The Peterbilt Model 379 is the first production truck available with the 600- and 625-hp. versions of Caterpillar's C15 engine, according to Peterbilt Motors general manager and PACCAR VP Dan Sobic. The new Cat is being offered in the Model 379X and Model 379-127 for heavy haul and other applications looking for high-horsepower performance.
The company also announced that it's expanded its offering of Allison automatic transmissions to all heavy-duty models equipped with Cummins or Caterpillar engines. The heavy-duty line also gets a new seating option, the Bostrom Wide Ride. Longer and wider, the air-suspension seat is available in a high-back version or mid-back with headrest, in either leather or fabric.
Moving down to its medium-duty Model 335, Pete has added the two-pedal 6-speed Eaton Ultrashift transmission as an option. The automated mechanical transmission can be paired with either the Cummins ISC or Caterpillar C7 diesels.
Pete also announced that Dupont Imron Elite paints are now standard on all of its trucks. The new paints are being offered in solid colors with clear-coat finishes as well as with pearl and metallic effects.
