 delivers a compelling package.

Highlights

The 2021 Ram 3500 is a force to be reckoned with, offering a potent blend of power, advanced technology, and thoughtful design.

  • Engine Prowess:

    • 6.4L HEMI V8: This gasoline powerhouse delivers a formidable 410 horsepower and 429 lb-ft of torque, providing ample grunt for everyday tasks and heavy hauling. It's paired with an 8-speed automatic transmission.
    • 6.7L Cummins Turbo Diesel I6: The legendary Cummins engine is the star of the show for ultimate capability. It produces a staggering 370 horsepower and an earth-shattering 850 lb-ft of torque, allowing for best-in-class towing and payload capacities. This engine is mated to a responsive 6-speed automatic transmission.
  • Advanced Safety Features: Ram has equipped the 3500 with a suite of advanced driver-assistance systems designed to enhance awareness and mitigate potential hazards:

    • Forward Collision Warning with Active Braking: This system detects potential frontal collisions and can automatically apply the brakes to help avoid or reduce the severity of an impact.
    • Adaptive Cruise Control with Stop & Go: Allows the truck to automatically adjust its speed to maintain a safe following distance from the vehicle ahead, even coming to a complete stop and resuming motion.
    • Lane Keep Assist: Gently guides the vehicle back into its lane if it begins to drift unintentionally.
    • Blind Spot Monitoring: Alerts the driver to vehicles in their blind spots, especially crucial when towing large trailers.
    • Surround View Camera System: Provides a 360-degree view around the truck, making maneuvering in tight spaces significantly easier, particularly with a trailer attached.
  • Trim Level Breakdown: The Ram 3500 offers a diverse range of trims to suit various needs and preferences, each building upon the previous with increasing levels of luxury and capability:

    • Tradesman: The no-nonsense workhorse, focused on durability and essential functionality. Ideal for commercial use and those who prioritize utility above all else.
    • Big Horn: Adds a touch of comfort and convenience features, including upgraded interior materials and exterior accents, making it a more pleasant daily driver.
    • Laramie: A significant step up in luxury, featuring premium interior amenities, advanced infotainment, and more sophisticated exterior styling.
    • Limited Longhorn: This trim blends Western-inspired luxury with rugged capability, offering unique badging, premium leather upholstery, and advanced technology for a sophisticated ownership experience.
    • Limited: The pinnacle of Ram 3500 luxury, this trim boasts the most upscale materials, the latest technology, and a refined interior, rivaling luxury SUVs.
  • Other Notable Aspects:

    • Segment-Leading Ride Comfort: Despite its heavy-duty nature, the Ram 3500, particularly with the available air suspension, offers a remarkably smooth and composed ride, a rarity in this class.
    • Impressive Towing and Payload Capacities: The diesel engine, in particular, allows the Ram 3500 to achieve segment-leading towing capabilities (up to 22,670 lbs when properly equipped) and substantial payload capacity.
    • Refined Interior: Even the lower trims offer a well-built and ergonomic cabin. Higher trims elevate the experience with premium materials, expansive infotainment screens, and advanced connectivity.
    • Available Air Suspension: The optional rear auto-leveling air suspension significantly enhances ride quality and makes hitching up trailers easier.

What to Expect

Owning a 2021 Ram 3500 is an experience geared towards capability and durability.

  • Ownership Experience: The Ram 3500 is built to endure. You can expect a truck that feels substantial on the road, offering immense power and stability when towing or hauling. The cabin provides a comfortable and quiet environment, even at highway speeds, allowing for long-distance journeys to be less fatiguing. Its sheer size and commanding presence are undeniable, making it a vehicle that commands respect on the road.
  • Maintenance: As a heavy-duty truck, the Ram 3500's maintenance schedule will be more rigorous than a standard passenger vehicle. Regular oil changes, filter replacements, and fluid checks are crucial, especially for the powerful diesel engine. Diesel owners can expect more specialized maintenance, including potential DEF (Diesel Exhaust Fluid) refills. Tire rotations and brake inspections are also critical due to the stresses of heavy hauling. It's advisable to follow the manufacturer's recommended service intervals closely and utilize qualified mechanics familiar with heavy-duty trucks.
  • Insurance: Due to its higher purchase price, powerful engines, and advanced features, insurance premiums for the Ram 3500 will generally be higher than for smaller vehicles. Factors like your driving record, location, chosen coverage levels, and the specific trim and engine you select will significantly impact the cost. It's recommended to get insurance quotes early in the buying process to factor this into your budget.

Potential Considerations

While the Ram 3500 excels in many areas, there are a few aspects buyers should be aware of.

  • Maneuverability in Tight Spaces: Its sheer size and long wheelbase, while beneficial for stability, can make navigating tight city streets, parking garages, and crowded lots a challenge. A surround-view camera system and parking sensors are highly recommended for easier maneuvering.
  • Fuel Economy: Especially when equipped with the powerful diesel engine and used for heavy towing, fuel economy will naturally be lower than that of lighter trucks or SUVs. While the diesel offers better MPG than the gasoline V8, it's still a thirsty powertrain designed for work.
  • Entry and Exit: Getting into and out of the higher trims, particularly with the added height of the truck, can be a minor challenge for some individuals, especially those with mobility issues. Running boards or side steps are almost essential for easier access.
  • Ride with No Load: While the air suspension significantly improves comfort, even then, without a load in the bed, a heavy-duty truck can still feel a bit firmer or bouncier than a half-ton pickup.

Overall Summary

The 2021 Ram 3500 is a masterclass in heavy-duty truck engineering. It offers a potent combination of class-leading towing and payload capabilities, particularly with its formidable Cummins diesel engine. Beyond its raw power, it delivers a surprisingly refined and comfortable ride for its class, bolstered by a well-appointed interior and a host of advanced technology and safety features. While its size and fuel consumption are inherent considerations for any heavy-duty vehicle, for those who require uncompromising strength and capability for demanding tasks, the Ram 3500 stands as a highly competent and desirable choice in the Super Duty segment.
