eTorque is a technology used in some Ram and Jeep vehicles that enhances torque delivery and improves performance and efficiency. It is a mild hybrid system that replaces the traditional alternator with a more robust motor/generator that provides a brief torque boost of 90 lb-ft in V-6 RAMs and 130 lb-ft in V-8 models. The eTorque-equipped V-6 mounts its Continental motor-generator in front of the engine with the pulley pointing aft, and a dedicated, water-cooled coolant circuit is used since the internal cooling fans in a typical alternator would not work in this configuration. The eTorque motor/generator begins to generate electrical energy that feeds back to its battery pack while also smoothing transmission downshifts when lifting off the throttle at speed. It also contributes torque while transitioning in and out of four-cylinder mode during V-8 cylinder deactivation. The eTorque option is a standard on the 3.6-liter Pentastar V6 and an available option on the 5.7-liter HEMI V8.
