The eTorque in my 21 RAM Limited was AWESOME!The only “good” implementation of auto stop/start is with Ram’s E-Torque system.
The electric motor/generator that replaces the alternator physically spins the engine to drive the wheels. Once up to speed, the plugs fire and fuel injects.
It’s the only way the system works effectively in a large v8 application.
It’s very smooth compared to the shuttering mess of basically neutral dropping the truck if you press the gas at a light.
