Engineered for a new era of efficiency

With advances in design and engineering, the new MP8HE engine earns up to 11 miles per gallon.
Improved Engineering

The improved wave piston design delivers a higher compression ratio inside a lighter, more efficient engine.

Advanced Efficiency

The updated turbo compound, auxiliary drive, gear ratio and EGR valve all work to deliver greater efficiency.

Reduced Emissions

The redesigned oil filtration system features two oil filters and uses a lesser viscosity oil for reduced consumption.

Evolved wave piston design

Evolved wave piston design

Mack’s innovative wave piston design redirects flames in the combustion chamber to utilize all available oxygen for a cleaner and more complete burn than standard diesel
pistons. The result delivers improved fuel economy and reduced emissions.

Next-Generation Energy Recovery Technology (ERT)

Next-Generation Energy Recovery Technology (ERT)

Capturing heat that would otherwise be lost, the MP8HE’s ERT feature converts exhaust emissions to mechanical energy and delivers it back to the crankshaft as torque. This
process enables the engine to operate at 1,000-1,100 RPM, saving fuel without sacrificing performance.

Power and performance Graph

Power and performance

The MP8HE 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.

Common Rail fuel system

Built to fuel efficiency

The direct injection common rail fuel system delivers ultra-precise control over fuel injection pressure, timing and volume. The result is more power and efficiency with less engine noise and lower emissions.

Cleaner emissions with ClearTech One

Cleaner emissions with ClearTech One

Mack’s improved exhaust aftertreatment system (EATS) is 17lbs lighter and takes up less space, which saves you fuel and money while improving flexibility.
