For Dodge's advertising campaign, the Ram 1500 has been labeled the "Mayor of Truckville." For the new heavy-duty Rams, we suspect the title "Overlord of Truckville" is fitting. It was at the 2001 Chicago Auto Show that Dodge introduced its new Ram, so it seems fitting that the heavies made their debut one year later at the same location. Armed with new powertrains, massive tow and payload capacities, updated Ram styling and plenty of features, the 2500 and 3500 trucks should be quite attractive to commercial users, as well as serious consumers. Starting things off are two new engines. The first is 5.7-liter V8. Called "Hemi Magnum," it marks the return of Chrysler's legendary Hemi engine name after a 32-year absence in Chrysler production cars. This new V8 is standard in both Rams and features a hemispherical combustion chamber (hence the name Hemi). It makes 345 hp and 365 lb-ft of torque, more than GM's 6.0-liter V8. The other new motivator is a high-output Cummins turbo diesel. This 5.9-liter inline six puts out 305 hp and a towering 555 lb-ft of torque. The high-output Cummins is optional in the 2500 and 3500, as are last year's 8.0-liter gas V10 and regular Cummins turbo diesel. A variety of transmissions are available (including a new five-speed automatic), as is manually or electronically controlled 4WD. Four-wheel-drive trucks will have a live front axle, as opposed to the Ram 1500's independent front suspension. Regular and four-door Quad Cab body styles are available. For the first time, a two-wheeled rear-axle 3500 is available, providing an intermediate step in payload capacity between the 2500 and 3500 dually. Thanks to an exceptionally stiff frame and a new rear axle, towing and hauling capacities are quite high. A Ram 3500 dually with the HO Cummins has a 12,000-pound max payload (GVWR) rating and 23,000-pound tow rating (GCWR). Dodge says it created a new duty cycle aimed directly at commercial customers, testing the new Ram in conditions ranging from -40 to 130 degrees F and running the equivalent of 150,000 miles at 95 percent of their maximum towing and payload ratings. Safety is also enhanced with the new truck, thanks to features like side curtain airbags, power adjustable pedals and seatbelt pre-tensioners. ABS is standard. Do you like trucks? Do you like trucks that can haul huge horse trailers? How about trucks that cause Honda Civics to wilt out of the fast lane as soon as they get a glimpse of an oversized big-rig grille and flared dually fenders? If you answered yes to these questions, the Ram 2500 and 3500 are just begging for homes in your driveway.
