It has more torque than the 5.7, so likely the towing rating is governed more by other factors and not by the engine. Gear ratio, transmission, brakes, cooling and electrical systems, all play a part in towing rating.LtjimT said:The big questions to be answered (for me) are its mileage rating, payload, and tow capacity. It should provide very good mileage, particularily on the highway. It may have a negative effect on payload as an article in one of the mags indicated about 100 lb increase for exhaust tx and def system (over hemi/8spd). When the 2014 owners manual was on line briefly I believe the max tow number was lower than hemi/ 8-speed. Will 3.92 rearend ratio be available? Hopefull this information will be available soon. Name doesn't bother me. :thumbsup:
That hundred lbs is easily overcome by the higher torque rating, however if the rating is lower, it's primarily because they want to start out conservatively. The fuel economy improvement will be the main selling point.
