The new 2013 Ram Heavy Duty line features best-in-class towing and best-in-class Gross Combined Weight Rating (GCWR), according to a Chrysler announcement Sept. 27. Ram 2500 and 3500 Heavy Duty trucks also add new features, including an all-new interior, next-generation Uconnect Access, Powernet, new frames and new suspension.

Engineering

For 2013, Ram Heavy Duty trucks feature new frames built with high-strength 50 KSI steel, including eight separate cross-members, hydroformed main rails and fully boxed rear rails for optimal strength and mass efficiency. In the rear portion of the new frame, the structure includes fully boxed rear rails and a factory-installed rear axle cross member with provisions for 5th-wheel and gooseneck hitches.

A new conventional trailer hitch system is upgraded to Class 5 with a 17,000-lb. load capability and 1,800 pounds of tongue weight for use with 2-inch or 2.5-inch receiver hitches.

An advanced three-link front suspension on the Ram 3500 is necessary for the vehicle’s higher GVWR and for use with heavy front loads, including snow plows. Additionally, a newly designed Hotchkiss leaf spring rear suspension on the Ram 3500 offers improved ride and handling while delivering higher towing and payload capability, according to Chrysler.

A number of body improvements have been made to enhance overall noise, vibration and harshness (NVH). The new truck comes equipped with an updated engine, transmission and body mounts, including hydro-mounts at C-pillar positions for class-leading NVH characteristics despite the truck’s aptitude for higher payloads and towing.

A new capless fuel filler on diesel applications is a space-saving initiative that enables side-by-side fuel and diesel exhaust fluid (DEF) port configuration.

The Ram 3500 features a factory-installed trailer tow connector in the truck bed, included with the optional 5th wheel or gooseneck tow prep package. New structural support is designed into the body to support the payload increase and improve durability performance. Additionally, new reinforced tie-down points with enhanced strength are designed for heavier loads.

Electrical

The new Ram Heavy Duty now features the Powernet electrical architecture system allowing both high and low-speed data networks to be equipped with as many as 40 individual modules, all designed to improve vehicle performance and enhance the comfort and safety of driver and passengers.

A new vehicle system interface module (VSIM) is capable of communicating between aftermarket modules and various factory control modules. The VSIM up-fitter interface module features a total of 72 inputs and outputs, including lighting controls, door position and throttle and transmission position. The class exclusive module acts as a secure gateway to the vehicles’ electrical system.

New for 2013, central locking includes the RamBox cargo management system and tailgate power locks, creating a convenient solution for locking all exterior doors and storage with one push of a button. Auto rain-sensing wipers and SmartBeam headlamps also find their way into the feature availability list of the new 2013 Ram Heavy Duty.

Powertrain

For 2013, the 5.7-liter HEMI V-8 makes its debut in Ram 3500 Heavy Duty pickup as standard equipment (single rear wheel). Also standard in the Ram 2500 Heavy Duty, the engine produces 383 horsepower at 5,600 rpm and generates peak torque of 400 lb.-ft. at 3,950 rpm. The HEMI V-8 is mated to a 66RFE six-speed automatic transmission.

The renowned 6.7-liter Cummins High-Output Turbo Diesel I-6 is now available in three versions:

  1. The first version is paired with Ram’s six-speed manual transmission, which features a wear-compensating clutch for lifetime “like-new” performance and a dual-trunion shift tower to accommodate a compact shift pattern. This combination delivers 350 horsepower at 2,800 rpm and 660 lb.-ft. of torque at 1,500 rpm — a significant boost from the 2012 model-year maximum of 600 lb.-ft.
  2. The second option matches the Cummins to the 68RFE six-speed automatic transmission. The diesel engine cranks out 370 horsepower at 2,800 rpm with an unsurpassed in ¾-ton trucks 800 lb.-ft. of torque at 1,600 rpm.
  3. Finally, an upgraded 6.7-liter Cummins High-Output Turbo Diesel I-6 for Ram 3500 is paired with a new Aisin six-speed automatic transmission (AS69RC). In addition to 385 horsepower at 2,800 rpm, the most powerful Cummins generates best-in-class torque of 850 lb.-ft. at 1,600 rpm. The new AS69RC transmission features wide gear ratios that contribute to upgraded shift performance, an approximate 1% gain in transmission efficiency and improved driveability when compared to the previous design.

For 2013, all Ram Heavy Duty diesels benefit from an all-new cooling system. A high-efficiency fan, dual radiators, dual transmission coolers and charge air cooler afford 25% more heat-rejection capacity. Lower operating temperatures deliver improved performance, durability and lower operating costs.

Diesel-equipped Ram Heavy Duty pickups feature an industry-exclusive Ram Active Air intake system, activated by new monitoring capabilities added to the engine controller. When the intake system senses extreme heat, it draws cool air from the front of the vehicle — a function that also engages at high altitudes for superior throttle response in low oxygen environments. When conditions are wet from snow, ice or water-fording, the system pulls air from an underhood inlet clear from snow packing and water ingestion.

The Cummins powerplants benefit from a larger exhaust-gas recirculation (EGR) cooler, which complements the debut of selective catalytic reduction (SCR) and accommodates a best-in-class oil-change interval of 15,000 miles. Oil life is increased by reducing soot production and reducing fuel dilution of the oil.

Combined with a 10% improvement in fuel economy due in part to the engines’ high-pressure common-rail fuel system, SCR promises a net reduction in Ram Heavy Duty operating costs. The SCR-equipped diesels, which can run on B-20 biofuel, also operate cleaner by lowering greenhouse-gas emissions and better managing soot production than Lean NOx Trap (LNT) technology.
