Additional Freightliner Cascadia 113 compressed natural gas (CNG) tractors have been adopted by Con-way’s fleet.

Freightliner began production of the Freightliner Cascadia 113 natural gas-powered tractors in August 2013 and these units are the first Cascadia day cabs with factory-installed CNG tanks to hit the road.

The tractors are equipped with the Cummins Westport ISX 12 G engine and will be used in the Texas market.

It is the second deployment of Freightliner CNG-powered units for Con-way Freight, which since 2011 has operated Freightliner medium-duty tractors, powered by the Cummins Westport ISL G 8.9L engine, on a test basis in the Chicago market.

“Freightliner has been an excellent partner as we have explored how natural gas-powered trucks fare in our operating environment,” said Randy Mullett, Con-way’s vice president of government relations and public affairs. “These new units will allow us to expand our knowledge base, particularly with respect to how the larger CNG-powered engines perform in our line-haul network.
