New Medium-Duty Hybrid From Peterbilt

Posted on November 5, 2008

Peterbilt Motors has introduced a new Peterbilt Model 335 hybrid electric tractor targeted toward applications such as beverage and regional-haul deliveries that require a trailer. Now available for immediate order through Peterbilt’s Dealer Network, the new Model 335 hybrid electric tractor utilizes the Eaton’s Hybrid Electric Power System with an electric motor that assists the PACCAR PX-6 engine with supplemental torque for up to 25% fuel economy gains in local haul applications, the company said. The system stores energy during stopping through regenerative braking, then reuses it for acceleration.

In addition to the Eaton Hybrid Electric Power System, the Model 335 hybrid electric tractor features the in-dash 7 in. 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.

Peterbilt’s production hybrids include the Model 330 Hybrid Electric as a non-CDL option for short haul pick-up and delivery applications, and the Model 335 Hybrid Electric for pick-up and delivery, beverage applications and municipal and utility operations. Peterbilt is also developing two heavy duty hybrid configurations; a Model 320 Hydraulic Launch Assist (HLA) vehicle for vocational and stop-and-go applications, and a Model 386 Hybrid Electric vehicle for long-haul applications.
