San Diego-based Metropolitan Transit System (MTS) launched the first
commercial bus with a compressed natural gas (CNG) hybrid-electric drive system developed by ISE Corp.
The ISE engine is a variant of its ThunderVolt hybrid drive system. ISE also integrated the CNG hybrid drive system into a standard 40-foot transit bus that was supplied by MTS. The bus, which is wrapped, will call attention to its environmentally-friendly benefits.
The $1 million CNG hybrid prototype bus will cut significant emissions from the already clean-burning CNG buses in the MTS fleet, providing more power and a quieter ride. The CNG hybrid bus will travel all over the MTS network, providing commuters the opportunity to experience the new technology.
