• Even Distribution of Power

    MP® delivers consistent power and torque across a wide operating range that can be tuned to your needs for the right mix of power and high fuel efficiency.

  • Serious Weight Savings

    The lighter the engine, the more you can load. The MP®8 now weighs 88 pounds less than the previous version, which means more payload per trip day in and day out—plus better operational efficiency and more revenue.

  • Assembled in the USA

    We take pride in being homegrown. All Mack engines, transmissions and drivelines are assembled in Hagerstown, MD USA.
