USS Seawolf attack submarine is said to be so quiet that the only way to discover it is to listen for the absence of sound. It's a pretty high order and one we remembered while trying to separate the activity of the mild hybrid electric auxiliary engine in the 2019 Ram 1500 eTorque pickups.
The system is so quiet and so invisible seamlessly that it searched for signs of activation seems to be doomed to fail. The same goes for cylinder deactivation that allows the optional 5.7-liter V-8 engine to run on four cylinders to save fuel.

No more. Hemi can now drive on four cylinders as steadily as eight thanks to Ram's sophisticated technical solutions to suppress vibration and unhealthy sounds produced by a 90-degree V-4 engine. Ram has active vibration dampers mounted on the truck's frame rails and noise reduction technology using the truck's audio speakers to cancel unwanted noise and vibration from the engine's fuel-saving 4-cylinder ring mode.

In 2019, Ram 1500 is available with a variety of three different driving straps. The basic system is the famous 305-horsepower, 269 pound-foot. 3.6-liter V-6 petrol engine depicts almost all models in the company's product line. Now, however, it is equipped with a 9-kw belt-alternator-mild hybrid system that is capable of transmitting 90 pound-felt seamless electric power at start to help the frame of the line.
This device is an enlarged generator, but with much greater capacity to generate power, as well as the ability to return it to the motor through the drive belt. Ram's Vehicle Electrification Manager Brian Spohn flinches at the idea that such a device bolted to an existing gasoline engine is a simple bolt-on upgrade.
