The addition of the 12-liter natural gas-powered models expands Mack’s current natural gas solutions to on-highway and construction applications. Mack already offers natural gas-powered MACK® TerraPro™ Low Entry and MACK® TerraPro® Cabover refuse models.

Like their Mack TerraPro natural gas counterparts, the Mack natural gas-powered Pinnacle and Granite models will feature maintenance-free aftertreatment and require only a three-way catalyst to meet EPA 2010 and CARB emissions standards, setting a new benchmark for lower alternative fuel vehicle lifecycle costs and improving customers’ return on investment. Mack’s natural gas-powered trucks are available with compressed (CNG) or liquefied (LNG) fuel systems.

“Mack has a long history in alternative driveline technologies, and in particular, natural gas,” said Kevin Flaherty, president, Mack Trucks North American Sales & Marketing. “We’ve offered natural gas since it became clear that it was a viable energy solution in the refuse segment. Now customers within the regional haul, LTL and construction segments will have the benefits of natural gas combined with the power and performance they expect from Mack.”

Mack also is investigating other alternative driveline technologies, including high pressure direct injection, which uses a combination of natural gas and a small amount of diesel in the combustion process, and DME (dimethyl ether), which can be produced from natural gas.
