Mack Trucks is adding a high-efficiency 13-liter engine and its Mack HE+ package as available options on Mack Anthem models, the truck maker announced Thursday.
Anthems equipped with the MP8HE engine and HE+ package deliver up to a 9.5 percent fuel efficiency improvement compared to a base MP8-equipped Anthem model, and Mack Trucks Director of Product Strategy Roy Horton says the combination is SmartWay certified by the U.S. Environmental Protection Agency.
The 13-liter Mack MP8HE engine uses waste energy from the engine’s exhaust system and converts it to mechanical energy that is delivered back to the engine crankshaft as added torque – a process Mack dubs “Mack Energy Recovery Technology.”
“By capturing and using waste energy from the exhaust, Mack’s Energy Recovery Technology allows the engine to run at lower RPM [with] less stress on components,” said Roy Horton, Mack Trucks director of product strategy. “This not only improves fuel efficiency, but also helps improve durability and reliability.”
The HE+ package includes several fuel efficiency-enhancing features, including additional aero components like a roof fairing with trim tab, side fairings with extensions, chassis fairings with ground effects and an aero bumper with spoiler. It also includes Mack Predictive Cruise – an intelligent system that memorizes a route when cruise control is on, storing up to 4,500 hills in its memory. The next time a driver travels the same route, Mack Predictive Cruise engages the ideal shift strategy for maximum fuel efficiency.
The Mack MP8HE and HE+ package are now available for order.
