Getting the 2019 Ram 3500 to a class topping 1,000 lb.-ft. of torque and 35,100 pounds of towing took plenty of careful engineering.
To help explain the changes made to their top workhorse, Ram placed a color-coded chassis on display at the North American International Auto Show that quickly shows where new components were used to cut weight, add strength and reduce noise.
In the video below, Rod Romain, chief engineer of Ram heavy-duty trucks, not only addresses the changes to the chassis but to the powertrain and front clip. Hard work paid off as the 2019 Ram 3500 not only reached a historic level of torque, but also shed 143 pounds from the prior model and saw air drag reduced by eight percent.
Some of the weight loss came through a graphite iron block found at the heart of the Cummins I6 6.7-liter Turbo Diesel V8.
“That’s 75 percent stronger,” Romain says of graphite iron. “It’s also lighter and it’s also quieter.”
