2010 Dodge Ram 2500 Heavy Duty

The Dodge Ram Heavy Duty is the first to market, and it’s already ahead of the game. When Ford and GM’s all-new heavy-dutys come out, both new diesel engines are going to require urea injection to meet emissions requirements that take effect January 2010. The Ram Heavy Duty’s Cummins inline-six turbodiesel, which puts out an impressive 350 horsepower and 650 pound-feet of torque, met those requirements — without urea — over a year ago.

The Ram 2500 and 3500 use a NOx adsorber with precious metals that convert the NOx into inert gases. Not only does this mean the Ram’s emissions and exhaust systems are less complex than those in the upcoming Ford Super Duty and Silverado/Sierra HD (which could improve reliability and help keep maintenance costs down), it also means that, at the dealership, the Ram will very likely have a price advantage over its competitors.

And while in this size category diesel is king, there are plenty of heavy-duty truck buyers who prefer gas power. The 5.7-liter Hemi, the Ram’s base engine, has the most horsepower (383) and torque (400 pound-feet) of any V-8 in its class — and only the Ford Super Duty’s V-10 has more torque than the Hemi, but it still has less horsepower.
