Wave Piston

The next evolution in piston design

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.
Common Rail Fuel System

Uncommon power and efficiency

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.
ClearTech™ One

Do more with less

This next-generation single box exhaust aftertreatment system combines Selective Catalytic Reduction (SCR) technology and Diesel Particulate Filter (DPF) to deliver near-zero emissions and low maintenance in a lighter, more compact unit.
Variable Geomoetry Turbocharger

A turbo for all speeds

Mack’s electronically controlled Variable Geometry Turbocharger incorporates the latest technology to control turbo boost at all RPM ranges and engine loads, so you can have power and efficiency at any speed.

Serious Weight Savings

The evolved 11L MP®7 drops 51 lbs. and saves 2-5% in fuel consumption, continuing its stellar reputation for weight-sensitive applications.
Smaller Carbon Footprint

The latest MP®7 engines are specially designed to meet the EPA 2017 standards. They reduce greenhouse gas emissions (CO2), helping to make your trucks some of the cleanest and most fuel-efficient on the road.
Assembled in the USA

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