Dodge Ram 3500HD

When it comes to consumer loyalty, you’d be hard pressed to find a more dedicated group of fans outside the heavy-duty pickup segment. Recognizing this, Dodge has brought a slew of full-size trucks to the Chicago Auto Show in the form of the 2010 Dodge Ram 3500, 4500 and 5500 HD Chassis Cabs.

Dodge started the heavy-duty retrofit with the highly-competent 1500 model introduced last year, then proceeded to create a crew cab variant that’s claimed to be packing the most room in its class. Both regular and Mega Cab variants will be offered, along with two bed sizes (six-foot, four-inch or eight-foot) and five trim levels: ST, SLT, TRX, Laramie and Power Wagon.

Pickup aficionados will notice the new bumper treatment, larger grille (with chrome, black or body-colored trim), wider fenders for the dually models and the subtle tailgate lip to improve aerodynamics.

The HD comes standard with Dodge’s HEMI 5.7-liter V8, putting out 383 hp and 400 lb-ft of torque through a beefed-up 545RFE five-speed automatic. However, with a take-rate of over 90% for the diesel engine on HD models, Dodge is offering the optional 6.7-liter Cummins inline-six that channels 350 hp and 650 lb-ft of torque to a 68RFE six-speed automatic featuring low-speed "creeper" mode and Electronic Range Select, allowing the driver to limit which high gear is used while towing. Two 4×4 models will be offered, along with four different axle ratios, and on the topic of towing, the Ram 3500 HD, equipped with the Cummins turbodiesel, dual rear wheels, 4×4 system and a 4.10 rear axle ratio can handle a maximum payload of 5,110 pounds and a towing capacity of 18,500 pounds. Sales will begin this fall
