STE. THERESE, QC. A new interior with a more automotive feel leads the changes for Peterbilt Motors’ two new medium-duty trucks, the Model 337 and Model 347. Now entering production at the Paccar truck plant here, the new models also offer improved visibility, a multiplexed electrical system and a redesigned HVAC with higher output, according to Peterbilt.
The Model 337, which replaces the Model 335, is offered in GVWs ranging from 26,000 to 33,000 lbs. It can be speced with either the 6.7-liter Paccar PX-6 diesel (240-325 HP) or the 8.3-liter Paccar PX-8 (240 to 360 HP).
Replacing the Model 340, the 2010 Model 348 is available of either a truck or tractor with GVWs starting at 35,000 lbs. Power is supplied by the proprietary PX-8.
Common to both new medium-duties is an all-aluminum cab derived from Peterbilt’s heavy-duty trucks. It features a lower cab-door belt line that improves side sight lines by 17%, according to Peterbilt, as well as a larger rear window and improved forward visibility. Inside, the redesigned cab includes an all-new dashboard with an integrated driver information display and multiplexed electronics with a J1939 bus for access to vehicle diagnostic and operational information.

The 2010 versions of the Model 337 and Model 348 are being fitted with EPA07-compliant versions of the Paccar diesels. Starting in January, the company will begin installing 2010-compliant engines using selective catalytic reduction (SCR) technology. Those trucks will also get a new chassis design and will be designated as 2011 models.
