Mack shows LNG-powered Pinnacle at ACT

WASHINGTON, DC. Mack Trucks showed off a liquefied natural gas (LNG) powered Mack Pinnacle model here this week at the Alternative Clean Transportation (ACT) Expo.

The displayed tractor was built for UPS and has been in test service in Greensboro, NC for the package delivery giant. The truck has been running two 350-400 mi. shifts per day, hauling loads of up to 80,000 lbs. hauling both single and double trailers. UPS has since placed an order for 122 additional units scheduled to be delivered throughout the fourth quarter of 2013. 

The tractor is equipped with a Cummins Westport ISX12 G engine and offers maintenance-free aftertreatment meeting both EPA 2010 and CARB emissions standards. The powerplant offers 400 hp. and 1,450 lbs.-ft of torque.

“Because ACT Expo is North America’s largest alternative fuel and clean vehicle technology show, we felt it was an important venue to demonstrate the purposeful design that makes our Mack Pinnacle a leading natural gas-powered highway truck in the market,” said Roy Horton, Mack powertrain product marketing manager. “We have a long-standing relationship with UPS on the diesel side, and we take great pride in the fact that they’ve turned to us for natural gas vehicles as well.”
