The 6.6 is certainly capable of medium duty. They used them in their medium duty trucks from 03 to 08,and I own a 5500 4x4 CC and pull the to max gvw everyday. The new medium duty trucks will have the newer Duramax in them when they release in 2017, not sure what power rating they will have. Likely derated from the 3500
I would say the engines will be Navistar or Isuzu, which they stated they will be having some Isuzu rebranded trucks To use them as MDT's the 6.6 was putting out 300hp and 500lbs ft of torque, in the TopKick , a lot less than the 3/4 ton specification
What GM is looking for is a F650/F750 competitor, Isuzu with it's Light Trucks to us but (you call them Medium,) will cater for the straight delivery function. Navistar can provide those sort of Trucks, just like it did with Ford.
The 300 hp and 550 foot pounds was identical to the LB7 Duramax spec offered in 3/4 and 1 ton pickups. You are right however that they are detuned for medium duty, which is common due to the duty cycle of the heavier truck. Mine is an LLY with the 300/550 spec (which is lower than an LLY pickup of the same vintage. However it runs 5:19 gear ratio, pulls whatever you want. The engines and drivetrains of the Navistar truck will be GM.
