Cummins Westport Inc. announced that North American Bus Industries Inc. (NABI) has ordered 260 compressed natural gas CWI ISL G engines for NABI's CompoBus vehicles.
The NABI CompoBus is a 45-foot vehicle made from a lightweight composite material that weighs roughly the same as the company's traditional 40-foot bus, enabling it to provide a lower operating cost per passenger mile as compared to buses with traditional steel structures.
