CNG-Fueled Kenworth T680 and Peterbilt 579 at MATS 2014
Paccar’s Kenworth and Peterbilt units showed new natural gas trucks at MATS 2014, last week’s Mid-America Trucking Show in Kentucky. The new heavy duty offerings are powered by the 11.9-liter ISX12 G engine from Cummins Westport.
Kenworth showed a compressed natural gas-fueled T680, a vehicle platform launched just two years ago. Peterbilt unveiled the new 579 and 567.
“Our customers find it very appealing to be able to choose cost-efficient natural gas combined with the fuel-saving aerodynamics of the Kenworth T680,” Kenworth specialty markets national sales manager Andy Douglas said in a release.
‘New Benefits & Cost-Savings Opportunities’
The T680 was introduced in day cab and 76-inch sleeper configurations, and a 52-inch mid-roof sleeper option was added last year.
“This important expansion of our T680 product line will provide customers in various applications with new benefits and cost-savings opportunities,” Douglas said.
Kenworth also offers the ISX12 G engine in the T660 tractor and the Kenworth T800 short hood. Kenworth works with such companies as Agility Fuel Systems, McNeilus and Trilogy Engineered Solutions to provide natural gas tanks and fueling systems.
CNG for New Peterbilt 579 and 567
Peterbilt said at MATS that it is “advancing its leadership in the natural gas truck markets” with CNG version of its two newest vehicles – the on-highway Model 579 and the vocational Model 567.
“Peterbilt leads the heavy duty commercial vehicle industry with the broadest range of natural gas engine and fuel system offerings,” said Peterbilt GM and Paccar VP Darrin Siver. The firm claims 40% of the Class 6-8 natural gas truck market.
“Our breadth of our natural-gas vehicle offerings, the most of any manufacturer, helps ensure we will meet the application and business requirements of most every industry segment,” Siver said.
“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.”
Production Later This Year
“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 Peterbilt sales and marketing director Robert Woodall.
A CNG version of the Peterbilt 579 was shown at MATS with a 123-DGE/diesel gallon equivalent back-of-cab fuel cylinder array from Quantum.
Peterbilt said it will commence production of CNG versions of its 579 and 567 models trucks later this year, with a range of 320- to 400-horsepower ratings.
