Great 5th Gen Rams article here, but there is also one from MotorTrend that answers some long-standing questions and gives a few other tidbits:

Should Ram have made a badge on the car to indicate hybrid? Almost goes against the engineering to make it seamless.
Is the AC pulley smaller to compensate for the larger crankshaft pulley?

- V6 eTorque is water cooled because the generator sits backwards in the bay and thus can't be air cooled. It's also heavier than the V8 implementation due to the water cooling (V6 120 lbs, V8 90 lbs). [Update - several other pubs list the V6 eTorque weight at 105 lbs so we'll have to see what's correct.]
- Under fast brake to acceleration, eTorque can provide up to 1/2 of the tire rotation
- System can power car from 48V battery rather than increasing generator load to improve economy
- V6 system is made by Continental and rated at 12hp
- V8 system is made by Magneti Marelli
- LG Chem makes the battery cells and battery pack weighs 30 lbs. Pack rated at 430 whr but only ever uses 130 whrs to ensure long life.
- 48V system to stay below 50V "high voltage" threshold
- Wider 8-rib belt with tensioners on both sides of it
- eTorque models have a larger crankshaft pulley
- eTorque detects any belt slippage due to water and compensates until dry. Belt rated for 10y/150,000 miles.
