CHELSEA, MICHIGAN — Chrysler’s Ram division is launching a new, 6.4-liter gas V-8, based on the Hemi architecture, as the standard engine in its new 2500 and 3500 heavy duty trucks. The engine is rated 410 horsepower and 429 pound-feet of torque. With no degredation in hauling/towing capability versus Ram’s Cummins Diesel engine option, the big gas V-8 brings cylinder deactivation to the big trucks.
Ram also announced that the ’14 2500 gets the five-link coil suspension that was added to the Ram 1500 for 2009. With four trailing arms, two coil links and a track bar, the rear suspension is designed to give the big truck better ride quality and greater roll stiffness without degrading payload, says Heavy Duty engineering chief Kevin Mets.
You could describe it, Mets says, as “holy cow.”
Both the 2500 and leaf-spring 3500 will be available with optional air suspension featuring normal and trailer modes.
Meanwhile, Ram is preparing its new VM Motori-supplied 3.0-liter diesel V-6 for application in the 1500 beginning this fall. The EcoDiesel V-6 option will cost $2850 more than a Hemi 1500, says marketing chief Bob Hegbloom, and will exceed the 3.6-liter gas V-6/eight-speed automatic truck’s EPA highway mileage estimate of 25 mpg.
“We’ve been looking at it for years, and finally we’re doing it,” he says.
