Functionally, eTorque works by replacing the RAM’s conventional alternator with a more robust motor/generator in 3.6-liter V-6 and 5.7-liter V-8 HEMI engines. The eTorque-equipped V-6 mounts its Continental motor-generator in front of the engine with the pulley pointing aft.

The name “eTorque” would suggest that it’s some kind of electrical system that boosts torque for a truck you’d find at the Ram dealer near you, and that’s more-or-less a reasonably accurate description of it. Essentially, an engine with eTorque has an electric motor that boosts torque, thereby improving performance with that vehicle.

The RAM 1500 eTorque engine option is a mild hybrid system that replaces the traditional alternator with a 48-volt battery-power, belt-drive motor generator. This increases performance, efficiency, payload, and towing capabilities.

The eTorque system is essentially a mild hybrid system that replaces the alternator with a belt driven generator that performs several different functions. The goal of this system was to improve performance, fuel economy, payload, towing capabilities and drivability.
