RAM 1500: High Efficiency

by Drew HardinFebruary 11, 2021
The pickup market is hot, motivating automakers to continually deliver new choices and enhancements in their truck offerings. RAM’s 1500 exemplifies this with its latest polar opposites – the mega-high-performance TRX and the 33 mpg high efficiency HFE EcoDiesel shown.

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.
