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 the muscle to shoulder heavy-duty vocational and highway workloads.
Mack’s innovative wave piston design delivers 2% improvement in fuel economy and 90% reduction in soot. The waves in the piston bowl redirect flames in the combustion chamber to utilize all available oxygen for a cleaner and more complete burn than standard diesel pistons.
This direct injection system delivers ultra-precise control over fuel injection pressure, timing and volume. The result is more power and efficiency, with less engine noise. Save fuel, gain power and lower emissions.
The Mack PowerLeash™ engine brake provides more braking horsepower through mid-RPM ranges, and weighs 50 pounds less than competitive engine brakes. With better braking over the entire speed range, PowerLeash delivers the most braking ever in a Mack engine brake. You’ll immediately notice how the quiet and responsive PowerLeash engine brake provides more confidence while braking.
Mack’s improved two-speed coolant pump reduces parasitic loss by delivering the right amount of cooling capacity at the right time. When maximum cooling isn’t required, the pump gears down for an extra 0.5 - 0.6% savings in fuel economy.
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.
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.
We take pride in being homegrown. All Mack engines, transmissions and drivelines are assembled in Hagerstown, MD USA.
