Mack recently announced that they will offer natural gas powered models of the Granite and Pinnacle models in the year 2013. Both the models will be using engine of Cummins Westport ISX12 G. Testing of customer is now scheduled to begin in this year. Addition of natural gas powered 12-litre models adds to Mack’s existing line-up of natural gas, which includes Terra Pro Low Entry & Terra Pro Cab over refuse models.

Just like the Mack Terra Pro counterparts of natural gas, natural gas-powered Mack Pinnacle & Granite versions will feature some maintenance-free after treatment & need only 3 way catalyst for meeting EPA 2010 & standards of CARB emissions, says officials. Mack trucks that are natural gas-powered are now available along with CNG (compressed) or LNG (liquefied) systems of fuel.

Kevin Flaherty, the president of Mack Trucks North American marketing and sales, says that Mack has big history in the alternative technologies of drive line, especially natural gas. They have offered them natural gas since it has become clear that it is viable solution of energy in segment of refuse. Now the customers with in LTL, regional haul, & segments of construction will have natural gas benefits combined along with performance and power that they are expecting from Mack.
