Improved Fuel Efficiency with Mack MP8HE and HE+ Package

June 14, 2018


GREENSBORO, NC (June 14, 2018) – To help customers realize maximum fuel efficiency, Mack Trucks today introduced the Mack® MP®8HE 13-liter engine and the Mack HE+ package for Mack Anthem® models. Mack Anthem models spec’d with the MP8HE engine and HE+ package deliver up to a 9.5 percent improvement in fuel efficiency and achieve the U.S. Environmental Protection Agency’s SmartWay designation.

The Mack MP8HE engine employs Mack Energy Recovery Technology, which captures waste energy from the engine’s exhaust and converts it to mechanical energy that is delivered back to the engine crankshaft as additional torque. The HE+ package consists of a number of fuel efficiency-enhancing features, including additional aero components that take the superior aerodynamic advantage of the Mack Anthem a step further.

“Customers continue to place a heavy emphasis on improving fuel efficiency, particularly now, as we see fuel prices steadily climbing,” said Jonathan Randall, Mack Trucks senior vice president, North American sales and marketing. “Combining our advanced, yet reliable Energy Recovery Technology with additional aerodynamic features, we’re able to achieve significant fuel savings without compromising performance.”

“By capturing and using waste energy from the exhaust, Mack’s Energy Recovery Technology allows the engine to run at lower RPM for 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 Mack MP8HE is available exclusively with the Mack mDRIVE™ automated manual transmission. Fully integrated with the engine, the mDRIVE contributes to overall efficiency by constantly monitoring speed, grade and load to identify ideal shift points and help ensure the truck is always in the right gear. The mDRIVE also enables the lower, downsped cruise RPM to take advantage of the extra torque provided by the Energy Recovery Technology.

The Mack HE+ package also features 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.

In developing the Anthem model, Mack engineers pored over data to design a truck that more easily cuts through the wind. Despite its bold, muscular looks, the Anthem includes a number of aerodynamic enhancements for improved fuel efficiency. Mack’s HE+ package builds on these to deliver the ultimate in efficiency.

“The additional features in our HE+ package, including a roof fairing with trim tab, side fairings with extensions, chassis fairings with ground effects and an aero bumper with spoiler, together with the MP8HE, deliver a fuel efficiency improvement of up to 9.5 percent compared to a base MP8-equipped Anthem model,” Horton said.

The Mack MP8HE and HE+ package are now available for order. For more information, please visit or the nearest Mack dealer.
