Hemi goes hybrid: the 2019 Ram 1500's revolutionary eTorque System | Steve Landers Auto Group


Everybody knows that when you’re towing our hauling, torque is king. With the heaviest loads, having plentiful low-end torque on tap can be the difference between getting the job done and sitting on the side of the road with the hood up, waiting for a tow of your own. Ponying up for a pricier, torquier turbodiesel is an option, but with naturally-aspirated gasoline engines, it usually takes quite a few cubic inches, and a corresponding dip in fuel economy, to make them post the big torque numbers that make hauling and towing a breeze, and from idle to 1,500 rpm -- where you need torque the most when taking off with a load from a stoplight or pulling a boat out of the water -- gasoline engines are usually the pits no matter how big your block.  

Luckily for you, the engineers at Ram are always thinking of new ways to make the Ram 1500 tougher, stronger and more reliable. On the all-new 2019 Ram, one of the ways they found to do that is the new eTorque system, which provides up to 130 lb.-ft. of additional low-end torque on demand, with zero effect on overall gas mileage. Given that there’s no free lunch in this world, how is that possible? Read on to learn the details on this incredible new technology from Ram, which has already made its way to the engine bay of Ram’s Fiat-Chrysler stablemate the 2018 Jeep Wrangler JL. Come see us at Steve Landers Auto Group’s Chrysler Dodge Jeep Ram locations in Little Rock, Ark. and Norman, Okla. to check out the new 2019 Ram 1500 for yourself, or shop our big inventory of 2019 Ram 1500’s online!

Free torque with eTorque

Though the words “hybrid vehicle” may conjure up images of dead-silent, jelly bean-shaped commuter cars with engineering more focused on increasing the number of cupholders than boosting towing capability, the eTorque system, in effect, turns the 2019 Ram 1500 into a gasoline-electric hybrid. Ram calls it a “mild-hybrid” system, meaning it only supplements the 2019 Ram’s normal gasoline V6 and V8 engines. It starts with replacing the traditional alternator with a compact, 48-volt electric generator that’s mounted to the engine and belt-driven by the crankshaft. In the photo of a 5.7-liter Hemi seen above, the eTorque generator is the squared off, belt-driven device mounted just in front of the “Hemi” engine cover.


In addition to keeping the regular 12-volt truck battery charged, starting the engine in less than four tenths of a second to allow for Ram’s start/stop fuel efficiency system (which turns off the 2019 Ram every time it comes to a complete stop), and powering the 2019 Ram 1500’s standard 12-volt electrical systems via a step-down DC-to-DC converter, during normal driving, the eTorque system sends extra electricity that would normally be wasted to a suitcase-sized battery pack hidden in the back wall of the cab. That battery can store up to 430 watt-hours of energy, and is constantly being topped off by the generator when extra torque isn’t required. The battery pack, cables, generator and other eTorque components add around 100 pounds to the weight of a 2019 Ram 1500, but thanks to the use of lighter, high-strength steel and military-grade aluminum alloy in body panels and certain chassis components, the 2019 Ram weighs around 225 pounds less than the previous model. Too, the results are worth a little extra weight.


When the 2019 Ram 1500’s sophisticated computer systems sense a load between idle and 1,500 rpm -- the range where gasoline engines produce the least amount of torque, and where you need it most when taking off from a stop while towing or hauling --  the eTorque generator instantly switches from sending power to the battery pack and becomes a powerful electric motor, drawing power from the battery pack and sending gobs of free, tow-friendly torque directly to the crankshaft through the same high-strength belt that normally drives the system. In the 2019 Ram’s standard 3.6-liter V6, which is already putting out 305 hp and 269 lb-ft. of torque, the system is good for an additional 90 lb.-ft. of torque when you need it. In the Ram 1500’s 395 hp, 410 lb.-ft. 5.7-liter Hemi, eTorque delivers a whopping 130 lb.-ft. of torque on demand. That not only helps out while towing, it takes stress and strain off of critical engine components, helping your new Ram last longer. It’s also good for an estimated 10 percent improvement in fuel economy numbers. The system is standard on the V6, and optional on the V8

When you think about it, eTorque is pretty incredible, not to mention one of those “why didn’t they think of this before?” ideas that will make towing a trailer, a boat or RV easier and safer than ever. The eTorque system is just one of the hundreds of ways the top-to-bottom redesigned 2019 Ram 1500 is stronger, better, tougher and more technologically advanced than ever before. It’s the best Ram truck ever, and we think one test drive is all it will take for you to agree.
