According to PickupTrucks.com GM is indeed considering reviving the 4.5 liter Duramax V8 diesel. Apparently some within GM are wondering if the shelved engine should be put back on the road map. The reality is with higher fuel economy laws going into effect in the future, more efficient engines must play a role. Diesel is more efficient and will get better fuel economy. This will help with the fleet average for GM, specifically in the truck segment. Of course cost is a factor and the V8 Duramax would have a cost premium over the standard 6.0 liter gasoline V8 in the Heavy Duty trucks currently. The question is how much less could the 4.5 liter Duramax cost then the $8,395 6.6 liter Duaramax? I would say, offer it in both the 2500 Heavy Duty’s and the 1500 pickups and that would make the world make sense. I could easily see at the right price point 1500’s selling with Diesel engines.
