DENTON, TX, June 12, 2009 – Peterbilt Motors Company displayed the latest addition to its hybrid lineup, the Peterbilt Model 335 hybrid tractor, at CALSTART and the Hybrid Truck Users Forum’s (HTUF) “Hybrids on the Hill” event to demonstrate the progress of hybrid technology in the medium and heavy-duty truck market, and explore how federal action can best support widespread commercialization.

“The event provided Government representatives a hands-on experience that showcased the ease of operation and environmental friendliness that is currently available to the market with Peterbilt’s hybrid production vehicles,” said Larry Reding, assistant general manger of sales and marketing, Peterbilt Motors Company.  “Peterbilt has the industry’s most comprehensive lineup of hybrid vehicles, including three medium-duty models and two heavy-duty hybrid platforms that fully cover applications from pick up and delivery, utility work truck, municipal refuse, and potentially line-haul operation.”

The latest addition to Peterbilt’s hybrid lineup, the new Model 335 hybrid tractor, utilizes Eaton’s Hybrid Electric Power System with an electric motor that assists the PACCAR PX-6 engine with supplemental torque for up to 40 percent fuel economy gains. The system stores energy during stopping through a process called regenerative braking, and then reuses it for acceleration.  

In addition to the Eaton Hybrid Electric Power System, the Model 335 hybrid tractor features the in-dash 7-inch PACCAR proprietary Hybrid System Monitor.  The display provides information regarding fuel economy and battery state of charge, allowing the driver to modify behavior to maximize fuel economy through optimized use of the system.  The display also provides full diagnostic capabilities for the hybrid system including system operating status.

Additionally, Peterbilt currently offers in full production the Model 330 and Model 335 hybrid vehicles.   The Model 335 hybrid utilizes components that provide an up to a 50 percent improvement in fuel efficiency, when configured for a utility application.  These fuel savings are realized through both an on-road fuel economy gain, and an 80 percent reduction in engine idling, through electric operation of the Power Take-Off (PTO) using the on-board lithium-ion batteries.  The Model 330 hybrid is available with a 26,000 pound GVW rating, and can be configured for non-CDL operation with hydraulic brakes for a greater range of driver options.  Launching the vehicle electrically in an urban driving cycle can easily achieve fuel economy benefits in excess of 30 percent. 

Peterbilt is also developing two heavy duty hybrid configurations; a Model 320 hydraulic launch assist (HLA) vehicle for vocational and stop-and-go applications with production availability in late 2009, and a Model 386 hybrid electric developmental platform for long-haul applications.
