Overview

​In 2016, Cummins Westport will introduce a new dedicated natural gas engine for transit, shuttle and school bus, medium-duty truck, and vocational vehicle markets. Based on the Cummins ISB6.7 diesel platform, the Cummins Westport ISB6.7 G will offer up to 240 hp (179kW) and 560 lb-ft (759 Nm) of torque, and will be available with automatic transmissions. Certified at launch to 2016 U.S. Environmental Protection Agency (EPA) and California Air Resources Board emissions standards, the ISB6.7 G will also meet 2016 EPA GHG requirements.

The ISB6.7 G features the same advanced combustion controls with Three-Way Catalyst (TWC) as Cummins Westport’s ISL G & ISX12 G engines. It operates on 100 percent natural gas, which can be carried on the vehicle in either compressed or liquefied form (CNG / LNG respectively). It can also run on 100 percent biomethane or renewable natural gas, which meets published Cummins fuel specifications.
