"There was more towing capacity in the V6 Ram 1500 but we needed to upgrade the transmission to hold the truck and trailer when parked on steep grades," said Mike Cairns, chief engineer at Ram Truck. "Now that we're building the transmissions ourselves, the improvements are included in the new assembly. "
Ram also finalized towing numbers for the exclusive Ram 1500 EcoDiesel. The two-wheel-drive, two-door, long bed with the new EcoDiesel will tow up to 9,200 lb. The new diesel engine approaches larger-displacement V8s' towing capability with a 3.0-liter V6.
Ram is expecting best-in-class fuel efficiency of better than 25 highway miles per gallon from the Ram 1500 EcoDiesel.
