Peterbilt Motors Company introduced two new medium duty vehicles powered by compressed natural gas during the Mid-America Trucking Show - the Model 337 and the Model 348. Both vehicles are now in production and can be configured as trucks or tractors.
“Peterbilt is the established market leader in natural-gas powered Class 8 commercial vehicles and we’re pleased to bring this expertise to medium duty markets,” said Darrin Siver, Peterbilt general manager and PACCAR vice president. “Peterbilt’s award-winning medium duty trucks – renowned for their versatility, quality and performance – are now available for customers who want to operate with cost effective, environmentally sound CNG. This is an ideal choice for dump, refuse and short- and regional-haul operations.”
Peterbilt displayed a CNG-powered Model 337 in its exhibit at the show in Louisville, Ky. According to Scott Newhouse, Peterbilt chief engineer, the new medium duty models are optimized for this configuration with 110" BBCs.
“The CNG Models 337 and 348 give Peterbilt the industry’s most competitive portfolio of natural gas vehicles,” Newhouse said. “The dimensions provide a BBC 2" shorter than any competitive model and a cab height that is 2.5" lower.”
Newhouse said the optimized spec, including steering geometry that provides up to a 50-degree turning angle, provides improved maneuverability in congested city and jobsite operations. Both the Models 348 and 337 are powered by the Cummins Westport ISL-G with 320hp and 1,000 ft/lb of torque. The engine complies with EPA 2010, 2013 and CARB emissions regulations.
