MP8

The MP®8 engine is a legend on roads everywhere. With plenty of horsepower and torque across a wide operating range, the MP®8 delivers high reliability and excellent fuel economy and is suited to line haul applications as well as urban short haul and construction operations.

  • 435-535 Horsepower
  • 1,655-1,920 lb.-ft. torque
  • 13L displacement
  • Euro 5 SCR (Selective Catalytic Reduction)

  • Proven Performance

    Using Mack’s long proven history of engine development, the MP8 MaxiCruise, was especially selected for Australian conditions. It provides superior performance for both on-road and vocational applications. This unique versatile performer provides a wider operating range and a “Humped” power curve for ease of operation and a generous fuel sweet spot between 1000 ~ 1400 rpm.

    • Electronics that Raise your Engine’s I.Q.

      The MP8 features MACK V-MAC® IV Engine Management System which is a totally electronically controlled system that provides precise and efficient engine control. The V-MAC® IV ECM controls the fuel injection entirely via electromagnetic valves in each injector.

      • Mack PowerLeash

        Designed specifically to work with Mack’s MP engines, PowerLeash cuts response time by up to half. This delivers near-instantaneous braking, yet weighs much less than conventional systems, has fewer moving parts and delivers superior braking power over the entire speed range.

        • SCR Technology

          The MP engine series uses Selective Catalytic Reduction (SCR) technology, which meets the Australian requirements by ADR80-03 and Euro5 regulations.

          • 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.

          • Low Exhaust and Noise Emission

            The MP8 500 more than meets the demand for high performance in conjunction with ADR80/03 (Eu5) low exhaust and ADR83 noise emissions. The MP8 500 satisfies noise requirements without needing complex encapsulation. The crankshaft and camshaft have viscous vibration dampers which minimise noise and vibration. The low noise is particularly evident at idle.

          • More Uptime

            Extended service intervals through a Mack Optimised Service Plan (MOSP) results in maximum uptime.
