The recent Alternative Clean Transportation (ACT) Expo in Washington, D.C., was the perfect platform for Mack Trucks to showcase its liquefied natural gas-powered powered Mack Pinnacle model to the transportation community.
The on-highway tractor displayed at the show was built for UPS, which put the vehicle into test service in Greensboro, N.C. The truck has been running two 350- to 400-mile shifts per day, hauling loads of up to 80,000 pounds with 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 Mack natural gas Pinnacle model is equipped with a Cummins Westport ISX12 G engine and offers maintenance-free after treatment that meets both EPA 2010 and CARB emissions standards. Four hundred horsepower and 1,450 pounds-feet of torque contribute to a balance power for LTL and regional haul applications, as well as fuel savings for customers.
LNG currently costs 30 to 40 percent less than diesel, based on a diesel gallon equivalent, which offers its users a significant return on investment.
Mack plans to introduce a natural gas-powered version of the Mack Granite model as well.
