  • Wrangler and Ram Go Hybrid

March 24, 2018 – The new generations of the Ram 1500 and Jeep Wrangler will be available with a new feature: eTorque, FCA’s mild hybrid system.

The eTorque mild hybrid system replaces a conventional engine’s alternator with a belt-driven motor generator that works with a 48-volt battery pack. This technology enables quick and seamless start/stop function, short-duration torque addition to the engine crankshaft in certain driving situations, and brake-energy regeneration, which improves responsiveness and efficiency. With the engine running, eTorque’s motor generator unit feeds 48-volt current to a 430 watt-hour lithium-ion Nickel Manganese Cobalt (NMC)-Graphite battery. The battery pack includes a 3-kilowatt DC-to- DC converter to maintain the battery’s state of charge and convert 48 volts to 12 volts to power accessories and charge the vehicle’s 12-volt lead-acid battery. The eTorque motor generator is slightly different between the 3.6-liter Pentastar V-6 and 5.7-liter HEMI V-8 applications. The Pentastar eTorque unit is liquid cooled and mounted on the front of the engine. The HEMI V-8 eTorque unit is air cooled and mounted top-side.
