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.
The new MP8 HE (High Efficiency) engine has a lower RPM spot between 900 and 1200 RPM to further maximise fuel-efficiency.

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 ADR80-04 and Euro6 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.

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

Low Exhaust and Noise Emission
The MP8 500 more than meets the demand for high performance in conjunction with ADR80/04 (Eu6) 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.
