According to Gary Arvan a GM Diesel powertrain engineering chief the two biggest changes will be the new selective catalytic reduction and its enhanced exhaust gas recirculation systems. It will also use B20 biodiesel, which is 80 percent ultra-low-sulfer diesel and twenty percent biodiesel. The new engine will also make better use of exhaust gas recirculation across the Duramax’s power band than did the previous engine. Arvan also stated that the new engines would not let the new regulations keep them from producing enough power. The heavy duty trucks will definitely still have the 360 hp and 660 pounds-feet of torque that todays engine has. However many people believe that there will be a nice increase in power when the numbers are revealed. Probably everyone’s question is whether or not the gas mileage will get better or worse, as of right now it looks it will remain the same.
