Klegon also noted that just as the Hemi V8 enhances Dodge’s image
in light-duty vehicles, its use of Cummins turbo diesel engines in its
work vehicles is something that resonates well with commercial buyers,
who, he noted, appreciate the fact that it’s 350,000 miles to overhaul.
Powering the new 4500 and 5500 trucks is a 6.7-liter Cummins turbo diesel
that converts the new low-sulfur fuel into 305 horsepower (at 2900 rpm)
and, more significantly, 610 pound-feet of torque at just 1600 rpm.
By the way, the trucks also run on B5 bio-diesel. In fact, they leave
the assembly plant with their 52-gallon fuel tanks full of B5.
new big trucks, Klegon added, meet heavy-duty vehicle emission standards
in all 50 states.
Six-speed manual or automatic transmissions have Power Take Off capability
and what Dodge promises is the best-in-class first-gear launch.
Dodge also brags that the brake rotors and caliper piston size are the
largest in the segment, and that brake life is extended by a standard
factory-installed diesel exhaust brake system.
The 4500 and 5500 Rams also built with 50,000-psi steel to increase strength
and reduce weight and that chassis components are positioned below the
top of the frame surface to facilitate aftermarket up fitting.
The Dodge display here in Chicago highlighted that fact by showcasing
the 4500 and 5500 with various dump, tilt and cargo-carrying equipment
mounted behind the cab.
