Mack Trucks unveiled its highly anticipated 12-liter natural gas-powered Mack Pinnacle Axle Back model during the 2013 Mid-America Trucking Show recently. The natural gas-powered Mack Pinnacle, offering a liquefied natural gas (LNG) system for on-highway applications, was built for UPS.

The addition of the natural gas-powered Pinnacle expands Mack’s natural gas line-up to the highway segment. Mack already offers natural gas-powered Mack TerraPro Low Entry and TerraPro Cabover refuse models, and later in 2013 plans to introduce a natural gas-powered version of the Mack Granite model.

Ideal for regional haul and LTL, the Mack Pinnacle is equipped with the Cummins Westport ISX12 G engine and available for order with either an LNG or compressed natural gas (CNG) fuel system. The maintenance-free aftertreatment, requiring only a three-way catalyst to meet EPA 2010 and CARB emissions standards, combined with low-cost natural gas, reduces vehicle lifecycle costs and thereby improves return on investment.
