The USS Seawolf attack submarine is supposed to be so quiet that it can only be recognized by listening for the absence of noise. That's a pretty big job and one that we remembered when we wanted to see the mild hybrid electric assist engine's activity in the Ram 1500 eTorque Pickups 2019.
The system is so quiet and invisible seamlessly that it looks for signs of its activation seems destined to fail. The same goes for the cylinder deactivation system, which runs the optional 5.7-liter V-8 engine on four cylinders to save fuel.

No more. With Ram's sophisticated vibration control technology and the unpleasant sounds of a 90-degree V-4 engine, the Hemi can now run smoothly on four cylinders. The Ram features active vibration dampers mounted on the frame rails of the truck and noise cancellation technology with the car's audio speakers to eliminate unwanted noise and vibration from the engine's fuel efficient 4-cylinder mode

For 2019, Ram 1500 is available with a range of three different powertrains. The base system is the familiar 305-hp, 269 lb-foot. 3.6-liter V6 petrol engine found on virtually every model of the company's product line. Now, however, it is equipped with a 9kW belt generator mild hybrid system that can deliver a seamless 90 lb electric boost at launch to start the ram off the line.
This device is an enlarged generator but with much more capacity to generate power and the ability to return it to the engine through its drive belt. Ram's vehicle electrification manager Brian Spohn gives way to the idea that such a device, which is bolted to an existing gasoline engine, is a simple "plug-in" upgrade.

"There are so much integration work goes on, that's far from being "bolt-on," he said.
This system also stops and restarts the gasoline engine when the truck is stopped, turning the engine upright in 70 milliseconds and bringing the gas engine online in 400 ms. This means that the electric motor almost immediately pushes the truck forward and the gas engine engages within about half a turn of the wheels.
Perhaps the coolest aspect of the 3.6-liter V-6 with eTorque, as it's officially called, it's the base engine of the Ram 1500, which fueled buyers for the $ 33,340 (including $ 1,645 destination fee) Entry-level trucks brings benefits for fuel economy.
Unlike some hybrids battery pack does not take up valuable interior space. The backpack of the ram is about the size of a cutlery box and is attached to the rear wall of the cab behind the back seat in a room that would otherwise be unused. It contains a dozen LG Chem battery cells to provide the system's 430 watt-hours of 48-volt power.
The 395-horsepower, 5.7-liter Gas V-8 engine is the next step in the Ram 1500 line, a familiar and well-regarded engine that adds $ 1,195 to the price of the truck.
The new top option is the electrified eTorque-equipped version of the V-8 for an additional $ 800. This engine has the same performance as the gas-only version, as the hybrid system only supports the Start-Oomph, so that its performance is not reflected by the peak power of the engine. The V-8 has a stronger belt-generator system than the V-6, with 12 kW of power and 130 lb-ft for engine restarts and vehicle starts.
