The Kenworth T680 Next Generation on-highway flagship now is available with the Cummins Westport ISX12N near-zero emissions natural gas engine.
According to Kenworth, its T680 Next Gen establishes a new industry standard by raising the bar for superior fuel efficiency, class-leading performance and bold aerodynamic styling, expanding on the success of the classic T680 model.
The T680 Next Gen offers the 12-liter Cummins Westport ISX12N with ratings up to 400 hp and 1,450 lb-ft of torque. The engine can operate on compressed natural gas (CNG), liquefied natural gas (LNG) and renewable natural gas (RNG).
The ISX12N engine is certified by both the Environmental Protection Agency and California Air Resources Board (CARB). The engine meets CARB’s optional low NOx standard of 0.02 g/bhp-hr.
“The Cummins Westport ISX12N provides an excellent, near-zero emissions solution for fleets and truck operators that order the Kenworth T680 Next Generation for service in line haul, pickup and delivery, and regional haul applications,” said Genevieve Bekkerus, Kenworth marketing director.
Available in day cab, 40-inch, 52-inch and 76-inch sleeper configurations, the T680 Next Gen is standard with the proprietary PACCAR Powertrain featuring the 2021 PACCAR MX-13 engine, PACCAR TX-12 automated transmission and PACCAR DX-40 drive axle.
