It appears as if they small-bore diesel wars are set to swing into full motion come next year. We already know about the 4.4-liter Ford diesel V8, which comes from Ford's Euro side, and the 4.5-liter Duramax V8 from the General. Now, we find that the upcoming 2010 Dodge Ram - rumored to get a small-bore oil-burner of its own - may very well come with an optional 5.0-liter V8 from Cummins. This revelation comes courtesy of Mike Levine and his minions over at PickupTrucks.com who noticed an underhood sticker for the proper refilling of refrigerant on the air-conditioning unit. It takes real dedication to notice such a thing, but it has definitely paid dividends this time. Along with what is sure to be a fairly sizable increase in cost, the smaller-displacement diesel engines should each offer well over 500 lb.-ft. of torque along with a 25-percent improvement in fuel consumption. That's what we like to hear.
