KANSAS CITY, Mo. — Thomas Built Buses is developing another alternative-fuel offering for its line of school buses: a compressed natural gas (CNG) Type C.

A company spokesperson said that Thomas Built anticipates being the first to market with a CNG-powered Type C (also known as conventional) school bus.

The Saf-T-Liner C2 CNG is slated to go into production in the first quarter of 2016. It will be CARB-certified and will exceed EPA 2013 emissions requirements, according to the company.

The bus will be powered by a Cummins Westport ISB6.7 G engine, with 200 to 240 horsepower, and an Allison 2500 transmission.

Thomas Built currently offers CNG models of its Saf-T-Liner HDX, which is a Type D school bus, and its Minotour, which is a Type A.
