How the eTorque System Benefits the 2019 Ram 1500
The new eTorque engine is really opening up possibilities for the Fiat Chrysler Automobile (FCA) Group. Available in the new 2018 Jeep Wrangler JL and the 2019 Ram 1500, both vehicles received a boost in power thanks to the eTorque system. What we’re all currently wondering is how it works. We know it’s a hybrid system with hybrid capabilities, but what else? What’s different about the eTorque in comparison to the usual vehicle alternator? We’ve covered plenty about the all-new Jeep Wrangler JL, so let’s focus on the 2019 Ram 1500 this round.
What is the eTorque System?
The eTorque system is a new mid-hybrid system that increases fuel economy and produces more torque. Not only is it called a “hybrid” system because it provides the 2019 Ram 1500 with electricity (replacing the need for an alternator), but also offers hybrid capabilities, such as auto stop/start, electric power assist, extended fuel shut-off, transmission shift management, intelligent battery charging, and regenerative braking. Originally, the Ram 1500 generated electricity for its various electrical systems (including the main battery) via a traditional 12-volt battery that keeps a charge via the truck’s alternator (or electrical generator). The eTorque, able to deliver its own electricity to the truck, nullifies the need for an alternator and is able to keep the 12-volt battery charged as well as perform hybrid functions.
That’s not all the eTorque system can do though. The eTorque system is in fact a 48-volt system. In conjunction with the Ram 1500 truck’s electric generator, an eight-rib belt with two tensioners, a DC-to-DC converter, and a battery pack that can store up to 430 watt-hours of energy, the eTorque system is able to convert 12 volts into 48 volts with ease. All-in-all, the system adds about 100 pounds to the truck and is located inside the rear wall of the cabin rather than under the floor, which is where most hybrid systems are located.
How Does the eTorque System Benefit the 2019 Ram 1500?
Alright now, here it gets juicy. The 2019 Ram 1500, at release, will be available with two engine options. The standard is a 3.6-liter Pentastar V6 engine with VVT, able to generate 305 horsepower and 269 lb-ft of torque. With the eTorque system added to that system, the Pentastar V6 engine is able to generate an additional 90 lb-ft of torque in addition to its original output of 269 lb-ft of torque, resulting in over 300 lb-ft of torque for a little more towing power. Because of constraints found with the V6 and the two levels of output, a slightly smaller eTorque system was built for the V6 engine and is installed under the hood.
The next engine in the lineup, a 5.7-liter V8 HEMI engine with VVT, has an even bigger boost of power. Naturally, the legendary V8 can deliver 395 horsepower and 410 lb-ft of torque, but with the eTorque system installed, the V8 gets an additional 130 lb-ft of torque for a total of 530 lb-ft of torque. One can probably attribute the max towing capacity of the 2019 Ram 1500, 12,750 pounds, to that boost in power along with a five-link coil suspension.
The eTorque system also helps with the engineering of the 2019 Ram 1500 due to the stress it takes off of the powertrain as a whole. Not only this, but the eTorque system engages at low speeds, ranging from idle to 1500 rpm. What that means is the eTorque system doesn’t necessarily “add-on” torque but actually broadens the scope of how much torque the 2019 Ram 1500 can generate, even at a standstill. Now that’s real power.
Some may have noticed the acronym at the end of each engine, “VVT.” That stands for “Variable Valve Timing”, technology developed for automotive systems, mainly the engines, to optimize its horsepower and even help with fuel efficiency. This is done by altering the frequency of an engine’s cylinders valve lift events prior to the combustion cycle of the engine. Depending on how this is altered, VVT can have a great effect on engine performance.
Sounds pretty exciting doesn’t it? To think the 2019 Ram 1500 is still a ways away, but we’ll keep everyone updated on Aventura CJDR social media.
