Peterbilt now offers compressed natural gas configurations for its two newest vehicles—the on-highway Model 579 and the vocational Model 567. Both vehicles will be available with the Cummins-Westport ISX12 G, Peterbilt Motors Company announced during the Mid-America Trucking Show.
“Peterbilt leads the heavy duty commercial vehicle industry with the broadest range of natural gas engine and fuel system offerings,” said Peterbilt General Manager and PACCAR Vice President Darrin Siver. “Adding our two new landmark vehicles—the Model 579 and Model 567—to this portfolio will provide our natural gas customers with the industry’s most innovative, advanced vehicles with new state-of-the-art CNG systems.”
Peterbilt showcased a CNG version of its Model 579 in its exhibit at the show. The vehicle was equipped with Quantum Fuel Systems Technologies’ back-of-cab storage system.
Both vehicles comply with all EPA 2013 and CARB emissions regulations and will be available with the following ratings:
- 320 hp at 1,150 lb-ft
- 330 hp at 1,250 lb-ft, 1,350 lb-ft and 1,450 lb-ft
- 350 hp at 1,350 lb-ft and 1,450 lb-ft
- 385 hp at 1,350 lb-ft
- 400 hp at 1,450 lb-ft
The Quantum back-of-cab system provides a lightweight, high-capacity CNG fuel storage solution. It uses Quantum’s compact Q-lite tank technology and can store 123 DGE (diesel gallon equivalents) of fuel and is designed for “drop-and-go” installation. The back-of-cab system can also be installed with Quantum’s single or dual frame rail mounted systems to reach 170 or 216 DGE combined.
“CNG configurations of our Models 579 and 567 are ideal for customers in short- and regional-haul, refuse and construction applications who desire a clean-burning, fuel-saving natural gas engine,” said Robert Woodall, Peterbilt’s Director of Sales and Marketing.
CNG configurations of the Models 579 and 567 will be in production later this year.
