The on-highway tractor displayed at the show was built for UPS. UPS put the vehicle into test service in Greensboro, N.C., and the truck has been running two 350-400 mile shifts per day, hauling loads of up to 80,000 lbs. with both single and double trailers, the company says. UPS has since placed an order for 122 additional units scheduled to be delivered throughout the fourth quarter of 2013.
The Pinnacle is equipped with a Cummins Westport ISX12 G engine and offers maintenance-free after treatment meeting both EPA 2010 and CARB emissions standards, Mack says. Four hundred horsepower and 1,450 lb.-ft. of torque are said to offer the perfect balance of power for LTL and regional haul applications, as well as fuel savings for customers. Mack says LNG currently costs 30-40 percent less than diesel based on a diesel gallon equivalent, enabling customers to receive a significant return on investment.
“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,” says 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.”
Mack has been offering natural gas-powered TerraPro models since 2009, and says it plans to introduce a natural gas-powered version of the MACK Granite as well.
