I'd have to wonder if the little coal burner in the Colorado is going to give that torquey, punchy diesel power feeling. I'll agree that driving a newer diesel in a nice pickup is an enjoyable experience, drove my dad's new 6.7 Ford from Oklahoma to South Dakota and he couldn't hardly pry me out of the driver seat. But I have a hunch that the little guy they're sticking in these little trucks will be more reminiscent of driving an old 6.2 as opposed to a Duramax.
