“That is why the 12-liter Cummins Westport engine that is supposed to come out in April is exciting for so many people,” he adds. “In many cases, the 8.9-liter is too small and the 15-liter is too big.” A 12-liter natural gas engine hits a sweet spot for many in the Class 8 truck market.
Mack is among several companies that will capitalize on the new 12-liter offering. “We remain on track to provide the ISX12G-equipped Mack Pinnacle and Granite models this year,” says Horton.
Freightliner is also expanding its lineup. “We have been building natural gas trucks for the vocational market over the last four years in our M2 112 truck with the ISL G,” says Treinen. “In late 2011, we began production on the all-new 114D SBA — designed for severe-duty applications — with the ISL G. We are planning on expanding the 114SD lineup to include the ISX12 G.”
