Thanks to some keen observation by Mike Levine, we now have a strong indication as to the displacement of the upcoming diesel engine for the 2010 Dodge Ram 1500. Under the hood of the 2009 Dodge Ram 1500 pickup is a sticker that dictates the proper amount of air conditioning refrigerant. The sticker lists, in addition to the available 6.7-liter I-6 turbo-diesel for the 2500 and 3500 models, a 5.0-liter turbo-diesel engine as a possibility. This suggests that the 2010 Dodge Ram 1500 will offer a 5.0-liter V-8 turbo-diesel engine.
This development would put the Dodge Ram 1500 diesel into direct competition with the upcoming 4.5-liter turbo-diesel V-8 from General Motors and the 4.4-liter turbo-diesel V-8 for Ford’s F-Series trucks.
Early in the year, Chrysler announced that its diesel-powered Ram half-ton pickup would be released by 2010. The diesel is expected to improve fuel economy by 25 percent.
