With the debut of a new high-efficiency Tradesman HFE EcoDiesel, the 2021 RAM 1500 full-size pickup can now be ordered in 11 different models and five engine options, two bed lengths, two cab configurations, and two- and four-wheel-drive powertrains. Whew! The five engines span a wide range of output and efficiency metrics, from the 6.2-liter, 702-horsepower supercharged Hemi V-8 in the newly introduced ‘Apex Predator’ TRX model to V-6 and V-8 mild-hybrid gas engines and a 3.0-liter turbodiesel.
The Italian-made EcoDiesel V-6, now in its third generation, features aluminum cylinder heads and dual overhead camshafts with four valves per cylinder. Induction is via high-pressure, direct-injection nozzles, while a water-cooled, variable-geometry turbine provides boost. The engine is rated at 260 horsepower and 480 lb-ft torque, has earned 22 city/32 highway mpg, and has a towing capacity of up to 12,560 pounds. The new Tradesman HFE EcoDiesel variant ups the ante to an unsurpassed 33 highway mpg, in a model that starts at $42,240
The mild-hybrid eTorque versions of the 3.6-liter Pentastar V-6 and 5.7-liter Hemi V-8 replace the standard engine alternator with a belt-driven motor-generator. Working with a 48-volt, 430 kWh lithium-ion nickel-manganese-cobalt battery pack, the motor-generator enables the engines’ stop/start function and brake-energy regeneration, and it provides short bursts of torque under certain driving conditions. The air-cooled battery pack is mounted to the back wall of the RAM's cab.
The eTorque Pentastar V-6 produces 305 horsepower and 269 lb-ft torque and is EPA rated at 20 city/25 highway mpg. The eTorque Hemi V-8 puts out 395 horsepower and 410 lb-ft torque and has earned 17 city/23 highway mpg ratings. By comparison, the 5.7-liter Hemi V-8 without eTorque assist has the same output ratings but lower fuel economy: 15 city/22 highway mpg. All these engines route their power through eight-speed TorqueFlite automatic transmissions.
New and improved driver aids available on the 2021 RAM 1500 include a full-color head-up display that can show up to five content areas at once; a digital rearview mirror that displays real-time video from a rear-facing camera (but can revert back to a traditional reflective mirror); and trailer-reverse steering control, which allows the driver to turn a dashboard-mounted dial in the intended direction of the trailer (handing the actual steering control to the system). Adaptive cruise control, forward-collision warning, blind-spot monitoring and pedestrian detection are also among the safety and security features available for the RAM.
The RAM 1500 remains the only light-duty full-size pickup in the segment with a coil-spring rear suspension system, which the maker says improves ride and handling while not compromising towing or hauling capacity. Buyers will find entry-level RAM 1500s starting at $32,595 and rising upward, with the high-performance TRX topping out the lineup at $70,095.
