Mack Trucks today announced the expansion of its natural gas-powered truck offerings to on-highway and vocational models. The OEM also said that it has “taken a key step forward” in its hybrid-vehicle development process and that it is continuing to investigate other alternative driveline technologies.
The OEM said it will offer natural gas-powered versions of its on-highway Pinnacle and vocational Granite models in 2013. Both models will be powered by the Cummins Westport ISX12 G engine. Mack noted that customer testing of those trucks is slated to begin this year. The truck maker already offers natural gas-powered TerraPro low-entry and TerraPro cabover refuse-truck models.
