DENTON, Texas — Peterbilt has introduced its new Model 335 hybrid electric tractor, which the truck manufacturer called “ideally suited” for applications that require a trailer, such as beverage and regional-haul deliveries.

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, according to Peterbilt. The system stores energy during stopping through a process called regenerative braking, and then reuses it for acceleration. The company says that fuel use, emissions and noise are greatly reduced.

“Peterbilt’s new class 7 Model 335 hybrid electric tractor provides local haul applications, the benefits of a hybrid system, combined with traditional Peterbilt quality, durability, performance and styling,” said Bill Jackson, Peterbilt general manager and PACCAR vice-president.

“Peterbilt’s expanding hybrid portfolio is evidence in our commitment to integrating hybrid solutions into fuel-efficient vehicle designs.”

In addition, Peterbilt states that the Eaton hybrid electric power system, the Model 335 hybrid electric tractor, features the in-dash, seven-inch, PACCAR proprietary hybrid system monitor. The display provides information regarding fuel economy and battery state of charge, allowing the driver to modify behaviour, 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.
