‘Bulldog Walks the Walk’ on Alternative Drivelines
Mack Trucks pledged to expand its natural gas-powered offerings, and said it “has taken a key step forward” in hybrids as more trucks are to be delivered to New York City for testing.

Mack Trucks promises natural gas ISX12 G-powered versions of its Granite construction and Pinnacle over-the-road trucks for 2013.

Mack said it’s planning natural gas versions of its Pinnacle and Granite models for on-highway and construction applications in 2013. Both will be powered by the new 11.9-liter ISX12 G engine by Cummins Westport, Inc.

Customer testing is to begin this year, Mack said.

Mack has offered natural gas-powered Mack TerraPro low entry and TerraPro cabover refuse models, with CWI’s 8.9-liter ISL G engine, since mid-2009.

Mack Trucks is the latest to offer dedicated-natural gas trucks powered by the 11.9-liter ISX12 G engine by Cummins Westport.

“Mack has a long history in alternative driveline technologies, and in particular, natural gas,” Mack Trucks North America sales and marketing president Kevin Flaherty said in a release.

“We’ve offered natural gas since it became clear that it was a viable energy solution in the refuse segment,” Flaherty said. Now regional haul, LTL (less than truckload) and construction segment customers will be able to select natural gas-fueled Macks, he said.

Mack says it 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.

More Diesel-Electric Hybrids for New York

In addition, Mack said it continues to move forward on its diesel-electric hybrid TerraPro models, recently delivering additional low entry test units to the New York City Department of Sanitation. The Mack diesel-electric hybrid technology provides up to a 30% fuel economy improvement in such stop-and-go applications as refuse, Mack says, with a corresponding greenhouse gas emissions benefit.

“We listen to what our customers want and develop the technologies best suited for their needs,” Flaherty said. “Mack’s alternative driveline technologies represent an ongoing evolution built upon our proven experience.”

Mack Trucks, Inc. is part of the Volvo Group. Volvo Trucks has also promised vehicles with CWI’s ISX12 G engine.
